PHN 9637 29 1-10-1980 ABSTRACT: "Device for interactive video playback." A device for interactive video playback is based on a playback apparatus for video discs. Such a video disc contains invariably stored video information and possibly also audio information. The various playback and addressing modes can be activated by operation of buttons. The infor- mation read is directly suitable for playback on a tele- vision screen. The playback apparatus is made suitable for executing these playback and addressing modes also under the control of selection signals received from a computer. There is also provided an extraction element for extrac- ting the frame numbers from the information read and for supplying these numbers as data to the computer. The com- puter furthermore comprises a read/write memory for the storage of the information of alphanumerical characters and of selection signals for the playback apparatus. In some cases, the latter signals are activatable only by a ful- filling signal. The computer also comprises an output for said alphanumerical characters as additional display in- formation. There is also provided a keyboard. This key- board is suitable on the one hand for inputting instruc- tions for the computer which are expressed in a higher programming language in order to modify the program to be executed by the computer. It can also be used for producing a fulfilling signal for activating a selection signal read from the read/write memory.
