Abstract

Data intended to be displayed on a higher resolution display such as a non-interlaced display used as a computer monitor may be converted for display on a lower resolution display such as an interlaced display. The conversion may be done in a way that preserves the intended frame format while enhancing readability. For example, in one embodiment, the frames intended for non-interlaced display may be preserved in size for display in the same frame format on a lower resolution interlaced display. Local magnification may be selectively implemented for particular regions to enhance the readability of those regions. Upon selection, such local magnification may provide pixel loss and color corrections in addition to local magnification. In this way the frame format may be preserved while enhancing readability.

Claims

1. A method of displaying information on an lower resolution display comprising:

receiving data formatted for display on a higher resolution non-interlaced display at a first size;

selectively enlarge a portion of the data displayed on a lower resolution display;

converting data formatted for display at said first size on higher resolution non-interlaced display, for display on a lower resolution interlaced display;

locating high saturation colors which are sufficiently close to one another to result in color distortion; and

correcting for colors that do not convert correctly when switching between interlaced and non-interlaced displays.

2. The method of claim 1 including identifying regions of likely pixel loss.

3. The method of claim 2 including locating horizontal lines of less than a predetermined thickness and increasing the thickness of such lines.

4. The article of claim 1 including instructions that cause a processor based system to receive information from the user indicating a region to be selectively enlarged.

5. The method of claim 1 including selectively enlarging a portion of the information on the lower resolution display.

6. A processor based system comprising:

a processor; and

a memory coupled to said processor, said memory storing instructions that cause the processor to receive data formatted for display on a higher resolution non-interlaced display at a first size, selectively enlarge a portion of the data displayed on a lower resolution display, convert data formatted for display at said first size on higher resolution non-interlaced display, for display on a lower resolution interlaced display, locate high saturation colors which are sufficiently close to one another to result in color distortion, and correct for colors that do not convert correctly when switching between interlaced and non-interlaced displays.

7. The system of claim 6 wherein said processor is adapted to convert data formatted for display on a higher resolution, non-interlaced display for display on a lower resolution interlaced display.

8. The system of claim 6 including a remote control unit adapted to provide input signals for said processor.

9. The system of claim 6 including a television receiver coupled to said processor.

10. The system of claim 6 wherein said system is a set-top computer system.

11. A method of displaying information on an lower resolution display comprising:

receiving data formatted for display on a higher resolution non-interlaced display at a first size;

converting data formatted for display at said first size on higher resolution non-interlaced display, for display on a lower resolution interlaced display;

identifying areas of likely color distortion in converting from non-interlaced to interlaced display; and

locating high saturation colors which are sufficiently close to one another to result in color distortion.

12. A method of displaying information on an lower resolution display comprising:

receiving data formatted for display on a higher resolution non-interlaced display at a first size;

converting data formatted for display at said first size on higher resolution non-interlaced display, for display on a lower resolution interlaced display;

identifying regions of likely pixel loss; and

locating horizontal lines of less than a predetermined thickness and increasing the thickness of such lines.

13. An article comprising a medium for storing instructions that cause a processor based system to:

receive data formatted for a display on a higher resolution display;

selectively enlarge a portion of the data displayed on a lower resolution display;

convert data for display on a higher resolution non-interlaced display for display on a lower resolution interlaced display; and

correcting for colors that do not convert correctly when switching between interlaced and non-interlaced displays.
