Abstract

See full text

A device for decoding video data performs coefficient coding for a residual block of video data encoded using a transform skip mode by determining values for a first neighboring coefficient and a second neighboring coefficient and determining a context offset for the coefficient currently being decoded based on the value for the first neighboring coefficient and the value for the second neighboring coefficient. Performing coefficient coding includes, for example, performing sign coding, level mapping, and context derivation. The device performs coefficient coding to determine the residual block and adds the residual block to a predicted block to determine a reconstructed block.
