Convention Paper

Ultra High Quality, Video Frame Synchronous Audio Coding

Authors: Smithers, Michael J.; Crockett, Brett G; Fielder, Louis D.

AES Convention 114 · Paper 5853 · March 2003

Abstract

Two methods of coding and delivering ultra-high quality audio are presented. Both methods are video frame synchronous and editable at common video frame rates (23.98, 24, 25, 29.97 and 30 frames per second) without the use of sample rate converters. The first is an ultra-high quality audio coder that exceeds 4.8 on the ITU-R 5 point audio impairment scale at a data-rate of 256 kbps per channel and at up to three generations of encoding/decoding. The second is an enhanced method of video frame synchronous PCM packing. Specifically the problem of transmitting 48 kHz audio in 29.97 Hz frames is examined.
