The capabilities of the ordinary 33 1/3 RPM phonograph record for high information packing density, ease of handling and cheapness of quantity reproduction have been utilized in the development of a still-picture television system called Phonovid. Up to 400 still pictures with accompanying audio can be recorded on a 12 inch record. The played-back signal, when processed through a scan converter, is a standard EIA television signal. This paper will describe the Phonovid system, and a working demonstration will be provided.
