Nature of Business and Basis of Presentation	'
	1. Nature of Business and Basis of Presentation
	The Company
	SeaChange International, Inc. and its subsidiaries (“SeaChange”, “we”, or the “Company”) is an industry leader in the delivery of multi-screen video. Our products and services facilitate the aggregation, licensing, management and distribution of video (primarily movies and television programming) and television advertising content to cable television system operators and telecommunications companies.
	Basis of Presentation
	The accompanying unaudited consolidated financial statements include the accounts of SeaChange International, Inc. and its subsidiaries (“SeaChange” or the “Company”) and are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial reports as well as rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany transactions and balances have been eliminated. Certain information and footnote disclosures normally included in financial statements prepared under U.S. GAAP have been condensed or omitted pursuant to such regulations. However, we believe that the disclosures are adequate to make the information presented not misleading. In the opinion of management, the accompanying financial statements include all adjustments necessary to present a fair presentation of the consolidated financial statements for the periods shown. These consolidated financial statements should be read in conjunction with our most recently audited financial statements and related footnotes included in our Annual Report on Form 10-K (“Form 10-K”) as filed with the SEC. The balance sheet data as of January 31, 2014 that is included in this Form 10-Q was derived from our audited financial statements. We have reclassified certain fiscal 2014 data to conform to our fiscal 2015 presentation.
	The preparation of these financial statements in conformity with U.S. GAAP, requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. Interim results are not necessarily indicative of the operating results for the full fiscal year or any future periods and actual results may differ from our estimates. During the three and six months ended July 31, 2014, there have been no material changes to our significant accounting policies that were described in our fiscal 2014 Form 10-K, as filed with the SEC.

Fair Value Measurements	'
	2. Fair Value Measurements
	Definition and Hierarchy
	The applicable accounting guidance defines fair value as 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 on the measurement date. The guidance establishes a framework for measuring fair value and expands required disclosure about the fair value measurements of assets and liabilities. This guidance requires us to classify and disclose assets and liabilities measured at fair value on a recurring basis, as well as fair value measurements of assets and liabilities measured on a non-recurring basis in periods subsequent to initial measurement, in a fair value hierarchy.
	The fair value hierarchy is broken down into three levels based on the reliability of inputs and requires an entity to maximize the use of observable inputs, where available. The following summarizes the three levels of inputs required, as well as the assets and liabilities that we value using those levels of inputs:
		•		Level 1—Observable inputs that reflect quoted prices for identical assets or liabilities in active markets.
		•		Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not very active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
		•		Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	Valuation Techniques
	When developing fair value estimates for certain financial assets and liabilities, we maximize the use of observable inputs and minimize the use of unobservable inputs. When available, we use quoted market prices, market comparables and discounted cash flow projections. Financial instruments include money market funds, U.S. treasury notes or bonds and U.S. government agency bonds.
	In general, and where applicable, we use quoted prices in active markets for identical assets or liabilities to determine fair value. If quoted prices in active markets for identical assets or liabilities are not available to determine fair value, then we use quoted prices for similar assets and liabilities or inputs that are observable either directly or indirectly. In periods of market inactivity, the observability of prices and inputs may be reduced for certain instruments. This condition could cause an instrument to be reclassified from Level 1 to Level 2 or from Level 2 to Level 3.
	The following tables set forth our financial assets and liabilities that were accounted for at fair value on a recurring basis as of July 31, 2014 and January 31, 2014:
					Fair Value at July 31, 2014 Using

