    • A video signal recording apparatus is provided with first and second channels for transmitting an input video signal. The first channel has a line memory for conducting a 1H delay on data and a time-base-extension line memory for conducting time base extension on the data with the 1H delay. The data subjected to the time base extension undergoes D/A conversion to be an output of the first channel. On the other hand, the second channel does not have a line memory for a 1H delay, and the video signal without delay is subjected to time base extension and undergoes D/A conversion to be an output of the second channel. In the arrangement, odd lines and even lines respectively contained in adjoining two frames in each channel are reversed such that in a certain frame, odd lines of the input video signal are transmitted through the first channel with even lines through the second channel. In the next frame, even lines are transmitted through the first channel with odd lines through the second channel. Thus, influences on the reproduced picture due to the difference of circuit characteristics is averaged and the perception to unevenness of color or brightness is avoided.
    • 视频信号记录装置具有用于发送输入视频信号的第一和第二信道。 第一通道具有用于在数据上进行1H延迟的行存储器和用于对1H延迟的数据进行时基扩展的时基扩展线存储器。 经过时基扩展的数据经历D / A转换为第一通道的输出。 另一方面,第二通道不具有用于1H延迟的行存储器,并且没有延迟的视频信号经受时基扩展,并且经历D / A转换为第二通道的输出。 在这种布置中,分别包含在每个通道中的相邻两个帧中的奇数行和偶数行被反转,使得在某个帧中,输入视频信号的奇数行通过第二通道的偶数行通过第一通道传输。 在下一帧中,偶数行通过第二通道以奇数行通过第一通道传输。 因此,由于电路特性的差异对对再现图像的影响被平均,并且避免了对颜色或亮度的不均匀性的感知。
