Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis Of Presentation	Basis of Presentation Unaudited Interim Condensed Consolidated Financial Statements We have prepared the accompanying unaudited interim condensed consolidated financial statements in accordance with U.S. GAAP, and with SEC rules and regulations, which allow for certain information and footnote disclosures that are normally included in annual financial statements prepared in accordance with GAAP to be condensed or omitted. In our opinion, these unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements for the fiscal year ended September 25, 2015 and include all adjustments necessary for fair presentation. The accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with our consolidated financial statements for the fiscal year ended September 25, 2015 , which are included in our Annual Report on Form 10-K filed with the SEC. The results for the fiscal quarter ended January 1, 2016 are not necessarily indicative of the results to be expected for any subsequent quarterly or annual financial period, including the fiscal year ending September 30, 2016 . Principles of Consolidation The unaudited interim condensed consolidated financial statements include the accounts of Dolby Laboratories, Inc. and our wholly owned subsidiaries. In addition, we have consolidated the financial results of jointly owned affiliated companies in which our principal stockholder has a controlling interest. We report these controlling interests as a separate line in our consolidated statements of operations as net income attributable to controlling interest and in our consolidated balance sheets as a controlling interest. We eliminate all intercompany accounts and transactions upon consolidation. Operating Segments We operate as a single reporting segment, and thus all required financial segment information is included in our unaudited interim condensed consolidated financial statements. This determination reflects the fact that our CODM, our Chief Executive Officer, evaluates our financial information and resources, and assesses the performance of these resources on a consolidated basis. Use of Estimates The preparation of our financial statements in accordance with GAAP requires management to make certain estimates and assumptions that affect the amounts reported and disclosed in our unaudited interim condensed consolidated financial statements and accompanying notes. Significant items subject to such estimates and assumptions include estimated selling prices for elements sold in ME revenue arrangements; valuation allowances for accounts receivable; carrying values of inventories and certain property, plant, and equipment, goodwill and intangible assets; fair values of investments; accrued liabilities including liabilities for unrecognized tax benefits, deferred income tax assets and liabilities and stock-based compensation. Actual results could differ from our estimates. Fiscal Year Our fiscal year is a 52 or 53 week period ending on the last Friday in September. The fiscal periods presented herein include the 14 week period ended January 1, 2016 and the 13 week period December 26, 2014. Our fiscal year ended September 25, 2015 (fiscal 2015 ) consisted of 52 weeks while our fiscal year ending September 30, 2016 (fiscal 2016 ) will consist of 53 weeks. Reclassifications We have reclassified certain prior period amounts within our consolidated financial statements and accompanying notes to conform to our current period presentation. These reclassifications did not affect total revenue, operating income, operating cash flows or net income.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2 . Summary of Significant Accounting Policies We continually assess any ASUs or other new accounting pronouncements issued by the FASB to determine their applicability and impact on us. Where it is determined that a new accounting pronouncement will result in a change to our financial reporting, we take the appropriate steps to ensure that such changes are properly reflected in our consolidated financial statements or notes thereto. Recently Issued Accounting Standards Adopted Standards Balance Sheet Classification - Deferred Taxes. During the first quarter of fiscal 2016, we elected to early-adopt ASU 2015-17, Balance Sheet Classification of Deferred Taxes . The new standard requires classification of all deferred tax assets and liabilities as non-current, which represents a change from our historical presentation whereby certain of our deferred tax assets and liabilities were classified as current, and the remainder were classified as non-current. We elected a transition method to apply the changes from the new standard on a retrospective basis, and upon adoption, reclassified $97.1 million of deferred tax assets from current assets to non-current assets on our consolidated balance sheet as of September 25, 2015. With the exception of the impact from the adoption of ASU 2015-17 discussed above, there have not been any changes to our significant accounting policies from those that were described in our Form 10-K for the prior fiscal year ended September 25, 2015 . Standards Not Yet Effective Revenue Recognition. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This new standard will replace existing revenue recognition guidance in U.S. GAAP when it becomes effective, and may also impact the accounting for certain direct costs associated with revenues. The new standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that this standard will have on our consolidated financial statements and related disclosures, and have yet to select a transition method or determine the effect of the standard on our ongoing financial reporting. The new standard is effective for us, and we intend to adopt it beginning September 29, 2018. Although permitted, we do not intend to early adopt the new standard beginning September 30, 2017. Consolidation. In February 2015, the FASB issued ASU No. 2015-02, Consolidation: Amendments to the Consolidation Analysis , which amends the consolidation requirements in ASC 810 and significantly changes the consolidation analysis required under U.S. GAAP. Among others, the ASU significantly amends how variable interests held by a reporting entity’s related parties or de facto agents affect its consolidation conclusion. The ASU is effective for us on October 1, 2016. Early adoption is permitted, including adoption in an interim period. We have not yet selected the timing, the transition method or determined the effect of the standard on our ongoing financial reporting. Inventory. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory , which affects reporting entities that measure inventory using first-in, first-out (FIFO) or average cost. Specifically, ASU 2015-11 requires that inventory be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using LIFO or the retail inventory method. The amendments in this Update are effective for us beginning September 30, 2017, and early adoption is permitted. We are currently evaluating the impact of adoption on our consolidated financial statements.

