    摘要: A system and method for characterizing the relative offset in time between audio and video signals and enables the receiver of the audio and video signals to resynchronize the audio and video signals. Signal characterization data is dynamically captured and encoded into frames of video and audio data that is output by a television origination facility. The signal characterization data is extracted by the receiver and signal characterization data is recomputed for the received frames. The extracted signal characterization data is compared with the recomputed signal characterization data to compute the relative offset in time between the video and one or more audio signals for a frame. The receiver may then resynchronize the video and audio signals using the computed relative offset.

    摘要: A system to prevent audio watermark detection includes content having a video portion and an audio portion, the audio portion having a watermark, an audio/video separator configured to separate the video portion and the audio portion, and a random number generator configured to generate a random number corresponding to a shifted frequency. The system also includes a frequency shift element configured to apply the shifted frequency to the audio portion to alter a spectrum of the watermark so as to prevent detection of the watermark by a device seeking to recover the watermark. The system also includes an audio resampler configured to resample the audio portion to restore the audio portion to an original length, and an audio/video combiner configured to combine the video portion and the audio portion.
