  • Patent number: 6833874
    Abstract: A ticker tape PiP system that provides for viewing the ticker tape image portion from one image signal (e.g., a ticker tape image portion of a television image signal), while viewing at least a portion of an image from a different image signal (i.e., a standard television program image). The ticker tape PiP system includes an image display device, a first tuner and a second tuner. The first and second tuners are configured to receive first and second image signals and to output corresponding first and second video signals, respectively. The ticker tape PiP system also includes a video switching subsystem for receiving the first and second video signals and for selectively switching an output to the image display device between (i) an RGB formatted display signal derived from the first video signal and (ii) an RGB formatted display signal derived from the second video signal that corresponds only to a ticker tape image portion of the second video signal.
