摘要
介绍了以ST20TP4为主控制芯片控制Sti4600和Sti7000进行音、视频解码的HDTV信源解码器,ST20TP4还负责对前端或LVDS板输入的TS流进行解复用,重点阐明基于32bit微控制器的HDTV信源解码器的硬件设计和软件编程。
This paper introduces the control way that uses32-bit microprocessor ST20TP4to control Sti4600and Sti7000under the Embedded ST20OS.At the same time,ST20TP4is in charge of demultiplexing transport stream coming from front end or LVDS board.This paper focuses on the principle of the hardware and software.[
