VideoBeam projection TV system
Advent developed the first consumer projection TV system, the VideoBeam. I only saw these a few times, usually in bars. The video projection unit was paired with a separate, stand alone screen, positioned about 15 feet away. I recall that the audio was also 'projected' so that it bounced off the screen, along with the picture. The picture was good and bright, on axis, but contrast and brightness suffered off-axis. I don't know much about this product, except that, as with most other Advent products, it was innovative.
