摘要： 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.

摘要： The present invention relates to a method and apparatus for encoding and decoding video information. The video information encoding method according to the present invention comprises: a step of performing a prediction on a current block; and a step of entropy-encoding the predicted information and transmitting the encoded information. The step of performing a prediction comprises: a step of acquiring motion information on a neighboring block from the neighboring block of the current block; and a step of determining motion information on the current block on the basis of the acquired motion information. The transmitting step also involves transmitting information required for the prediction of the current block.

摘要： The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.