	Available-For-Sale Securities
	We determine the appropriate classification of debt investment securities at the time of purchase and re-evaluate such designation as of each balance sheet date. Our investment portfolio consists of money market funds, U.S. treasury notes and bonds, and U.S. government agency notes and bonds as of July 31, 2014 and January 31, 2014. All highly liquid investments with an original maturity of three months or less when purchased are considered to be cash equivalents. All cash equivalents are carried at cost, which approximates fair value. Our marketable securities are classified as available-for-sale and are reported at fair value with unrealized gains and losses, net of tax, reported in stockholders’ equity as a component of accumulated other comprehensive loss. The amortization of premiums and accretion of discounts to maturity are computed under the effective interest method and are included in other (expenses) income, net, in our consolidated statements of operations and comprehensive (loss) income. Interest on securities is recorded as earned and is also included in other (expenses) income, net. Any realized gains or losses would be shown in the accompanying consolidated statements of operations and comprehensive (loss) income in other (expenses) income, net. We provide fair value measurement disclosures of available-for-sale securities in accordance with one of three levels of fair value measurement mentioned above.
	The following is a summary of available-for-sale securities, including the cost basis, aggregate fair value and gross unrealized gains and losses, for cash equivalents, short- and long-term marketable securities portfolio as of July 31, 2014 and January 31, 2014:

	Indemnification and Warranties
	We provide indemnification, to the extent permitted by law, to our officers, directors, employees and agents for liabilities arising from certain events or occurrences while the officer, director, employee or agent is, or was, serving at our request in such capacity. With respect to acquisitions, we provide indemnification to, or assume indemnification obligations for, the current and former directors, officers and employees of the acquired companies in accordance with the acquired companies’ bylaws and charters. As a matter of practice, we have maintained directors’ and officers’ liability insurance including coverage for directors and officers of acquired companies.
	We enter into agreements in the ordinary course of business with customers, resellers, distributors, integrators and suppliers. Most of these agreements require us to defend and/or indemnify the other party against intellectual property infringement claims brought by a third party with respect to our products. From time to time, we also indemnify customers and business partners for damages, losses and liabilities they may suffer or incur relating to personal injury, personal property damage, product liability, and environmental claims relating to the use of our products and services or resulting from the acts or omissions of us, our employees, authorized agents or subcontractors. From time to time we have received requests from customers for indemnification of patent litigation claims. Management cannot reasonably estimate any potential losses, but these claims could result in material liability for us. There are no current pending legal proceedings, in the opinion of management that would have a material adverse effect on our financial position, results from operations and cash flows. There is no assurance that future legal proceedings arising from ordinary course of business or otherwise, will have a material adverse effect on our financial position, results from operations or cash flows.
	We warrant that our products, including software products, will substantially perform in accordance with our standard published specifications in effect at the time of delivery. In addition, we provide maintenance support to our customers and therefore allocate a portion of the product purchase price to the initial warranty period and recognize revenue on a straight line basis over that warranty period related to both the warranty obligation and the maintenance support agreement. When we receive revenue for extended warranties beyond the standard duration, it is deferred and recognized on a straight line basis over the contract period. Related costs are expensed as incurred.
	Revolving Line of Credit/Demand Note Payable
	We have a Demand Promissory Note in the aggregate amount of $20.0 million (the “Line of Credit”) with JP Morgan Chase Bank, N.A. (“JP Morgan”). Borrowings under the Line of Credit will be used to finance working capital needs and for general corporate purposes. The Line of Credit expires on November 27, 2014. We currently do not have any borrowings nor do we have any financial covenants under this line.

	7. Stock Repurchase Program
	On September 4, 2013, our Board of Directors authorized the repurchase of up to $25.0 million of our common stock through a share repurchase program which would have terminated on January 31, 2015. On May 31, 2014, this program was amended to increase the authorized repurchase amount to $40.0 million and extend the termination date to April 30, 2015. Under the program, we are authorized to repurchase shares through Rule 10b5-1 plans, open market purchases, privately negotiated transactions, block purchases or otherwise in accordance with applicable federal securities laws, including Rule 10b-18 of the Securities Exchange Act of 1934. This share repurchase program does not obligate us to acquire any specific number of shares and may be suspended or discontinued at any time. All repurchases are expected to be funded from our current cash and investment balances. The timing and amount of shares to be repurchased will be based on market conditions and other factors, including price, corporate and regulatory requirements, and alternative investment opportunities. Any shares repurchased by us under the share repurchase program will reduce the number of shares outstanding. Pursuant to the share repurchase program, we executed a Rule 10b5-1 plan in June 2014 to repurchase shares. During the three months ended July 31, 2014, we used $2.0 million of cash in connection with the repurchase of 252,120 shares of our common stock (an average price of $7.93 per share). During the six months ended July 31, 2014, we used $5.5 million of cash in connection with the repurchase of 591,520 shares of our common stock (an average price of $9.31 per share). As of July 31, 2014, $34.5 million remained available under the existing share repurchase authorization.

