摘要： In order to efficiently handle the switch between user media and announcement media, a basic step is to first determine a configuration of the user media. Next, a configuration of the announcement media to be presented is determined based on the determined user media configuration. Subsequently, the announcement media is configured according to the announcement media configuration, and the configured announcement media is finally sent to the intended user. In this way, the overall appearance or sound of the announcement will be virtually the same as or at least similar to the overall appearance or sound of the user media, preferably without distortions. This allows the user to perceive the announcement as clearly as possible.

摘要： In a method of improved media frame transmission in a communication network. Initially a plurality of “original” or regular media frames are provided for transmission. According to the invention, robust representations of the provided regular media frames are generated and stored locally. Subsequently, one or more of the regular media frames is/are transmitted. The invention detects an indication of a loss of a transmitted media frame, and the idea is to transmit, in response to a detected frame loss, a stored robust representation of the lost media frame and/or a stored robust representation of a subsequent, not yet transmitted, media frame to increase the media quality.

摘要： A receiver includes a detector for detecting a change in source of incoming media during an on-going communication session, and means to provide a reset signal in order to reset decoder states of a decoder in response to such a detected change before decoding new incoming media. In this way, a state mismatch can be avoided without the need for several active decoder instances in the receiver, leading to substantial savings with respect to overall complexity, memory usage and power consumption. This also means that media distortions can be eliminated or at least reduced when the decoded media is finally rendered by a player.
摘要翻译：接收机包括用于检测正在进行的通信会话期间进入媒体的源的变化的检测器，以及提供复位信号的装置，以便在对新的传入媒体进行解码之前响应于这种检测到的变化来重置解码器的解码器状态。以这种方式，可以避免状态不匹配，而不需要接收器中的几个主动解码器实例，导致相对于整体复杂性，存储器使用和功耗的显着节省。这也意味着当解码的媒体最终由播放器呈现时，可以消除媒体失真或至少减少媒体失真。

摘要： The present invention is to select an adaptation scheme for the transmission of the encoded media that results in a satisfactory performance of the transmitted encoded media. A difference from the prior art is that each adaptation scheme defines a set of different transmission formats, wherein each transmission formats is a combination of at least two of the parameters the source codec bit rate, the packet rate, the number of frames of each packet (referred to as frame aggregation), and the level of redundancy. By using the different transmission formats, the transmission can be adapted to different operating scenarios and the performance is hence improved.
摘要翻译：本发明是选择用于传输编码媒体的适应方案，其导致所传送的编码媒体的令人满意的性能。与现有技术的不同之处在于每个适配方案定义了一组不同的传输格式，其中每个传输格式是源编解码器比特率，分组速率，每个分组的帧数的至少两个参数的组合（简称帧聚合）和冗余级别。通过使用不同的传输格式，传输可以适应不同的操作场景，从而改善性能。
