Re: Video over ATM

Hello,
	FORE Systems also sells a video device that takes in 3 video
(NTSC) and 3 audio sources and sends out a data stream over AAL5. 
There are 2 flavors of the product - one sends raw video, one sends
mjpeg. The device is called the AVA-200 and has software to support
sunos, solaris, HP, SGI and AIX platforms. It works in 8 or 24 bit
color (if supported on platform) and supports 16 bit audio. 
	Software on a workstation can display the video (currently
only if sent raw) or if used in conjunction with a Parallax graphics
adapter mjpeg can be displayed. A control window selects the audio/video
source to view or hear and multiple video streams can be viewed.
	The bandwidth used for a mjpeg stream is around 5-6Mbps
for full 24 bit color. The raw video depends on the size of the
window displayed & 8 or 24 bit color. For more info send a message
to info@fore.com.