	2011 Compensation and Incentive Plan
	In July 2011, our stockholders approved the adoption of our 2011 Compensation and Incentive Plan (the “2011 Plan”). Under the 2011 Plan, as amended in July 2013, the number of authorized shares of common stock is equal to 5,300,000 shares plus the number of shares that expired, terminated, surrendered or forfeited awards subsequent to July 20, 2011 under the Amended and Restated 2005 Equity Compensation and Incentive Plan (the “2005 Plan”). Following approval of the 2011 Plan, we terminated the 2005 Plan. The 2011 Plan provides for the grant of incentive stock options, nonqualified stock options, restricted stock, restricted stock units (“RSUs”), and other equity based non-stock option awards as determined by the plan administrator by officers, employees, consultants, and directors of the Company.
	We may satisfy awards upon the exercise of stock options or vesting of RSUs with newly issued shares or treasury shares. The Board of Directors is responsible for the administration of the 2011 Plan and determining the terms of each award, award exercise price, the number of shares for which each award is granted and the rate at which each award vests. In certain instances the Board of Directors may elect to modify the terms of an award.
	Option awards may be granted to employees at an exercise price per share of not less than 100% of the fair market value per common share on the date of the grant. RSUs and other equity-based non-stock option awards may be granted to any officer, employee, director, or consultant at a purchase price per share as determined by the Board of Directors. Awards granted under the 2011 Plan generally vest over three years and expire seven years from the date of the grant.

	We recorded an income tax provision from continuing operations of $0.2 million for the three months ended July 31, 2014 and an income tax benefit of $0.1 million for the six month period. The benefit for the year is attributable to foreign losses that can be benefitted.
	Our effective tax rate in fiscal 2015 and in future periods may fluctuate on a quarterly basis as a result of changes in the valuation of our deferred tax assets, changes in actual results versus our estimates, or changes in tax laws, regulations, accounting principles, or interpretations thereof. We regularly review our tax positions in each significant taxing jurisdiction in the process of evaluating our unrecognized tax benefits. We make adjustments to our unrecognized tax benefits when: i) facts and circumstance regarding a tax position change, causing a change in management’s judgment regarding that tax position; ii) a tax position is effectively settled with a tax authority; and/or iii) the statute of limitations expires regarding a tax position.
	We file income tax returns in U.S. federal jurisdiction, various state jurisdictions, and various foreign jurisdictions. We are no longer subject to U.S. federal examinations before fiscal 2010. However, the taxing authorities still have the ability to review the propriety of certain tax attributes created in closed years if such tax attributes are utilized in an open tax year. Presently, we are undergoing an IRS audit for the fiscal years 2010 through 2012.

Net Loss Per Share	'
	12. Net Loss Per Share
	Net loss per share is presented in accordance with authoritative guidance which requires the presentation of “basic” and “diluted” earnings per share. Basic net loss per share is computed by dividing earnings available to common shareholders by the weighted-average shares of common stock outstanding during the period. For the purposes of calculating diluted earnings per share, the denominator includes both the weighted average number of shares of common stock outstanding during the period and the weighted average number of shares of potential dilutive shares of common stock, such as stock options and RSUs, calculated using the treasury stock method. Basic and diluted net loss per share was the same for the periods presented as the impact of potential dilutive shares outstanding was anti-dilutive.
	The following table sets forth our computation of basic and diluted net loss per common share (amounts in thousands, except per share amounts):

