VARIABLE LENGTH CODING APPARATUS AND METHOD FOR FLEXIBLY DEALING WITH CHANGE AND ADDITION OF A VARIABLE LENGTH CODING TABLE AND FOR PROCESSING DATA AT HIGH SPEED

摘要

Variable length encoding method is disclosed with device. Variable length coding apparatus according to the present invention, by having a pre-programmed software modules of the variable-length encoding for predetermined manner, input symbolic data, by variable-length encoding, generates a variable length code information, central processing unit using software module; From central processing unit it is characterized in that it includes: an independent processor, bit stream processor are used to generate a reception input information bits and flow to variable length code. To, it is easy to the software modules that there is the VLC tables support of downloading can implement in the separation application specific processor by reducing the load on device for change or addition promote new video encoding standard and the execution of bit stream data processor may high-speed data processing in the central processing as caused by variable-length encoding.
