Abstract
A method for performing parallel coding with ordered entropy slices includes: providing a plurality of entropy slices to a plurality of processing elements with a causal criterion on processing order, wherein each entropy slice includes a plurality of macroblocks; and respectively starting to perform a coding procedure for the plurality of entropy slices according to the causal criterion, so that at least a portion of the processing elements are processed in parallel during at least a portion of processing time. An associated apparatus for performing parallel coding with ordered entropy slices includes: a plurality of processing elements; and a controller. The processing elements are arranged to process the entropy slices. In addition, the controller is arranged to provide the plurality of entropy slices with the causal criterion, and controls the operations of the processing elements.
