Abstract: A television sync signal generator adapted for ready conversion among various television standards includes a memory (216) in which information related to the magnitude of at least one component of a composite sync signal is stored at address locations each corresponding to at least one particular time in each recurrent television frame. A clock signal generator (212) addresses the memory (216) to sequentially read out the information so the sync signal can be reconstructed. By dividing the sync signal into four intervals which are selected by paging signals from one counter, a reduction in required memory capacity is achieved. For further reducing the number of memory addresses required, each memory address contains information relating to the instantaneous resolution or clock rate. A sample rate controller (820) is coupled to the memory for having the instantaneous clock address rate controlled in response to the contents of the memory.
