Abstract: Disclosed is a decoding method which uses an intra-screen prediction. A decoding method which uses an intra prediction performed in a decoding apparatus comprises the steps of: receiving a bit stream; obtaining decoding information from the received bit stream; generating a prediction block for a current block to be decoded using the obtained decoding information; and restoring the current block by adding a residual block obtained from the bit stream and the prediction block. Accordingly, a compression ratio of an image can be improved.

Abstract: A unified radio application interface and a reconfigurable mobile device utilizing the same are disclosed. The unified radio application interface, which is one of interfaces mounted on the reconfigurable mobile device, comprises: a first module for a radio application management service; a second module for a user data flow service; and a third module for a multi-radio control service, wherein the unified radio application interface provides at least one of a radio application management service, a user data flow service, and a multi-radio control service to a radio control framework (RCF) operating on a radio computer of a mobile device and to an unified radio application (URA) operating on a radio computer, and supports the RCF so as to reconfigure a radio application according to a wireless communication environment or a wireless connection environment of the mobile device.
