It may contain preliminary or speculative information, and may not reflect the final version of the product.

The Enhanced Versatile Disc (EVD) is an optical medium-based digital audio/video format, developed to provide a means for playing HDTV content using existing optical media. It was announced on November 18, 2003 by China's Xinhua News Agency as a response to the popular DVD-Video format and its licensing costs (which some considered excessive). It uses an optical storage medium in CD size (120 mm) that is physically a DVD disc with the same UDF file system. China started development on EVD in 1999, because DVD Video (CSS, Macrovision, etc.) and MPEG-2 (Video and Systems) licensing costs were relatively high — reportedly in the range of $13–$20 USD per hardware video player.

On the EVD, the video codecs VP5 and VP6 from On2 Technologies were supposed to be used. These are more efficient than MPEG-2 Video and could enable the disc to store HDTV resolutions, a feature the DVD could not offer when using MPEG-2. 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 moderately 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. TrueMotion VP6 is a video codec developed by On2 Technologies as a successor to earlier efforts such as VP3 and VP5. ...

Prototype EVD discs and software players were presented in April 2004. As the disc is physically a DVD disc it could be read with any computer DVD drive. Successful copies were made with DVD-R disks. The number of films ever offered in the format was very limited. 2004 (MMIV) was a leap year starting on Thursday of the Gregorian calendar. ...


Very little news has been available about EVD since the contract dispute with On2 broke out in the Spring of 2004.


On Wednesday, December 6th, 2006, 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. Although earlier attempts have been made, none have had such widespread support as this.
