Currently the Vorbis patent issue covers these threads: Vorbis development, status & patent issues PART 1 - NON-technical discussion Vorbis development, status & patent issues PART 2 - Technical discussion (This thread) /Moderator comment By looking at this: http://www.xiph.org/archives/vorbis-dev/20...2/index.html#83 it seems that Xiph (at least in 2000) was open to the idea of disclosing the patent research. Is this position changed now, or does it still stand? |

QUOTE (Ivan Dimkovic @ Sep 26 2003, 10:48 AM) I think it was: QUOTE 5853 Michael J. Smithers,Brett G, Crockett,Louis D. Fielder, 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. Ultra High Quality, Video Frame Synchronous Audio Coding But don't take my word for it That's the one, very interesting, I completely missed that one. It does look like a different switching scheme, since they change the amount of overlap. |
