Abstract
Transmission scheme for wired networks is inefficient for wireless environment, and a wired / wireless gateway is required for Internet AV streaming. Packet loss protection is done at the wired side, random error concealment is done at the wireless side, and both of them are carried out at the wired / wireless gateway. In this paper, layered transmission scheme for Internet audio streaming using the wired / wireless gateway is focused. PCM and MP3 audio streams are divided into two classes. They are hierarchically encoded using UEP(Unequal Error Protection), and transferred to the gateway. At the gateway, error protection schemes are exchanged according to wired/ wireless characteristics.
