Embodiment Construction
[0029] The present invention provides a CDN-based system and method for streaming media trigger slice on-demand, the method supports trigger slice without manual intervention; when slice processing files, there is no need to cache the entire video file, saving disk space, and When users access slice files, there is no need to download the entire video file, which saves bandwidth and has good flow control.
[0030] The technical scheme of the present invention is described in detail below in conjunction with specific embodiment and accompanying drawing:
[0031] Such as figure 1 As shown, it is a structural block diagram of the first embodiment of the system of the present invention, including: at least one client, a Cache server and a streaming media server, specifically taking one client as an example:
[0032] Client 11 is used to obtain the stream media file of specified format, and sends the described request that obtains stream media file to Cache server;
[0033] Cache...

The invention discloses a triggered slice on-demand system and method of a streaming media based on a CDN (Content Distribution Network). The method comprises the following steps: a client side sends a request for obtaining a streaming media file; according to the received request for obtaining the streaming media file, a Cache server judges whether a slice file corresponding to the specified format of streaming media file is stored or not; and when the slice file is not stored, a streaming media server is used for triggering a slice on-demand server in the streaming media server to automatically generate the slice file corresponding to the request for obtaining the streaming media file according to the request for obtaining the streaming media file, and sends to the corresponding client side. The method adopts a triggered slice technology and does not need manual intervention to carry out slicing treatment for the streaming media file, and an entire audio and video file needs not to be cached, so the disk space is saved. When a user accesses a slice library, an entire video file needs not to be downloaded, so the bandwidth is saved, and flow control is good.
Description
technical field [0001] The invention relates to the technical field of streaming media on-demand, in particular to a CDN-based streaming media trigger slice on-demand system and method. Background technique [0002] With the rapid development of Internet technology, more and more information such as film and television, music, etc. gradually use the Internet as a medium of communication. [0003] Streaming media refers to the media form that transmits audio, video and multimedia files in the network in a streaming manner. Compared with the network playback form of downloading and viewing, the typical feature of streaming media is to compress continuous audio and video information and put it on the network server, so that users can watch while downloading without waiting for the entire file to be downloaded. Due to the superiority of the streaming media technology of the streaming media server, this technology is widely used in video on demand, video conferencing, distance e...
