Disclosed herein are systems and methods for performing SAG effect compensation on a video signal received over an AC-coupled video link. In one aspect, a method for performing SAF effect compensation includes applying a filter to the received video signal to generate a corrected video signal, where a transfer function of the filter is dependent on a transmission parameter that is based on a plurality of parameters of the AC-coupled link. The method further includes extracting predefined content from the corrected video signal, and adjusting the transmission parameter based on a comparison of the extracted predefined content with certain expected content, so that adjusted transmission parameter can be used for one or more subsequent applications of the filter, thereby realizing an adaptive filter.

Methods and devices for compensating sag effect

Disclosed herein are systems and methods for communicating video signals and control data over a HD, wired, AC-coupled video and control link. In one aspect, an example system includes a scheduler that is configured to allocate time slots for exchange of data between a transmitter and a receiver over such a link. The scheduler is configured to, for each of at least one or more video lines of a video frame of a video signal acquired by a camera, allocate a plurality of time slots for transmitting a plurality of video components of said video line from the transmitter to the receiver, allocate one or more time slots for transmitting transmitter control data from the transmitter to the receiver, and allocate one or more time slots for transmitting receiver control data from the receiver to the transmitter.

High definition analog video and control link for automotive applications

A flash ADC circuit may include a reference ladder providing reference signals and a plurality of comparators, each providing an output based on a comparison of a pair of input signals to a pair of reference signals. At least one pair of the comparators may receive the same pair of reference signals with a different orientation of the reference signals at each of the comparators. The flash ADC may include a switch network for swapping the pair of reference signals between the pair of comparators.

Flash ADC shuffling

A converter system, including a first converter that digitizes the a first portion of an input signal, the first converter including a comparator, a timer having a circuit structure that emulates a circuit structure of a comparator in the first converter, the timer receiving an input signal indicating commencement of operations in the comparator, a second converter that digitizes a second portion of the input signal remaining from the first portion in response to an output from the timer, and a combiner having inputs to generate a digital code from the digitized first and second portions.
