Broadcom Combines DOCSIS 3.0 Cable Modem, VoIP and UltraHD STB

Broadcom introduced a hybrid cable gateway set-top box solution combining DOCSIS 3.0 and Gigabit wireless gateway functionality with HEVC video decoders and a quad video transcoder onto a single piece of silicon. Broadcom integrates the functionality previously required by five different devices.

The new device features a dual-core CPU that supports multiple applications running simultaneously in secure memory containers for better security.  It also integrates a quad transcoder to enable "TV everywhere" video services on four wireless mobile devices simultaneously, including smartphones and tablets.  In addition, by integrating H.265/HEVC video decoder technology, Broadcom's new cable hybrid gateway device transmits high quality video at one-fourth the bandwidth required by MPEG-2 HD, enabling the delivery of UltraHD content using similar bandwidth as today's MPEG-2 1080p HD.  It also integrates Full Band Capture tuner, which enables the 32 demodulators to be used for DVB-C/QAM and DOCSIS simultaneously, with complete channel flexibility up to 1GHz.

"Broadcom's new BCM7145 is a giant step forward in set-top box gateway chip design and is a key enabler for an all-IP cable platform," said John Gleiter, Broadcom Vice President of Set-top Box Marketing, Broadband Communications Group. "We have engineered a new solution that builds on Broadcom's unmatched, broad-ranged expertise in set-top box devices and our breadth of broadband, MoCA 2.0, Gigabit routing and leading 5G 802.11ac wireless technologies. As a result, the BCM7145 is a breakthrough that delivers what operators want to compete in their markets."
