Abstract
A system and method for embedding digital audio watermarks in audio source information based at least upon identified video content are described. An audio/video processing system receives audiovisual data. A video content analyzer within the system analyzes video source information of the audiovisual data, determines video content depicted by data in the video source information, and generates an indication of the video content. An audio watermark embedder of the system receives the indication, and based at least in part on the indication, adjusts watermark embedding parameters used for embedding the audio watermark in the audio source information.
Claims17
An audio watermarking embedder comprising:
- an interface configured to receive an identification of video content represented by data in a video frame;
- and control logic configured to:
- select a watermark embedding parameter used for embedding an audio watermark in an audio frame based at least in part on the identification of video content;
- embed the audio watermark in an audio frame corresponding to the video frame based at least in part on the selected watermark embedding parameter;
- embed a first amount of data of the audio watermark in the audio frame based at least in part on detecting the identification of video content represents a first scene;
- and embed a second amount of data different from the first amount of data of the audio watermark in the audio frame based at least in part on detecting the indication of video content represents a second scene different from the first scene.
A method comprising:
- receiving an indication identifying video content depicted by data in a video frame;
- selecting a watermark embedding parameter used for embedding an audio watermark in an audio frame based at least in part on the identification of video content;
- embedding the audio watermark in an audio frame corresponding to the video frame based at least in part on the selected watermark embedding parameter;
- embedding a first amount of data of the audio watermark in the audio frame based at least in part on detecting the identification of video content represents a first scene;
- and embedding a second amount of data different from the first amount of data of the audio watermark in the audio frame based at least in part on detecting the indication of video content represents a second scene different from the first scene.
An audio/video processing system comprising:
- a video content analyzer;
- and an audio watermarking embedder;
- wherein the video content analyzer is configured to:
- analyze data in a video frame;
- identify video content depicted by the data;
- and generate an indication of the video content;
- and wherein the audio watermarking embedder is configured to:
- receive the indication of the video content;
- select a watermark embedding parameter used for embedding an audio watermark in an audio frame based at least in part on the identification of video content;
- and embed the audio watermark in an audio frame corresponding to the video frame based at least in part on the selected watermark embedding parameter;
- embed a first amount of data of the audio watermark in the audio frame based at least in part on detecting the identification of video content represents a first scene;
- and embed a second amount of data different from the first amount of data of the audio watermark in the audio frame based at least in part on detecting the indication of video content represents a second scene different from the first scene.
