Description
The ST-7104 uses state of the art process
technology to provide a cost effective, fully
featured HD AVC decoder IC. It is a highly
integrated system-on-chip suitable for low-cost
add-on module for iDTV manufacturers.
The ST-7104 is targeted at the latest CE
manufacturer requirements for iDTVs which utilize
advanced HD decoding (H264/VC-1/MPEG2),
and which conform to DVB, SCTE, ATSC, ARIB,
CEA, ITU and OpenCable specifications.
