    • 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).

    • 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.
    • 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。

    • A method and system for parallel encoding of frames in a video are described, exploiting parallel processing at both frame and slice levels. One or more slices are processed in a preceding frame by one or more cores in a multi-core processor, and a slice is processed in a succeeding frame provided at least one of said one or more cores in the multi-core processor is available for processing; and the processing of a slice from said one or more slices at same physical location in the preceding input frame has been completed, the processing of frames and slices in the preceding and succeeding frames being performed at least partially in parallel. A significant speedup in comparison to the sequential encoding approach is achieved while maintaining high visual quality for the output video. A corresponding system for parallel encoding of a video is also provided.

    • The invention relates to a method for providing a terminal MS2 of a communications system with coded still image signals. In order to enable a further content adaptation for multimedia messages, it is proposed that the method comprises receiving coded video signals at a network element of said communications system, converting at least a part of said received coded video signals in said network element to coded still image signals, and delivering said coded still image signals to a terminal MS2 of said communication system. The computation required for said conversion can be minimized by exploiting the commonalities of video and still images compression methods that are based on the Discrete Cosine Transform scheme. Thus it is rendered possible to provide excerpts of transmitted video clips also to terminals not capable of handling at least this particular video clip. The invention equally relates to a corresponding communications system, network element and module for a network element.
    • 本发明涉及用于向通信系统的终端MS 2提供编码的静止图像信号的方法。 为了能够对多媒体消息进行进一步的内容适配,提出了该方法包括在所述通信系统的网络元件处接收编码视频信号,将所述网络元件中的所接收的编码视频信号的至少一部分转换成编码静止 图像信号,并将所述编码的静止图像信号传送到所述通信系统的终端MS 2。 通过利用基于离散余弦变换方案的视频和静止图像压缩方法的共同性,可以最小化所述转换所需的计算。 因此,可以将传输的视频剪辑的摘录也提供给不能处理至少该特定视频剪辑的终端。 本发明同样涉及相应的通信系统,用于网络元件的网络元件和模块。
