摘要
针对某机型原有磁带式记录体质亟需改进,结合现阶段最新音/视频压缩标准设计了机载视频记录仪音视/频压缩存储模块。阐述了最新视/频编解码协议H.264标准,基于该标准采用了专用芯片MG3500设计视频压缩模块。介绍了模块的音/视频压缩部分硬件电路和存储模块的容量设计准则,最后对该模块的应用前景做了简要概述。
A universal audio-video compression and storage module was designed in combination with the newest audio-video compression standard to improve the original tape-recorded recording system. The latest H.264 video codec standard proto-col is described. A dedicated chip MG3500 based on this standard is used to design the video compression module. The capacity design criteria of the partial module hardware circuits and memory modules for audio-video compression are introduced. Finally, the prospect of this module is overviewed briefly.
