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.
