Abstract: The method for controlling interface according to one embodiment of the present invention comprises the steps of: detecting the state of connection with one or more sink devices and one or more source devices which are connected to input and output ports of a multimedia interface module; identifying one or more operation modes available for the detected connection state; and transmitting device information of the one or more sink devices to the one or more source devices, the device information being selectively edited in accordance with a requested operation mode among the identified operation modes. Therefore, various operation modes such as Through, Convert, Switch, Mix, Distribute, Duplicate and Exchange can be chosen for effective operation, thereby enhancing the convenience of the user and increasing the performance of interface between the sink devices and source devices.

Abstract: The present invention provides video encoding and decoding methods using block merging, which can be applied to a high resolution video of more than HD (High Definition) resolution. A video encoding method includes partitioning a current block into a first and a second prediction unit by using asymmetric partitioning, constructing a list of common merging candidate blocks including a predetermined number of common merging candidate blocks selected from adjacent blocks of the current block, selecting at least one candidate block from among the list of common merging candidate blocks and sending information of the selected candidate block to a decoder for each of the first and the second prediction unit.
