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.
Claims11
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.
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.
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.
