Thanks, Patrick, and thank you all for joining us today. Before I discuss our quarterly results and outlook, I'd like to remind everyone that the financial results I'll be referring to are provided on a non-GAAP basis. As David mentioned earlier, our Q1 press release and earnings presentation includes reconciliations of non-GAAP financial measures to GAAP that are discussed on this call. Both of these are available on our website. For the first quarter of 2022, we delivered solid financial results that were near or above the top of our guidance ranges. These results demonstrate the strength of our businesses, which continue to perform well despite challenges related to the war in Ukraine, the pandemic and our supply chain. Before I run through our quarterly financials in more detail, I brief please review key highlights here on Slide 7. We reported record first quarter revenue of $147.4 million, along with solid EPS of $0.08. The considerable business momentum we saw in 2021 continued in the first quarter of 2022, with bookings of $205.5 million and a book-to-bill ratio of 1.4%. This drove another record backlog and deferred revenue position at quarter end of $497.3 million. Considering the strong first quarter performance and the positive market and competitive trends mentioned by Patrick, we are raising our full-year revenue, adjusted EBITDA and EPS guidance. Now let's review our first quarter financials in more detail. Turning to Slide 8. As I just mentioned, total company Q1 revenue was $147.4 million, up 32.1% year-over-year and down 5.4% sequentially from a seasonally strong Q4. Looking first at our Cable Access business segment. Revenue for the quarter was $81.6 million, up 97.8% year-over-year and 17% sequentially, reflecting both the continued ramp-up of existing customers and new customer wins, including some early success we are seeing with our fiber-to-the-home application. In our Video segment, we reported total Q1 revenue of $65.8 million, down 6.4% year-over-year, of which SaaS revenues were $6.7 million, up 75.3% year-over-year. This modest decline was primarily due to timing of a few broadcast projects and the impact of ceasing sales in Russia. Later on, I will share more details on the anticipated impact on our video business of season sales in Russia. We had three customers representing greater than 10% of total revenue during the quarter. Comcast contributed 31%. Intelsat contributed 13%, and Vodafone contributed 10% of total revenue. Total company gross margin declined by 320 basis points to 47.3% compared to 50.5% in Q4 '21 and by 310 basis points versus Q1 '21. This decline is due to elevated Cable Access segment supply chain-related costs and increased mix of Cable Access segment revenues. Cable Access segment revenue was 55.4% of total company revenue in the quarter. Cable Access gross margin for Q1 '22 was at the high end of our expectations at 38% compared to 40.3% in Q4 '21 and 42.2% in Q1 '21. As anticipated, extraordinary supply chain costs weighed on margins in the first quarter of 2022 relative to the prior year. Also as anticipated, we forecast Cable Access gross margins improving in the second quarter of - as these non-recurring premium costs have now largely flowed through. Video segment gross margin was 58.8% in Q1 '22, up 370 basis points compared to 55.1% in the year-ago period and flat sequentially. The annual improvement reflects an improved software mix within our appliance category. as well as our expanding SaaS business. Moving down the income statement on Slide 9. Q1 '22 operating expenses were $58.4 million compared to $58 million in Q4 '21 and $51.1 million in Q1 '21. The year-over-year increase is primarily due to increased research and development, as well as sales and marketing activities to support the growth of our Cable Access business. Operating expenses represented 39.6% of revenue in Q1 '22 compared to 45.8% of revenue in Q1 '21, demonstrating operating leverage as revenues continue to ramp. Adjusted EBITDA for Q1 '22 was 9.8% of revenue at $14.5 million, comprised of $9.7 million from Cable Access and $4.8 million from Video. This compares to an adjusted EBITDA of $23.8 million, or 15.3% of revenue in Q4 '21 and a year-over-year improvement compared to $9.1 million, or 8.2% of revenue in Q1 '21. This all translated into Q1 '22 EPS of $0.08 per share compared to $0.16 per share in Q4 '21 and $0.04 per share for Q1 '21. We ended the quarter with a diluted weighted average share count of 110.6 million compared to 110.5 million in Q4 '21 and 103.2 million in Q1 '21. The sequential increase is primarily due to the issuance of 1.3 million shares to employees for vested restricted stock units, ESPP