ENCODER AND ENCODING METHOD IN VIDEO CODING STANDARD

摘要

The present invention relates to an encoding apparatus and method in the H.264 / AVC video compression standard. An encoding method according to an embodiment of the present invention creates a memory structure capable of effectively storing a VLCT used in Coeff_token encoding. That is, codewords existing in the VLCT are divided into length information and value information, and the length information and the value information of the codewords are stored in each allocated memory area. The size of the length information of the codeword is configured to be reduced, and the length information of the reduced codeword is stored in the allocated memory area. The encoding method according to the embodiment of the present invention can improve the performance of the encoding system and reduce the implementation cost of the encoding system by using a reduced size encoding table.
