Abstract: A method for 3DTV multiplexing according to the present invention comprises, deriving a delay value in units of frames for the left and right image based on a left image PES (Packetized Elementary Stream) corresponding to a left image and a right image PES corresponding to a right image, carrying out synchronization of the left image PES and the right image PES based on the delay value in units of frames, and generating 3DTV transport streams (TSs) by carrying out multiplexing of the synchronized left image PES and the synchronized right image PES. According to the present invention, efficiency of video services can be improved.

Abstract: 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.
