Abstract
An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to analyze an audio-video data stream to determine watermark appropriate information for the audio-video data stream. The second circuit may be configured to communicate the watermark appropriate information either in-band with or out-of-band from a bit stream communicating the audio-video data.
Claims27
An apparatus comprising:
- a first circuit configured to analyze an audio-video data stream to determine watermark appropriate information for said audio-video data stream;
- and
- a second circuit configured to communicate said watermark appropriate information either in-band with or out-of-band from a bit stream comprising said audio-video data.
A method for watermarking audio-video data comprising the steps of:
- performing one or more analyses selected from the group consisting of spatial analysis, temporal analysis and transform domain analysis, on said audio-video data;
- and
- communicating a result of said one or more analyses either in-band with or out-of-band from a bit stream comprising said audio-video data.
An apparatus for decoding a compressed bit stream comprising:
- a first circuit configured (i) to detect watermark appropriate information communicated in-band with or out-of-band from an audio-video data bit stream and (ii) to extract said watermark appropriate information;
- and
- a second circuit configured to embed one or more watermarks in said audio-video data based upon said watermark appropriate information.
A method for decoding a compressed bit stream comprising:
- detecting watermark appropriate information communicated either in-band with or out-of-band from an audio-video data bit stream;
- extracting said watermark appropriate information;
- and
- embedding one or more watermarks in said audio-video data based on said watermark appropriate information.
