Abstract

A method and system for encoding a content signal having one or more content segments. The one or more content segments of the content signal are identifying or obtained. One or more encoded patterns are superimposed or inserted in a segment portion of at least one of the one or more content segments by use of an insertion method that renders the one or more encoded patterns substantially invisible within the content signal. A method for detecting an encoded message within an encoded content signal. A pattern format is identified in at least one of the content segments. One or more encoded patterns are extracted from the one or more pattern formatted identified content segments. The one or more encoded patterns are decoded. The encoded message decoded from the encoded content signal is utilized.

Claims

1. A method comprising:

generating a message on an encoder, the message including a trigger for enhancement of game play associated with a game and game play enhancement data associated with the game;

generating a bar code from the message on the encoder, the bar code including the trigger and the game play enhancement data;

encoding the bar code on the encoder in an active portion of a video signal, the video signal being associated with the game; and

providing the encoded video signal to a broadcast source, the broadcast source capable of distributing the encoded video signal to a viewer.

2. The method of claim 1, further comprising:

receiving an operator instruction on the encoder; and

selecting a plurality of frames for encoding on the encoder based on receiving the operator instruction,

wherein encoding the bar code on the encoder is based on selection of the plurality of frames.

3. The method of claim 2, further comprising:

selecting an area of the plurality of frames on the operator instruction;

wherein encoding the bar code on the encoder is based on selection of the plurality of frames and the area.

4. The method of claim 1, further comprising:

generating an additional message on the encoder, the additional message including an additional trigger for enhancement of the game play;

generating an additional bar code from the additional message on the encoder, the additional bar code including the trigger and the game play enhancement data; and

encoding the additional bar code on the encoder in the active portion of the video signal.

5. The method of claim 1, wherein the video signal is a digital video signal.

6. The method of claim 1, wherein the bar code is encoded imperceptibly in the frame a plurality of frames of the video signal.

7. The method of claim 1, wherein the bar code is a multidimensional bar code.

8. The method of claim 1, wherein that broadcast source is a DVD device.

9. The method of claim 1, wherein encoding the bar code comprises:

encoding the bar code on the encoder in an active portion of a plurality of adjacent frames of the video signal.

10. The method of claim 1, wherein encoding the bar code comprises:

encoding the bar code on the encoder in the active portion of the video signal in a substantially invisible way.

11. A method comprising:

optically receiving an encoded video signal on a mobile electronic device from an electronic display device, the encoded video signal including a bar code encoded in an active portion of a plurality of frames of the encoded video signal;

identifying a portion of the encoded video signal as being in a bar code pattern format on the mobile electronic device;

decoding the bar code on the mobile electronic device to recover a message, the message including a trigger for enhancement of game play associated with an electronic game and game play enhancement data; and

enhancing the game play of the electronic game on the mobile electronic device using the game play enhancement data based on the trigger.

12. The method of claim 11, further comprising:

determining whether the bar code is valid on the mobile electronic device,

wherein decoding the bar code is based on a determination that the bar code is valid.

13. The method of claim 11, wherein the display device is a digital television.

14. The method of claim 11, further comprising:

notifying the user regarding the message based on decoding the bar code.

15. The method of claim 11, wherein a single frame of the video signal corresponds to the image.

16. The method of claim 11, wherein the video signal is a high definition (HD) video signal.

17. The method of claim 11, wherein the active portion is the visible portion of the encoded video signal when displayed on a display device, and the bar code is displayable in the visible portion.

18. The method of claim 11, wherein a portion of a frame of the video signal in which the bar code is encoded is in a bar code pattern format, further comprising:

enhancing the bar code pattern format by use of a pixel value threshold,

wherein decoding of the bar code to recover the message is based on enhancement of the bar code pattern format.

19. A non-transitory computer-readable storage medium comprising instructions, which when executed by a processor, cause the processor to:

optically receive an image of a video signal on a mobile electronic device from an electronic display device;

identify a bar code in an active portion of the video signal on the mobile electronic device;

decode the bar code on the mobile electronic device to recover a message, the message including a trigger for enhancement of game play associated with an electronic game and game play enhancement data; and

enhance the game play of the electronic game on the mobile electronic device using the game play enhancement data based on the trigger, the game play occurring synchronously with the video signal.
