基于DSP平台的数字视频源的系统设计

提出了一种基于TI DSK6711平台的将模拟视频进行数字化处理的系统设计方案，其中视频解码模块完成复合视频信号数字化，音频A／D模块完成语音信号数字化，同时采用大容量的SDRAM存储器作为帧缓存，用FPGA完成其控制接口，整个系统以DSK6711为核心构成数据处理单元，此系统可以完成电视图像信号的去隔行扫描转换、低分辨率向高分辨率转换等视频信号处理，也可以进行实时视频和音频数据压缩处理。

Designing Digital Video Decoder Based on DSP

A systemic design of the digital video decoder based on TI DSK6711 is presented here. In this design, the analog video signal is digitized in the video decode module and the audio analog signal is digitized in audio A/D decode module. High capacity SDRAM memory is used to buffer the digitized frame, the interface of the SDRAM is realized by FPGA. The central data processing unit is completed in DSK6711. This video decoder system can be applied to digital video processing such as de-interlacing, resolution convert, and real time video audio compression.
