A video encoding method and apparatus are provided. The video encoding method includes determining whether a current block includes an affine-transformation object having an affine transformation; if the current block includes an affine-transformation object, generating a prediction block by performing affine transformation-based motion compensation on the current block in consideration of an affine transformation of the affine-transformation object; and if the current block does not include any affine-transformation object, generating a prediction block by performing motion vector-based motion compensation on the current block using a motion vector of the current block. Therefore, it is possible to achieve high video encoding/decoding efficiency even when a block to be encoded or decoded includes an affine transformation.

Methods of coding a bitstream in which the frames are encoded for enabling a spatial resolution is changed in real time, extracting the bitstream by adding a signaling message indicating that the spatial resolution is changed, and decoding the bitstream in which the spatial resolution is changed in real time after actively detects whether the spatial resolution is changed without additional information, and a codec using the methods are provided. Therefore, if the network has the restricted environment that the resolution is changed in real time while a video encoding and decoding or if there is a need to output the video whose the spatial resolution is partly changed in the decoder, the present invention provides methods to actively cope with the spatial resolution change of the video so as to efficiently watch the video.

Provided is an image encoding/decoding apparatus and method. The image encoding apparatus may include a motion vector prediction unit to perform a prediction with respect to an arbitrary motion vector of a current block within an image, using at least one of vector information of a motion vector corresponding to an adjacent block and vector information of a previous motion vector of the current block, and a differential determination unit to determine differential information of a motion vector of the current block based on the motion vector predicted in the motion vector prediction unit and an actual motion vector of the current block.

Provided are technologies that may perform intra coding of a super macro block that is an enlarged macro block. In this case, the super macro block is handled as a single entity or may be divided into a plurality of macro blocks. The present invention may perform intra coding both when the super macro block is handled as the single entity and when the super macro block is divided into the plurality of macro blocks.