purchases and performance-based compensation, offset by a reduction in convertible debt dilution of 0.8 million shares and the dilutive effect of outstanding RSUs and options by 0.4 million shares, both resulting from the decrease in our average stock price in the quarter and by share repurchases of 223,000 shares in the quarter at an average price of $9.18. The year-over-year increase reflects dilution of our convertible debt by 2.5 million shares and the dilutive effect of outstanding RSUs and options by 0.8 million shares, both resulting from an increase in our average stock price during the year, and 4.2 million shares due to the weighted effect of stock issued to employees and ESPP shares. In early February 2022, we announced a stock repurchase program, under which we may repurchase up to $100 million of our outstanding shares of common stock through February 2025. We intend to fund the share repurchases from cash on hand and cash generated from operations. Repurchases under the program may be made from time to time through open market purchases and 10b5-1 trading plan, in accordance with the applicable securities laws. The timing and amount of any repurchases will depend on a variety of factors, including the price of our common stock, market conditions, corporate needs and regulatory requirements. Turning now to the order book. We are pleased to report yet another quarter of strong new bookings. As noted earlier, Q1 bookings were a record $205.5 million compared to $267.3 million in Q4 '21 and up 113.4% from Q1 '21, demonstrating continued robust demand for our solutions. Demand for our Cable Access products was the biggest driver, although Q1 bookings for both segments were up year-over-year in all regions worldwide. The book-to-bill ratio was 1.4% in the quarter compared to 1.7% in Q4 '21 and 0.9% in Q1 '21. On the Cable Access side of the business, we see cable operators buying ahead in anticipation of accelerating 2022 and early 2023 broadband network deployments. Turning to Slide 10. We'll now discuss our liquidity position and balance sheet. We ended Q1 with a cash of $100.7 million compared to $133.4 million at the end of Q4 '21 and $100.8 million in Q1 last year. The $32.7 million sequential cash decrease is primarily comprised of $27.5 million of cash used in working capital, largely in accounts receivable and inventories to support business growth, offset by operating profits of both Cable Access and Video segments, $2.1 million of share repurchases, as I just mentioned, and $2.4 million of cash used in the purchase of fixed assets. Our day sales outstanding at the end of Q1 was 71 days compared to 51 days at the end of Q4 '21 and 69 days in Q1 2021. We expect collections and therefore, accounts receivable to improve in Q2. Our days inventory on hand was 95 days at the end of Q1, compared to 83 days at the end of Q4 '21 and 58 days at the end of Q1 '21, reflecting increasing inventory at the end of the quarter as we prepare for heavy shipments for the rest of the year. We continue to build inventory at higher-than-normal levels to proactively manage the supply chain. At the end of Q1, total backlog and deferred revenue was a record $497.3 million, up 13% sequentially from $441 million at Q4 '21 and up 81% year-over-year from $274.3 million at Q1 '21. This latest backlog in deferred revenue reflects continued growing demand from our large cable customers and increasing video streaming SaaS commitments. Note that more than 80% of our backlog and deferred revenue has customer request dates for shipments of products and providing services within the next 12 months. As mentioned on previous calls, not included in our backlog is additional contractually agreed CableOS business with three of our initial Tier 1 cable customers. At the end of Q1 '22, this incremental amount was approximately $98 million, down from $104 million last quarter and approximately $6 million went through the purchase order process and, therefore, moved into bookings. Taking these CableOS contracts into account, we have total future contracted revenues of approximately $595 million, which continues to provide us with a very solid base as we move ahead into 2022. Now, I'll turn to our revised non-GAAP guidance for 2022, beginning on Slide 11. I will also give brief commentary on key changes from our prior annual guidance we gave in January. For the total company for full-year 2022, we now expect revenue in the range of $585 million to $625 million. The 4% midpoint increase on our previous guidance was driven by an increase in expected cable segment revenue. Gross margin in the range of 49.1% to 50.2%, marginally up 5 basis points at the midpoint versus prior