Abstract
A method and an apparatus for supporting time shift playback in an adaptive Hypertext Transfer Protocol (HTTP) streaming transmission solution are disclosed. The method includes: sending a live media presentation description (MPD) request message to a media server; receiving a response message that includes MPD for a current time period, where the MPD further includes media presentation information for another time period; determining that a moment of a media segment to be requested currently exceeds a time range corresponding to the MPD; acquiring the corresponding MPD according to the media presentation information corresponding to the media segment, and requesting, according to the acquired corresponding MPD, the media segment. In this manner, a client supports time shift playback of a larger time range, and at the same time, the size of the MPD is capable of remaining in an acceptable range.
