摘要： A method and system for updating or handling the update of a media path between a first user terminal and a second user terminal in a telecommunications network is provided. According to an embodiment of the present invention, the media path includes one or more gateway nodes. Each gateway node includes a gating function for gating media packets. Each gating function has an associated controlling function for controlling the gating function. Responsive to a message indicating at an update of the gating at the gating function is required, the gating function arranges for a new gating to be opened while keeping the old gating open. The gating function determines when the media has been switched to the new path. Responsive to the determination, the gating function arranges for the old gating to be closed.

摘要： Different representations are associated with an instance of media content, and a representation can include multiple portions of media content. A respective quality value and bitrate can be associated with each of the portions. Information about the instance of content, including bitrate and quality information, can be accessed by and/or sent to a client. The quality information indicates the availability of measures of quality (e.g., quality values) and where those quality values reside or how they can be retrieved. The client can use quality as well as bitrate to make more intelligent decisions while streaming the content. For example, while the content is being downloaded over a network, the client can adapt to changes in available network bandwidth by selecting one portion of the instance of media content over another based not just on its bitrate but also based on its quality value.

摘要： In one example, a streaming media player may select at least one media stream from a plurality media streams based on network conditions. A communication interface may receive a chosen media stream having a chosen bitrate and an alternate media stream having an alternate bitrate on a communication network and configured to determine a bandwidth average for the communication network. An adaptive streaming selector may switch from the chosen media stream to the alternate media stream based in part on the bandwidth average. A media pipeline may render the chosen media stream into a chosen media presentation and the alternate media stream into an alternate media presentation. An output device may present the chosen media presentation and the alternate media presentation to a user.

摘要： A method for service content distribution under a heterogeneous network and a service management platform are provided. The method includes that the service management platform stores and maintains the context information of a network and a terminal, and the service management platform makes a query to obtain an index of the context information according to a received service request, selects a cooperative network and terminal for service content distribution, and performs service content distribution according to the selected cooperative network and terminal. Accordingly, a proper network and a proper terminal can be selected according to a service request under a heterogeneous network, terminals in a surrounding environment of a user are fully utilized, and radio resources are further fully utilized.

摘要： A Method is described for synchronizing the output of terminals. The method according to the invention may be used in a system comprising a station, which transmits a packetized stream to at least a first and second terminal. Each terminal comprises a variable delay unit and each terminal is connected through a low-delay communication channel to at least one synchronization unit for calculating delay information. Further, each terminal is capable of determining media reference information of a received media unit from the stream. The method comprising the steps of providing one or more low delay communication channels between the terminals and a synchronization unit; the synchronization unit calculating delay information on the basis of synchronization information received from the terminals via the one or more low delay communication channels; and transmitting the delay information to at least one of the terminals allowing the at least one terminal to delay its output such that the output of the terminals are substantially synchronized.

摘要： A method, system and apparatus for monitoring error correction data are provided. The method comprises receiving an authorization request defining a media session between an AF server and a mobile device from the AF server. The authorization request contains a media packet flow identifier and a corresponding forward error correction (FEC) packet flow identifier. The method includes deploying policy rules for the media session to a gateway server, the policy rules including the media packet flow identifier and the FEC packet flow identifier; receiving periodic reports from the gateway server, the reports including packet counts for each of the media packet flow and the FEC packet flow; determining whether bandwidth consumed by the FEC packet flow exceeds a predetermined threshold; and when the determination is affirmative, sending an action request to the AF server.
