TELEVISION SYNCHRONIZING APPARATUS A television signal synchronizer is provided in which non-synchronous signals are written into memory storage, while previously stored video signals are read-out of the memory storage synchronous with a local reference. A memory control circuit, responsive to the write and read ready signals, prevents the simultaneous reading and writing of the memory storage by generating memory control signals for reading stored video signals out of the memory at a periodic rate synchronous with the read signal, while generating write-into memory control signals at a nonperiodic rate determined by the same read signal. |
