Direct to Digital You can transfer your digital images and/or data directly to a digital DVD in real time via an "i-Link" connection. A 400Mbits/sec 'FireWire' standard. One hour of high quality recorded video on a camcorder equals the content of a 4.7Gb DVD.
High Quality Picture
DVD delivers far and away the best colour, sharpness
and clarity in home video, far surpassing the Laserdisc
standard. DVD also offers high resolution, with exceptional
rendering of fine picture detail. Video distortion
is extremely low, which reduces unwanted color 'noise'.
And because DVD is an optical format, the picture
quality doesn't degrade over time and repeated use.
High Definition DVD
HD-DVD is an up and coming future standard for DVD, allowing for -initially- 15-20Gb capacities and 48Mbits/sec recording potential. In comparison, the current standard in DVD (480i and 480P) has a single layer capacity of 4.7Gb and a recording capability of 8Mbits/sec (commonly known as SuperBit), but in practice it averages at 2-6Mbits/sec to get an entire 2 hour movie on the disc. The display resolution commonly associated with it is 640x480. At the other end of the scale, High Definition in its ultimate form is a standard capable of 1920x1080 (1080P) and, at the basic level, 1280x720 (720P). Both are native high resolution widescreen displays. To store this amount of super-high video quality, you need 4 times the capacity and a video bit rate of 10-12Mbits/sec.
The best place to start is with IMAX's standard 4.7Gb DVD WMVHD titles available from www.amazon.com and with Microsoft's recent introduction of Windows Media Player 10 for Windows XP you have the capability to playback HD DVD/Digital content at 1080P with ease.
