In an application example, with at DASH(Dynamic adaptive streaming over HTTP, based on the dynamic adjustment streaming media service of HTML (Hypertext Markup Language)) to transmit segment programs in system be example, based on http protocol, adopt MPEG-2TS stream file as data source, file is called file.ts.
According to the following steps program source is carried out to segmentation according to the method in the present embodiment at server end, generates multiple segmented indexes and segment programs:
1, starting from the position of video image key frame file f ile.ts is multiple segment datas of 10 seconds length according to time cutting, each segment data is MPEG-2TS file, the decoding unit of each segment data all starts with image key frame, the multiple segmentation TS files that obtain like this, called after 1.ts respectively, 2.ts ..., 100.ts;
2, utilize XML form to generate index file corresponding to each little TS file, be used for describing the playing duration of little TS file, the information such as filename.In order to simplify, in this application example by the correspondence setting of segment programs and segmented index for one to one, such as the corresponding 1.ts of 1.index;
3, structure unified resource location URL.
By the multiple little TS file 1.ts after segmentation, 2.ts ... 100.ts and segmented index file 1.index, 2.index ... 100.index is placed on the memory device of HTTP WEB server, generates unified resource location URL simultaneously and identifies first segmented index.
http://ip:port/path/1.index
Program is distributed by the following method in client according to the method in the present embodiment:
1, obtain first segmented index 1.index and 1.ts according to unified resource location URL by HTTP GET method;
2, parse respectively the sequence number of last segmented index in the filename of segment programs and index file body from http protocol head response and response, in this application example, obtaining the segment programs that first segmented index is corresponding is 1.ts, and the sequence number of last segmented index of index file is 100;
Client is obtaining after the sequence number of last index file, just can obtain successively all segmented indexes of index file and corresponding segment programs thereof, a to the last segmented index since second segmented index.
3, obtain second to last segmented index by following URL;
http://ip:port/path/2.index
http://ip:port/path/3.index
……
http://ip:port/path/100.index
Through said process, client gets all segmental files, i.e. segmented index and corresponding segment programs thereof, and from http protocol head response, parse the filename of segment programs, corresponding segment programs is 2.ts, 3.ts, 4.ts ... 100.ts;
