    Abstract: A network video playback method and an apparatus, where location information of an independently decoded frame in a media segment and location information of a non-independently decoded frame that is in the media segment and that references the independently decoded frame are added to a segment index in order to determine a video frame closest to an access time point from the independently decoded frame and the non-independently decoded frame. The independently decoded frame that is referenced by the video frame closest to the access time point is acquired when the video frame closest to the access time point is the non-independently decoded frame, and decoding starts from the video frame closest to the access time point according to the referenced independently decoded frame, and video playback is performed. Hence, access accuracy of network video playback can be improved.

    Abstract: The present invention discloses a video encoding and decoding method, apparatus and system, where the video encoding method includes: determining an independently decodable view in a to-be-encoded picture according to a configuration file corresponding to the video; dividing the picture into at least two tiles, where an area corresponding to one or more tiles that cover the independently decodable view is an independently decodable area; generating an auxiliary message corresponding to the picture, where the auxiliary message includes a location identifier of the independently decodable area; and encoding all tiles included in the picture to form an encoded video bitstream, where the encoded video bitstream includes the auxiliary message. Decoding this encoded video bitstream can lower a requirement for performance of a decoder and improve decoding efficiency.

    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.

    Abstract: The present invention discloses a media data control method and apparatus. The method includes: receiving a control request message sent by a terminal, where the control request message carries identification information of a substream and a uniform resource identifier URI of a media stream to which the substream belongs; obtaining the identification information of the substream and the URI of the media stream to which the substream belongs; determining, according to the identification information of the substream and the URI of the media stream to which the substream belongs, media data of the substream; and performing, based on the media data, a control operation requested by the terminal, for the substream. With the present invention, independent control can be implemented for data of different features under the same type in the case where the data of different features is transmitted through the same media stream.
