A Word about DVD-to-GO

In addition to providing DVD Express for select Armada and Prosignia platforms, Compaq has also qualified the DVD-to-Go hardware MPEG2 decode solution (Compaq Part Number 202861-001). The solution includes movie player software and a PCMCIA Card.

The DVD-to-Go Card includes the following key features:

!Hot Plug & Play Interface with Microsoft Windows 95 OSR2 and Windows 98

!MPEG-2 video and Dolby Digital Surround Sound AC-3 audio

!720 x 480 (16 million colors) video resolution

!Up to 20 megabits per second of sustained video playback

!Multitasking capability

!Backward compatible with video CD and MPEG-1 titles

!Low power usage (1.5 watts) and output (5 volts)

The solution differs from DVD Express in that MPEG2 decode is off loaded to the PC Card, which frees up the processor for other tasks. Off loading MPEG2 decode to the PC Card can improve performance in some cases. More importantly though, DVD-to-Go allows Armada and Prosignia notebooks to play DVD movies where there is no support for a software solution like DVD Express.
