摘要
提出一种全数字的可视对讲系统解决方案。可视对讲系统由内置多媒体处理单元MPEG-4编码器的ARM9处理器GM8120以及外部的音视频采集模块构成。该系统采用了嵌入式Linux操作系统和MPEG-4视频编解码技术,保证了可视对讲系统对实时性和图像清晰度的要求,并为MPEG-4在可视对讲系统中的应用提供了一套完整的解决方案。
An all digital video intercom system is designed. It consists of ARM9 processor GM8120 with a multi-media processing unit MPEG-4 encoder and external audio-visual acquisition modules. The system uses embedded Linux operating system and MPEG-4 video encoding and decoding technology, which guarantees the real time performance and image definition of visible interphone system and pro- vides a set of full solutions for MPEC-4's application in video intercom system.
