Abstract
A video signal reproducing apparatus for reproducing a video signal from a recording medium includes a rotary head arranged to periodically trace the recording medium and reproduce the recorded video signal, a memory arranged to receive the video signal reproduced by the rotary head, memory control circuitry for controlling writing into and reading from the memory, a rotation controller for controlling rotation of the rotary head; and mode setting circuitry for setting the apparatus into one of a plurality of modes including first and second still picture reproduction modes. In both modes, stored signals are repetitively read from the memory with reading address resetting occurring in the course thereof. In the first mode, which involves short term reproduction, the rotary head is caused to rotate and the resetting is dependent of detection of phase detection of the rotary head. In the second mode, which involves long term reproduction, rotation of the rotary head is discontinued and resetting is attained without dependence on phase detection.
