    • An apparatus for correcting a time base of a video signal generates a clock which is phase-synchronized with a sync. signal of the video signal and has the same frequency. In a special reproducing mode, the apparatus switches an output level of a phase comparator, which phase-compares the sync. signal and the clock to a predetermined level, which is applied to a controlled oscillator and resets a frequency divider which frequency-divides the output of the controlled oscillator, in accordance with the sync. signal to produce the video signal which can be visually recognized even in the special reproducing mode. The apparatus samples and holds the output level of the phase comparator when the video signal drops out and resets the frequency divider which produces the clock by frequency-dividing the output of the controlled oscillator, when the dropout is recovered so that a video signal of high quality is produced immediately after the recovery of the dropout of the video signal.
    • 用于校正视频信号的时基的装置产生与同步相位同步的时钟。 视频信号的信号并具有相同的频率。 在特殊再现模式中,该装置切换相位比较器的输出电平,该相位比较器进行相位比较同步。 信号和时钟到预定电平,其被施加到受控振荡器并且根据同步来复位频率划分受控振荡器的输出的分频器。 信号以产生即使在特殊再现模式下也可视觉识别的视频信号。 当视频信号丢失时,该装置采样并保持相位比较器的输出电平,并且通过对受控振荡器的输出进行分频来复位产生时钟的分频器,当压降恢复时,视频信号为高电平 在恢复视频信号的丢失之后立即产生质量。

    • A time base correcting device inputs a video signal including a sync. signal and a burst signal, produces an error signal representing a phase difference between a clock signal synchronized with the sync. signal and the burst signal, writes the video signal into the memory in synchronism with the clock signal having a phase thereof adjusted in accordance with the error signal, produces an interpolation signal to interpolate a plurality of adjacent error signals along a time base and controls the readout from the memory by the error signals and the interpolation signal. In this manner, it attains time base correction, particularly velocity error correction with high accuracy.
    • 时基校正装置输入包括同步的视频信号。 信号和突发信号产生表示与同步同步的时钟信号之间的相位差的误差信号。 信号和突发信号,将视频信号与具有根据误差信号调整的相位的时钟信号同步地写入存储器,产生内插信号,以沿着时基内插多个相邻的误差信号,并且控制 通过误差信号和插值信号从存储器读出。 以这种方式,可以实现时基校正,特别是高精度的速度误差校正。
