Overview

The VP6 codec was introduced in May 2003. In October 2003, On2 officially released its TrueMotion VP6 codec.

In November 2003, On2 announced that VP6 had been chosen as a codec for China's Enhanced Versatile Disc

, with On2 Technologies earning royalty payments of about $2 USD per player. Then in April 2004 On2 announced that negotiations with E-World had broken down and that On2 would file multiple breach of contract claims against E-World in arbitration proceedings. In March 2005, On2 announced that the arbitrator had dismissed all of On2's claims and had decided that E-World owed nothing to On2. Although E-World included VP6 to its EVD standardization proposal to the Chinese government, it is not clear what, if any, action was then taken by the government. The EVD format initiative appears to be indefinitely stalled.

In November 2003, On2 announced that the VP6 codec will be used in products for broadcasting in the field, such as with BBC
