Broadcom Corp. has uncloaked its chipsets that the company said enable operators and OEMs to speed introduction of UltraHD subscriber hardware and content. The firm stated that the set-top box (STB) devices for satellite, cable and IP integrate support for the advanced high-efficiency video codec (HEVC) standard H.265 that will allow existing high-speed data networks to better use the higher throughput required by UltraHD content.

Broadcom's family of devices also provides OEMs and operators more options for end-point delivery of UltraHD/4k content. The HEVC chip offerings have been architected to support UltraHD/4k up to Main10 profile and up to 60fps, and are designed to rapidly incorporate the latest HDMI 2.0 digital TV interface standard.

By leveraging Broadcom's Trellis STB multi-application software framework with secure hardware sandboxing, platforms based on the devices can facilitate rapid integration of new services through intelligent system partitioning and management.

Broadcom's series of SoCs includes the BCM7251 for multi-HD/UltraHD IP STBs and the BCM7366 with a direct broadcast satellite Full Band Capture front-end receiver, as well as two corresponding MoCA 2.0-enabled STB SoCs for cable and satellite video gateways, the BCM7439 and BCM7376.

The BCM7438 is also offered as an HEVC MoCA 2.0 companion IP client solution for MoCA 2.0 video gateways. When combined with Broadcom's previously announced flagship UltraHD SoC, the BCM7445, this series of 28nm process technology chips spans a full range of device capabilities, from a quad-core ARMv7 Brahma15-powered transcoding gateway to dual-core MoCA clients.

With Broadcom's complete portfolio of HEVC-enabled devices, operators can now substantially cut the bandwidth required for video transmission, offer additional channels on IP, cable or satellite networks, and deliver these services to more locations throughout the home on managed or unmanaged devices.

Service providers with limited broadband capacity, such as telecom companies deploying video over ADSL, or over-the-top providers, may also choose to leverage the higher bandwidth efficiency of the technology to expand their video subscriber footprint by deploying HEVC enabled STB gateways and/or clients.

Featuring high-performance dual-core Brahma15 10000 DMIPs ARMv7 processors, 2180p60 or dual 1080p60 decode and transcode capabilities, Broadcom's portfolio of HEVC chipsets also integrate high-performance connectivity peripherals such as USB 3.0, PCIe, Gigabit Ethernet and MoCA 2.0, noted the company.

The BCM7251 and BCM7439 also incorporate a feature called Dual Display that enables presentation of two simultaneous video channels from the same STB via independent HDMI outputs and remote control devices.
