personal video recording (PVR) and DOCSIS 1.1. PVR engine supports time shifting on a program being viewed and recording of another program simultaneously (watch and record). Dual tuner architecture allows for simultaneous viewing of internet and video or two independent program streams for watch and record PVR. DOCSIS 1.1 quality of service (QoS) enables applications requiring minimum bandwidths, such as VoIP and video conferencing. Support for DOCSIS 1.1, DAVIC 1.2/1.5, and DCII enable deployment in virtually all major markets worldwide. Single high-performance RISC processor is capable of supporting today's demanding set-top box operating systems, applications, and cable modem traffic. External QAM demodulator support for simultaneous DOCSIS and PVR watch and record.

The BCM7110 is a single-chip set-top box device that combines the key aspects required for the next generation of set-top boxes including cost-effective single-chip design, personal video recording (PVR), broadband communication via DOCSISTM 1.1 cable modem, and support of all major global standards for worldwide deployment. The BCM7110 includes dual 1024/256/64-QAM receivers, an out-of-band QPSK receiver and a QPSK to 256-QAM upstream burst modulator. All major physical layer standards are supported for deployment worldwide. The device includes a complete DOCSIS 1.1 MAC (including QoS) for broadband interactive services and DAVIC 1.2/1.5 MAC. The BCM7110 also includes a standard definition MPEG-2 video decoder and 2D/3D graphics subsystem. This allows for the display of studio quality text/graphics and 3D effects. The DVB/DCII transport of the device supports PVR. This support includes time shifting on the program being viewed and recording of another program, simultaneously.
A full PCM audio engine for mixing sounds into the main audio stream is also on-chip. Outputs include left and right analog and SPDIF. The BCM7110 also contains a high-performance MIPS32 RISC processor with 16 KB I cache and 16 KB D cache. The BCM7110 includes a number of peripherals required for next-generation set-top boxes, including USB host and device, Ethernet, IDE controller for connection to disk drives, POD interface for external conditional access, PCMCIA interface, and a glueless IEEE 1394 interface. The BCM7110 also contains support for the Broadcom V.90 softmodem. On-board descrambling supports all major conditional access systems and includes 3DES encryption/decryption for PVR. The BCM7110 represents the most integrated, cost-effective settop box single-chip solution incorporating next-generation requirements. It is built on the previous generation of Broadcom silicon and software to offer a low risk and quick time-to-market for interactive broadband set-top boxes.
