Abstract: An encoder includes a memory and a processor coupled to the memory and configured to: divide an image to be processed among sequentially input images into a plurality of small images; encode the plurality of small images; transmit each of the small images encoded by the encoding processing unit in correspondence with information indicating a position in the image to be processed; and change a division position of the image by the image dividing unit with respect to other image followed by the image to be processed according to processing information at the time of executing the encoding.

Abstract: At the time of an encoding process, a video elementary stream is generated and output by capturing and encoding a video image signal at a time interval of a video frame synchronous with a timing of a video synchronization signal, and an audio elementary stream is generated by capturing and encoding an audio signal at each audio interval. An audio packetized elementary stream where one packet has a stream length corresponding to the time interval of the video frame is multiplexed with the audio elementary stream, and the stream is output.

Abstract: A reception apparatus is configured to receive data including a plurality of packets each of which has information on a time point when the packet is generated; to extract a terminal packet which is a packet included in the data received and which has information on a time point which is nearest to a current time point; and to control an operation clock by comparing the information on the time point included in the terminal packet with information on an elapsed time obtained by adding information on a time point, which is included in a terminal packet of preceding data, to an elapsed time from when the preceding data is received to the current time point.

Abstract: A decoding device includes a first receiving section for receiving a data packets, a second receiving section for receiving a plurality of error correction packets which includes matrix configuration information regarding the plural data packets, a deciding section for deciding a number of packets to be accumulated to restore a lost data packet, based on the matrix configuration information, an accumulating section for accumulating the data packets received by the first receiving section in the number of packets to be accumulated, and a restoring section for, when a loss of any of the data packets received by the first receiving section is detected, restoring the lost data packet by using at least one of the data packets and the error correction packets.

Abstract: In the encoding/decoding system, when encoding an image, the image encoding device divides the encoding-target image into several subimages, and executes the encoding on the subimages in a direction moving away from the boundary of the divided subimages. In addition, when executing the encoding process, the image encoding device transmits pixels in the vicinity of the boundary of the subimages as uncompressed data, without encoding the pixels. Furthermore, when executing an encoding process, the image encoding device changes quantizing steps that are used in the encoding in accordance with a distance from the boundary so that an amount of data greater than or equal to a predetermined value can be assigned for the vicinity of the boundary by use of smaller quantizing steps.
