METHODS FOR ENCODING/DECODING HIGH DEFINITION IMAGE AND APPARATUSES FOR PERFORMING THE SAME

摘要

PURPOSE: An encoding/decoding method of high resolution image and apparatus performing the same are provided to increase the encoding/decoding efficiency by increasing the size of an expansion macro block. CONSTITUTION: An encoding apparatus receives a target frame(110). The encoding apparatus analyzes the frequency characteristic of the received frame(120). The encoding apparatus compares the frequency characteristic with the fixed critical value. The size of a macro block is decided with the mark encoded based on a comparison result(130).
