摘要： A method and nodes in a communication network for controlling multi-cast delivery of files, wherein the multi-cast delivery is adapted to reduce the amount of required uni-cast file deliveries in the communication network. A browser of an IPTV Terminating Function requiring a file interrogates a cache of the IFT for the file content before a uni-cast request for file delivery is sent to an Application Service Platform. The files stored in the cache have been previously delivered to the IFT via the proposed multi-cast mechanism. If the file content is not stored in the cache, a uni-cast request is sent to the ASP. Each uni-cast request is also forwarded to a Multi-Cast Controller, which determines whether the requested file should be sent also to a plurality of additional IFTs on a multi-cast channel. At each IFT, listening to the multi-cast channel, the received content can be handled selectively according to a filtering mechanism, and a received file may, e.g. be stored in the cache for later retrieval.

摘要： A method and arrangement for switching between a common media stream and a selective media stream of a media session received in a media player including a media buffer entity. Media frames of either a common media stream or a selective media stream are received and buffered in the media buffer entity. A switch at the media buffer entity is then controlled so that the output of the media buffer entity is changed from delivering common media frames to delivering selective media frames, or vice versa, upon detecting a stream switching trigger frame in the received media frames.

摘要： An IMS-enabled control channel for an IPTV service is provided by receiving at a Serving Call/State Control Function (S-CSCF) a Session Initiation Protocol (SIP) REGISTER message, the SIP REGISTER message identifying the originating user, receiving at the originating user a response from the S-CSCF indicating that the originating user has been authorized, and sending a SIP INVITE message from the S-CSCF to establish an open channel connection with a selected IPTV Application Server (AS). This open channel connection can then be used for the transmission of control messages, such as for starting play, starting recording, stopping play, etc., between the STB and the IPTV applications server, as well as for the delivery of personalized content, such as advertisements, voting responses, personalized voting triggers and targeted interactive events. By maintaining an open control channel with the IPTV AS, this offers a substantial reduction in the setup delay times for different applications.

摘要： A method of transmitting a multimedia message over a network. A Message Session Relay Protocol message is generated at a first terminal. The message comprises a plurality of data portions and a description portion, and the description portion comprises instructions for individually handling each data portion. The message is sent from the first terminal such that the description portion is sent ahead of the data portions. When the description portion and data portions are received at a second terminal, each data portions is handled at the second terminal in accordance with the instructions for handling the data portion.