Inventory with a consumption period expected to exceed twelve months is recorded within other non-current assets in our consolidated balance sheets. In addition to the amounts shown in the table above, we have included $1.4 million and $1.4 million of raw materials inventory within other non-current assets in our consolidated balance sheets as of January 1, 2016 and September 25, 2015 , respectively. Based on anticipated inventory consumption rates, and aside from existing write-downs due to excess inventory, we do not believe that material risk of obsolescence exists prior to ultimate sale.

Fair Value, Assets, Liabilities and Stockholders' Equity Measured on Recurring Basis [Abstract]
Investments & Fair Value Measurements	Investments & Fair Value Measurements Investment Strategy. Under our investment management strategy, we use cash holdings to purchase investment grade securities that are diversified among security types, industries and issuers. Each of the investments within our investment portfolio is measured at fair value, and is recorded within cash equivalents, short-term investments, and long-term investments in our consolidated balance sheets. With the exception of our mutual fund investments held in our supplemental retirement plan, all of our investments are classified as available-for-sale securities. Investments held in our supplemental retirement plan are classified as trading securities. Our investments primarily consist of municipal debt securities, corporate bonds, United States agency securities and commercial paper. In addition to the security types noted above, our cash and cash equivalents also consist of highly-liquid money market funds. Consistent with our investment policy, none of the municipal debt investments that we hold are supported by letters of credit or standby purchase agreements.

Fair Value Hierarchy. Fair value is the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants at the measurement date. We minimize the use of unobservable inputs and use observable market data, if available, when determining fair value. We classify our inputs to measure fair value using the following three-level hierarchy: Level 1: Quoted prices in active markets at the measurement date for identical assets and liabilities. We base the fair value of our Level 1 financial instruments, which are traded in active markets, using quoted market prices for identical instruments. Level 2: Prices may be based upon quoted prices in active markets or inputs not quoted on active markets but are corroborated by market data. We obtain the fair value of our Level 2 financial instruments from a professional pricing service, which may use quoted market prices for identical or comparable instruments, or model driven valuations using observable market data or inputs corroborated by observable market data. To validate the fair value determination provided by our primary pricing service, we perform quality controls over values received which include comparing our pricing service provider’s assessment of the fair values of our investment securities against the fair values of our investment securities obtained from another independent source, reviewing the pricing movement in the context of overall market trends, and reviewing trading information from our investment managers. In addition, we assess the inputs and methods used in determining the fair value in order to determine the classification of securities in the fair value hierarchy. Level 3: Unobservable inputs are used when little or no market data is available and reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. Securities In Gross Unrealized Loss Position. We periodically evaluate our investments for other-than- temporary declines in fair value. The unrealized losses on our available-for-sale securities were primarily the result of unfavorable changes in interest rates subsequent to the initial purchase of these securities. The following table presents the gross unrealized losses and fair value for those available-for-sale securities that were in an unrealized loss position as of January 1, 2016 and September 25, 2015 (in thousands): January 1, 2016 September 25, 2015 Investment Type Fair Value Gross Unrealized Losses (1) Fair Value Gross Unrealized Losses (1) U.S. agency securities $ 29,302 $ (186 ) $ 19,005 $ (17 ) Commercial paper 13,832 (11 ) — — Corporate bonds 195,014 (666 ) 148,034 (403 ) Municipal debt securities 60,886 (94 ) 35,476 (60 ) Total $ 299,034 $ (957 ) $ 202,515 $ (480 ) (1) Our available-for-sale securities in an unrealized loss position were in such position for less than twelve months as of both January 1, 2016 and September 25, 2015 . Although we had certain securities that were in an unrealized loss position as of January 1, 2016 , we expect to recover the full carrying value of these securities as we do not intend to, nor do we currently anticipate a need to sell these securities prior to recovering the associated unrealized losses. As a result, we do not consider any portion of the unrealized losses at either January 1, 2016 or September 25, 2015 to represent an other-than-temporary impairment, nor do we consider any of the unrealized losses to be credit losses. Investment Maturities. The following table summarizes the amortized cost and estimated fair value of the available-for-sale securities within our investment portfolio based on stated maturities as of January 1, 2016 and September 25, 2015 , which are recorded within cash equivalents and both short and long-term investments in our consolidated balance sheets (in thousands): January 1, 2016 September 25, 2015 Range of maturity Amortized Cost Fair Value Amortized Cost Fair Value Due within 1 year $ 187,978 $ 187,904 $ 158,957 $ 159,090 Due in 1 to 2 years 133,489 133,256 173,571 173,577 Due in 2 to 3 years 130,915 130,395 143,879 143,752 Total $ 452,382 $ 451,555 $ 476,407 $ 476,419

