Japanese Patent JP2733957
Kind Code:
B2
Abstract:
A video signal reproducing apparatus in a system for fast locking a reproduced image obtained from a recording medium where a time code signal is also recorded. The apparatus includes a memory for storing plural frames of the video signal, a time code comparator for generating a control signal by comparing the time code signal obtained from the recording medium with an external reference time code signal, and a reading controller for controlling the memory and selectively reading one frame of the video signal therefrom in accordance with the control signal so that the time code signal corresponding to the video signal selectively read by the reading controller coincides with the reference time code signal. The video signal reproduced by the apparatus placed in a standby state at a preroll point can be raised to a stable normal reproduction state within a relatively short time. Such video signals retained in synchronism are sequentially stored in the frame memories and, after being delayed per frame, the video signal coincident with the external time code signal is selected, whereby the lock-in operation can be quickly completed to consequently reduce the amount of preroll.
