ABSTRACT:
Recording and reproducing a television signal with a DC shifter prevents compression distortion of a PAL plus television signal. The PAL plus television signal includes a vertical resolution signal for enhancing vertical resolution which vertical resolution signal is included in the same compression blocks as some of the component video signals. Such compression blocks are shifted to a DC set up value so that the signals within those compression blocks do not have varying DC offsets which otherwise could result in compression distortion. Similarly, upon reproduction, the DC set up value is removed after decompression and the original television signal is restored with complete vertical resolution.