Patent Portfolio Acquisition. On September 30, 2015 , we completed an asset purchase of a patent portfolio that fits within our existing patent licensing programs for total consideration of $105.0 million . These assets are categorized within the "Acquired patents and technology intangible asset class", and will be amortized over their weighted-average useful life of 9.0 years . Other. During the first quarter of fiscal 2016, we also acquired other intangible assets for cash consideration of $0.3 million , which will be amortized over their weighted-average useful life of 18.0 years .

Stockholders' Equity And Stock-Based Compensation [Abstract]
Stockholders' Equity And Stock-Based Compensation	Stockholders' Equity & Stock-Based Compensation We provide stock-based awards as a form of compensation for employees, officers and directors. We have issued stock-based awards in the form of stock options and RSUs under our equity incentive plans, as well as shares under our ESPP. Common Stock - Class A and Class B Our Board of Directors has authorized two classes of common stock, Class A and Class B. At January 1, 2016 , we had authorized 500,000,000 Class A shares and 500,000,000 Class B shares. At January 1, 2016 , we had 52,089,249 shares of Class A common stock and 48,681,489 shares of Class B common stock issued and outstanding. Holders of our Class A and Class B common stock have identical rights, except that holders of our Class A common stock are entitled to one vote per share and holders of our Class B common stock are entitled to ten votes per share. Shares of Class B common stock can be converted to shares of Class A common stock at any time at the option of the stockholder and automatically convert upon sale or transfer, except for certain transfers specified in our amended and restated certificate of incorporation. Stock Incentive Plans 2005 Stock Plan. In January 2005, our stockholders approved our 2005 Stock Plan, which our Board of Directors adopted in November 2004. The 2005 Stock Plan became effective on February 16, 2005, the day prior to the completion of our initial public offering. Our 2005 Stock Plan, as amended and restated, provides for the ability to grant ISOs, NQs, restricted stock, RSUs, SARs, deferred stock units, performance units, performance bonus awards and performance shares. A total of 29.0 million shares of our Class A common stock is authorized for issuance under the 2005 Stock Plan. For awards granted prior to February 2011, any shares subject to an award with a per share price less than the fair market value of our Class A common stock on the date of grant and any shares subject to an outstanding RSU award will be counted against the authorized share reserve as two shares for every one share subject to the award, and if returned to the 2005 Stock Plan, such shares will be counted as two shares for every one share returned. For those awards granted from February 2011 onward, any shares subject to an award with a per share price less than the fair market value of our Class A common stock on the date of grant and any shares subject to an outstanding RSU award will be counted against the authorized share reserve as 1.6 shares for every one share subject to the award, and if returned to the 2005 Stock Plan, such shares will be counted as 1.6 for every one share returned. Stock Options. Stock options are generally granted at fair market value on the date of grant. Options granted to employees and officers prior to June 2008 generally vest over four years , with equal annual cliff-vesting and expire on the earlier of 10 years after the date of grant or 3 months after termination of service. Options granted to employees and officers from June 2008 onward generally vest over four years, with 25% of the shares subject to the option becoming exercisable on the one-year anniversary of the date of grant and the balance of the shares vesting in equal monthly installments over the following 36 months . These options expire on the earlier of 10 years after the date of grant or 3 months after termination of service. All options granted vest over the requisite service period and upon the exercise of stock options, we issue new shares of Class A common stock under the 2005 Stock Plan. Our 2005 Stock Plan also allows us to grant stock awards which vest based on the satisfaction of specific performance criteria. Performance-Based Stock Options. On December 15, 2015, we granted PSOs to our executive officers with shares of our Class A common stock underlying such options. The contractual term for the PSOs is seven years, with vesting contingent upon market-based performance conditions, representing the achievement of specified Dolby annualized TSR targets at the end of a three-year measurement period ending December 15, 2018. If the minimum conditions are met, the PSOs earned will cliff vest on the third anniversary of the grant date, upon certification of achievement of the performance conditions by our Compensation Committee. Anywhere from 