发明名称 Video-signal time-axis correction apparatus
摘要 A time-axis of a digital video-signal is converted to a standard time-axis by changing a clock signal contained therein to a standard clock signal and by locking phases of input synchronizing signals contained therein onto the phase of the standard clock signal through a memory for alternately writing and reading the digital video signal at one half of the period of the standard clock signal. As a result, the time-axis correction of the digital video signal is efficiently effected through the memory having a small capacity and a simplified controlling arrangement.
