Features
- Decodes and displays MJPEG images
- Composite and S-Video outputs for VHS recorders and TV monitors
Model 622 is a video output board. Together, the included software and video output board decompress stored JPEG images and generate composite video for VHS tape recorders or for display on a TV monitor. Unlike conventional graphics boards, the 622 does not display the computer's desktop, it only displays the selected JPEG file.
The software program reads JPEG image files, decompresses and transfers them to the 622 board. A video decoder on the board converts the data to NTSC/PAL composite and S-video.