0% to 125% of the shares subject to a PSO may vest based on achievement of the performance conditions at the end of the three-year performance period. During the first quarter of fiscal 2016, we granted 419,623 PSOs to our executive officers. In valuing the PSOs which will be recognized as compensation cost, we used a Monte Carlo valuation model. Aside from the use of an expected term for the PSOs commensurate with their shorter contractual term, the nature of the valuation inputs used in the Monte Carlo valuation model were consistent with those used to value our non-performance based options granted under the 2005 Plan. Compensation cost is being amortized on a straight-line basis over the requisite service period. The following table summarizes information about all stock options issued under our 2005 Stock Plan: Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Life Aggregate Intrinsic Value (1) (in thousands) (in years) (in thousands) Options outstanding at September 25, 2015 8,835 $ 35.85 Grants 2,167 33.15 Exercises (196 ) 28.02 Forfeitures and cancellations (122 ) 40.40 Options outstanding at January 1, 2016 10,684 35.39 7.5 $ 16,417 Options vested and expected to vest at January 1, 2016 9,849 35.31 7.4 16,130 Options exercisable at January 1, 2016 5,188 $ 33.65 6.1 14,117 (1) Aggregate intrinsic value is based on the closing price of our common stock on December 31, 2015 of $33.65 and excludes the impact of options that were not in-the-money. Restricted Stock Units. Beginning in fiscal 2008, we began granting RSUs to certain directors, officers and employees under our 2005 Stock Plan. Awards granted to employees and officers generally vest over four years, with equal annual cliff-vesting. Awards granted to directors prior to November 2010 generally vest over three years, with equal annual cliff-vesting. Awards granted after November 2010 and prior to fiscal 2014 to new directors vest over approximately two years, with 50% vesting per year, while awards granted from November 2010 onward to ongoing directors generally vest over approximately one year. Awards granted to new directors from fiscal 2014 onward vest on the earlier of the first anniversary of the award’s date of grant, or the day immediately preceding the date of the next annual meeting of stockholders that occurs after the award’s date of grant. Our 2005 Stock Plan also allows us to grant RSUs which vest based on the satisfaction of specific performance criteria, although no such awards have been granted as of January 1, 2016 . At each vesting date, the holder of the award is issued shares of our Class A common stock. Compensation expense from these awards is equal to the fair market value of our common stock on the date of grant and is recognized on a straight-line basis over the requisite service period. The following table summarizes information about RSUs issued under our 2005 Stock Plan: Shares Weighted-Average Grant Date Fair Value (in thousands) Non-vested at September 25, 2015 2,830 $ 40.73 Granted 1,133 33.19 Vested (817 ) 36.11 Forfeitures (44 ) 39.60 Non-vested at January 1, 2016 3,102 $ 39.21 Employee Stock Purchase Plan . Our plan allows eligible employees to have up to 10 percent of their eligible compensation withheld and used to purchase Class A common stock, subject to a maximum of $25,000 worth of stock purchased in a calendar year or no more than 1,000 shares in an offering period, whichever is less. An offering period consists of successive six -month purchase periods, with a look back feature to our stock price at the commencement of a one -year offering period. The plan provides for a discount equal to 15 percent of the lower of the closing price of our common stock on the New York Stock Exchange on the first and last day of the offering periods. The plan also includes an automatic reset feature that provides for an offering period to be reset and recommenced to a new lower-priced offering if the offering price of a new offering period is less than that of the immediately preceding offering period. Stock Option Valuation Assumptions We use the Black-Scholes option pricing model to determine the estimated fair value of employee stock options at the date of the grant. The Black-Scholes model includes inputs that require us to make certain estimates and assumptions regarding the expected term of the award, as well as the future risk-free interest rate, and the volatility of our stock price over the expected term of the award. Expected Term. The expected term of an award represents the estimated period of time that options granted will remain outstanding, and is measured from the grant date to the date at which the option is either exercised or canceled. Our determination of the expected term involves an evaluation of historical terms and other factors such as the exercise and termination patterns of our employees who hold options to acquire our common stock, and is based on certain assumptions made regarding the future exercise and termination behavior. Risk-Free Interest Rate. The risk-free interest rate is based on the yield curve of United States Treasury instruments in effect on the date of grant. In determining an estimate for the risk-free interest rate, we use average interest rates based on these instruments’ constant maturities with a term that approximates and corresponds with the expected term of our awards. Expected Stock Price Volatility. The expected volatility represents the estimated