The Enhanced Versatile Disc (EVD) is an optical-medium-based digital audio/video format, developed by
It was announced on November 18, 2003, by the
The audio codec was to come from Coding Technologies and was called the EAC (Enhanced Audio Codec) 2.0. It is the successor of a prior design known as EAC and works on the basis of spectral band replication. EAC 2.0 supports mono, stereo and 5.1 surround sound. The original plan was that the video codecs VP5 and VP6 from On2 Technologies would be used. These are more efficient than MPEG-2 Video and could enable the disc to store HDTV resolutions, which the standard DVD format does not support. With EVD, royalties to On2 for the VP6 codec part of the EVD design were anticipated to be about $2 USD per video player (a much lower fee than that associated with MPEG-2 Video). However, a contract dispute rapidly developed between On2 and Beijing E-World (the consortium of companies developing the EVD format). On2 announced in April 2004 that it was not being properly paid and would file multiple breach of contract claims against E-World for arbitration. Approximately one year later, the arbitrator dismissed all of On2's claims and ruled that nothing was owed to On2, primarily because no significant number of player devices had ever been produced by the E-World companies. While the EVD format design including VP6 had been proposed to the Chinese government to become a standard, the effort appears to have stalled at that point and no further progress is evident. Following this, very little news was available about EVD until December 6, 2006, when 20 Chinese electronic firms unveiled 54 prototype EVD players, announcing their intention to fully switch to this format by 2008 in an effort to decrease dependency on foreign electronic products and establish a niche in the market. While many devices were made, the format failed to replace the DVD standard.
