ABSTRACT:
An apparatus and method are provided for encoding and decoding video signals on a conventional magnetic recording medium in a manner whereby the decoded video signal includes an improved chrominance characteristic. The improved chrominance characteristic is provided by encoding the conventional luminance and chrominance information signals on a first track of the information recording medium for the odd alternate fields and a modified luminance information signal and a select separate color component signal on a second track of the information recording medium. The signal recorded on the first track of the recording medium may be decoded in a conventional manner to provide video signals of limited chrominance video bandwidth or, alternatively, both tracks of the recording medium may be decoded in the manner of this invention to provide an improved chrominance characteristic video signal.
