Introduced: September 1968

Title

Titles differ between systems:

IPC: Synchronising

CPC: Synchronising (for television systems using pulse code modulation H04N7/56)

Full Title

Full titles differ between systems:

IPC:

Details of television systems > Synchronising

CPC:

Details of television systems (scanning details or combination thereof with generation of supply voltages H04N3/00) > Synchronising (for television systems using pulse code modulation H04N7/56)

IPC and CPC are identically structured here. All 4 subcodes exist in both systems.