volatility in the price of our common stock over a time period that approximates the expected term of the awards, and is determined using a blended combination of historical and implied volatility. Historical volatility is representative of the historical trends in our stock price for periods preceding the measurement date for a period that is commensurate with the expected term. Implied volatility is based upon externally traded option contracts of our common stock. Dividend Yield. The dividend yield is based on our anticipated dividend payout over the expected term of our option awards. Dividend declarations and the establishment of future record and payment dates are subject to the Board of Directors’ continuing determination that the dividend policy is in the best interests of our stockholders. The dividend policy may be changed or canceled at the discretion of the Board of Directors at any time. The weighted-average assumptions used in the determination of the fair value of our stock options were as follows: Fiscal Quarter Ended January 1, December 26, Expected term (in years) 5.24 4.58 Risk-free interest rate 1.8 % 1.5 % Expected stock price volatility 29.8 % 29.7 % Dividend yield 1.4 % 0.9 % Stock-Based Compensation Expense Stock-based compensation expense for equity awards granted to employees is determined by estimating their fair value on the date of grant, and recognizing that value as an expense on a straight-line basis over the requisite service period in which our employees earn the awards. Compensation expense related to these equity awards is recognized net of estimated forfeitures, which reduce the expense recorded in the consolidated statements of operations. The selection of applicable estimated forfeiture rates is based on an evaluation of trends in our historical forfeiture data with consideration for other potential driving factors. If in subsequent periods actual forfeitures significantly differ from our initial estimates, we will revise such estimates accordingly. The following two tables separately present stock-based compensation expense both by award type and classification in our consolidated statements of operations (in thousands): Expense - By Award Type Fiscal Quarter Ended January 1, December 26, Compensation Expense - By Type Stock options $ 6,366 $ 6,283 Restricted stock units 12,076 10,215 Employee stock purchase plan 938 1,344 Total stock-based compensation 19,380 17,842 Benefit from income taxes (5,706 ) (5,151 ) Total stock-based compensation, net of tax $ 13,674 $ 12,691 Expense - By Income Statement Line Item Classification Fiscal Quarter Ended January 1, December 26, Compensation Expense - By Classification Cost of products $ 280 $ 246 Cost of services 129 122 Research and development 5,107 5,274 Sales and marketing 7,710 5,909 General and administrative 6,154 6,291 Total stock-based compensation 19,380 17,842 Benefit from income taxes (5,706 ) (5,151 ) Total stock-based compensation, net of tax $ 13,674 $ 12,691 The tax benefit that we recognize from certain exercises of ISOs and shares issued under our ESPP are excluded from the tables above. This benefit was as follows (in thousands): Fiscal Quarter Ended January 1, December 26, Tax benefit - stock option exercises & shares issued under ESPP $ 95 $ 168 Unrecognized Compensation Expense. At January 1, 2016 , total unrecorded compensation expense associated with employee stock options expected to vest was approximately $45.5 million , which is expected to be recognized over a weighted-average period of 2.7 years. At January 1, 2016 , total unrecorded compensation expense associated with RSUs expected to vest was approximately $90.7 million , which is expected to be recognized over a weighted-average period of 2.9 years. Common Stock Repurchase Program In November 2009, we announced a stock repurchase program ("program"), providing for the repurchase of up to $250.0 million of our Class A common stock. The following table summarizes the initial amount of authorized repurchases as well as additional repurchases approved by our Board of Directors as of January 1, 2016 (in thousands): Authorization Period Authorization Amount Fiscal 2010: November 2009 $ 250,000 Fiscal 2010: July 2010 300,000 Fiscal 2011: July 2011 250,000 Fiscal 2012: February 2012 100,000 Fiscal 2015: October 2014 200,000 Total $ 1,100,000 Stock repurchases under the program may be made through open market transactions, negotiated purchases, or otherwise, at times and in amounts that we consider appropriate. The timing of repurchases and the number of shares repurchased depend upon a variety of factors, including price, regulatory requirements, the rate of dilution from our equity compensation plans and other market conditions. The program does not have a specified expiration date, and can be limited, suspended or terminated at our discretion at any time without prior notice. Shares repurchased under the program will be returned to the status of authorized but unissued shares of Class A common stock. As of January 1, 2016 , the remaining authorization to purchase additional shares is approximately $113.3 million . The following table provides information regarding share repurchase activity under the program during fiscal 2016 : Quarterly Repurchase Activity Shares Repurchased Cost (1) Average Price Paid Per Share (2) (in thousands) Q1 - Quarter ended January 1, 2016 1,140,700 $ 39,449 $ 34.57 Total 1,140,700 $ 39,449 (1) Cost of share repurchases includes the price paid per share and applicable commissions. (2) Average price paid per share excludes commission costs. Dividend In October 2014, our Board of Directors initiated a recurring quarterly dividend program for our stockholders. The following table summarizes the dividend payments made under the program during fiscal 2016 : Fiscal Period Declaration Date Record Date Payment Date Cash Dividend Per Common Share Dividend Payment Fiscal 2016 Q1 - Quarter ended January 1, 2016 January 25, 2016 February 8, 2016 February 17, 2016 $ 0.12 $12.1 million (1) (1) The amount of the dividend payment is estimated based on the number of shares of our Class A and Class B common stock that we estimate will be outstanding as of the Record Date.

