Video display system
First Claim
1. A video display system comprised of:
- a video processor having at least a first computer video input port and a second, NTSC video input port and a video signal output port, capable of being operatively coupled to a fixed-pixel array video display device; and
a memory storage device, operatively coupled to the video processor and storing program instructions which, when executed cause the video processor to format video input signals at both ports, into a single VESA compliant video signal that is sent to a fixed pixel video display device where upon video input signals are scaled to fit to video window areas within the fixed pixel array display device.

Abstract
A fixed-pixel array display system and video processor merge multiple video streams, each from a separate computer or non-VESA compliant video source, into a single VESA-compliant video stream. The separate video streams are re-formatted by the video processor to fit within its own display area. The display areas are separately determined by the processor. Arrays along the edges of the fixed-pixel array display device detect a tactile contact with the display screen. The coordinates of a tactile contact are read by the video processor and correlated to a sector of the display device where a video image is displayed. The location of the tactile contact is sent to the video source as an input to its graphical user interface. Separate computers or other video sources with graphical user interfaces can be controlled from the single display device using the touch sensitive input screen.

6. A video display system comprised of:
-
a VESA-compliant, fixed-pixel array display device said display device capable of displaying multiple video images in separate display areas of the display device, each video image displayed on the display device being generated from a corresponding video signal from a corresponding video source;
a video processor, the video processor having a first video input port that is capable of receiving a first format video signal and, a second video input port that is capable of receiving a second format video signal, at least one of said first and second video signal formats capable of being a non-VESA compliant format, said video processor having a VESA-compliant video signal output port operatively coupled to the video display device from which a VESA-compliant video output signal is output; and
memory, operatively coupled to the video processor and storing program instructions which, when executed cause the video processor to process at least one of;
the first video signal and the second video signal received at the second video input, into a single format, such that a video image produced on the display device by the first video signal and a video image produced on the display device by the second video signal, are of substantially the same size on, and in different sections of, the display device. - View Dependent Claims (7, 8, 9, 10, 11)

12. A video display system comprised of:
-
an input/output (I/O) device having a fixed-pixel array display device that is VESA compliant and capable of displaying one or more video images, each of the video images being generated by a corresponding video signal, each video image being displayed in its own area of the fixed-pixel array display device said I/O device also having an optical touch-sensor by which the location of a contact with the display device is determinable;
a processor having a first video input port that is capable of receiving a first video signal from a first video source, a second video input port that is capable of receiving a second video signal from a second video source, and a tactile sense input coupled to the input/output device and receiving signals from which the location of a tactile contact with the input/output device can be determined, said processor having a video signal output port operatively coupled to the fixed pixel array video display device; and
memory, operatively coupled to the processor and storing program instructions which, when executed cause the processor to process at least one of;
the first video signal and the second video signal into a single VESA-compliant format, such that a video image produced on the fixed pixel array display device by the first video signal and a video image produced on the fixed pixel array display device by the second video signal, are in different sections of the display device, the program instructions further causing the processor to read signals indicative of a tactile contact with the display device and to display on the I/O device, an indication that the tactile contact was detected. - View Dependent Claims (13, 14)

15. A video display system comprised of:
-
a display device capable of displaying one or more video images, each generated by a corresponding video signal, each video image being displayed in its own area of the display device, said display device also having an optical tactile contact sensor by which the location of a tactile contact with the touch-sensitive input screen is determinable;
a Crestron video processor operatively coupled to the display device, the video processor capable of receiving a first video signal from a first non-VESA compliant source, a second video input port that is capable of receiving a second, VESA-compliant video signal from a second video source, and a tactile sense input coupled to the display device and receiving signals indicative of the location of a tactile contact with the display device, said processor having a video signal output port operatively coupled to the display device; and
memory, operatively coupled to the Crestron video processor and storing program instructions which, when executed cause the processor to process at least one of;
the first video signal and the second video signal into a single VESA-compliant format, such that a video image produced on the display device by the first video signal and a video image produced on the display device by the second video signal, are of substantially the same size on, and in different sections of the display device, the program instructions further causing the processor to read signals indicative of tactile contact with the display device and to display on the display device, an indication of the tactile contact to electronically simulate the action of drawing on the screen with a marker or to manipulate the functions of the attached computers. - View Dependent Claims (16, 17)

18. A method of displaying multiple video images on a single display device comprise of the steps of:
-
receiving a plurality of video signals at a video processor, each of the video signals being capable of being processed to generate an image on a display device such that a first one of the video signals will generate an image of a first size on a display device and a second one of the video signals will generate an image of a second size on a display device; and
processing at least one of the video signals after its receipt so that when the first and second video signals are processed, they each generate images of the same size on a display device. - View Dependent Claims (19, 20)
