Abstract

Metadata for one or more highlights of a video stream may be extracted from one or more card images embedded in the video stream. The highlights may be segments of the video stream, such as a broadcast of a sporting event, that are of particular interest. According to one method, video frames of the video stream are stored. One or more information cards embedded in a decoded video frame may be detected by analyzing one or more predetermined video frame regions. Image segmentation, edge detection, and/or closed contour identification may then be performed on identified video frame region(s). Further processing may include obtaining a minimum rectangular perimeter area enclosing all remaining segments, which may then be further processed to determine precise boundaries of information card(s). The card image(s) may be analyzed to obtain metadata, which may be stored in association with at least one of the video frames.

Claims (52)

1. A computer-implemented method for extracting metadata from a video stream, the computer-implemented method comprising:

receiving, by one or more processors, a video stream that includes a video frame;

selecting, by the one or more processors, a video frame region that forms a portion of the video frame;

identifying, by the one or more processors, a card image embedded in the video frame;

extracting, by the one or more processors, the card image from the video frame;

generating, by the one or more processors, metadata based on the extracted card image;

selecting, by the one or more processors, a metadata subset based on one or more user preferences; and

outputting, by the one or more processors, the video frame and the selected metadata subset to a display.

2. The computer-implemented method of claim 1 , wherein the video stream corresponds to a broadcast of a sporting event.

3. The computer-implemented method of claim 2 , wherein the video frame corresponds to a highlight of the broadcast.

4. The computer-implemented method of claim 3 , wherein the metadata corresponds to a status of the sporting event during the highlight.

5. The computer-implemented method of claim 3 , the computer-implemented method further comprising:

outputting, by the one or more processors, the metadata subset during viewing of the highlight.

6. The computer-implemented method of claim 1 , wherein the selecting the video frame region comprises cropping the video frame to isolate the video frame region.

7. The computer-implemented method of claim 1 , wherein the selecting the video frame region comprises:

determining, by the one or more processors, whether a location of the card image is known;

based on determining that the location of the card image is known, selecting, by the one or more processors, the portion of the video frame from the known location as the video frame region; and

based on determining that the location of the card image is not known, sequentially processing, by the one or more processors, a plurality of regions of the video frame to identify the video frame region.

8. A computer system for extracting metadata from a video stream, the computer system comprising:

a processor; and

a non-transitory storage medium storing computer program instructions, that when executed by the processor cause the computer system to perform operations comprising:

receiving a video stream that includes a video frame;

selecting a video frame region that forms a portion of the video frame;

identifying a card image embedded in the video frame;

extracting the card image from the video frame;

generating metadata based on the extracted card image;

selecting a metadata subset based on one or more user preferences; and

outputting the video frame and the selected metadata subset to a display.

9. The computer system of claim 8 , wherein the video stream corresponds to a broadcast of a sporting event.

10. The computer system of claim 9 , wherein the video frame corresponds to a highlight of the broadcast.

11. The computer system of claim 10 , wherein the metadata corresponds to a status of the sporting event during the highlight.

12. The computer system of claim 10 , the operations further comprising:

outputting the metadata subset during viewing of the highlight.

13. The computer system of claim 8 , wherein the selecting the video frame region comprises cropping the video frame to isolate the video frame region.

14. The computer system of claim 8 , wherein the selecting the video frame region comprises:

determining whether a location of the card image is known;

based on determining that the location of the card image is known, selecting the portion of the video frame from the known location as the video frame region; and

based on determining that the location of the card image is not known, sequentially processing a plurality of regions of the video frame to identify the video frame region.

15. A non-transitory storage medium storing computer program instructions that when executed by a processor perform operations comprising:

receiving a video stream that includes a video frame;

selecting a video frame region that forms a portion of the video frame;

identifying a card image embedded in the video frame;

extracting the card image from the video frame;

generating metadata based on the extracted card image;

selecting a metadata subset based on one or more user preferences; and

outputting the video frame and the selected metadata subset to a display.

16. The non-transitory storage medium of claim 15 , wherein the video stream corresponds to a broadcast of a sporting event.

17. The non-transitory storage medium of claim 16 , wherein the video frame corresponds to a highlight of the broadcast.

18. The non-transitory storage medium of claim 17 , wherein the metadata corresponds to a status of the sporting event during the highlight.

19. The non-transitory storage medium of claim 17 , the operations further comprising:

outputting the metadata subset during viewing of the highlight.

20. The non-transitory storage medium of claim 15 , wherein the selecting the video frame region comprises cropping the video frame to isolate the video frame region.
