BCM7110 Single-Chip Set-top Box with DOCSIS
TM
1.1 and PVR System Block Diagram
·
Integrated front-end and back-end results in the most
cost-effective single-chip set-top box solution with
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.