guidance. Gross profit to range from $287 million to $314 million, up 4% at midpoint versus prior guidance. Operating expenses to range from $238 million to $251 million, up 1% at the midpoint of our prior guidance, driven primarily by increased compensation expenses and possible relocation costs related to our contract engineering resources in Ukraine. Adjusted EBITDA to range from $60 million to $74 million. This represents a 16% increase at the midpoint versus prior guidance, driven by the expected increase in cable revenues discussed earlier. EPS to range from $0.34 to $0.45. At the midpoint, this is a 20% increase versus prior guidance. An effective tax rate of 13%, a weighted average diluted share count of approximately 110.8 million, a decline of 1.8 million shares from prior guidance. This was primarily due to reduced dilution on debt, given a softer average stock trading price. Finally, cash at the end of 2022 is expected to come in between $100 million to $110 million, in line with our prior guidance. Turning to Slide 12. I will review our total company outlook for the second quarter of 2022. We expect revenue in the range of $144 million to $154 million; gross margin in the range of 49.3% to 51.2%, gross profit in the range of $71 million to $79 million; operating expenses to range from $61 million to $64 million; adjusted EBITDA to range from $13 million to $18 million, a weighted average diluted share count of approximately 110.8 million, EPS to range from $0.07 to $0.11. At the end of Q2, cash is expected to range from $100 million to $110 million. On Slide 13, I will first give you guidance for both the full year and second quarter of 2022 for our cable segment. For the full-year 2022, based on our progress to date, we expect Cable Access to achieve revenue between $310 million to $338 million, an 8% increase from midpoint of prior guidance, implying full-year revenue growth of 48% at the midpoint. Given our success in navigating capacity constraints through the first four months of the year, we are more comfortable expanding the high end of our outlook. Although to be clear, challenges remain, necessitating a still wide range. Gross margins between 42% to 43.4%. This marginal 40 basis points improvement from prior guidance is due to an expected increase in software and services contributions. Gross profit between $130 million to $147 million, up 9% from prior guidance at the midpoint. Operating expenses between $93 million to $101 million, up 3% from prior guidance at the midpoint. Adjusted EBITDA between $43 million to $51 million, up 22% from prior guidance at the midpoint. For our Cable Access segment, in Q2, we expect revenue in the range of $74 million to $80 million; gross margin in the range of 42% to 44%; gross profit in the range of $31 million to $35 million; operating expenses in the range of $24 million to $26 million, adjusted EBITDA to range from $8 million to $11 million. Now moving on to Slide 14. We will review full year and second quarter 2022 video segment guidance. Currently, we expect revenue in the range of $275 million to $287 million, nearly consistent with prior guidance despite an approximately $6 million negative revenue drag from ceasing sales in Russia. Gross margins in the range of 57% to 58.3%, with a 25 basis point improvement over prior guidance at midpoint. Gross profit in the range of $157 million to $167 million, basically flat with prior guidance at midpoint. Operating expenses in the range of $145 million to $150 million, slightly better than prior guidance at the midpoint. Adjusted EBITDA in the range of $17 million to $23 million, a slight improvement from prior guidance. For Video segment, in Q2, we expect revenue in the range of $70 million to $74 million; gross margins in the range of 57% to 59%; gross profit in the range of $40 million to $44 million, operating expenses in the range of $37 million to $38 million; adjusted EBITDA to range from $4 million to $7 million. In summary, we continue to build on our momentum from 2021 with a strong first quarter and grew our record backlog and deferred revenue balance even further, positioning ourselves well for the balance of 2022 and the trajectory to execute our long-term model. Patrick earlier shared key financial highlights from our updated long-term model for the cable segment. And we are in process of planning another Investor Day in the coming months, during which we will further provide further details on this positive multi-year update. So please stay tuned for additional details on our Investor Day. Thank you, everyone, for your attention today. And now, I'll turn it back to Patrick for final remarks before we open up the call for questions.
