Video parameter set for hevc and extensions

Abstract

A video processing device can be configured to process one or more initial syntax elements for a parameter set associated with a video bitstream; receive in the parameter set an offset syntax element for the parameter set that identifies syntax elements to be skipped within the parameter set; and based on the offset syntax element, skip the syntax elements within the parameter set and process one or more additional syntax elements in the parameter set that are after the skipped syntax elements in the parameter set.
