  • Patent number: 5424849
    Abstract: The video signal reproduction apparatus having two kinds of equalizing circuits to correct the level of a frequency-modulated luminance signal, that is, a first equalizing circuit which raises the level of the upper sideband range of the frequency-modulated luminance signal and a second equalizing circuit which raises the level of the lower sideband range of the frequency-modulated luminance signal, so that the part of the frequency-modulated luminance signal where a horizontal synchronizing signal is not modulated is processed by the first equalizing circuit, while the part of the frequency-modulated luminance signal where a horizontal synchronizing signal is modulated is processed by the second equalizing circuit.

  • Patent number: 4562493
    Abstract: A magnetic video recording apparatus for intermittent recording comprises a magnetic tape driving circuit (30), a video signal recording circuit (20), a control circuit (40) and a recording start instructing circuit (60). The magnetic tape driving circuit (30) makes a magnetic tape (1) travel at a predetermined speed while it is enabled. The video signal recording circuit (20) records a video signal (VS) in the magnetic tape (1) in a predetermined format. The recording start instructing circuit (60) provides intermittently a recording start signal (RS). The control circuit (40) enables the magnetic tape driving circuit (30) in response to the recording start signal (RS), enables the video signal recording circuit (20) for a predetermined period of time and then disables the magnetic tape driving circuit (30). A tape pattern thus recorded in the magnetic tape (1) does not differ from that in an ordinary video tape recorder.
