高清晰度数字电视中的单片视频处理器

Single-chip Video Processor for Digital HDTV

介绍日本目前广泛使用的单片视频处理器，它能把TS解码影、MPEG2 MPHL解码器和OSD控制器集成在10．2mm×10．2mm的单块芯片上，并为SDTV和HDTV提供高分辨率的显示输出和多格式的数字广播。由于该芯片具有数字电视的4个通道解码／显示、多角度广播、无缝显示、音频／视频(AV)同步、IP转换和误差抑制功能，所以在数字电视和BS数字电视广播中获得广泛应用。

The paper introduces single-chip video processor which is widely used in Japan now.It can integrate TS decoder, MPGE2 MP~@ HL decoder and OSD controller in single-chip(10.2mm×10.2mm)and can supply for all the formats of digital broadcasting and digital output on the'Hi-vision'(high-definition)in SDTV and HDTV.The device has 4-channel decoding/ display,multi-angle broadcasting,seamless display,audio/video(A/V)synchronization,IP conversion and error suppress functions for digital TV,therefore,it is widely applied in digital TV and BS digital TV broadcasting.
