Abstract
The invention presents a digital raster timing encoder/decoder system when television raster synchronization pulses and other timing pulses and information data are generated. The invention comprises a digital clock source having coding circuitry which, combined with the clock source, encodes preselected digital signals containing information on raster synchronization control and timing, and also any other information data that is desired. The encoded signal output is transmitted either directly or via some special transmission link, for example by use of a Manchester Decoder clock multiplier (MDCM) system, to a receiving and decoding circuit. The received signal is decoded to create timing signals for operation control of the video television scanning system, and to read out other desired digital data that has been also transmitted within the signal. The system takes advantage of the fact that control signals of conventional synchronization pulses contain large deadband areas within which additional data information may be placed. Such additional digital information may be used to add other control pulse capability, or to add information transmission capability. A principal feature of the system is that only a single channel is needed to transmit synchronization pulses and any additional timing pulses or information of interest.
