Abstract: The present invention provides an encoding apparatus including a setting section that partitions each of images included in a video to be encoded into a plurality of tiles and sets a partial region including one or more of the plurality of tiles for the image, an encoding section that encodes each image on a per-tile basis to generate an encoded stream, and a transmission control section that controls transmission of the encoded stream to a decoding apparatus that decodes the video. The setting section sets out-of-tile reference for motion compensation for the tiles within the partial region to be prohibited, and the transmission control section restricts, upon detection of a loss or an absence of encoded information at the decoding apparatus, the transmission such that only an encoded stream corresponding to the tiles within the partial region is transmitted.

Abstract: A video processing apparatus includes a combining unit that combines encoded streams of a plurality of videos to generate an encoded stream of a multiple-video image composed of the videos, each encoded stream of each video having coding units in each horizontal line that are encoded as a slice, and an insertion unit that inserts an insertion stream into the encoded stream of the multiple-video image generated by the combining unit when a view area of the multiple-video image is moved. The insertion stream is an encoded stream in which all the coding units in the multiple-video image are replaced with skip macroblocks with a motion vector indicating a direction and an amount of movement of the view area.

Abstract: The present invention makes it possible to easily implement a mechanism to recover an appropriately decoded video in a situation where encoded information for decoding the video has been lost or is absent. The present invention provides an encoding apparatus including: a setting section configured to partition each of images included in a video to be encoded into a plurality of tiles and set a partial region including one or more of the plurality of tiles for the image; an encoding section configured to encode each image on a per-tile basis to generate an encoded stream; and a transmission control section configured to control transmission of the encoded stream to a decoding apparatus that decodes the video. The setting section is configured to set out-of-tile reference for motion compensation for the tiles within the partial region to be prohibited, and the transmission control section is configured to restrict, upon detection of a loss or an absence of encoded information at the decoding apparatus, the transmission such that only an encoded stream corresponding to the tiles within the partial region is transmitted.
