More recently, the JVT has been working on a corrigendum (a list of errata corrections) to the original standard. The drafting work on the corrigendum should be completed in May of 2004.
In addition, the JVT is nearing completion of the development of some extensions to the original standard that are known as the Fidelity Range Extensions. These extensions will support higher-fidelity video coding by supporting increased sample accuracy (including 10-bit and 12-bit coding) and higher-resolution color information (including sampling structures known as [[YUV 4:2:2]] and [[YUV 4:4:4]]). Several other features are also included in the Fidelity Range Extensions project. The drafting work on the Fidelity Range Extensions should be completed in the Summer of 2004.
H.264 is already widely used for videoconferencing, including its support in products of the two main companies in that market (Polycom and Tandberg). It has also been preliminarily adopted as a mandatory part of the future DVD specification known as HD-DVD, now under development by the DVD Forum. A number of broadcasters in Japan and Korea have announced future support for the codec, and it is under consideration for other broadcast use -- for example, it is under consideration in the United States' Advanced Television Systems Committee (ATSC) and in Europe's Digital Video Broadcast (DVB) standards bodies. In the wireless world, it is under consideration for adoption by the 3rd-Generation Partnership Project (3GPP).
