    摘要: A video signal is serially enclosed for transmission in PCM form during synchronizing level intervals and encoded in a run length limited NRZ form during non-synchronizing level intervals, each PCM word being selected from minimum and maximum disallowed states of the NRZ code. In a decoder, a first detector responds only to the presence of the PCM code for synchronizing a second detector with response to both the NRZ and PCM coded portions of the encoded video signal to provide a decoded video output signal whereby the PCM portion of the signal conveys both decoder timing information and information as to a specific level of the video signal.

    摘要: A color encoding filter for use with a discrete photosensor pickup device has vertical stripes. The stripes occur in repeating cycles of color order, with the ratio of the width of a cycle to the width of a photosensor being a non-integer. This results in wider bandwidth in a luminance signal.The resulting pickup device output signal comprises a double sideband suppressed carrier signal having subcarriers conveying the chroma information. Both subcarriers can be demodulated, however demodulating only the upper sideband reduces biasing.
