Abstract

A device for video decoding may determine a range of values for a coordinate associated with a non-zero coefficient of a transform block (TB). The coordinate may indicate a sample location associated with the non-zero coefficient in the TB. The device may determine a context-adaptive binary arithmetic coding (CABAC) context for entropy decoding a coordinate indication indicating whether a coordinate suffix associated with the range of values may be received. The device may determine the coordinate based on the coordinate indication. The device may decode the TB based on the coordinate associated with the non-zero coefficient. The device may entropy decode the coordinate indication associated with the coordinate based on the CABAC context. The device may determine that the coordinate suffix is not to be received and/or that the coordinate is to be determined based on a subset of the range values and/or the size of the TB.
