ABSTRACT:
A digital video coding system is provided that is capable of reducing the load of a CPU (Central Processing Unit) that controls a video coding system for implementing a digital video data compression/decompression standard such as MPEG-1, 2, 4, H.261 or H.263. In a conventional video coding system, the circuit configuration and control method of a variable length encoder are becoming increasingly complex with the development of a video compression/decompression standard. In a conventional system structure, a complex control operation must be carried out, such that there is a problem in that the load of the CPU controlling the video coding system increases. Thus, the video coding technology is provided to reduce the load of the CPU necessary for controlling a VLC (Variable Length Coding) unit.
