Digital TV TS + Audio + Video Decoder IC

with Built-in OSD Function

The LC74152B is a digital TV decoder IC that integrates MPEG2 video decoder, AAC audio decoder, transport stream decoder, data

broadcast OSD, video scaler, and NTSC encoder functions on the same chip.

The video decoder down decodes the HDTV stream to 480i/480p. The digital TV backend block can be implemented by combining

this IC with a system controller (CPU).
