ABSTRACT:
A system including an encoder for translating a standard color TV video signal to a buried subcarrier video signal for transmission, and a decoder for translating the received buried subcarrier video signal back to a standard video signal. A cross-hatch perturbation on screens of TV receivers using the decoded signal can result from the operation of comb filters, local oscillators and mixers in the system when there is an abrupt change in color information in adjacent horizontal lines. The perturbation is prevented by maintaining the respective outputs of the local oscillators in the encoder and the decoder at opposite phases.
