摘要： Audio artifacts due to overrun or underrun in a playout buffer caused by the sampling rates at a sending and receiving side not being at the same rate are reduced. An LPC-residual is modified on a sample-by-sample basis. The LPC-residual block, which includes N samples, is converted to a block comprising N+1 or N−1 samples. A sample rate controller decides whether samples should be added to or removed from the LPC-residual. The exact position at which to add respective remove samples is either chosen arbitrarily or found by searching for low energy segments in the LPC-residual. A speech synthesiser module then reproduces the speech. By using the proposed sample rate conversion method the playout buffer can be continuously controlled. Furthermore, since the method works on a sample-by-sample basis the buffer can be kept to a minimum and hence no extra delay is introduced.

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： A method and arrangement for employing media layer adaptation in a wireless communication of media in data packets from a sending node to a receiving node, by determining a fitting frame aggregation scheme in an effective and accurate manner. An arrival time AT and generation time GT are monitored for packets when received at the packet receiving node. A difference ATdiff in the arrival time of consecutive packets and a difference GTdiff in the generation time of the packets, are calculated. Then, an inter-arrival measure IA is calculated as the deviation between the arrival time difference ATdiff and generation time difference GTdiff. When the inter-arrival jitter exceeds a preset threshold (Th), a frame aggregation scheme is determined based on the calculated inter-arrival jitter IA and applied in the packet communication.

摘要： A packet scheduler reduces or “compresses” the packet transmission delay jitter or delay range where packets experience little or no scheduling delay before transmission. As a result, the number of packets that experience little or no delay is reduced. A preferred example way of compressing the packet transmission delay jitter is to reduce the transmission priority of low delay packets. Compressing the delay jitter is particularly desirable for services like VoIP that require low packet transmission delay jitter.
摘要翻译：分组调度器减少或“压缩”分组传输延迟抖动或延迟范围，其中分组在传输之前经历很少或没有调度延迟。结果，减少了经历很少或没有延迟的数据包的数量。压缩分组传输延迟抖动的优选示例方式是降低低延迟分组的传输优先级。压缩延迟抖动对于需要低分组传输延迟抖动的VoIP这样的服务是特别需要的。

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： User equipment in a wireless communication system monitors scheduling information and locally detects a change in link data rate of the uplink channel based on the monitored scheduling information. In this way, a change in link data rate can be detected directly without significant delay. This direct or early detection of a rate change is then combined with an appropriate system reaction. The information of the detected change in link data rate is preferably utilized for adapting the application data rate of an IP application running in the user equipment. As an alternative, or as a complement, data packets are classified based on relative importance and selected for transfer of information over the uplink channel based on the classification of data packets and in dependence on the detected change in link data rate.

摘要： Perceived interactivity in user communications is achieved by reducing a perceived delay switching the active transmitter in the communication without having to reduce actual transmission and setup delays associated with a communication exchange. A sound signal is identified in the user communication. The sound signal is analyzed to identify or estimate a sound signal segment. The sound signal segment is preferably (though not necessarily) located at the beginning or the end of the sound signal. The sound signal segment may be selected directly from the sound signal itself, from a modified version of the sound signal, or from a signal associated with the sound signal. A determination is made that a length or duration of the sound signal segment should be or can be modified. One or more modifications for the sound signal segment are determined and are provided to one or more processing units to perform the modification(s).

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。
