Abstract
A device includes a memory configured to store image data and an image coding unit implemented in circuitry. The image coding unit is configured to code a first value of a first instance of a first syntax element of a first block of image data and determine a first context for coding a second value of a second instance of the first syntax element of a second block of the image data. The image coding unit is configured to context-based code the second value of the second instance of the first syntax element of the second block of the image data after coding the first value of the first instance of the first syntax element using the first context and code a third value of a first instance of a second syntax element of the first block in parallel with coding the second value or after coding the second value.
