Broadcom launches new chipsets for UltraHD STBs

Broadcom has launched HEVC chipsets that allow operators and OEMs to introduce UltraHD subscriber hardware and content. The chips are designed to support UltraHD/4k up to Main10 profile and up to 60 frames per second and integrate the latest HDMI 2.0 digital TV interface standard. Platforms based on the new devices can allow the integration of new services through intelligent system partitioning and management, according to the company.

Broadcom's new series of systems-on-a-chip (SoCs) includes the BCM7251 for multi-HD/UltraHD IP set-top boxes 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 use with MoCA 2.0 video gateways. When combined with Broadcom's previously announced flagship UltraHD SoC, the BCM7445, this new series of 28nm (nm) process technology chips covers various device capabilities, from a quad-core ARMv7 Brahma15-powered transcoding gateway to dual-core MoCA clients.

With Broadcom's 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 telecommunications 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 set-top box gateways and/or clients.

Featuring dual-core Brahma15 10000 DMIPs ARMv7 processors, 2180p60 or dual 1080p60 decode and transcode capabilities, Broadcom's new portfolio of HEVC chipsets also integrate connectivity peripherals, such as USB 3.0, PCIe, Gigabit Ethernet and MoCA 2.0. Broadcom's latest generation security core is included in all devices offering platform security, content protection and DRM robustness. Support for high speed DDR3 and DDR4 devices is included, as well as dedicated interfaces to a range of Broadcom companion front end cable, DOCSIS, satellite and 802.11ac Wi-Fi devices. The BCM7251 and BCM7439 also incorporate a new feature called Dual Display, which enables presentation of two simultaneous video channels from the same set-top box via independent HDMI outputs and remote control devices.

Broadcom's HEVC chipsets are currently sampling.
