Silicon specialist Broadcom has announced a reference platform for operators in emerging markets to enable them to more cost-effectively deploy two-way set-top box (STB) solutions with high definition (HD) and DOCSIS 2.0. The Broadcom chipset builds on the BCM7019 HD cable system-on-a-chip (SoC).
"Our new HD DOCSIS 2.0 set-top box chipset enables cable operators to leverage their broadband network to deploy higher revenue-generating two-way HD services that compete effectively with satellite and IPTV video providers," said John Gleiter, Broadcom's vice president of cable broadband in the broadband communications group. "Broadcom's new offering brings unprecedented performance and features previously unobtainable in low-cost HD DOCSIS 2.0 STBs."
Broadcom solution addresses this need with a dual-chip design that combines the BCM3308 with the BCM7584. The BCM3308 is a single-chip DOCSIS 2.0 cable modem device.
Broadcom has shipped more than 150 million of its DOCSIS 2.0 SoCs to date. The BCM7584 is the first low-cost HD digital cable STB SoC to integrate Full-Band Capture technology and IP video server technology, which enables the BCM7584's four demodulators to simultaneously access broadcast video and tune DOCSIS, with complete channel flexibility up to 1GHz. Full Band Capture technology also enables advanced remote cable diagnostics, which can mitigate physical customer service calls and save operator substantial service call expenses.
In addition to Full Band Capture, the Broadcom set-top box offering features a 3D graphics processing unit to support advanced user interfaces using HTML5; advanced diagnostics with spectrum analyser, and FastRTV, Broadcom's solution that improves channel change times.
To further enable the rapid development and deployment of the new HD DOCSIS 2.0 STB solution, Broadcom offers a complete single-board reference design with certified DOCSIS 2.0 software and Nexus-Trellis STB software. Broadcom's Nexus-Trellis STB software supports many popular middleware solutions, including the new Open Source-based Reference Development Kit (RDK), to enable rapid porting and software development from BCM7019-based designs. Nexus-Trellis is complemented by a large set of open application libraries supporting popular extensions like DLNA, Miracast, OpenGL, DirectFB and Gstreamer.
