一种增强嵌入式网络视频编解码器可靠性的方法

A Method to Enhance the Reliability of Embedded Network Video Codec System

在嵌入式网络视频编解码系统中,由于用户配置的错误,或者某个视频解码器的故障,如不能及时检出并得到正确的处理,不仅会造成所在通道的无效工作,也可能引起整个视频编解码系统性能的下降,甚至可能引起整个视频网络的瘫痪。为解决这一问题,基于网络通信检测原理,在嵌入式网络视频编解码器中,同时引入了UPnP检测机制和"心跳"检测机制,在用户配置错误和解码器出现故障时,都能迅速实现故障告知,从而提高了视频网络编解码系统的可靠性。

There exists a problem in embedded network video encode/decode system, such as an incorrect user configuration, or a failure in one decoder, which may cause the failure of whole system if not be detected and treated in time. Now the problem is solved by a solution that combining both the UPnP and heartbeat test mech- anism. The incorrect configuration, as well as the failure of a decoder, will be informed to or be detected by the related encoder in the network. In this way, the reliability of the embedded network video encode/decode system can be improved obviously.
