Abstract: Embodiments of the present invention disclose a method, apparatus and system for obtaining key information during fast channel switching. A fast channel switching request sent by a terminal is received; at least one data unit bearing key information is generated according to the fast channel switching request; a fast channel switching response message is sent to the terminal, where the response message carries an identifier of a first data unit bearing the key information and the number of data units bearing the key information; and the at least one data unit bearing the key information is sent to the terminal. When the key information is lost, the key information is retransmitted without a need to perform status maintenance, which improves scalability of fast channel switching.

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: A method and an apparatus for sharing a license between SRMs are disclosed. The method includes: a DRM agent obtains the license from a first SRM, and sets the license to a forwarding state locally; the DRM agent deducts one permission of sharing the license; and the DRM agent sends the license to a second SRM. In the prior art, one moving permission is deducted when the license moves from SRM1 to the device, and the other moving permission is deducted when the license moves from the device to SRM2. By contrast, in the technical solution under the present invention, the license forwarded by the DRM agent is set to the forwarding state, and only one sharing permission needs to be deducted, and therefore, the consumption of the sharing permissions is reduced and the subscriber's rights are protected.

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.
