ABSTRACT:
In a recording/reproducing apparatus for digital composite video signal, a phase sync circuit (110) for synchronizing color subcarrer phases, a sync/ID adding circuit (9), a sync/ID detecting circuit (12), a memory control circuit (13), a memory (14), and a phase relocating circuit (111), are provided for obtaining correct hues of the digital composite video signal when high-speed reproducing. When high-speed reproducing, the memory control circuit (13) is operated such that corresponding sampled signals in the memory (14) are stored as the same address with the same color subcarrier phase. As a result, a high image quality is achieved by the recording/reproducing apparatus even when high-speed reproducing with low manufacturing cost.
