## Abstract

A system for displaying information including a central processing unit, the central processing unit receiving real-time image data consisting of at least one of waveform and picture data, and web input data and producing a first graphics layer of web data, a second graphics layer of graticule data, and a third graphics layer of real-time data, a memory connected to the central processing unit to store the first, second and third graphics layers, a graphics processor to retrieve the first, second and third graphics layers from the memory and to generate a display window, and a display device to display the display window.

## Claims

### Claim 1

A system for displaying information, comprising:
a central processing unit, the central processing unit receiving real-time image data consisting of at least one of waveform and picture data, and web input data and producing a first graphics layer of web data, a second graphics layer of graticule data, and a third graphics layer of real-time data;
a memory connected to the central processing unit to store the first, second and third graphics layers;
a graphics processor to retrieve the first, second and third graphics layers from the memory and to generate a display window; and
a display device to display the display window.

### Claim 2 (depends on 1)

The system of claim 1, wherein the graphics processor comprises an array of texture processing elements.

### Claim 3 (depends on 1)

The system of claim 1, wherein the central processing unit receives a frame data signal.

### Claim 4 (depends on 3)

The system of claim 3, wherein the frame data signal consists of at least one of a frame rate, frame number and a scan type.

### Claim 5 (depends on 1)

The system of claim 1, further comprising a web developer front end connected to the central processing unit.

### Claim 6 (depends on 1)

The system of claim 1, wherein the graphics processing unit further comprises a fragment shader.

### Claim 7 (depends on 1)

The system of claim 1, wherein the graphics processing unit further comprises a rasterizer.

### Claim 8

A method of combining different types of display data, comprising:
receiving, at a central processing unit, web data and real-time image data consisting of at least one of waveform and picture data;
generating, by the central processing unit, a first graphics layer of web data from the web data, a second graphics layer of graticule data; and a third layer of real-time data;
storing the first, second, and third graphics layers in memory;
retrieving, with a graphics processing unit, the first, second and third graphics layers from memory; and
producing, with the graphics processing unit, a composite display window of the first, second and third graphics layers.

### Claim 9 (depends on 8)

The method of claim 8, wherein receiving the web based user interface data comprises receiving user interface data from a web based user interface.

### Claim 10 (depends on 8)

The method of claim 8, wherein receiving the real-time image data comprises receiving real-time image data from a piece of monitoring equipment.

### Claim 11 (depends on 8)

The method of claim 8, wherein producing the composite display window includes performing frame rate conversion.

### Claim 12 (depends on 8)

The method of claim 8, wherein producing the composite display window includes rasterizing the display window.

### Claim 13 (depends on 8)

The method of claim 8, further comprising:
receiving the real-time data at the central processing unit;
receiving a frame data signal at the central processing unit;
loading an element of a two-dimensional texture array in the graphics processing unit with the graphics data;
making an index identifying the element available to the graphics processing unit; and
sampling, with the graphics processing unit, the element identifying by the index and passing it to a rasterizing.

### Claim 14 (depends on 13)

The method of claim 13, wherein frame data signal identifies the real-time data as progressive scan data.

### Claim 15 (depends on 14)

The method of claim 14, wherein sampling comprises sampling the data with the fragment shader.

### Claim 16 (depends on 13)

The method of claim 13, wherein the frame data signal identifies the real-time data as interlaced scan data.

### Claim 17 (depends on 16)

The method of claim 16, wherein making an index identifying the element available further comprises determining if the index is even or odd.

### Claim 18 (depends on 17)

The method of claim 17, wherein the sampling repeats sampling of an element if the index is odd.

### Claim 19 (depends on 17)

The method of claim 17, wherein the sampling samples the successive element if the index is even.
