3G移动可视电话系统设计

摘要

The architecture of 3G video telephone system design is presented. Based on Windows CE system, integrated VT App, 3G-324M protocol stack, RIL and dual port Ram to realize the complex multi-media system-video telephone design. The operational principle and contrivance are described, and the VT system work flow by analyzing the process of dialing and accepting the call is expatiated.%介绍了3G移动可视电话的设计架构模式,基于Window CE操作系统,结合vT App、3G-324M协议栈、音视频设备驱动、RIL和双端口RAM等相关模块,实现了可视电话这一复杂的多媒体应用系统的运行,描述了相关模块的工作原理与设计思路,并通过对呼出流程图加以介绍的方式,对可视电话系统的运行流程加以阐述.
