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.

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.
