Fine grain methods for parallelization of the H.264 decoder have good latency performance and less memory usage. However, they could not reach the scalability of coarse grain approaches although assuming a well-designed entropy decoder which can feed the increasing number of parallel working cores. The authors would like to introduce a GOP (Group Of Pictures) level approach due to its high scalability, mentioning solution approaches for the well-known memory issues. Their design revokes the need to a scanner for GOP start-codes which was used in the earlier methods.
