Claims
- 1. A video cassette recorder with a television set comprising:a recording/reproducing unit for generating a recording signal based on a video signal fed from a tuner unit and outputting the generated recording signal to a rotary head at a recording time and for generating a video signal based on a reproduced signal output from said rotary head and outputting the generated video signal at a reproducing time; and a video signal processing unit for generating a primary color chrominance signal from the same video signal as the video signal fed into said recording/reproducing unit at the recording time and for generating a primary color chrominance signal from the video signal generated by said recording/reproducing unit at the reproducing time, wherein said recording/reproducing unit includes an oscillation circuit for executing oscillation phase-synchronized with a burst signal of the video signal fed from said tuner unit at an operation time except during a reproducing operation and for oscillating a reference signal used as a reference for the burst signal, and further comprising an impedance conversion circuit arranged to receive an output of said oscillation circuit that has been phase-corrected, convert the phase-corrected output of the oscillation circuit into a low-impedance output signal, and supply the low impedance output signal to said video signal processing unit as a reference subcarrier at the reproducing time.
- 2. The video cassette recorder with a television set as claimed in claim 1, further comprising a phase correction circuit connected between the oscillation circuit and said impedance conversion circuit for correcting a phase of the reference subcarrier, wherein a phase correction amount of said phase correction circuit is a phase difference between an output phase of said oscillation circuit and a required phase of the reference subcarrier, whereby said phase correction amount is different during a reproducing operation than it is during other operation times.
- 3. The video cassette recorder with a television set as claimed in claim 1, wherein said impedance conversion circuit is an emitter-follower circuit.
