Abstract: A method for implementing fast playout includes receiving a fast playout request sent by a client, where the fast playout request comprises a Uniform Resource Locator (URL) corresponding to content of a media file with a specified multiple of regular playout rate by the client, and the specified multiple of regular playout rate is determined by the client according to obtained media presentation description; and obtaining a content segment corresponding to the media file with the specified multiple of regular playout rate according to the URL, and sending a fast playout response to the client, where the fast playout response comprises the content segment corresponding to the media file with the specified multiple of regular playout rate. Therefore, fast online playing is implemented, and user experience is improved at the same time.

Abstract: The present invention provides a media sending method, a media receiving method, and a client and a system. The media receiving method includes: receiving a media presentation description, where the media presentation description includes 3D format description information of a video; selecting a presentation according to the 3D format description information, and sending a segment obtaining request to a server corresponding to the selected presentation according to segment information in the media presentation description, where the segment obtaining request is used to obtain a segment of the selected presentation; and receiving the segment requested by the segment obtaining request. The present invention solves the disadvantage of the prior art that a receiver can receive 3D format description information only long after starting media reception, and shortens the time of determining, by the client, the 3D format used by the video in the received media.
