ABSTRACT:
A television receiver processes a television signal representing a letterbox image display format with an image region, and a bar region containing "helper" information to help convert from interlaced to progressive scanning. An image signal processing path contains a motion detector and switch for determining whether a video processor receives image information (in the presence of motion), or field repeated information (in the absence of motion). Another motion detector associated with helper signal processing exhibits a narrower motion spreading characteristic than the motion detector in the image path, and determines when the helper signal is coupled to the image path.
