It is a highly integrated, cost-effective design built on the latest generation of Broadcom silicon and software offering low risk and quick time-to-market for the next generation of interactive set-top boxes. interactive services. The triple tuner architecture allows for web browsing, video and Personal Video Recording (PVR) on a separate channel. Time shifting is also simultaneously supported on the channel being viewed. The dual MPEG-2 encoder allows full support of watch and record on 2 analog channels. Also included is support of high definition (HD) PVR. Features also include studio-quality text for presenting standard Windows® fonts on a standard or high definition television and a high-performance 3D graphics engine for applications such as gaming and e-commerce. The core chip set on the BCM93740 includes the BCM3250 QAMLink® Advanced Set-Top Box Single-Chip Front End with DOCSIS™/EuroDOCSIS/DAVIC modems, the BCM7030 Advanced High Definition Video/3D Graphics Subsystem, and a high-performance MIPS R5000™ class processor. The BCM3125 supplies the additional QAM demodulator and upstream burst modulator. The BCM7041 dual MPEG-2 encoder provides the realtime encoding for analog PVR. The BCM3250 is a complete front-end advanced set-top box solution providing dual 256-QAM receivers, an out-of-band QPSK receiver and a QPSK/16-QAM upstream burst modulator. All major physical layer standards are supported allowing set-tops based on the BCM93740 design to be deployed worldwide. The device includes a complete DOCSIS/EuroDOCSIS 1.1 MAC (including QoS) and DAVIC 1.2/1.5 MAC for broadband The BCM7030 is a device that cost-effectively supports the requirements of television and set-top box systems that require high definition, multiple stream standard definition video decoding with the capability of simultaneous high definition and standard definition outputs. The BCM93740 also includes a high-performance MIPS® RISC processor supporting middleware, graphics, applications, and cable modem traffic. The single processor design eliminates the need for multiple processors in the set-top, substantially reducing system cost. The BCM93740 contains a number of peripherals required for next-generation set-top boxes. Some of these include home phoneline networking (HPNA 1/2) for streaming of data and video throughout the home, a VoIP module supporting 2 lines of voice, an IEEE1394 connector for connecting to digital consumer electronic devices, hard disk drive support for digital video recording (DVR), and a POD interface for external conditional access. In addition, a low-cost V.90 softmodem is included for alternative low data-rate connections. The BCM93740 supports industry standard operating systems, middleware, and APIs. Driver source code for these are provided as part of the reference design.
