Abstract
A system for providing a user controllable picture-in-picture formatted signal to a television is provided with a fast modem that interconnects the system with a computer network, such as the Internet. In order to allow a user to interact with the Internet, yet still enjoy video programming, the system has a picture-in-picture selection that a user controls to determine which video source (e.g., digital satellite signal, digital video disk signal, Internet graphics) will form the main picture displayed on the television, and which will form the picture-in-picture. A conventional television may be used with the system to display the signal, since it is already formatted in a picture-in-picture format at the output of the system.

13. A picture-in-picture (PIP) processor that receives video signals from a plurality of sources and selectively formats the video signals into a display signal having a format with a first one of the video signals forming a main picture and a second one of the video signals forming a picture-in-picture, the processor comprising:
-
a horizontal decimater that receives the video signal that is to form the picture-in-picture and horizontally decimates said video signal; a vertical decimater that receives the horizontally decimated video signal that is to form the picture-in-picture and vertically decimates said video signal; a selection arrangement that selects which of the video signals is horizontally and vertically decimated to form the picture-in-picture and which of the video signals forms the main picture; and an output at which the video signals forming the picture-in-picture and the main picture are generated as a single picture-in-picture signal. - View Dependent Claims (14, 15, 16, 17)

19. A system for providing a display signal to a TV receiver for on-screen display, comprising:
-
a first source of video signals; a second source of video signals; a picture-in-picture (PIP) processor coupled to the first and second sources and selectively formatting the first source video signals and the second source video signals to form a single display signal including therein said video signals from said first source and from said second source in PIP format, said system providing said single display signal in PIP format to said TV receiver for display, thereby eliminating a requirement for said TV set to have a PIP function for simultaneous display of said video signals from said first source and from said second source. - View Dependent Claims (20)
