Digital Tv Ts + Audio + Video Decoder Ic With Built-In Osd Function; Digital Tv 32-Bit Risc Microcontroller - Sanyo EP58B Catalogue

Digital TV TS + Audio + Video Decoder IC
with Built-in OSD Function
LC74152B
Overview
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).
Functions
