A method for coding image information includes generating prediction information by predicting information on a current coding unit, and determining whether the information on the current coding unit is the same as the prediction information. When the information on the current coding unit is the same as the prediction information, a flag indicating that the information on the current coding unit is the same as the prediction information is coded and transmitted. When the information on the current coding unit is not the same as the prediction information, a flag indicating that the information on the current coding unit is not the same as the prediction information and the information on the current coding unit are coded and transmitted. At the generating of the prediction information, the prediction information is generated by using the information on the coding unit neighboring to the current coding unit.

Method for encoding video information and method for decoding video information, and apparatus using same

According to one embodiment of the present invention, a video information encoding method comprises: a step of predicting information of the current coding unit to generate prediction information; and a step of determining whether the information of the current coding unit coincides with the prediction information. If the information of the current coding unit coincides with the prediction information, a flag indicating that the information of the current coding unit coincides with the prediction information is encoded and transmitted. If the information of the current coding unit does not coincide with the prediction information, a flag indicating that the information of the current coding unit does not coincide with the prediction information is encoded and transmitted and the information of the current coding unit is encoded and transmitted. In the step of generating prediction information, the prediction information may be generated using the information on the coding unit adjacent to the current coding unit.

Disclosed herein is a method for coding image information, including: generating prediction information by predicting information on a current coding unit; and determining whether the information on the current coding unit is the same as the prediction information, wherein when the information on the current coding unit is the same as the prediction information, a flag indicating that the information on the current coding unit is the same as the prediction information is coded and transmitted, and when the information on the current coding unit is not the same as the prediction information, the flag indicating that the information on the current coding unit is not the same as the prediction information and the information on the current coding unit are coded and transmitted.
