Abstract: 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 format 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.

Abstract: Low rate data signals, such as standard TTY signals and standard DTMF signals, can be effectively analyzed and encoded by speech encoders employed in conventional digital cellular system. This is accomplished by providing a low rate data encoder in the transmission path of the low rate data signal, just prior to the speech encoder used by the digital cellular system. In so doing, the standard, low rate data signal is transformed (i.e., modified) by the low rate data encoder into a signal that is more compatible with the speech encoder. Similarly, a low rate data decoder is provided at the receiving end of the transmission path to decode the modified, low rate data signal.

Abstract: It is a basic idea to determine (S1) the characteristics of a jitter profile measured over a plurality of packets, and classify (S2) the jitter profile based on the determined characteristics as well as information representative of the particular access used for communication between the sender and the receiver. The classified jitter profile is then matched (S3) to an appropriate action for media layer adaptation so that a proper action for media layer adaptation can be initiated (S4).

Abstract: An apparatus for controlling utilization of RTCP bandwidth for compound and non-compound RTCP packets is described. This apparatus includes a bandwidth detector (10) determining available RTCP bandwidth and a channel quality detector (12) determining channel quality. A bandwidth divider (14) connected to the bandwidth detector and the channel quality detector divides the available RTCP bandwidth between compound and non-compound RTCP packets based on the determined channel quality.

Abstract: Un método para adaptar a diferentes condiciones de funcionamiento la transmisión de contenido multimedia codificado (802) en una red de conmutación de paquetes, donde están disponibles una serie de formatos (808) de transmisión, en el que cada formato (808) de transmisión define una combinación de por lo menos dos características; comprendiendo dicho método las etapas de: recibir (1105) información acerca de si la métrica de rendimiento del contenido multimedia codificado (802) transmitido satisface un objetivo predeterminado (814), si la métrica de rendimiento del contenido multimedia codificado (802) transmitido no satisface el objetivo predeterminado (814); seleccionar (1106) otro formato (808) de transmisión entre los formatos (808) de transmisión disponibles, hasta que la métrica de rendimiento del contenido multimedia codificado (802) transmitido satisfaga el objetivo predeterminado, caracterizado por que dichas características son combinadas entre las de agregación de tramas, velocidad binaria de codificación fuente y redundancia.
