摘要： A method of synchronizing reference image with additional image in digital broadcasting includes generating at least one frame having predetermined identifier for providing notice of the start time of the reference image to receiver in advance; and transmitting at least one frame having the predetermined identifier to the receiver. Alternatively, the method of synchronizing reference image with additional image of includes generating signaling information containing additional image interlocking information at a transmission side in order to prepare for the additional image interlocked with the reference image at a reception side in advance; and providing the signaling information to the receiver. Therefore, it is possible to accurately and effectively perform the synchronization of 3D reference image with 3D additional image stored in the receiver or a streamed 3D additional image.

摘要： Disclosed are an image encoding method using a skip mode and a device using the method. The image encoding method may comprise the steps of: judging whether there is residual block data of a prediction target block on the basis of predetermined data indicating whether residual block data has been encoded; and, if there is residual block data, restoring the prediction target block on the basis of the residual block data and an intra-screen predictive value of the prediction target block. Consequently, encoding and decoding efficiency can be increased by carrying out the encoding and decoding of screen residual data only for prediction target blocks where there is a need for a residual data block in accordance with screen similarity.
