DESCRIPTION

The STi5500 is the first of a new generation of integrated multimedia decoder engines for set top

box and DVD applications. It offers a high level of integration by reducing the complete set top box decoding chain from Transport Demux to PAL/NTSC Encoder onto one chip. At the same time

it dramatically enhances CPU and Graphics per formance, and cuts down total system memory cost.
