摘要
音视频远程监控系统中传输协议的选择对系统的实现至关重要,与TCP协议相比较,RTP协议提供了一种更适合于音视频信息的传输机制,同时广播和多播技术可有效地减轻网络通信的负担,在实际使用中采用HTTP/TCP来传输控制信息,而用RTP/UDP来传输实时声音和图像数据。
Real-time transmission of audio and video data in remote monitoring system is of much practical significance to the system. Compared with TCP, RTP is more suitable for the transmission of audio and video data. Broadcast and Multicast relieve much of the burden of the network communication. In practice, HTTP/TCP are used to transmit control information whereas RTP/UDP are used in real-time transmission of audio and video data.
