Ultra-High Quality Video Frame Synchronous Audio Coding
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 five-point audio impairment scale at a bit rate of 256 kbit/s 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.
