Frame Splitting Scheme for Error-Robust Audio Streaming over Packet-Switching Networks

This letter presents a novel frame splitting scheme for an error-robust audio streaming over packet-switching networks. In our approach to perceptual audio coding, an audio frame is split into several subframes based on the network configuration such that each packet can be decoded independently at the receiver. Through a subjective comparison category rating (CCR) test, it is discovered that our approach enhances the quality of the decoded audio signal under the lossy packet-switching networks environment. key words: perceptual audio coding, audio streaming, frame splitting, packet-switching networks
