摘要： The present invention is directed to providing a method and apparatus for efficiently compressing and reconstructing a header of a real time communication packet. In a header compressor, a header field value is applied to a modulo X operator which can, for example, divide the header field value by a value X, and output the remainder. Optionally, a checksum may be appended to the remainder. The header field value may be scaled prior to being applied to the modulo X operator. The compressed header field which is output from the header compressor includes the remainder with or without the checksum appended. A header decompressor includes a field reconstructor which reconstructs the received compressed header field in response to the remainder value and range information. The range information represents a range of possible field values which can be reconstructed from the received remainder value.

摘要： A multimedia provider (100) generates, based on a request for a media channel from a user terminal (10), a session set-up description that is returned to the user terminal (10). The description defines, when processed in the terminal (10), a session window (20) that is displayed on a screen (12) of the terminal and comprises a region (22) for displaying media data of a requested channel and a channel region (24) comprising information on alternative available media channels. The description also defines a binding between user inputs (14) of the terminal (10) and identifiers of the alternative channels. The set-up description allows for a user-friendly channel switch by automatically transmitting a channel switch request to the multimedia provider (100) upon a triggering of the user input (14) that is associated with the identifier of the requested media channel. The description, thus, provides a visually appealing graphical interface and simultaneously allows for a user-friendly media channel switch.
摘要翻译：多媒体提供者（100）根据来自用户终端（10）的对媒体频道的请求生成返回给用户终端（10）的会话建立说明。该描述定义了在终端（10）中处理的会话窗口（20），其显示在终端的屏幕（12）上，并且包括用于显示所请求的频道的媒体数据的区域（22）和信道区域（24）包括关于替代可用媒体信道的信息。该描述还定义了终端（10）的用户输入（14）和替代频道的标识符之间的绑定。所述设置描述允许在触发与所请求的媒体信道的标识符相关联的用户输入（14）时，自动向多媒体提供商（100）发送频道切换请求，从而进行用户友好的频道切换。因此，该描述提供了视觉吸引人的图形界面，同时允许用户友好的媒体频道切换。

摘要： The present invention relates to a protection device for detecting at least one faulty phase in an electrical network. The device comprises a band exclusion filter for each phase for filtering away the signals which have the same frequency as the nominal frequency of the network, amplifiers, rectifiers and peak value forming means for each phase. In addition, the different phase signals are fed to a function element which delivers a signal to a level and comparison device for each phase, where the signal is compared with the signals in the respective phase.

摘要： The invention provides a method and apparatus for detecting communication channel delay asymmetry between transmission line protection devices. The method comprises: calculating, repeatedly, clock disparity between clocks of the protection devices and communication delays at different paths of the communication channel; comparing the latest calculated clock disparity and communication delays with previously calculated clock disparities and communication delays, respectively; determining a channel switching has happened if a change of the calculated clock disparity exceeds a first threshold, or a change of the calculated communication delays for any path exceeds a second threshold; and determining the channel delays as asymmetrical if a difference between the calculated communication delays of the different paths after the channel switching exceeds a third threshold.

摘要： A method of managing a unicast-based media session is disclosed. A user terminal having access to channel identifiers of media channels available at a media server compiles a SIP-based channel request comprising a channel identifier of one of the available media channels and a port identifier of at least one media input port of the terminal. This message is sent to a network node for initiating delivery of media data of selected media channel to the announced media input port. The SIP-based data signaling also allows switching between unicast-based media channels and switching between unicast-bast and multicast/broadcast-based media channels during the ongoing media session.

摘要： A stream (1) of media frames (12-16, 22-26, 32-36) is generated by providing multiple media frames (22-26) having respective assigned default timestamps (40) defining rendering times of the media data of the media frames (22-26) according to a default rendering time schedule. Respective alternative timestamps (50) are assigned to at least a portion of the media frames (22-26). These alternative timestamps (50) define alternative rendering times of the media data of the media frames (22-26) according to an alternative rendering time schedule. The alternative timestamps (50) can be used for providing an efficient media rendering when tuning in to the stream (1) at an intermediate position of a frame grouping (20) of the media frames (22-26) thereby missing some of the media frames (22, 24) of the frame grouping (20).
摘要翻译：通过提供具有各自分配的默认时间戳（40）的多个媒体帧（22-26）来生成媒体帧（12-16,22-26,32-36）的流（1），所述默认时间戳定义所述媒体帧的媒体数据的渲染时间媒体帧（22-26）根据默认呈现时间表。相应的替代时间戳（50）被分配给媒体帧（22-26）的至少一部分。这些替代时间戳（50）根据替代的呈现时间表来定义媒体帧（22-26）的媒体数据的替代呈现时间。当在媒体帧（22-26）的帧分组（20）的中间位置调谐到流（1）时，备选时间戳（50）可用于提供有效的媒体呈现，从而缺少一些媒体帧分组（20）的帧（22,24）。
