• H04N 5/05 Synchronising circuits with arrangements for extending range of synchronisation, e.g. by using switching between several time constants
• H04N 5/06 Generation of synchronising signals
• H04N 5/08 Separation of synchronising signals from picture signals
• H04N 5/12 Devices in which the synchronising signals are only operative if a phase difference occurs between synchronising and synchronised scanning devices, e.g. flywheel synchronising
