摘要
在人烟稀少、边远山区和高原等地区,无线基站覆盖面较小导致无线传输通道环境恶劣,无法有效实现远程高清音视频的实时播放。前端无线手持设备多采用Android操作系统,因此Android系统高质量实时传输高清音视频成为远程视频监控的关键问题。为保证高清音视频的稳定传输,解决网络拥塞和画面延迟抖动等问题,在Android系统上采用RTMP协议传输高清音视频,优化RTMP的数据传输策略,实现了高清音视频的无线传输。在严重丢失帧的恶劣环境下测试该系统,系统运行稳定,显著提高了音视频播放的流畅性和传输的服务质量。
In the sparsely populated, remote mountainous and plateau area, the coverage of wireless base station is small which lead to bad wireless channel environment. It is difficult to realize the real-time remote high-definition audio and video players. Android operating system is used in front end wireless handheld device. Android system has high quality real-time transmission of high-def- inition audio and video to become the key issue of remote video surveillance. In order to ensure the stability of high-definition au- dio and video transmission, and to solve the network congestion, picture delay and jitter problems, this paper on the Android sys- tem by RTMP protocol transmission HD audio and video, RTMP data transmission strategy optimization, realizes the wireless trans- mission of high-definition audio and video. The system is tested under severe environment condition, and the system is stable and service quality of audio and video playback is remarkably improved.