	We consider the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations.
	Recent Accounting Guidance Not Yet Effective
	Accounting For Share-Based Payments- Performance Target Could Be Achieved after the Requisite Service Period
	In June 2014, the FASB issued ASU No. 2014-12, “Compensation—Stock Compensation (Topic 718)—Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” ASU 2014-12 requires that a performance target which affects vesting and that could be achieved after the requisite service period be treated as a performance condition by applying existing guidance in Topic 718 as it relates to awards with performance conditions. The amendment also specifies the period over which compensation costs should be recognized. The amendment is effective for annual reporting periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2014-12 on our consolidated financial statements.
	Revenue from Contracts with Customers
	In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and the International Financial Reporting Standards. This guidance supersedes previously issued guidance on revenue recognition and gives a five step process an entity should follow so that the entity recognizes revenue that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This new guidance will be effective for our fiscal 2018 reporting period and must be applied either retrospectively during each prior reporting period presented or retrospectively with the cumulative effect of initially applying this guidance recognized at the date of the initial application. Early adoption is not permitted. We are currently evaluating the impact of the adoption of this ASU on our consolidated financial statements.
	Reporting Discontinued Operations and Disposals of Components of an Entity
	In April 2014, the FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) – Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity,” which changes the criteria for reporting discontinued operations while enhancing disclosures in this area. The amended guidance requires that a disposal representing a strategic shift that has (or will have) a major effect on an entity’s financial results or a business activity classified as held for sale should be reported as discontinued operations. This guidance also expands the disclosures required when an entity reports a discontinued operation or when it disposes of or classifies as held for sale an individually significant component that does not meet the definition of a discontinued operation. This new guidance will be effective prospectively on disposals (or classifications of held for sale) of components of an entity that occur within our fiscal year beginning on February 1, 2015. Early adoption is permitted but only for disposals (or classification as held for sale) that have not been reported in financial statements previously issued or available for issuance. We are currently evaluating the impact of the adoption of this ASU on our consolidated financial statements.

	Basis of Presentation
	The accompanying unaudited consolidated financial statements include the accounts of SeaChange International, Inc. and its subsidiaries (“SeaChange” or the “Company”) and are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial reports as well as rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany transactions and balances have been eliminated. Certain information and footnote disclosures normally included in financial statements prepared under U.S. GAAP have been condensed or omitted pursuant to such regulations. However, we believe that the disclosures are adequate to make the information presented not misleading. In the opinion of management, the accompanying financial statements include all adjustments necessary to present a fair presentation of the consolidated financial statements for the periods shown. These consolidated financial statements should be read in conjunction with our most recently audited financial statements and related footnotes included in our Annual Report on Form 10-K (“Form 10-K”) as filed with the SEC. The balance sheet data as of January 31, 2014 that is included in this Form 10-Q was derived from our audited financial statements. We have reclassified certain fiscal 2014 data to conform to our fiscal 2015 presentation.
Fair Value Measurements	'
	Fair Value Measurements
	Definition and Hierarchy
	The applicable accounting guidance defines fair value as 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 on the measurement date. The guidance establishes a framework for measuring fair value and expands required disclosure about the fair value measurements of assets and liabilities. This guidance requires us to classify and disclose assets and liabilities measured at fair value on a recurring basis, as well as fair value measurements of assets and liabilities measured on a non-recurring basis in periods subsequent to initial measurement, in a fair value hierarchy.
	The fair value hierarchy is broken down into three levels based on the reliability of inputs and requires an entity to maximize the use of observable inputs, where available. The following summarizes the three levels of inputs required, as well as the assets and liabilities that we value using those levels of inputs:
		•	Level 1—Observable inputs that reflect quoted prices for identical assets or liabilities in active markets.
		•	Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not very active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
		•	Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	Valuation Techniques
	When developing fair value estimates for certain financial assets and liabilities, we maximize the use of observable inputs and minimize the use of unobservable inputs. When available, we use quoted market prices, market comparables and discounted cash flow projections. Financial instruments include money market funds, U.S. treasury notes or bonds and U.S. government agency bonds.
	In general, and where applicable, we use quoted prices in active markets for identical assets or liabilities to determine fair value. If quoted prices in active markets for identical assets or liabilities are not available to determine fair value, then we use quoted prices for similar assets and liabilities or inputs that are observable either directly or indirectly. In periods of market inactivity, the observability of prices and inputs may be reduced for certain instruments. This condition could cause an instrument to be reclassified from Level 1 to Level 2 or from Level 2 to Level 3.
