基于4G网络的手机视频直播系统方案设计与实践

4G Network Based Live Broadcasting System on Mobile Phone

近几年来,随着无线网络通信技术的不断发展,以3G甚至4G网络为基础的视音频信号无线回传直播系统相继涌现并被大量电视台所采用。但这类设备存在着价格不菲,体积较大且沉重,耗电快需要配备大容量备用电池等弊端。河南电视台经过大量的实验和测试之后,成功搭建起了一套以高性能智能手机为基础,利用4G网络进行视音频实时回传的低成本直播系统。

In recent years, with a continuous development of wireless network communication technology, wireless transmission broadcasting system based on 3G / 4G network has been adopted by a large number of TV stations. But such devices are expensive and bulky which are equipped with a large reserve battery. After a great deal of experiments, Henan TV Station successfully sets up a low-cost live-streaming system based on high performance smart phones through 4G network for real-time transmission.
