Abstract
In general, this disclosure described techniques for pruning a list of motion vector prediction candidates based on picture order count (POC) values. A video coding device may be configured to generate the list of motion vector prediction candidates for a prediction unit (PU) of video data. The video coding device may prune a first motion vector prediction candidate from the list of motion vector prediction candidates when a POC value for a reference picture identified by the first motion vector prediction candidate is equal to a second POC value of a reference picture identified by a second motion vector prediction candidate in the list of motion vector prediction candidates. The video coding device may code the PU using the pruned list.
