Broadcom hits set-top triple play
Broadcom covered all of the TV bases with the introduction of advanced set-top box chips for cable, for satellite and for IPTV systems that run Microsoft’s Mediaroom.
All of Broadcom’s new chips are for set-top boxes that pay-TV providers will use to lower the cost of propagating advanced new services, including whole-home DVR and converged services. Broadcom’s systems-on-chips (SoCs) tightly integrate many of the elements necessary to support the distribution of HD video and other content throughout viewers’ homes.
For cable set-tops, Broadcom has two new SoCs, both integrating dual 866 MHz tuners, a DOCSIS/EuroDOCSIS modem and 3-D graphics processing. The BCM7019 and BCM7025 both also include software support for applications that use Multimedia Home Platform (MHP), Open TV, NDS CDI, SeaChange TV Navigator, Adobe Flash Platform for the Digital Home, Digital Living Network Alliance (DLNA), RVU Remote User Interface (RUI) and PacketCable VoIP.
One of the major differences between the two cable chips is that the 7025 also includes an integrated Multimedia over Coax Alliance (MoCA) 1.1 interface, which enables the ability of subscribers to access, store and share a wide array of digital media content, including HDTV programs, video-on-demand, DVR recordings, Internet content, video, music, photos and VoIP.
The SoCs also integrate dynamic power management controllers capable of managing and shutting down unused system components in real time. Both chips offer support for Energy Star and are European Code of Conduct-compliant.
Both cable STB SoC solutions deliver downstream data rates of up to 200 Mbps, enabling MSOs to deploy downstream channel bonding functionality immediately, without delays or costly upgrades to their CMTS infrastructure, Broadcom said.
Both of the cable set-top box SoC solutions are available to sample. Pricing is available upon request.
For the IPTV segment, Broadcom said it has completed the integration of the Microsoft Mediaroom client in its new BCM7405.
The new IPTV chip, of course, supports existing Mediaroom features, such as instant channel change, HD VOD, 'DVR anywhere' and multi-view, but the 7045 also supports interactive TV applications based on the new Mediaroom Presentation Framework, which enables the integration of traditional video channels with content and information sourced from the Internet.
"Broadcom's completion of Mediaroom client integration represents a significant milestone for the expansion of the Microsoft Mediaroom ecosystem by providing our service provider customers and set-top box OEM partners additional choice in silicon," said Steve Koepp, senior manager of business development for the TV, video and music business at Microsoft. "With Broadcom's high-performance chipset support, we are together driving the transition to a more connected and personal TV entertainment experience in the home."
For the satellite market, Broadcom announced two new single-chip, multi-format HD STB chips.
Functionality will be similar to the cable market SoCs. The satellite STB silicon will support the distribution throughout subscribers’ homes of HDTV programs, VOD, multi-room DVR programming, Internet content, user-generated video, music, photos and VoIP.
The chips integrate support for DLNA Interoperability Guidelines, a 3-D graphics engine for an advanced user interface, support for the MHP to deliver interactive TV applications, the Adobe Flash Platform, MoCA 1.1 and the RVU Alliance's RUI.
Both the 7340 and 7342 chips support multiple worldwide formats, including the DVB-S2, DVB-S and 8PSK standards, with backwards compatibility to the DVB-S standard. Both feature dynamic power management controllers.
The 7340 integrates a single tuner/demodulator and uses an AVC decoder that supports multiple video formats and dynamic power management capabilities. It supports several TV output interfaces on-chip, including HDMI, baseband composite, component or S-Video, and it utilizes a high-definition video encoder (with copy protection) that supports NTSC, PAL and SECAM, with simultaneous standard-definition output integrated on-chip.
The 7342 adds a second tuner to add DVR watch and record capabilities. These chips, too, are sampling. Again, pricing is available upon request, Broadcom said.
