A system for generating and detecting watermarks within a video frame (e.g., video content) is described to determine whether a data interruption has occurred. In one or more implementations, the system includes a generation module communicatively coupled to a video source and a watermark detection module configured to receive a plurality of video watermarks. The watermarking detection module is configured to determine whether a watermark embedded in a current (e.g., a second) video frame is different from a watermark embedded in the previous (e.g., a first) video frame. The watermarking detection module is configured to generate an error signal when the watermark embedded in the current (e.g., a second) video frame is not different than the watermark embedded in the previous (e.g., a first) video frame to indicate a data interruption event has occurred.

Apparatus and method for protecting real-time safety and security relevant video data

Various embodiments of the invention enable low-power accurate measurement of complex impedance at a range of frequencies of interest to determine a frequency response of a test sample. The system requires only a few external precision components that are not integrated into a microprocessor, thereby, providing a low-cost alternative to existing designs. In certain embodiments, low-power operation is accomplished by utilizing a simplified digital signal processing scheme that requires only a small number of ADC samples. Measurement accuracy is achieved by a digital conversion to baseband that does not suffer from channel matching issues and by utilizing a single analog path.

Systems and methods for low power time-domain measurement of complex impedance

Various embodiments of the innovation provide adaptive equalization training for a receiver in a communication system. In certain embodiments, the receiver's coefficients are re-optimized while links are active and initialized.

Non-disruptive adapter equalizer coefficient update method for active links

An example method for controlling a continuous time linear equalizer includes: developing a voltage histogram of a signal present at an output of a continuous time linear equalizer; developing a quality factor for the voltage histogram; comparing the quality factor with a prior quality factor; decreasing an equalization of the continuous time linear equalizer if the quality factor is less than the prior quality factor and increasing the equalization of the continuous time linear equalizer if the quality factor is greater than the prior quality factor.
