Apparatus is described for converting the digital output of a microprocessor system into a video signal. The video signal is thereafter applied to a television receiver to cause objects described and controlled by a microprocessor system to be displayed on the television receiver. The apparatus is specifically used to provide an interface between a microprocessor controlled video game and a television monitor or receiver.

Apparatus for converting digital data into a video signal for displaying

Method and apparatus for serial data transmission wherein each data word has a fixed bit length and each bit is transmitted during a fixed duration data period following a sync pulse. The sync pulse for each data word has a duration equal to a data period. Each data bit pulse has a duration less than a data period. The method and apparatus is particularly suitable for remote control systems for use with television receivers.

Method and apparatus for digital data transmission in television

An audio control system for altering the frequency content of an audio signal with a d.c. control voltage. An audio signal is divided into a plurality of signal channels representing different portions of the audio signal frequency spectrum. Each signal channel is terminated by an attenuator which is responsive to a d.c. control voltage. The attenuated signals are then combined. By changing a d.c. control voltage a change in tone, volume, balance or loudness of an audio signal in a stereoamplifier or the like may be achieved.
