  • Publication number: 20200213602
    Abstract: In a transcoding apparatus structured to transcode one bitstream to a plurality of bitstreams, a decoder decodes a first bitstream and outputs a first decoded picture. A first re-encoder re-encodes the first decoded picture on the basis of the first bitstream to generate a second bitstream having a smaller bit rate than the first bitstream.

  • Publication number: 20200137410
    Abstract: A prediction information deriving unit derives the inter-prediction information candidates from inter-prediction information of a prediction block neighboring to a coding target prediction block or a prediction block present at the same position as or near the coding target prediction block in a coded picture at a temporally different position from the coding target prediction block. A candidate supplementing unit supplements inter-prediction information candidates having the same prediction mode, reference index, and motion vector until the number of inter-prediction information candidates reaches the designated number of candidates when the number of inter-prediction information candidates is smaller than the designated number of candidates.

  • Publication number: 20190394486
    Abstract: A motion vector decoding unit derives a motion vector of a prediction block subject to decoding on the basis of a motion vector of a candidate block included in candidate blocks selected from neighboring blocks. The motion compensation prediction unit performs motion compensation prediction using the derived motion vector. In case a motion vector number of a first block and a motion vector number of a second block are identical with each other, the motion vector decoding unit determines whether or not to set the second block as a candidate block in accordance with whether or not a reference index indicating a reference picture that the motion vector of the first block refers to and a reference index indicating a reference picture that the motion vector of the second block refers to are identical with each other.

    Abstract: A prediction information derivation unit derives inter prediction information candidates from inter prediction information of coded prediction blocks neighboring a prediction block subject to coding within the same picture as the prediction block subject to coding and inter prediction information of a prediction block in a coded picture that is different from the prediction block subject to coding. The prediction information derivation unit determines an inter prediction information candidate to be used for inter prediction of the prediction block subject to coding from the inter prediction information candidates that have been derived. A second bitstream generation uni codes an index that indicates the inter prediction information candidate based on the number of the inter prediction information candidates.

    Abstract: A camera thumbnail image acquisition unit acquires a first thumbnail image from a camera. A distribution server thumbnail image acquisition unit acquires a second thumbnail image from a distribution server. A thumbnail image selection unit selects one of the first thumbnail image and the second thumbnail image as a thumbnail image that should be displayed. A camera information acquisition unit acquires camera information including streaming execution information indicating whether the camera is streaming. The thumbnail image selection unit refers to the streaming execution information to select the second thumbnail image as the thumbnail image that should be displayed when the camera is streaming and to select the first thumbnail image as the thumbnail image that should be displayed when the camera is not streaming.
