Experiment of Sixteen-Channel Audio Transmission Over IP Network by MPEG-4 ALS and Audio Rate-Oriented Adaptive Bit-Rate Video Codec

This paper describes an experiment of lossless audio transmission over the IP network and introduces a prototype codec that combines lossless audio coding and variable bit rate video coding. In the experiment, 16 channel acoustic signals compressed by MPEG-4 ALS were transmitted from a live venue to a cafe via the IP network to provide high-quality music. At the cafe, received sound data were decoded losslessly and appropriately remixed for adjustment to the environment at the location. The combination of high-definition video and audio data enables fans to enjoy a musical performance at places other than the live venue at the same time. This experiment motivates us to develop a codec that guarantees audio quality.
