Abstract: PURPOSE: A method for generating an encoding table for Korean character compression encoding and a method for Korean character compression encoding by using the same are provided to transmit a lot of Korean character data generated in case of data broadcasting by using a digital TV after compressing the Korean character data. CONSTITUTION: A method for generating an encoding table for Korean character compression encoding includes the steps of extracting samples of Korean character data being used for broadcasting(11), obtaining the generation probability of each symbol in the extracted Korean character data samples(12), generating an encoding table by executing Huffman encoding after confirming whether the generation probability of each symbol is more than a predetermined value(13-14), and constructing a compression encoding table related to all symbols having the generation probability over the regular value(15-16).

Abstract translation: 目的：提供一种用于生成用于韩文字符压缩编码的编码表的方法和使用该方法的韩文字符压缩编码方法，用于在压缩数字电视之后通过使用数字电视发送数据广播时产生的大量韩文字符数据 韩文字符数据。 构成：用于生成韩文字符压缩编码的编码表的方法，包括以下步骤：提取用于广播的韩文字符数据的样本（11），获取所提取的韩文字符数据样本（12）中的每个符号的生成概率， 在确认每个符号的生成概率是否大于预定值（13-14）之后，通过执行霍夫曼编码来生成编码表，并且构造与具有超过常规值的生成概率的所有符号相关的压缩编码表（15- 16）。
