Aspects of the present disclosure include a method, a switch, and/or a computer readable medium for analyzing a window of samples at an expected position of a plurality of input edges of a plurality of input waveforms, detecting the plurality of input edges, measuring a displacement of each input edge, with respect to a previous position, of the plurality of input edges, generating a value of the displacement of each input edge, incrementing a corresponding counter value of a plurality of accumulator values in response to each value of the displacement of a corresponding accumulator of the plurality of accumulators, normalizing the plurality of accumulator values, generating the plurality of accumulator values, summing the plurality of accumulator values output by the plurality of accumulators to generate an accumulated jitter value, and sending jitter result information based on the accumulated jitter value.

Apparatuses and methods for jitter measurement

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 that use video line inversion for reducing impact of periodic interference signals on analog transmission of video signals over wired links/connections. In one aspect of the present disclosure, in certain circumstances, a transmitter may be configured to perform video line inversion on a certain subset of video lines of a video signal prior to transmitting the video signal to the receiver, and a receiver may be configured to perform a corresponding inversion for the same subset of video lines of the video signal received at the receiver. Such video line inversion performed by the transmitter and the receiver may advantageously allow reducing or eliminating the impact of periodic interference signals that might affect the video signal during transmission, resulting in an improved quality of the video rendered at the receiver side.

Video line inversion for reducing impact of periodic interference signals on analog video transmission

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.
