A Random-Access Audio-Picture Retrieval System
Maynard J. Kuljian · Journal of the SMPTE · 1969
A new technique allows random access to any one of 1,000 or more still pictures. These images may also be synchronized with an audio program. The heart of this system is the video disc which provides a most instantaneous transfer of video information to users. To link these pictures with an audio system, digital picture addresses are added to the audio. These addresses correspond to the video tracks containing the desired pictures. Composite audio program/picture address data are transferred at high speed from the audio reproducer to the user's audio buffer. When this transfer is complete, the user may begin listening to the program and receiving associated pictures.
