BCM7115 Single-Chip Set-top Box with 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)

PVR engine supports time shifting on a program being

viewed and recording of another program

simultaneously (watch and record)

Support for DAVIC and DCII enable deployment in

major cable markets worldwide

Industry-leading compact form factor design is

enabled by high integration

High-performance RISC processor can support

today's demanding set-top box operating systems and

applications

External QAM demodulator support for PVR watch

and record
