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.

Image encoding/decoding apparatus and method

Provided is an apparatus and a method for providing a three-dimensional (3D) broadcasting service that may provide a two-dimensional (2D) fixed broadcasting service using a fixed broadcasting signal or a 2D mobile broadcasting service using a mobile broadcasting signal when a transmitter transmits each of a left image and a right image constituting a 3D image using the fixed broadcasting signal or the mobile broadcasting signal, and the receiver receives the fixed broadcasting signal and the mobile broadcasting signal, or may provide a 3D broadcasting service by composing an image received using the fixed broadcasting signal and an image received using the mobile broadcasting signal into a 3D image.

Apparatus and method for 3D broadcasting service in broadcasting system combined with mobile broadcasting

Provided is a video encoding apparatus, including a signal separator to separate a differential image block into a first domain and a second domain, based on a boundary line included in the differential image block, the differential image block indicating a difference between an original image and a prediction image with respect to the original image, a transform encoder to perform a transform encoding with respect to the first domain using a discrete cosine transform (DCT), a quantization unit to quantize an output of the transform encoding unit in a frequency domain, a space domain quantization unit to quantize the second domain in a space domain, and an entropy encoder to perform an entropy encoding using outputs of the quantization unit and the space domain quantization unit.

Motion picture encoding apparatus and method thereof

A data processing system and method for stereoscopic 3D video based on MPEG-4. Various elementary streams of left and right images of stereoscopic 3D video are multiplexed into a single stream, and efficient buffer management is performed through field encoding that supports possible display methods. The system minimizes the synchronization time of left and right images and reduces the complexity of the decoder model. Also, a decoding buffer size is allocated to enable support of stereoscopic 3D video field/frame shuttering and stereoscopic 3D video polarized display, while maintaining compatibility with conventional 2D video data processing. Finally, only DTS and CTS are transmitted at the same time, and DTS and CTS of the remaining times are estimated to thereby simplify synchronization.
