System and method for just in time embedded watermarking of streaming proxies

A system and method for just-in-time embedded watermarking of streaming digital content. The system employs sequential processing to transcode streaming content to embed a user-specific watermark into the streaming content.

Accordingly, the just-in-time embedded watermarking system provides consistent and predictable user playback experience. Further, the system automatically supports adaptive bit rate optimization by providing interoperability with multiple potential adaptive bit rates requestable by the content player device. The system watermarks the requested content segment in real-time during the streaming of the content by causing burn-in of the user-specific watermark into the streaming content.

COMPRESSED DOMAIN ENCODING APPARATUS AND METHODS FOR USE WITH MEDIA SIGNALS

METHOD AND APPARATUS FOR COPY PROTECTION FOR VARIOUS RECORDING MEDIA USING A VIDEO FINGER PRINT

A method and apparatus for copyright protection for various recording media such as Digital Video Discs (DVDs) uses a combination of a Video Finger Print Signal and an Authenticating Signature to permit the player to handle either copy-protected or non-copy-protected media, in a manner that is difficult to compromise. Both a Video Finger Print Signal and an Authenticating Signature are recorded on the media only when copy-protection is required. The nature of this Authenticating Signature is such that it will not be transferred to illicit copies made on CD recorders. When either an original protected or an original non-protected disk is played, the presence or absence of the Authenticating Signature causes the player to correctly play the program video. All original DVDs therefore play normally. When a copy of a nonprotected CD is played, the absence of the Video Print Signal also causes the player to correcly playback the video signal data. However, when a copy of a protected CD is played ...

Correlation-based system for watermarking continuous digital media

A correlation-based system for watermarking continuous digital media at the system application level. It is a post-compression process for watermarking where no a priori knowledge of the underlying compression algorithm is required. Per each compressed media frame, a current unique digital signature is generated based on the data from the current compressed frame plus the digital signature that has been previously generated. The signature thus generated is then used in conjunction with the next compressed frame to generate the next unique digital signature. All digital signatures are correlated according to the above process until a “reset” signal is issued. A new chain of correlated digital signatures is produced by the system with a pre-determined initial signature.

PRE-DISTRIBUTION IDENTIFICATION OF BROADCAST TELEVISION CONTENT USING AUDIO FINGERPRINTS

Systems, devices and methods are provided to automatically identify advertisements or other portions of a broadcast television stream before the stream is distributed via a cable, DBS, IPTV or other medium. The television broadcast is received at the data processing system, and audio content of the television broadcast is analyzed to generate an audio fingerprint of a portion of the audio content. The identified audio fingerprint are compared to audio fingerprints stored in a database to thereby identify the portion of the television broadcast based on the generated audio fingerprint. By identifying the contents of an actual broadcast prior to redistribution of the broadcast, additional actions may be taken that are unique to the identified content.
