摘要： A moving image encoding device includes a processor; and a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute, obtaining a region motion vector that represents a motion of a region including a block in a first slice, in a case where an encoding object block is included in a block line in a second slice, the block line contacting with a boundary between the first slice and the second slice in an encoding object picture, the encoding object picture being divided into a plurality of slices each of which includes a plurality of blocks; obtaining a motion vector of the encoding object block by using the region motion vector as a first prediction vector of the encoding object block; obtaining a second prediction vector from a motion vector of one or more encoded blocks; and obtaining an encoding result.

摘要： A video/audio synchronization apparatus includes: a decoder configured to decode a frame contained in encoded video data and determine playback time of the frame based on a first clock signal, and decode encoded audio data and determine playback time of an associated audio signal contained in the decoded audio data and to be played back simultaneously with the frame, based on a second clock signal different from the first clock signal; a silent period detector configured to detect a silent period from within the associated audio signal; and an audio timing adjuster configured to reduce a difference between the playback time of the frame and the playback time of the associated audio signal by skipping or repeating a silent period contained within a period of the associated audio signal.

摘要： An encoding device includes a processor configured to execute a process. The process includes: first calculating, based on a first system rate for encoding data and transmitting the encoded data to a terminal and a second system rate representing a rate for reproducing the data at the terminal, a decoder storage time during which the encoded data received by the terminal is stored; and adding information of the decoder storage time to the encoded data and transmitting the encoded data added with the information to the terminal.
