CES: Broadcom chips power new Comcast STB

US chip vendor Broadcom has issued a slew of releases on the opening day of the Consumer Electronics Show in Las Vegas, including the revelation that it is powering new interactive and personalised multi-screen experiences for Comcast subscribers.

The cable operator has based its new RNG150N set-top boxes on Broadcom’s BCM7125 system-on-a-chip (SoC), which integrate five major STB functions into one device: a full DOCSIS cable modem, MPEG 4 HD decoder, MoCA 1.1 modem, 1GHz tuners and 3D graphics.

The new set-top boxes are already shipping to subscribers and power Comcast whole-home media distribution and 3D user interfaces. Most significantly, they enable Comcast to support IP video streaming, and integrate the X1 user interface with social networking, personalisation and fast searching.

Another major deal won by Broadcom is to provide 5G WiFi technology for use in select digital TVs from Korea’s LG Electronics, enabling consumers to stream and share high-resolution content between mobile devices and smart TVs.

“By adding 5G WiFi to our flagship Smart TV platforms, our customers will experience the fastest, most reliable wireless connectivity yet,” said Sangyeob Lee, LG Electronics Senior Director, TV Product Planning. “Partnering with Broadcom allows us to raise the bar and be the first company to introduce the next generation of WiFi in our Smart TV platforms.

At CES 2013 Broadcom has also unveiled its first Ultra-HD video decoder solution, featuring four 1080p30 real-time transcoders and HEVC compression to deliver 4K (4096×2160) picture resolutions. The BCM7445 chip can also simultaneously deliver four transcoded HD video streams over IP for content on any screen, and high-volume production will start in 2014.

Finally, Broadcom has also announced its first Gigabit MoCA 2.0 single chip solution, designed to extend Gigabit speeds over coax throughout the home for ultra-fast TV and broadband content delivery. The Broadcom BCM6802 MoCA 2.0 SoC is now sampling, but no information was given on when it will start shipping.
