Abstract

A television arrangement generates signals from independent pairs of adjacent lines. The signals are separately summed and differenced to produce S and .DELTA. signals. The S signal is representative of the luminance of a scan between the original scans, and the .DELTA. represents vertical resolution. The signals are transmitted to a monitor for generating a high-vertical-resolution picture. Where the display is a color TV receiver, the .DELTA. signal may be buried within the chroma channel by frequency interleaving with the .DELTA. signal occuring only in locations representing high-frequency vertical information. The buried .DELTA. signal is invisible on a conventional receiver. Other independent data may be coupled through the chroma channel by frequency interleaving.
