摘要： The invention reduces the user-perceived time of switching multimedia channels in a unicast communications system (1). This shortening of the switch procedure is obtained by reducing the buffering of the multimedia data in the data buffer (15) of a user terminal (10). A reduced media buffering results in that multimedia data of the new channel will be rendered in the user terminal (10) in a much shorter period of time. A multimedia provider (100) communicating the multimedia data to the terminal (10) determines a reduced transmission rate that will be temporarily employed for obtaining the buffering reduction. This reduced rate is lower than the normally employed transmission rate and lower than the rendering rate of the media player (12) of the terminal (10). Consequently, the terminal buffer (15) will be emptying in a faster rate than it is replenished and a buffer level reduction is obtained.
摘要翻译：本发明减少了在单播通信系统（1）中切换多媒体信道的用户感知时间。通过减少用户终端（10）的数据缓冲器（15）中的多媒体数据的缓冲来获得切换过程的这种缩短。减少的媒体缓冲导致新信道的多媒体数据将在更短的时间段内在用户终端（10）中呈现。将多媒体数据传送到终端（10）的多媒体提供商（100）确定将暂时用于获得缓冲减少的降低的传输速率。该降低速率低于通常使用的传输速率并且低于终端（10）的媒体播放器（12）的呈现速率。因此，终端缓冲器（15）将以比补充更快的速率排空并获得缓冲器电平降低。

摘要： A method and apparatus for establishing a requested communication session between two terminals (A, B) over a given physical channel, wherein the session requires the determination of session parameters before the session can be executed. It is determined (402) by means of at least one session key, whether any session parameters for a previous session between the terminals have been stored in the terminals. If so, the stored session parameters are retrieved (408), such that the requested session can be executed (410) based on the retrieved session parameters. In this way, delays involved with the establishment of sessions requiring the determination of parameters, e.g. in multimedia calls, can be reduced.

摘要： The embodiments of the present invention relate to methods and arrangements for accomplishing trick modes. This is achieved by assigning samples within a track to sample groups, wherein all samples within a sample group belong to one temporal level and by allowing the client to access one temporal level independently of lower temporal levels. In this way, the flexibility for the client regarding play out of different frame rates is increased which can result in a lower bandwidth utilization.

摘要： In a method of video data compression a video frame in a sequence of frames is divided into a number of macroblocks, a particular macroblock being adjacent to a number of previously coded macroblocks including both intra-coded and inter-coded macroblocks. The method includes selecting either a full prediction or limited prediction type in encoding the particular macroblock to provide a corresponding data bit stream, full prediction using both adjacent inter-coded and intra-coded macroblocks, and limited prediction using intra-coded macroblocks only. A signal is provided along with the bit stream to indicate the selected prediction type to a decoder disposed to recover data from the bit stream. The prediction type may be either signaled explicitly, such as by providing a code word in the bit stream, or may be inferred implicitly by selected values or levels of a coding variable.

摘要： A method of video data compression is provided which is comparatively efficient in compressing data, and at the same time enables transmission of compressed data with sufficient robustness to withstand losses in the transmission channel. A frame of data is divided into coded macroblocks and skipped macroblocks which are grouped into respective slices in a sequence of slices. Respective slices are allowed to contain arbitrary numbers of consecutive macroblocks, and can begin and end at arbitrary positions within the frame. A run-length codeword, comprising a small number of bits, is inserted at the end of a slice to indicate the total number of skipped macroblocks between the final coded macroblock and the end of the slice. To further enhance error resilience an additional codeword, which also indicates the total number of skipped macroblocks, may be inserted at the beginning of the next-following slice.

摘要： A method and apparatus for determining session parameters for a communication session between a first terminal (A) and a second terminal (B). At least the first terminal has stored at least one default set of session parameters. An identifier (404) corresponding to a proposed default set of session parameters is sent from the first terminal to the second terminal. Then, it is determined whether the second terminal accepts the proposed default set of session parameters or not. If accepted (406), the proposed default set of session parameters is retrieved in order to execute the session (408). Otherwise, the terminals fall back to a regular session setup procedure. In this way, delays and bandwidth consumption can be substantially reduced by using a minimum of messaging between the two terminals.
