Abstract

A method of providing auxiliary data on a display includes receiving a video signal, extracting from the video signal auxiliary data, and storing the extracted auxiliary data. The method also includes extracting from the video signal a video image, and storing the extracted video image. The video image is manipulated to adjust either a horizontal dimension or a vertical dimension of the image and the manipulated video image is positioned on the display. The auxiliary data are also positioned on the display adjacent to the positioned video image.

Claims

1. A method of providing auxiliary data on a display, comprising the steps of:

(a) receiving a video signal;

(b) extracting from the video signal auxiliary data and storing the extracted auxiliary data;

(c) extracting from the video signal a video image, and storing the extracted video image;

(d) manipulating the video image to adjust a least one of a horizontal dimension and a vertical dimension;

(e) positioning the manipulated video image on the display; and

(f) positioning the auxiliary data on the display adjacent to the positioned video image.

2. The method of claim 1 in which

step (d) includes proportionately reducing the size of the video image in size in the horizontal dimension and in the vertical dimension;

step (e) includes positioning the reduced sized image to a side of the display; and

step (f) includes positioning the auxiliary data to another side of the display.

3. The method of claim 2 in which the reduced sized image is positioned on a top side of the display and the auxiliary data is positioned on a bottom side of the display.

4. The method of claim 2 in which the reduced sized image is positioned on a bottom side of the display and the auxiliary data is positioned on a top side of the display.

5. The method of claim 1 in which

step (a) includes receiving the video signal having a predetermined aspect ratio;

and

step (d) includes proportionately reducing the size of the video image to an aspect ratio substantially similar to the predetermined aspect ratio.

6. The method of claim 5 in which the predetermined aspect ratio is 4×

3.

7. The method of claim 1 in which

step (d) includes distorting the video image in the vertical dimension to reduce the video image in size;

step (e) includes positioning the distorted image to a side of the display; and

step (f) includes positioning the auxiliary data to another side of the display.

8. The method of claim 7 in which the distorted image is positioned on a top side of the display and the auxiliary data is positioned on a bottom side of the display.

9. The method of claim 7 in which the distorted image is positioned on a bottom side of the display and the auxiliary data is positioned on a top side of the display.

10. The method of claim 1 in which the display has a 4×

3 aspect ratio, and in which

step (a) includes receiving a video signal having a 16×

9 aspect ratio;

step (d) includes reducing the video image in the horizontal dimension to fit a horizontal dimension of the display, and proportionately reducing the video image in the vertical dimension to substantially maintain the 16×

9 aspect ratio of the video image;

step (e) includes positioning the video image on the display to one of (1) a top side of the display and (2) to a bottom side of the display; and

step (f) includes positioning the auxiliary data to an opposing respective bottom side of the display or top side of the display.

11. The method of claim 1 in which the display includes a 16×

9 aspect ratio, and in which

step (a) includes receiving a video signal having a 4×

3 aspect ratio;

step (d) includes enlarging the video image in the vertical dimension to fit a vertical dimension of the display, and proportionately enlarging the video image in the horizontal dimension to substantially maintain the 4×

3 aspect ratio of the video image;

step (e) includes positioning the video image on the display to one of (1) a left side of the display and (2) to a right side of the display; and

step (f) includes positioning the auxiliary data to an opposing respective right side of the display or left side of the display.

12. The method of claim 1 further including the steps of:

receiving a selection of an aspect ratio of the display;

receiving a selection of an aspect ratio of the received video image; and

step (d) includes manipulating the video image in size to occupy a first portion of the display; and

step (f) includes positioning the auxiliary data on a second portion of the display, in which the first and second portion are disposed side-by-side on the display.

13. The method of claim 12 further including the steps of:

receiving a selection of “

off-image”

for the display; and

step (f) includes positioning the auxiliary data in response to the selection of “

off-image”

.

14. A method of providing closed caption data on a display having a predetermined aspect ratio, comprising the steps of:

(a) receiving a video image and closed caption data;

(b) determining an aspect ratio of the received video image;

(c) shrinking the video image in a vertical dimension, if the determined aspect ratio of the received video image is substantially similar to the predetermined aspect ratio of the display;

(d) placing the video image at one of (1) a top portion of the display and (2) a bottom portion of the display; and

(e) positioning the closed caption data at an opposing respective bottom portion of the display or a top portion of the display.

15. The method of claim 14 including the step of:

receiving a selection of “

maintain aspect ratio”

; and

step (c) includes shrinking the video image in a horizontal dimension in addition to the vertical dimension, if “

maintain aspect ratio”

is selected.

16. A method of providing closed caption data on a display having a predetermined aspect ratio, comprising the steps of:

(a) receiving a video image and closed caption data;

(b) determining an aspect ratio of the received video image;

(c) determining a width dimension of the display and a width dimension of the video image, if the determined aspect ratio of the received video image is different than the predetermined aspect ratio of the display;

(d) resizing the video image in the width dimension to fit the width dimension of the display, if the determined width dimension of the video image is wider than the width dimension of the display;

(e) placing the resized video image at one of (1) a top portion of the display and (2) a bottom portion of the display; and

(f) positioning the closed caption data at an opposing respective bottom portion of the display or a top portion of the display.

17. A method of providing closed caption data on a display having a predetermined aspect ratio, comprising the steps of:

(a) receiving a video image and closed caption data;

(b) determining an aspect ratio of the received video image;

(c) determining a width dimension of the display and a width dimension of the video image, if the determined aspect ratio of the received video image is different than the predetermined aspect ratio of the display;

(d) resizing a height dimension the video image to fit a height dimension of the display, if the determined width dimension of the video image is smaller than the width dimension of the display;

(e) placing the resized video image at one of (1) a left portion of the display and (2) a right portion of the display; and

(f) positioning the closed caption data at an opposing respective right portion of the display or a left portion of the display.
