Abstract: A method for forward error concealment encoding of a digital signal data stream including a sequence of individual digital samples, includes encoding one or more of the individual digital samples according to an encoding mode selected from a number of predetermined encoding modes in accordance with a value of the respective digital sample, wherein encoding includes determining an encoded digital sample as a combination of bits of the respective digital sample and a predetermined number of forward error concealment bits arranged into predetermined bit positions of the encoded digital sample in accordance with the selected encoding mode. A method for forward error concealment decoding of a digital signal data stream including a sequence of encoded individual digital samples is provided, and includes decoding one or more of the individual encoded samples into respective decoded digital samples according to a decoding mode selected from a number of predetermined decoding.

Abstract: A method and a system for streaming multi channel digital isochronous data. The method is used for streaming multi channel digital isochronous data, e.g. audio data, in a standard wireless local area network transmission system where bandwidth is reserved for both contention-based traffic and contention free traffic and the audio data formed by samples is organized in audio frames and sent to receivers using multicasting, within consecutive beacon intervals. The contention free traffic of the beacon interval is adjusted to an optimum value, and the length of the beacon interval is adjusted such that a required amount of audio data can be sent to the receivers with minimum system delay.

Abstract: In this application is described a method and a system for collecting streaming multi channel digital isochronous data from multiple independent digital signal sources. The method is used for collecting streaming multi channel digital isochronous data, e.g. audio data, in a standard wireless local area network transmission system where bandwidth is reserved for both contention-based traffic and contention free traffic and the audio data (10) formed by samples (9) is organized in audio frames (174) and sent to receivers (6) using multicasting, within consecutive beacon intervals (137). In accordance with the invention the contention free traffic (138) of the beacon interval (137) is adjusted to an optimum value, and the length of the beacon interval (137) is adjusted such that a required amount of audio data (9) can be sent to the receivers (6) with minimum system delay.
