可擦写HD DVD光盘的标识

　　DVD论坛指导委员会（Steering Committee）日前召开会议，就包括下一代光盘规格之一的“HD DVD”在内的13项议题进行了投票（投票结果，英文）。根据投票结果，批准通过了HD DVD的追记型媒体规格“HD DVD-R”的1.0版物理规格。播放专用媒体规格已于2004年6月的会议获得通过、可擦写的媒体规格也于当年9月的会议上通过了正式版1.0版。至此，HD DVD所有媒体的物理规格均成为正式版本。此次会议还通过了HD DVD-R文件系统0.9版。

　　其中规定了HD DVD-Video光盘在存放影像数据时的编码方式具体细节。虽然过去已经规定了在编码时应根据需要分别使用H.264/MPEG-4 AVC（以下称为H.264）、VC-1、MPEG-2，但对于如何选择具体规定编码时使用的工具与参数等的规范则成为了下一项讨论的焦点。2004年12月的会议上，决定VC-规范采用“高级规范（Advanced Profile）”，而此次会议正式决定H.264采用“High Profile”。也就是说HD DVD播放器必须支持VC-1的Advanced Profile与H.264的High Profile解码。

可擦写媒体规格命名为“HD DVD-RW”

　　除此之外，还决定HD DVD规格的著作权保护方式采用AACS（高级内容访问系统），同时确定了可擦写媒体规格的标识。过去可擦写媒体规格一直被称为“HD DVD-ARW”，新确定的标识则为“HD DVD-RW”。法国汤姆森公司提议的在HD DVD上采用“Film Grain Technology遭到否决。（记者：新井将之）
