Abstract: A method for supporting random access of MPEG data comprises the steps of: obtaining at least one access unit including media data, which is coded through a process including capsulation and packetization; generating at least one media processing unit (MPU) by grouping the at least one access unit; determining an initialization flag which indicates whether the at least one access unit in the at least one MPU includes all data required for initializing a decoding process; and inserting the initialization flag into at least one header of the MPU.

Abstract: PURPOSE: A receiving device for receiving multiple signals through different paths and a signal processing method thereof are provided to receive multiple signals transmitted through different networks and to synchronize the multiple signals. CONSTITUTION: A first receiving unit (210) receives a first signal through a radio frequency (RF) broadcast network. A second receiving unit (220) receives a second signal through an internet protocol (IP) communications network. A signal processing unit (230) detects synchronization type information from at least one signal of the first signal and the second signal. The signal processing unit selects synchronization information corresponding to the synchronization type information in the synchronization information included in the first signal and the second signal. The signal processing unit synchronizes the first signal and the second signal according to selected synchronization information.

Abstract: PURPOSE: A de-blocking method for a prediction block and a device thereof are provided to increase the efficiency of an encoding or decoding process by determining a boundary filtering strength when a skip encoding mode is applied to a boundary block. CONSTITUTION: When one or more encoded blocks exist in a block p and a block q, a de-blocking device determines a boundary filtering strength as 0 (S800, S810). When one or more intra-encoded blocks exist in the block p and the block q, the device determines the matching state between the boundary of the block p and the block q and the boundary of macro block (S820, S830). The device determines the boundary filtering strength according to the determination result (S840, S890).
