基于软硬结合的无线视频会议系统的设计

Wireless Video Conferencing System Design Based on Software and Hardware

本论文介绍了以OMAP35X,PC及无线通信设备为主要器件的视频会议的系统,系统采用了软件视频会议终端和硬件视频会议终端结构。软件视频终端,是基于PC架构的操作系统,主要依靠CPU处理视、音频编解码,其最大的特点是廉价,且开放性好,软件集成方便。硬件视频终端是基于OMAP35X的嵌入式操作系统,具有体积小、低功耗、成本低和高性能,受环境的影响小等特性。本系统通过实验显示具有较强的实用效果。

This paper introduced the video conferencing system based on OMAP35X,PC and wireless communications equipment,which include software video conferencing terminal and hardware video conferencing terminal structure.Software video terminals is operating system based on PC,which mainly use CPU to process video and audio codecs.Its most important feature is cheap,well open,software,easy integration.Hardware Video terminal is embedded operating system based on OMAP35X hardware with small size,low power,low cost,high performance,little affected by the environment characteristics.Experiments show that the system has strong practical effect.
