Each element of the signal waveform can be altered: Horizontal and Vertical frequencies, Level, Phase, and Subcarrierfrequency.
每个元素的信号波形可以改变：横向和纵向的频率，水平，阶段，副载波频率。

Color synchronous signal is setup to resume subcarrier color signal as same frequency and phase in receive end, which is suppressed in send end.
色同步信号是为了在接收端恢复与发送端被抑制掉的色副载波同频同相的载波而设置的。

The principle and method for calibrating the frequency by means of colour subcarrier signal of broadcast TV are introduced in detail, and the corresponding measurement accuracy is given in this paper.
