Abstract

According to the present invention, there is provided a method, system and program storage device for displaying textual information associated with a defined video object in video data on a video display device, comprising: sampling a video object plane to determine whether the video object is in the video object plane for displaying the video object on the video display device; updating a location of the video object in the video object plane as the video object moves during display of the video data on the video display device; determining whether a pointing device is over the updated location of the video object; and displaying the textual information associated with the video object on the video display device for a predetermined period of time.

Claims

1. A method for displaying textual information associated with a video object embedded in moving images in a received video stream, the method comprising:

determining whether the video object is a type of video object for which textual information is provided for display therewith, by determining whether a video object type code in the received video stream which is associated with the video object, is of a specified type;

retrieving the textual information embedded in the received video stream in response to the determining that the video object type code is of the specified type;

displaying the video object on a display, wherein a location of the video object on the display is selectable by a user by controlling a position of a cursor associated with a pointing device;

determining whether the user has selected the video object using the pointing device;

displaying the retrieved textual information embedded in the received video stream on the display, together with the video object, when it is determined that the user has selected the video object.

2. The method of claim 1, wherein:

the video object exists at a plurality of video object planes in the video stream at a plurality of successive time positions in a time continuum;

the method further comprising sampling the video object from the received video stream at the plurality of video object planes to determine respective updated locations of the video object in the video object planes.

3. The method of claim 1, further comprising:

executing a timer to determine a predetermined period of time for displaying the retrieved textual information.

4. The method of claim 1, further comprising:

determining whether a button on the pointing device is depressed;

wherein the retrieved textual information is displayed when the button on the pointing device is depressed and the cursor is over the location of the video object.

5. The method of claim 2, wherein the video stream is provided according to an MPEG-4 standard.

6. The method of claim 1, wherein the video object planes (VOPs) comprise at least one of intra coded VOPs, predictive coded VOPs, and bidirectionally-predictive coded VOPs.

7. The method for displaying textual information according to claim 1, wherein the sampling the video object comprises using motion vectors from the received video stream to determine the respective updated locations of the video object in the video object planes.

8. A system for displaying textual information associated with a video object embedded in moving images in a received video stream, the system comprising:

a display for displaying the video object, wherein a location of the video object on the display is selectable by a user by controlling a position of a cursor associated with a pointing device; and

a processor for;

(a) determining whether the user has selected the video object using the pointing device;

(b) determining whether the video object is a type of video object for which textual information is provided for display therewith, by determining whether a video object type code in the received video stream which is associated with the selected video object, is of a specified type;

(c) retrieving the textual information embedded in the received video stream in response to the determining that the video object type code is of the specified type;

(d) determining whether the user has selected the video object using the pointing device; and

(e) directing a displaying of the retrieved textual information embedded in the received video stream on the display, together with the video object, when it is determined that the user has selected the video object.

9. The system of claim 8, wherein:

the video object exists at a plurality of video object planes in the video stream at a plurality of successive time positions in a time continuum, and the decoder samples the video object from the received video stream at the plurality of video object planes to determine respective updated locations of the video object in the video object planes.

10. The system of claim 8, further comprising:

means for executing a timer to determine a predetermined period of time for displaying the retrieved textual information.

11. The system of claim 8, further comprising:

means for determining whether a button on the pointing device is depressed;

wherein the retrieved textual information is displayed by the display when the button on the pointing device is depressed and the cursor is over the location of the video object.

12. The system of claim 9, wherein the video stream is provided according to an MPEG-4 standard.

13. The system of claim 9, wherein the video object planes (VOPs) comprise at least one of intra coded VOPs, predictive coded VOPs, and bidirectionally-predictive coded VOPs.

14. The system for displaying textual information according to claim 9, wherein the decoder samples the video object comprises using motion vectors from the received video stream to determine the respective updated locations of the video object in the video object planes.

15. A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform a method for displaying textual information associated with a video object embedded in moving images in a received video stream, the method comprising:

determining whether the video object is a type of video object for which textual information is provided for display therewith, by determining whether a video object type code in the received video stream which is associated with the video object, is of a specified type;

retrieving the textual information embedded in the received video stream in response to the determining that the video object type code is of the specified type;

displaying the video object on a display, wherein a location of the video object on the display is selectable by a user by controlling a position of a cursor associated with a pointing device;

determining whether the user has selected the video object using the pointing device; and

displaying the retrieved textual information embedded in the received video stream on the display, together with the video object, when it is determined that the user has selected the video object.

16. The program storage device of claim 15, wherein:

the video object exists at a plurality of video object planes in the video stream at a plurality of successive time positions in a time continuum;

the method further comprising sampling the video object from the received video stream at the plurality of video object planes to determine respective updated locations of the video object in the video object planes.

17. The program storage device of claim 15, wherein the method further comprises:

executing a timer to determine a predetermined period of time for displaying the retrieved textual information.

18. The program storage device of claim 16, wherein the video object planes (VOPs) comprise at least one of intra coded VOPs, predictive coded VOPs, and bidirectionally-predictive coded VOPs.

19. The program storage device for displaying textual information according to claim 16, wherein the sampling the video object comprises using motion vectors from the received video stream to determine the respective updated locations of the video object in the video object planes.
