基于RTP/RTCP的音视频WiFi传输系统的设计

摘要

本系统设计了一个无线WiFi音视频传输方案,可用于视频监控,视频教学,旅游导游等领域.系统采用i.MX27多媒体处理器,WiFi模块采用基于IEEE802.11b的无线协议,流媒体传输采用RTP/RTCP协议,视频的编解码采用成熟的MPEG4标准,实现基于2.4 GHz无线网络传输的音频流和视频流数据的传输.实现了音视频的WiFi传输,在接收端音视频还原流畅.%This system is designed as a wireless WiFi audio and video transmission project, which can be used in Video Monitoring System, School Teaching and Tourist Guide fields, I. MX27 multimedia processor is the system's processor. Wifi transmission module is based on IEEE802. 11b wireless protocol. RTP/RTCP protocol is used in streaming media deliver, the video codec uses the mature MPEG4 standard, all these realize the audio stream and the video stream transmission based on 2. 4 GHz wireless internet transfers. The system realizes the WiFi transmission of the audio and video, which can be recovered fluency at RX receiver.
