Disclosed herein are systems and methods for performing DC offset correction of a video signal received over an AC-coupled video link. In one aspect, a transmitter is configured to compute, and provide to a receiver, metadata indicative of a statistical characteristic (e.g., an average or a sum of values) for a group of active pixels of a video signal acquired by a camera. The receiver is configured to compute an analogous statistical characteristic on the video signal received over an AC-coupled video link, and to perform DC offset correction by modifying one or more values of the received video signal based on a comparison of the statistical characteristic computed by the receiver and the one computed by the transmitter and indicated by the received metadata.

A device for coding video data includes a memory comprising a decoded picture buffer (DPB) configured to store video data, and a video coder configured to code data representative of a value for a picture order count (POC) resetting period identifier, wherein the data is included in a slice segment header for a slice associated with a coded picture of a layer of video data, and wherein the value of the POC resetting period identifier indicates a POC resetting period including the coded picture, and reset at least part of a POC value for the coded picture in the POC resetting period in the layer and POC values for one or more pictures in the layer that are currently stored in the DPB.