Equity [Abstract]
Accumulated Other Comprehensive Income	Accumulated Other Comprehensive Income Other comprehensive income consists of two components: unrealized gains or losses on our available-for-sale marketable investment securities and the gain or loss from foreign currency translation adjustments. Until realized and reported as a component of net income, these comprehensive income items accumulate and are included within accumulated other comprehensive income, a subsection within stockholders’ equity in our consolidated balance sheet.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic EPS is computed by dividing net income attributable to Dolby Laboratories, Inc. by the number of weighted-average shares of Class A and Class B common stock outstanding during the period. Through application of the treasury stock method, diluted EPS is computed in the same manner, except that the number of weighted-average shares outstanding is increased by the number of potentially dilutive shares from employee incentive plans during the period. Potentially dilutive shares represent the hypothetical number of incremental shares issuable under the assumed exercise of outstanding stock options (both vested and non-vested), vesting of outstanding restricted stock units, and shares issued under our employee stock purchase plan. The calculation of dilutive shares outstanding excludes out-of-the-money stock options (i.e., such options' exercise prices were greater than the average market price of our common shares for the period) because their inclusion would have been antidilutive. The following table sets forth the computation of basic and diluted EPS attributable to Dolby Laboratories, Inc. (in thousands, except per share amounts): Fiscal Quarter Ended January 1, December 26, Numerator: Net income attributable to Dolby Laboratories, Inc. $ 30,901 $ 41,357 Denominator: Weighted-average shares outstanding—basic 100,734 102,303 Potential common shares from options to purchase common stock 599 992 Potential common shares from restricted stock units 598 980 Weighted-average shares outstanding—diluted 101,931 104,275 Net income per share attributable to Dolby Laboratories, Inc.: Basic $ 0.31 $ 0.40 Diluted $ 0.30 $ 0.40 Antidilutive awards excluded from calculation: Stock options 5,698 2,683 Restricted stock units 215 159

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our income tax expense, deferred tax assets and liabilities, and reserves for unrecognized tax benefits reflect management's best assessment of estimated current and future taxes to be paid. We are subject to income taxes in both the United States and numerous foreign jurisdictions. Significant judgments and estimates are required in determining the consolidated income tax expense. Unrecognized Tax Benefit As of January 1, 2016 , the total amount of gross unrecognized tax benefits was $59.9 million , of which $49.0 million , if recognized, would reduce our effective tax rate. As of September 25, 2015, the total amount of gross unrecognized tax benefits was $65.2 million , of which $53.0 million , if recognized, would reduce our effective tax rate. The decrease was due to the effective settlement of an IRS tax examination in which the related tax reserve balance was re-classified from long-term income tax payable to current income tax payable. Our net liability for unrecognized tax benefits is classified within other non-current liabilities in our consolidated balance sheets. Withholding Taxes We recognize licensing revenue gross of withholding taxes, which our licensees remit directly to their local tax authorities, and for which we receive a partial foreign tax credit in our income tax provision. The foreign current tax includes this withholding tax expense while the appropriate foreign tax credit benefit is included in current federal and foreign taxes. Withholding taxes were as follows (in thousands): Fiscal Quarter Ended January 1, December 26, Withholding taxes $ 9,782 $ 12,200 Effective Tax Rate Each period, the combination of multiple different factors can impact our effective tax rate. These factors include both recurring items such as tax rates and the relative amount of income earned in foreign jurisdictions, as well as discrete items such as changes to our uncertain tax positions, that may occur in, but are not necessarily consistent between periods. Our effective tax rate decreased from 23% in the first quarter of fiscal 2015 to 21% in the first quarter of fiscal 2016 , which reflects an increased benefit from federal R&D tax credits. The overall decrease in the rate was partially offset by the impact of our settlement of the I.R.S. audit for tax years 2011 and 2012.

