An approach to decoding variable length code (VLC) symbols is described. In one embodiment, a method of decoding VLC symbols is detailed. This method involves obtaining a bitstream sample from a bitstream, and comparing the bitstream sample against a threshold value, to obtain a VLC group number. Information associated with a VLC group is retrieved, using this VLC group number. The current VLC symbol is extracted from the bitstream, using the VLC group information, and the corresponding symbol value is obtained, using the current VLC symbol and the VLC group information.
