摘要： A real-time customized promotion channel may be provided according to at least one attribute of digital contents displayed on a user device. Such a user device may include a communication circuit configured to receive channel service information from the server, an Input/Output (I/O) circuit configured to reproduce digital contents and output the reproduced digital contents to a display, and a controller configured to determine a promotion channel related to at least one attribute of the digital contents and request the determined promotion channel to the server. The communication circuit may be configured to receive the requested promotion channel from the server, and the I/O circuit is configured to reproduce the promotion channel and output the reproduced promotion channel through the display after the outputted digital contents ends.

摘要： Provided is s a method for a base station to allocate a time interval resource to transceive a downlink data channel (PDSCH) or an uplink data channel (PUSCH). The method include allocating a time interval resource for each OFDM symbol on the basis of a slot or a mini-slot, transmitting, to a terminal, time interval resource configuration information including OFDM symbol allocation data for OFDM symbols used for data channel transception in the slot or the mini-slot, and transmitting, to the terminal, control information selecting one of the symbol allocation data included in the time interval resource configuration information.

摘要： A method for decoding a video according to the present invention may comprise: deriving a spatial merge candidate for a current block, generating a merge candidate list for the current block based on the spatial merge candidate, obtaining motion information for the current block based on the merge candidate list, and performing motion compensation for the current block using the motion information. Herein, if the current block does not have a pre-defined shape or does not have a size equal to or greater than a pre-defined size, the spatial merge candidate of the current block is derived based on a block having the pre-defined shape or having a size equal to or greater than the pre-defined size, the block comprising the current block.
