ABSTRACT:
A system for handling special television video features digitally. The system receives incoming broadcast video into a switch (106). The switch allows the viewer to select a main channel and at least one auxiliary channel for viewing as a special feature, if the viewer does not want to view only the main channel for that particular special feature. The main video channel data is processed by a scan converter (216) to convert it from interlaced to progressive scan. A logic device (212) handles the auxiliary channel data to format it into the selected special feature and inputs that data to the scan converter (216) such that the special feature appears in the proper place relative to the main channel image.
