Abstract
Abstract An arrangement is described which multiplies the apparent horizontal resolution of color video display systems without requiring that the video memory in the system be multiplied equivalently. The arrangement may advantageously comprise any given number of bits per picture element for defining a displayable number of colors. One or more additional bit(s) per picture element is provided to convey positional information used for determining the location in a display at which the bits of color information are displayed. The additional memory requirement is limited to this one or more additional bits for each picture element in the display, instead of having the effect of multiplying the number of bits stored per PEL.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
162 words
A video display system for assembling data received from a data source and for displaying this data in the form of color images on a video display, the system comprising: means for receiving the data from the source; means for producing color image data having both horizontal and vertical coordinates and horizontal positional offset data representative of the data received; and means for assembling the color image data and the positional offset data such that the positional offset data in a first state provides an offset value for changing the value of the horizontal coordinate of the color image data, and in a second state does not provide an offset value for changing the value of the horizontal coordinate of the color image data, the assembling means providing the offset value to the value of the horizontal coordinate of the color image data by delaying in time the displaying of the color image data in the horizontal direction on the video display.
Claim 2
Dependent Claim
162 words
A video display system for assembling data received from a data source and for displaying this data in the form of color images on a video display, the system comprising: means for receiving the data from the source; means for producing color image data having both horizontal and vertical coordinates and horizontal positional offset data representative of the data received; and means for assembling the color image data and the positional offset data such that the positional offset data in a first state provides an offset value for changing the value of the horizontal coordinate of the color image data, and in a second state does not provide an offset value for changing the value of the horizontal coordinate of the color image data, the assembling means providing the offset value to the value of the horizontal coordinate of the color image data by delaying in time the displaying of the color image data in the horizontal direction on the video display.
Claim 3
Dependent Claim
34 words
The video display system of claim 1 further including means for storing the color image data and the positional offset data in memory; and means for accessing the memory for refreshing the video display.
Claim 4
Dependent Claim
32 words
The video display system of claim 1 wherein the positional offset data comprises one data bit for each of the plurality of horizontal and vertical coordinate positions displayable on the video display.
Claim 5
Dependent Claim
142 words
In a video display system for displaying color images on a video display, a display processing unit comprising: signal generating means for generating color image data having a plurality of both horizontal and vertical coordinates and horizontal positional offset data; and means for assembling the color image data and the positional offset data such that the positional offset data in a first state provides an offset value for changing the value of the horizontal coordinate of the color image data, and in a second state does not provide an offset value for changing the value of the horizontal coordinate of the color image data, the assembling means providing the offset value to the valve of the horizontal coordinate of the color image data by delaying in time the displaying of the color image data in the horizontal direction on the video display.
Claim 6
Dependent Claim
142 words
In a video display system for displaying color images on a video display, a display processing unit comprising: signal generating means for generating color image data having a plurality of both horizontal and vertical coordinates and horizontal positional offset data; and means for assembling the color image data and the positional offset data such that the positional offset data in a first state provides an offset value for changing the value of the horizontal coordinate of the color image data, and in a second state does not provide an offset value for changing the value of the horizontal coordinate of the color image data, the assembling means providing the offset value to the valve of the horizontal coordinate of the color image data by delaying in time the displaying of the color image data in the horizontal direction on the video display.
Claim 7
Dependent Claim
34 words
The display processing unit of claim 4 further including means for storing the color image data and the positional offset data in memory; and means for accessing the memory for refreshing the video display.
Claim 8
Dependent Claim
113 words
The video display system of claim 2 or 5 wherein the memory further comprises a first memory section for storing the color image data, a second memory section for storing the positional offset data, and a shift register for selectively receiving the color image data, the output of the register being responsive to the state of the positional offset data from the second memory section, the positional offset data while in the first state causing a time delay in the displaying of the color image data in the horizontal direction on the video display, and while in the second state not causing a time delay in the displaying of the color image data.
Claim 9
Dependent Claim
31 words
The video display system of claim 6 wherein the color image data for each of the plurality of horizontal and vertical coordinates comprise a picture element displayable on a video display.
Claim 10
Dependent Claim
34 words
The video display system of claim 7 wherein the time delay comprises one-half of a clock cycle, the clock cycle being the dwell time for the color image data at each horizontal coordinate position.
Claim 11
Dependent Claim
20 words
The video display system of claim 8 wherein the positional offset data comprises one data bit for each picture element.
Claim 12
Independent Claim
155 words
A method of assembling data received from a data source and for displaying this data in the form of color images on a video display, the method comprising the steps of: receiving the data from the course; producing color image data having both horizontal and vertical coordinates and horizontal positional offset data representative of the data received; and assembling the color image data and the positional offset data such that the positional offset data in a first state provides an offset value for changing the value of the horizontal coordinate of the color image data, and in a second state does not provide an offset value for changing the value of the horizontal coordinate of the color image data, the offset value being provided to the value of the horizontal coordinate of the color image data by delaying in time the displaying of the color image data in the horizontal direction on the video display.
Claim 13
Independent Claim
155 words
A method of assembling data received from a data source and for displaying this data in the form of color images on a video display, the method comprising the steps of: receiving the data from the course; producing color image data having both horizontal and vertical coordinates and horizontal positional offset data representative of the data received; and assembling the color image data and the positional offset data such that the positional offset data in a first state provides an offset value for changing the value of the horizontal coordinate of the color image data, and in a second state does not provide an offset value for changing the value of the horizontal coordinate of the color image data, the offset value being provided to the value of the horizontal coordinate of the color image data by delaying in time the displaying of the color image data in the horizontal direction on the video display.
Claim 14
Dependent Claim
34 words
The method as defined in claim 10 wherein the assembling step further includes: storing the color image data and the positional offset data in memory; and accessing the memory for refreshing the video display.
