Accounting Policies [Abstract]
Use of Estimates	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 these estimates.
Reclassification	Certain prior period balances have been reclassified to conform to the current period’s presentation. These reclassifications did not have a material impact on previously reported financial statements.
Recent Accounting Pronouncements	In August 2020, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2020-06, Accounting for Convertible Instruments in an Entity’s Own Equity, which simplifies the accounting for convertible instruments and contracts on an entity’s own equity. Among other changes, ASU No. 2020-06 removes from U.S. GAAP the liability and equity separation model for convertible instruments with a cash conversion feature, and as a result, after adoption, entities will no longer separately present in equity an embedded conversion feature for such debt. Similarly, the embedded conversion feature will no longer be amortized into income as interest expense over the life of the instrument. Instead, entities will account for a convertible debt instrument wholly as debt unless (1) a convertible instrument contains features that require bifurcation as a derivative under ASC Topic 815, Derivatives and Hedging, or (2) a convertible debt instrument was issued at a substantial premium. This ASU is effective for interim and annual periods beginning after December 15, 2021, with early adoption permitted after December 15, 2020 and can be adopted either on a modified retrospective or full retrospective basis. The Company is evaluating the impact, timing and method of adoption of this ASU. Upon adoption of this ASU, the Company expects to recombine the equity conversion component of its convertible notes, which was initially separated and recorded in equity, and remove the remaining debt discounts recorded for this previous separation. Adoption of this ASU will also result in the elimination of a portion of non-cash interest expense related to amortization of debt discount. Additionally, ASU No. 2020-06 requires the application of the if-converted method to calculate the impact of convertible instruments on diluted earnings per share, which would result in an increase in the number of shares for calculating diluted earnings per share by approximately 19.9 million shares.
Segment Information	Operating segments are defined as components of an enterprise that engage in business activities for which separate financial information is available and evaluated 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 Company’s internal reporting structure, the Company consists of two operating segments: Video and Cable Access. The operating segments were determined based on the nature of the products offered.
Indemnification	The Company is obligated to indemnify its officers and the members of its Board of Directors pursuant to its bylaws and contractual indemnity agreements. The Company also indemnifies some of its suppliers and most of its customers for specified intellectual property matters pursuant to certain contractual arrangements, subject to certain limitations. The scope of these indemnities varies, but, in some instances, includes indemnification for damages and expenses (including reasonable attorneys’ fees).
