    摘要: Provided is a multiplexer which can reliably analyze side information which a decoder in the multiplexer can fundamentally identify. A multiplexer (10a) generates data by assigning different packet identifiers to (i) one of coded video data and coded audio data, and (ii) table data regarding the coded data, and packet-multiplexing the coded data and the table data. The multiplexer (10a) includes: a sub-descriptor generating unit (14) which generates sub-descriptors, each of which includes a sub-tag value representing a type of side information representing a parameter for decoding the coded data, and the side information; a descriptor generating unit (11) which generates a main descriptor including the sub-descriptors generated by the sub-descriptor generating unit (14), and a main tag value representing a set of the sub-descriptors; and a table generating unit (12) which generates the table data, by associating the main descriptor generated by the descriptor generating unit (11), with the packet identifier of the coded data. The sub-descriptor generating unit (11) outputs the sub-descriptors in an order defined by a predetermined storage rule.

    摘要: A moving image coding method that can prevent playback discontinuity without an increase in processing load during playback is provided.The moving image coding method codes a video stream that includes a first moving image and a second moving image to be overlaid on the first moving image. The moving image coding method includes: a step of determining a continuous playback section that is a group of partial sections and is subject to continuous playback, in the video stream (S5301 to S5303); a step of coding the first and second moving images in the partial sections constituting the continuous playback section, under a constraint that prevents a threshold from being changed in the continuous playback section, the threshold being used for a transparency process by a luminance key in the overlaying (S5304); and a step of generating management information including flag information which indicates that the threshold is fixed in the continuous playback section (S5305).
