Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States ("U.S. GAAP") and applicable rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2022 (“2022 Form 10-K”). The accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the Company's financial position as of balance sheet dates and its operating results and cash flows for the interim periods presented. Operating results for the three-month period ended March 31, 2023 are not necessarily indicative of the results that may be expected for any subsequent quarter or for the fiscal year ending December 31, 2023. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. The Company’s significant accounting policies are described in Note 2 to its audited Consolidated Financial Statements included in the 2022 Form 10-K. There have been no significant changes to these policies during the three months ended March 31, 2023.

Revenue from Contract with Customer [Abstract]
CONTRACT ASSETS AND DEFERRED REVENUE	CONTRACT ASSETS AND DEFERRED REVENUE Contract assets exist when the Company has satisfied a performance obligation but does not have an unconditional right to consideration (e.g., because the entity first must satisfy another performance obligation in the contract before it is entitled to invoice the customer). Deferred revenue represents the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration (or an amount of consideration is due) from the customer. Contract assets and deferred revenue consisted of the following: As of (in thousands) March 31, 2023 December 31, 2022 Contract assets $ 5,033 $ 5,580 Deferred revenue $ 82,245 $ 80,471 Contract assets and the non-current portion of deferred revenue are reported as components of “Prepaid expenses and other current assets” and “Other non-current liabilities,” respectively, on the condensed consolidated balance sheets. Revenue recognized during the three months ended March 31, 2023 that was included within the deferred revenue balance at January 1, 2023 was $21.2 million. Revenue recognized during the three months ended April 1, 2022, that was included within the deferred revenue balance at January 1, 2022 was $23.5 million. Remaining performance obligations represent contracted revenues that have not yet been recognized and include deferred revenue and unbilled amounts that will be recognized as revenue in the future. The aggregate balance of the Company’s remaining performance obligations as of March 31, 2023 was $631.6 million, majority of which is expected to be recognized as revenue over the next 12 months and the remainder thereafter.

Debt Disclosure [Abstract]
CONVERTIBLE DEBT	CONVERTIBLE DEBT 2.00% Convertible Senior Notes due 2024 (the “2024 Notes”) In September 2019, the Company issued $115.5 million of the 2024 Notes pursuant to an indenture (the “2024 Notes Indenture”), dated September 13, 2019, by and between the Company and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee. The 2024 Notes bear interest at a rate of 2.00% per year, payable semi-annually on March 1 and September 1 of each year, beginning March 1, 2020. The 2024 Notes will mature on September 1, 2024, unless earlier repurchased by the Company, redeemed by the Company or converted pursuant to their terms. The 2024 Notes were initially convertible into cash, shares of the Company’s common stock, or a combination thereof, at the Company’s election, at an initial conversion rate of 115.5001 shares of the Company’s common stock per $1,000 principal amount of the 2024 Notes (which is equivalent to an initial conversion price of approximately $8.66 per share). Pursuant to the supplemental indenture entered into by the Company and the trustee during the fourth quarter of the fiscal year ended December 31, 2021, the Company made an irrevocable election to settle the principal amounts of the 2024 Notes solely with cash and may pay or deliver, as the case may be, any conversion value greater than the principal amount in cash, shares of the Company’s common stock or a combination thereof, at the Company’s election. The conversion rate, and thus the effective conversion price, may be adjusted under certain circumstances, including in connection with conversions made following certain fundamental changes or a notice of redemption and under other circumstances, in each case, as set forth in the 2024 Notes Indenture. The 2024 Notes will be convertible at certain times and upon the occurrence of certain events in the future, in each case, specified in the 2024 Notes Indenture. Further, on or after June 1, 2024, until the close of business on the scheduled trading day immediately preceding the maturity date, holders of the 2024 Notes may convert all or a portion of their 2024 Notes regardless of these conditions. The 2024 Notes remained convertible as of March 31, 2023, as the last reported sale price of the Company’s common stock for at least 20 trading days during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter was greater than or equal to 130% of the conversion price of the 2024 Notes on each applicable trading day. All $114.2 million of the net carrying amount of the 2024 Notes outstanding as of March 31, 2023 was classified as a current liability as of that date. The following table presents the components of the 2024 Notes: As of (in thousands, except for years and percentages) March 31, 2023 December 31, 2022 Liability: Principal amount $ 115,500 $ 115,500 Less: Debt issuance costs, net of amortization (1,296) (1,519) Carrying amount $ 114,204 $ 113,981 The following table presents interest expense recognized for the 2024 Notes: Three Months Ended (in thousands) March 31, 2023 April 1, 2022 Contractual interest expense $ 578 $ 578 Amortization of debt issuance costs 223 217 Total interest expense recognized $ 801 $ 795

