H04N 3/18

Generation of supply voltages, in combination with electron beam deflecting

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Scanning details of television systems; Combination thereof with generation of supply voltages > by means not exclusively optical-mechanical > by deflecting electron beam in cathode-ray tube > Generation of supply voltages, in combination with electron beam deflecting

CPC:

Scanning details of television systems; Combination thereof with generation of supply voltages > by means not exclusively optical-mechanical (H04N3/36 takes precedence) > by deflecting electron beam in cathode-ray tube > Generation of supply voltages, in combination with electron beam deflecting

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

IPC defines codes here since 1980.
