Description

The STi7197 is an advanced STB decoder with

an integrated QAM demodulator, suitable for

cable networks conforming to the ITU-T J83-

Annex B standard (for example, US cable).

The STi7197 includes multi-stream transport

demultiplexing, audio video decode, video

processing, graphics and display handling, STB

peripherals, audio video DACs, digital audio video

outputs, PCI, e-SATA, dual USB ports, an

Ethernet GMAC controller and ST40 applications

CPU.
