    Abstract: An encoder includes circuitry and memory connected to the circuitry. In operation, the circuitry: stores MV information and correction processing information into a FIFO buffer for an HMVP mode in association, the MV information being derived for a processed block and correction processing information being related to correction processing of a prediction image of the processed block; registers, in a prediction candidate list for a merge mode, one or more prediction candidates each being a combination of MV information and correction processing information, the prediction candidates including a prediction candidate which is a combination of the motion vector information and the correction processing information stored in the FIFO buffer; and selects a prediction candidate from the prediction candidate list when a current block is to be processed in the merge mode, and performs correction processing of a prediction image of the current block, based on the correction processing information.

    Abstract: Provided is a method for transmitting a broadcasting content and a line content, the broadcasting content and the line content being synchronously displayed, the method including: generating a line parity packet from a plurality of line data packets in each of which the line content is stored; transmitting the line data packet and the line parity packet through a communication line; and transmitting a plurality of broadcasting data packets in each of which the broadcasting content is stored, from a base station using a broadcasting wave, a transfer clock time of the broadcasting content being delayed by a predetermined time compared with a transfer clock time of the line content. At this point, video quality can be improved when the real-time broadcasting program content and the real-time line content are simultaneously displayed.