Restructuring Charges [Abstract]
Restructuring	11 . Restructuring Restructuring charges recorded in our statement of operations represent costs associated with separate individual restructuring plans implemented in various fiscal periods. The extent of our costs arising as a result of these actions, including fluctuations in related balances between fiscal periods, is based on the nature of activities under the various plans. No restructuring charges were recorded in the fiscal quarter ended January 1, 2016, while our statement of operations for the fiscal quarter ended December 26, 2014 reflects a credit of an immaterial amount coinciding with the completion of activity under our fiscal 2014 restructuring plan. Accruals for restructuring charges are included within accrued liabilities in our consolidated balance sheets while restructuring charges/(credits) are included within restructuring charges/(credits) in our consolidated statements of operations.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	Commitments & Contingencies In the ordinary course of business, we enter into contractual agreements with third parties that include non-cancelable payment obligations, for which we are liable in future periods. These arrangements can include terms binding us to minimum payments and/or penalties if we terminate the agreement for any reason other than an event of default as described by the agreement. The following table presents a summary of our contractual obligations and commitments as of January 1, 2016 (in thousands): Payments Due By Fiscal Period Remainder Of Fiscal Fiscal Fiscal Fiscal Thereafter Total Naming rights $ 3,763 $ 7,619 $ 7,715 $ 7,811 $ 7,909 $ 102,980 $ 137,797 Donation commitments — 6,045 67 67 67 738 6,984 Operating leases 10,127 11,891 10,045 8,056 7,531 30,657 78,307 Purchase obligations 11,394 2,612 — — — — 14,006 Total $ 25,284 $ 28,167 $ 17,827 $ 15,934 $ 15,507 $ 134,375 $ 237,094 Naming Rights. We are party to an agreement for naming rights and related benefits with respect to the Dolby Theatre in Hollywood, California, the location of the Academy Awards®. The term of the agreement is 20 years, over which we will make payments on a semi-annual basis until fiscal 2032. Our payment obligations are conditioned in part on the Academy Awards® being held and broadcast from the Dolby Theatre. Donation Commitments. During fiscal 2014 , we entered into an agreement to contribute and install imaging and audio products to the Museum of the Academy of Motion Picture Arts and Sciences in Los Angeles, California, and provide maintenance services for a fifteen-year period following the Museum's expected opening date in 2017, in exchange for various marketing, branding and publicity benefits. Operating Leases. Operating lease payments represent our commitments for future minimum rent made under non-cancelable leases for office space, including those payable to our principal stockholder and portions attributable to the controlling interests in our wholly owned subsidiaries. Purchase Obligations. Purchase obligations primarily consist of our commitments made under agreements to purchase goods and services for purposes that include IT and telecommunications, marketing and professional services, and manufacturing and other research and development activities. Indemnification Clauses. On a limited basis, our contractual agreements will contain a clause under which we have agreed to provide indemnification to the counterparty, most commonly to licensees in connection with licensing arrangements that include our intellectual property. Additionally, and although not a contractual requirement, we have at times elected to defend our licensees from third party intellectual property infringement claims. Since the terms and conditions of our contractual indemnification clauses do not explicitly specify our obligations, we are unable to reasonably estimate the maximum potential exposure for which we could be liable. Furthermore, we have not historically made any payments in connection with any such obligation and believe there to be a remote likelihood that any potential exposure in future periods would be of a material amount. As a result, no amounts have been accrued in our consolidated financial statements with respect to the contingent aspect of these indemnities.

