Abstract: The present invention relates to the multimedia field, and discloses a method, a device, and a system for controlling content report behavior. The method includes: receiving a request for subscribing to a configuration update notification, in which the request is sent by the terminal or the media control function, and a configuration update request that is sent by an SCF and carries the new content report configuration information, and sending a configuration update notification message to the terminal or the media control function, where the configuration update notification message carries the new content report configuration information or acquiring information thereof. The method of the present invention avoids using the message body of the SIP message to transmit the content report configuration information, is compliant and compatible with logic for processing a SIP INFO message specified in the RFC 2976.

Abstract: A method and an apparatus for supporting time shift playback in an adaptive HTTP streaming transmission solution are disclosed. The method includes: sending a live 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: In a method, a media delivery server may receive indication information that indicates a man-machine interaction environment of a user corresponding to UE during a call service execution period and that is sent by the UE. Then, the media delivery server may determine, based on the indication information, whether to deliver media content to the UE during the call service execution period. Alternatively, after receiving the indication information, the media delivery server may determine to-be-delivered media content based on the indication information, and deliver the to-be-delivered media content to the UE during the call service execution period. The indication information can reflect the man-machine interaction environment of the user during the call service execution period.

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.
