- H04N 9/01 Circuitry for demodulating colour component signals modulated spatially by colour striped filters by phase separation
- H04N 9/03 Circuitry for demodulating colour component signals modulated spatially by colour striped filters by frequency separation
- H04N 9/11 Scanning of colour motion picture films, e.g. for telecine
- H04N 9/12 Picture reproducers (H04N9/11 takes precedence)
- H04N 9/43 Conversion of monochrome picture signals to colour picture signals for colour picture display
- H04N 9/44 Colour synchronisation
- H04N 9/64 Circuits for processing colour signals (H04N9/77 takes precedence; camera processing pipelines for processing colour signals H04N23/84)
