ABSTRACT:
A widescreen television signal having left side, right side and center panel information is converted into a signal compatible with a standard television system, such as NTSC. In the compatible signal, center panel information is expanded to occupy the standard display region seen by a viewer, side panel low frequency information is compressed into the horizontal overscan region, and side panel high frequency information modulates an alternative subcarrier other than the chrominance subcarrier.
