The method includes: receiving a stream media request from a user, wherein the stream media request carries the Uniform Resource Identifier (URI) of the steam media; extracting request parameters in the URI, wherein the request parameters include the stream media path of the request, the steam media name, and request range information; obtaining a media description file corresponding to the stream media name, wherein the media description file is the file describing the fragment information of audio and video objects; parsing the media description file to obtain the fragment information corresponding to the request range information; converting the URI of the stream media to the URI corresponding to the fragment of the steam media according to the fragment information. Application of the embodiments of the invention can improve the usage rate of the buffer space in a CDN.</p> |
