Single-Chip Cable Set-Top Box with PVR
The BCM7115 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), communication via DAVIC or other protocol and support of all major global physical layer standards for worldwide deployment.
The BCM7115 includes a 1024/256/64-QAM receiver, an out-of-band QPSK receiver and a QPSK/16-QAM/256-QAM upstream burst modulator. The device includes a complete DAVIC 1.2/1.5 MAC for interactive services.
An integrated MIPS32 RISC processor is intergrated running todays OS, middlewares, and applications. Other major blocks included are an encryption/decryptioin engine for conditioinal access and PVR, a 2D/3D graphics subsystem, and audio engine.
