• H04N 5/9201
• H04N 5/921 by recording or reproducing the baseband signal
• H04N 5/923 using preemphasis of the signal before modulation and deemphasis of the signal after demodulation
• H04N 5/926 by pulse code modulation (H04N5/919 takes precedence)
• H04N 5/928 the sound signal being pulse code modulated and recorded in time division multiplex with the modulated video signal