Refer to Note 13, “Employee Benefit Plans” of Notes to Consolidated Financial Statements in the 2022 Form 10-K for details pertaining to each plan. As of March 31, 2023, an aggregate of 9,552,296 shares of common stock were reserved for issuance under the 1995 Stock Plan, of which 6,753,467 shares remained available for future grants. As of March 31, 2023, an aggregate of 637,671 shares of common stock were reserved for issuance under the 2002 Director Plan, of which 451,077 shares remained available for future grants. Share Repurchase Program In February 2022, the Board of Directors authorized the Company to repurchase up to $100 million of the Company’s outstanding shares of common stock through February 2025. The Company is authorized to repurchase, from time-to-time, shares of its outstanding common stock through open market purchases and 10b5-1 trading plans, in accordance with applicable rules and regulations, at such time and such prices as management may decide. The program does not obligate the Company to repurchase any specific number of shares and may be discontinued at any time. The actual timing and amount of repurchases are subject to business and market conditions, corporate and regulatory requirements, stock price, acquisition opportunities and other factors. There were no repurchase activities during the three months ended March 31, 2023. As of March 31, 2023, approximately $94.9 million of the share repurchase authorization remained available for repurchases under this program.

The difference between the carrying value and the fair value is primarily due to the spread between the conversion price and the market value of the shares underlying the conversion as of each respective balance sheet date.

SEGMENT INFORMATION	SEGMENT INFORMATIONOperating segments are defined as components of an enterprise that engage in business activities for which separate financial information is available and evaluated regularly by the Company’s Chief Operating Decision Maker (the “CODM”), which for the Company is its Chief Executive Officer, in deciding how to allocate resources and assess performance. Based on the internal reporting structure, the Company consists of two operating segments: Video and Broadband. The operating segments were determined based on the nature of the products offered. The Video segment provides video processing, production and playout solutions and services worldwide to broadcast and media companies, new streaming media companies, broadband operators, and satellite and telecommunications (“telco”) Pay-TV service providers. The Broadband segment provides broadband access solutions and related services to broadband operators globally. A measure of assets by segment is not applicable as segment assets are not included in the discrete financial information provided to the CODM. The following table provides summary financial information by reportable segment: Three Months Ended (in thousands) March 31, 2023 April 1, 2022 Video Revenue $ 57,298 $ 65,842 Gross profit 34,614 38,684 Operating income (loss) (1,426) 3,139 Broadband Revenue $ 100,351 $ 81,597 Gross profit 50,290 31,011 Operating income 20,113 8,139 Total Revenue $ 157,649 $ 147,439 Gross profit 84,904 69,695 Operating income 18,687 11,278 A reconciliation of the Company’s consolidated segment operating income to consolidated income before income taxes is as follows: Three Months Ended (in thousands) March 31, 2023 April 1, 2022 Total consolidated segment operating income $ 18,687 $ 11,278 Unallocated corporate expenses (1) (83) (1,156) Stock-based compensation (7,424) (7,586) Consolidated income from operations 11,180 2,536 Non-operating expense, net (999) (1,371) Income before income taxes $ 10,181 $ 1,165 (1) Together with stock-based compensation, the Company does not allocate restructuring and related charges to the operating income (loss) for each segment because management does not include this information in the measurement of the performance of the operating segments.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal proceedings From time to time, the Company is involved in lawsuits as well as subject to various legal proceedings, claims, threats of litigation, and investigations in the ordinary course of business, including claims of alleged infringement of third-party patents and other intellectual property rights, commercial, employment, and other matters. The Company assesses potential liabilities in connection with each lawsuit and threatened lawsuits and accrues an estimated loss for these loss contingencies if both of the following conditions are met: information available prior to issuance of the financial statements indicates that it is probable that a liability has been incurred at the date of the financial statements and the amount of loss can be reasonably estimated. While certain matters to which the Company is a party specify the damages claimed, such claims may not represent reasonably probable losses. Given the inherent uncertainties of litigation, the ultimate outcome of these matters cannot be predicted at this time, nor can the amount of possible loss or range of loss, if any, be reasonably estimated.
