摘要： Disclosed is a method for transmitting and receiving control information. The method for transmitting control information according to the present invention, in a mobile communication system in which a control channel region and a data channel region are separated from each other, comprises the steps of: determining a control channel resource for transmitting control information by means of the data channel region; and transmitting the control information using the determined control channel resource. According to the present invention, a capacity for control information, which increases for multiple user multiple-input multiple-out (MIMOs) in a heterogeneous network environment, for heterogeneous network interference control using carrier aggregation, for frequent use of a multicast-broadcast single frequency network (MBSFN) subframe, and for a CoMP transmission control, may be satisfied. Further, an adaptive resource allocation based on a requested capacity for control information may be enabled, and the efficient utilization of resources may also be enabled.

摘要： According to the present invention, an image encoding/decoding method comprises the steps of: performing an intra prediction on a current block so as to generate a prediction block; performing filtering on a filtering target pixel in the prediction block on the basis of the intra prediction mode of the current block so as to generate a final prediction block; and generating a reconstructed block on the basis of a reconstructed differential block corresponding to the current block and on the final prediction block. According to the present invention, image encoding/decoding efficiency can be improved.

摘要： Provided is a method for providing a DMB-based 3D stereoscopic image service using an MPEG-4 object descriptor of a new structure to provide users with a realistic 3D image service while maintaining compatibility to a conventional DMB system, and a decoding apparatus and method for the DMB-based 3D stereoscopic image service. The method includes the steps of: a) defining in a data service component type that a broadcast service is a DMB service, and defining a dimension of the DMB service in a user application type; and b) assigning a reference image and 3D additional information for a serviced 3D image as different streams which are independent from each other by using different object descriptors.
