Abstract

A second screen system comprises a first screen that renders a first content comprising watermarks of a first type and watermarks of a second type. The watermarks of the first type are captured by a second screen that reacts to these watermarks. The second screen displays information to a user and receives user input. The second screen also watermarks a second content with watermarks of the second type and renders the second content. A third device captures watermarks of the second type in both the first content and the second content. Since the watermarks embedded by the second screen can depend on the user'"'"'s actions, the third device can indirectly react to the user'"'"'s actions.

Claims

1. A device comprising:

a memory;

at least one processor coupled to the memory, the at least one processor being configured;

to capture a first content rendered by a rendering device;

to extract payloads of first audio watermarks of a first audio watermark technology from the first content, and not to extract payloads of second audio watermarks of a second audio watermark technology from the first content;

to insert second audio watermarks of the second audio watermark technology with a payload into a second content to obtain audio watermarked second content; and

to render the audio watermarked second content.

2. The device of claim 1, wherein the at least one processor is further configured to:

display, via a user interface, information in response to received payloads;

receive input via the user interface in response to the information displayed; and

embed a watermark payload based on the input into the second content.

3. The device of claim 2, wherein the user interface is a touch screen.

4. The device of claim 2, wherein the at least one processor is configured to:

execute an application that is specific to the first content; and

cause the user interface to display the information in response to received payloads.

5. A system comprising:

a capture and embedding device comprising first processor circuitry;

a receiver device comprising a second processor circuitry, wherein the first processing circuitry is configured;

to capture a rendered first content with first audio watermarks of a first audio watermark technology and second audio watermarks of a second audio watermark technology;

to extract payloads of first audio watermarks of the first audio watermark technology from the first content and not to extract payloads of second audio watermarks of the second audio watermark technology;

to insert a second audio watermark of the second audio watermark technology with a payload into a second content to obtain audio watermarked second content; and

to render the audio watermarked second content, and the second processing circuitry is configured to;

capture the first content and the second content;

to extract payloads of second audio watermarks, of the second audio watermark technology, but not payloads of first audio watermarks of the first audio watermark technology; and

to react to the extracted payloads.

6. The system of claim 5, further comprising a rendering device with third processing circuitry configured to render the first content.

7. A method comprising:

capturing, by at least one processor, a first content rendered by a rendering device;

extracting, by the at least one processor, payloads of first audio watermarks of a first audio watermark technology from the first content, and not to extract payloads of second audio watermarks of a second audio watermark technology from the first content;

inserting, by the at least one processor, second audio watermarks of the second audio watermark technology with a payload into a second content to obtain audio watermarked second content; and

rendering, by the at least one processor, the audio watermarked second content.

8. The method of claim 7, further comprising

causing, by the at least one processor, a user interface to display information;

receiving, by the at least one processor, input via the user interface;

causing, by the at least one processor, the user interface to display information in response to received payloads; and

embedding, by the at least one processor, a watermark payload into the second content.

9. The method of claim 8, wherein the user interface is a touch screen.

10. The method of claim 8, further comprising selecting, by the at least one processor, the watermark payload to insert into the second content in response to the user input.

11. The method of claim 8, further comprising

executing, by the at least one processor, an application that is specific to the first content;

and

causing, by the at least one processor, the user interface to display the information in response to received payloads.