Business Combinations [Abstract]
Acquisitions	Business Combinations Doremi Technologies, LLC. On October 31, 2014 ("acquisition date"), we completed our acquisition of all outstanding interests of Doremi Technologies, LLC. ("Doremi"), a privately held company, and certain assets related to the business of Doremi from Doremi Labs, Inc. and Highlands Technologies SAS (the "Doremi-related assets") for cash consideration of $98.4 million and up to an additional $20.0 million in contingent considerat ion that may be earned over a four -year period following the closing of the acquisition. Upon acquisition, the fair value of the contingent consideration liability was estimated as $0.7 million and was determined by applying a discounted and probability-weighted approach to potential shipments of specified products over the four-year period. Based on a revision to initial estimates, the fair value of this liability was remeasured to $0.1 million as of September 25, 2015. No further changes to our estimates have since been made, and accordingly the liability of $0.1 million remains included within our consolidated balance sheet as of January 1, 2016 . The following table summarizes the purchase price allocation made to the net tangible and intangible assets acquired (including cash of $8.4 million ) and liabilities assumed based on their acquisition date fair values, with the excess amount recorded as goodwill, which is representative of the expected benefits and synergies from the integration of Doremi technology with ours as well as their assembled workforce.

Loss Contingency, Information about Litigation Matters [Abstract]
Legal Proceedings	Legal Matters In December 2013, the Korean Fair Trade Commission (“KFTC”) initiated a review of the Company under Korean competition law. The KFTC requested information relating to our business practices in Korea and we cooperated during its review. As a result of this review, in July 2015, the KFTC issued an order and we agreed to modify certain terms in our standard licensing agreements going forward without admitting to any liability or wrongdoing. In March 2014, the National Development and Reform Commission of China (“NDRC”) initiated a review of our business practices under the Chinese competition laws, and requested information relating to our business practices in China. In early May 2015, the NDRC confirmed that the matters under review have been resolved on mutually agreeable terms. The implementation of these terms remains ongoing. We are involved in various legal proceedings that occasionally arise in the normal course of business. These can include claims of alleged infringement of intellectual property rights, commercial, employment and other matters. In our opinion, resolution of these proceedings is not expected to have a material adverse impact on our operating results or financial condition. Given the unpredictable nature of legal proceedings, it is possible that an unfavorable resolution of one or more such proceedings could materially affect our future operating results or financial condition in a particular period, including as a result of required changes to our licensing terms, monetary penalties and other potential consequences. However, based on the information known by us as of the date of this filing and the rules and regulations applicable to the preparation of our consolidated financial statements, any such amount is either immaterial, or it is not possible to provide an estimated amount of any such potential loss.

Accounting Policies [Abstract]
Principles Of Consolidation	Principles of Consolidation The unaudited interim condensed consolidated financial statements include the accounts of Dolby Laboratories, Inc. and our wholly owned subsidiaries. In addition, we have consolidated the financial results of jointly owned affiliated companies in which our principal stockholder has a controlling interest. We report these controlling interests as a separate line in our consolidated statements of operations as net income attributable to controlling interest and in our consolidated balance sheets as a controlling interest. We eliminate all intercompany accounts and transactions upon consolidation.
Operating Segments	Operating Segments We operate as a single reporting segment, and thus all required financial segment information is included in our unaudited interim condensed consolidated financial statements. This determination reflects the fact that our CODM, our Chief Executive Officer, evaluates our financial information and resources, and assesses the performance of these resources on a consolidated basis.
Use of Estimates	Use of Estimates The preparation of our financial statements in accordance with GAAP requires management to make certain estimates and assumptions that affect the amounts reported and disclosed in our unaudited interim condensed consolidated financial statements and accompanying notes. Significant items subject to such estimates and assumptions include estimated selling prices for elements sold in ME revenue arrangements; valuation allowances for accounts receivable; carrying values of inventories and certain property, plant, and equipment, goodwill and intangible assets; fair values of investments; accrued liabilities including liabilities for unrecognized tax benefits, deferred income tax assets and liabilities and stock-based compensation. Actual results could differ from our estimates.
Fiscal Year	Fiscal Year Our fiscal year is a 52 or 53 week period ending on the last Friday in September. The fiscal periods presented herein include the 14 week period ended January 1, 2016 and the 13 week period December 26, 2014.
