A low-complexity method for prevention of H.264 start code emulation by bit-handling routines with additional functionality. The low-complexity is achieved by employing a start code pre-determination scheme, which saves bitstream handling complexity by about 50% and 30% on the encoder and decoder sides, respectively. The start code emulation prevention has been embedded into the low-level bitstream handling routines. By doing so it avoids the use of the second bitstream buffer, maintains the decoder ability of using a circular bitstream buffer, and satisfies the BURST-aligned SDRAM access requirement.
