摘要： A system and method for transmitting protected real-time content from one user to another is described. In a first aspect, a user sends a Rights Object to another user. In a second aspect, a user sends a Rights Object to another user via an intermediate server for a multiparty communication. In this second aspect, the users may be able to switch between designated Rights Objects as needed.

摘要： An improved system and method for permitting a transmitting electronic device to indicate explicitly which streams in a multimedia stream being transmitted should not be synchronized or should include a specified amount of synchronization jitter. The present invention aids the receiving device in understanding the stream characteristics. The present invention also allows the receiving device to make an informed decision as to whether an synchronization jitter value should be used when synchronizing two or more streams. For certain applications such as uni-directional video sharing or video PoC, the sending device of the stream can indicate that the receiving device doesn't perform any or limited synchronization for better media quality.

摘要： A virtual TV room service configured with a virtual TV room session responsive to a unique session set-up protocol between participants in the virtual TV room session and a conference server unit hosting the virtual TV room service wherein the conference server unit is defined by a unique Session Initiation Protocol Uniform Resource Identifier formed by concatenating the public portion of the Session Initiation Protocol Uniform Resource Identifier signaled in the electronic server/program guide for the mobile TV channel and the private portion of the Session Initiation Protocol Uniform Resource Identifier unique to the virtual TV room community and arranged such that each of the participants in the virtual TV room session is watching the same mobile TV channel. The capabilities of media control that are available to the participants in the virtual TV room session are specified in an XML file configured for communication during the setting up of the virtual TV room session.

摘要： A method (and corresponding equipment) by which a multimedia message is sent from a sending terminal (21) via a messaging server (22)—such as a MMS Proxy-Relay in MMS or a SIP proxy server in SIP IM—to a receiving terminal (25) having limited multimedia capabilities, with the sending terminal (21) adapted to include a user agent (21a) for inserting, into the message, media characteristics of the message sufficient in detail to enable the messaging server (22) to determine whether the message should be transcoded based on actual or assumed multimedia capabilities of the receiving terminal (25), and with the messaging server (22) configured to read the media characteristics and decide whether the message should be transcoded based only on the inserted media characteristics and on actual or assumed multimedia capabilities of the receiving terminal (25). The media characteristics are advantageously inserted into the header of the message.

摘要： Methods and systems for optimizing server polling by a mobile client are described, thereby allowing mobile terminals to conserve battery life by more efficiently using resources such as the processor and transceiver in the mobile terminal A broker system may be used to minimize wireless communication traffic used for polling. A broker stub intercepts server polling messages at the client, multiplexes the sever requests together, and forwards the multiplexed message to a broker skeleton that de-multiplexes and forwards the messages as appropriate. Polling may also be dynamically adapted based on user behavior, or a server guard may be used to monitor changes to data, and notify a client to poll its respective server when the server guard detects new or updated data on that server for that client.

摘要： The present invention relates to a method, terminal device and conference server device for providing a multiparty conference in a data network, wherein an individual presentation layout for participants in a composite video image is selected by a participant and transmitted to the conference serving function. Based on the layout information, a composite signal is generated so that the requesting participant has knowledge of the locations of individual participants' information streams, e.g. video stream, within the composite signal. Thereby, the participant can allocate specific information, such as names, titles or functions, to audio or video streams of the multiparty conference.
