Description

The STi7105 uses state of the art process

technology to provide an ultra low-cost, fully

featured HD AVC decoder IC. It is a highly

integrated system-on-chip suitable for STB

markets across all networks (cable/satellite/DTT/x-

DSL/IP) worldwide.

The STi7105 is targeted at the latest Operator and

CE manufacturer requirements for STBs which

utilize advanced HD decoding (H264/VC-

1/MPEG2), and which conform to DVB, ISMA,

ATIS-IIF, SCTE, DirecTV, ATSC, ARIB, CEA, ITU,

OpenCable and MSTV specifications.
