Zusammenfassung: | Streaming high quality audio/video (AV) from home media sources to TV sets and audio speakers over a wireless local area network (WLAN) is a challenging problem because of the fluctuating bandwidth caused by interference and fading. Retransmission and buffers as common techniques in data transfer over error prone channel are not adequate for delay sensitive applications such as high quality audio streaming. Our approach is to adjust the audio bit-rate dynamically in order to improve the perceptual quality of audio according to wireless channel quality. In this paper we specifically focus on robust audio streaming over short range ISM-band wireless channels. The major strength of the proposed algorithm is in its ability to match the source and channel coding parameters to given channel conditions, thus providing better quality of audio in home networking. |
