    摘要: To transmit color video information from one point to another within a color television studio complex, particularly for distribution of source signals which are intended to be processed in a digital mode at another location in the studio, the information is transmitted in form of a color television signal comprising a luminance component having a given frequency range and a carrier frequency chrominance component having a frequency range outside that of the luminance component, the chrominance component simultaneously obtaining the full color information for the luminance component. The selected mode permits the ready separation of the luminance and chrominance components without perceptible quality losses, and recording and cutting processing.

    摘要: A comb filter filters the luminance signal and a difference signal indicative of the difference in signal content between two sequential lines. A low-pass filter furnishes a low frequency luminance signal having only the low frequency components of the luminance signal. The low frequency signal is applied to a horizontal aperture correction circuit which furnishes substitute high frequency signals. The low frequency luminance signal and the substitute high frequency signals are applied to one input of a fade-in fade-out circuit whose other input receives the luminance signal. The ratio of signals at the output of the fade-in fade-out circuit is controlled by a correlation signal derived from the difference signal. In the digital embodiment, the fade-in fade-out circuit receives the luminance signal and the substitute high frequency signals only and the low frequency luminance signal is added to the output of the fade-in fade-out circuit. The chrominance signals are derived by synchronous detection from the difference signal.

    摘要: An apparatus for delaying a signal n period lengths by the use of two shift registers which have capacities less than n but which have a total capacity greater than n. The signal to be delayed is fed to a first shift register until that shift register is full. The signal is then fed to a second shift register. Timing signals which control the shift registers' receipt of information are properly blanked in order to allow this result. When n bits of information have been recorded by the shift registers, the first shift register is again inputted causing an output which corresponds to the first data bits of the signal. While the first shift register is receiving and outputting the second cycle of information a pre-determined number of data bits are fed to the second shift register to fill the register. This cycle is repeated resulting in the storage of n data bits by a plurality of shift registers which each have a capacity less than n which have a total capacity greater than n.
