Microsoft's VC1 video codec is a fully scalable video technology that produces high-quality video at low data rates. With VC1 support, InterVideo-Ulead customers can enjoy video resolutions of up to 1080p--approximately six times the resolution of today's DVD video. The HD DVD format also provides higher disc capacities than the current 4.7GB DVD formats--an HD DVD disc will provide up to 30GB (15GB per layer).
DTS-HD provides audio for new HD DVD format standard, while offering playback in legacy equipment, such as existing home theater systems. In addition to being able to support a virtually unlimited number of discrete surround sound channels, it can downmix to 5.1- and two-channel, and can deliver audio quality at bit rates extending from DTS Digital Surround up to lossless.
The InterVideo-Ulead HD DVD Authoring Tool and WinDVD HD DVD, InterVideo's high-definition DVD content playback software, were made possible through the combined efforts of Microsoft, DTS, InterVideo, and Ulead. For navigation and playback of content on an HD-DVD and BD disc, users will be able to use InterVideo's flagship product, WinDVD HD. The next release of WinDVD HD will be available in the near future, according to InterVideo.
