ABSTRACT:
Apparatus for decoding a serial data stream having remote control informations. Detector means for detecting a serial data stream containing said remote control data are provided to supply a microprocessor with serial data. The microprocessor employs the programming steps of sampling the data at a rate in excess of two times the data rate. The number of consecutive samples of zero bits between samples of a one bit are as counted. A register is loaded with a one bit every time a one is sampled, and loaded with a zero bit when the number of consecutive zeros exceed a predetermined number.
