Abstract

The invention discloses medial source fast switching method. It includes the following steps: receiving the request information of medial source switching to the flow medial server; switching the request into destination media source and transmitting it to client side by current dialog and media communication channel resource which doesn't be released in request sending. Thus it can greatly reduce waiting time for media resource switching operation, make up the defect in current technique.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for fast switching of media sources. Background technique [0002] With the development of computer networks and the continuous improvement of people's demand for information diversification, the application of Streaming Media Technology is becoming more and more popular. In a broad sense, streaming media technology is a general term for a series of technologies, methods and protocols that enable audio and video to form stable and continuous transmission streams and playback streams. In a narrow sense, it only refers to the IP (Internet Protocol, Internet Protocol) is a new technology for distributing multimedia data streams on the Internet. The streaming media technology adopts the streaming transmission method, that is, the entire multimedia file is divided into compressed packages by a special compression method, and the video server...
