Color video signal transmitting apparatus

摘要

A color video signal transmitting apparatus comprises first and second input terminals supplied in parallel with a time base compressed luminance signal and a first time base compressed line-sequential color difference signal which are obtained from one or a plurality of pickup elements of a television camera by changing an effective horizontal scanning period of the one or a plurality of pickup elements to a predetermined short period, a circuit for producing a second time base compressed line-sequential color difference signal by time base compressing the signal from the second input terminal, a circuit for obtaining a multiplexed signal of a second synchronizing signal having a predetermined width and being in phase with a first synchronizing signal from a third input terminal and a discriminating signal of every two regular horizontal scanning periods which is used to discriminate either one of two kinds of time base compressed color difference signals which make up the second time base compressed line-sequential color difference signal, to produce a multiplexed signal in which the second synchronizing signal and the discriminating signal are multiplexed, a circuit for obtaining a time-division-multiplexed signal by time-division-multiplexing the time base compressed color difference signals, the time base compressed luminance signal, and the multiplexed signal, and a circuit for transmitting the time-division-multiplexed signal to a transmitting path.
