ABSTRACT:
A MUSE signal recording/reproducing apparatus for converting a MUSE signal into a digital signal and for recording/reproducing the same, including an HDVTR, a signal processing device, and a control device for controlling the HDVTR and the signal processing device. The HDVTR is a device capable of recording/reproducing effective lines and effective picture elements of a high definition television signal. The signal processing device performs A/D conversion and multiplex processing of two synchronizing MUSE signals to convert the same into frequency double that of a MUSE signal, and further performs rate conversion corresponding to recording frequency and phase of the HDVTR. The HDVTR records the rate-converted data.
