being used requires a count of clock pulses less than the maximum count of which counter 212 is capable the counter may be reset at the proper count representing the number of clock pulses in one field or one frame as required the reset is accomplished by a pulse generated by rom 216 and applied over a conductor or line 222 to counter 212 it should be noted that the reset information requires another one bit section of memory in rom 216 consequently the data path of rom 216 must be a minimum of 3 bits in width other synchronization and control signals can be provided by rom 216 for example output 220 can provide a burst flag in this case each rom memory location must have a storage capacity of four bits two of which are used as described to generate the composite sync and blanking signal and one of which resets the counter as described above and a further one of which is used to control the instantaneous value which the burst flag is to have in a similar manner other control signals such as horizontal and vertical drive can be provided by providing sufficient additional memory capacity the above described arrangement carries the information to generate television sync and blanking signals for any desired standard in the form of the programming of various memory locations change from one standard to another within a particular piece of equipment can be accomplished by changing the program rom 216 or alternately by replacing the rom with one appropriately programmed reprogramming of rom prom such as one which can be erased by ultraviolet light eprom is accomplished by first erasing the unwanted current program and using an appropriate.
