Systems and methods for reference offset signaling in video coding

Abstract

A device for deriving prediction sample values for encoding data is provided. The device includes one or more processors, and one or more non-transitory computer-readable media coupled to the one or more processors and storing one or more computer-executable instructions. When the computer-executable instructions are executed by at least one of the one or more processors, the computer-executable instructions cause the device to encode a reference wraparound offset syntax specifying an offset used for computing a horizontal wrap-around position, to derive a luma location based on a product of a value of the reference wraparound offset syntax and a minimum coding block size, and to derive a predicted luma sample value by using the luma location. A maximum value of the reference wraparound offset syntax is determined based on a quotient obtained by dividing a width of each decoded picture by the minimum coding block size.

Dependencies are inferred from the claim text.
