Broadcom Announces Next Gen STB Chip

Broadcom announced its next gen system-on-a-chip (SoC) solution for cable, satellite and IP set-top boxes (STBs). The new SoC builds on Broadcom's portfolio of HD video compression solutions by utilizing 65 nanometer process technology to significantly reduce bill of materials (BOM) costs and enable higher levels of integration and system performance versus currently available solutions.

The new BCM7405 digital video/audio chip supports the latest in interactive features, a range of video compression standards (i.e. VC-1, WMV9, H.263-H.264, MPEG-4, DIVX) and offers support for digital rights management solutions, including Microsoft DRM10, Secure Video Processor (SVP) technology (a joint venture between NDS and STMicroelectronics) and Marlin JDA (a joint development association formed by Intertrust Technologies, Matsushita Electric Industrial (Panasonic), Royal Philips Electronics, Samsung Electronics and Sony Corporation). It provides a 1000 DMIPS dual-core MIPS processor for multi-stream HD networking capabilities, dual SATA-II interfaces and support for digital rights management solution. Additional key features include:

  • HD+SD Simultaneous Decode

  • Very high performance graphics scaling, blitting and blending

  • An extensive set of 65nm analog cores including dual SATA-II ports, Fast Ethernet PHY, triple USB 2.0 ports, HDMI 1.3, integrated video and audio digital-to-analog converters, an RF modulator and a UHF remote control receiver

  • PC client usage modes to support PC-oriented content viewing on televisions

  • A memory-to-memory DMA security module may be programmed for supporting AES/1DES/3DES/CSS/CPRM/CPPM/DTCP copy protection algorithms/standards

  • Standby modes that offer equipment vendors significant flexibility in configuring various low-power standby modes of operation (becoming a more important factor in set-top box design)

  • An integrated and highly developed, security processor with device
    personalization that provides real-time encryption and decryption for
    all content, home network and TV interfaces

  • Up to 1 GB system memory support, using the latest generation of low-cost DDR2 technology, at up to 800 MHz transfer rates

  • Double data rate Media Independent Interface (MII) for support of home networking chipsets
