Abstract: 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.

Abstract: A system and method is provided that allows proxy servers to receive capability and preference information concerning user agents (502 and 510) desiring to establish a media session. The proxy server compares the capabilities of the user agents and determines whether an incompatibility exists between them. In the event that an incompatibility does exist, the proxy server may invoke the services of an adaptation server (508) to provide the necessary adaptation required to allow the media session to proceed. The adaptation system allows either the terminating or originating proxy server to make the adaptation determination to allow the adaptation server to modify the offered media session descriptions so that the media streams may be routed through the adaptation server to adapt between incompatible media parameters.
Abstract translation: 提供了一种系统和方法，其允许代理服务器接收有关希望建立媒体会话的用户代理（502和510）的能力和偏好信息。 代理服务器比较用户代理的功能，并确定它们之间是否存在不兼容性。 在存在不兼容性的情况下，代理服务器可以调用适配服务器（508）的服务以提供允许媒体会话继续进行所需的必要调整。 适配系统允许终止或始发代理服务器进行适配确定以允许适配服务器修改所提供的媒体会话描述，使得媒体流可以通过适配服务器路由以适应不兼容的媒体参数。

Abstract: 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.

Abstract: 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.
