HOW ARE IMAGES AND SOUNDS VIEWED ON A VIDEODISC?
The playback of stills, motion sequences and sound from a videodisc is similar to that of a standard home VCR. The output signal is fed to a television set or monitor. In most interactive training scenarios, the videodisc requires what is often called a “two screen solution” in which the computer-based materials are displayed on a computer monitor and the videodisc images are seen on a TV set. Many users channel the output of the videodisc signal through an analog-to-digital image capture card, thus allowing the disc images to be viewed through the computer monitor (“single-screen solution”).
