Transmission system for color television signal
专利汇可以提供Transmission system for color television signal专利检索，专利查询，专利分析的服务。并且PURPOSE:To eliminate a color blurring on a screen by performing time axis compressing multiplex operation after superposing AC signals having the same waveform upon a luminance signal and chrominance signal and by controlling the phase of the luminance signal or chrominance signal in reproduction. CONSTITUTION:A luminance signal is inputted to terminal 1 and a chrominance signal to terminal 2, respectively. Then, AC signal generator 3 sends an AC signal with waveform (c) to adders 4 and 5, which add it to the luminance signal and chrominance signal, respectively. The output of adder 5 is sent to time axis compressing circuit 6 to compress its time axis. Chrominance-signal/luminance multiplexing circuit 8 multiplexes the outputs of adder 4 and circuit 6 to outut waveform (f) to terminal 10. This output signal is supplied via terminal 11 to chrominance- signal/luminance-signal separating circuit 12, which separates the input into luminance signal (h) and the chrominance signal. The chrominance signal has the time axis expanded by time-axis expanding circuit 13. This signal and signal (h) are supplied to relative gain detecting circuit 15 and relative delay detecting circuit 16 to detect the amplitude and phase shift and by the outputs of circuits 15 and 16, circuit 13 and 14 exercise control to eliminate the amplitude difference and phase difference between the luminance signal and chrominance signal.，下面是Transmission system for color television signal专利的具体信息内容。
