摘要
流媒体传输是流媒体技术的关键技术,在视频点播、网络会议等具有广泛应用意义。本文在结合MPEG-4视频标准和RTP/RTCP协议的基础上,提出一种适合目前嵌入式视频点播的流媒体传输方案,在Linux系统下开发使其具有很强的可移植性,采用了适用于MPEG-4视频传输的RTP封装格式和组包算法,并对其传输系统的结构和流程作了详细的探讨。实验表明,本系统在局域网已经实现并可以初步应用于嵌入式开发。
Streaming media transmission is the key streaming media technique and used widely in VOD(video on demand),video meeting and so on. This paper presents a transmission scheme which suited for embedded VOD by combining the MPEG-4 video standard and the RTP/RTCP protocol, and has good transplantation. The RTP encapsulation format and packing algorithm for MPEG-4 video is used and the architecture and implementation process are described in detail. Experiments show that this transmission system can be use in emb...
