ABSTRACT:
A television system (TV) with an interlaced display screen for displaying network application data. Pixel data elements representing network application data display are received in a non-interlaced mode. The received data is filtered to reduce sharp transitions in the display. The filtered data is provided in an interlaced format (i.e., only alternate lines of a frame) for display on the television display screen. The interlaced image display is combined with the television signal display by selecting one of them on point by point basis. Flicker is reduced substantially in the final display of network application data due to the filtering.
