摘要： A data creation device performing compression encoding on first frame images showing a view from a first viewpoint and second frame images showing a view from a second viewpoint generates a stream in an MPEG-2 format, and base-view/dependent-view video streams in a format conforming to an MPEG-4 MVC format. The stream in the MPEG-2 format is generated by performing compression encoding on the first frame images. The base-view video stream is a stream of dummy data having the same number of frames as and a smaller data amount than the stream in the MPEG-2 format. The dependent-view video stream is obtained by performing compression encoding on each frame of the second frame images, with reference to a frame of the stream in the MPEG-2 format to be presented at the same time as a frame of the base-view video stream corresponding to the frame of the second frame images.

摘要： To provide a moving picture stream generation apparatus and the like that generates a moving picture stream that can be played back in trick-play such as variable-speed playback and reverse playback even in a coding format such as the MPEG-4 AVC in which flexible prediction structures are allowed.A moving picture stream generation apparatus includes: a trick-play information generation unit TricPlay for generating supplemental information on a random access unit basis, the supplemental information being referred to at the time of playback of each random access unit and each random access unit including one or more pictures; and a variable length coding unit VLC for generating a stream including the generated supplemental information and the one or more pictures by adding the supplemental information to each corresponding random access unit. At the top of each random access unit, an intra coded picture that can be decoded without depending on any picture is placed, and the supplemental information includes information for specifying pictures to be decoded at the time when pictures included in each random access unit are played back in trick-play.

摘要： An image decoding method includes a first storage step of sequentially decoding pictures in a stream, storing a picture to be used as a reference into a picture memory, and managing the picture. Further, the image decoding method includes a determination step of determining whether or not random access reproduction has been designated, a state change step of changing a management state for managing a picture in the picture memory, when the random access reproduction has been designated, and a second storage step of sequentially decoding each of the coded pictures from a random access reproduction destination, storing, into the picture memory, a picture to be used as a reference, and managing the picture. This image decoding method enables the decoding of pictures with reference to an appropriate picture even when random access reproduction is performed.

摘要： A data reproduction device is provided for achieving seamless reproduction of a stream where a validity of a bandwidth extension function is switched in the stream. The data reproduction device includes an input frequency obtainment unit analyzing header information Hdr and obtaining an input frequency FSin, which is the frequency of basic data, an output frequency determination unit performing predetermined processing based on the input frequency FSin and determining an output frequency FSout, which is the sampling frequency of a decoded frame Fdata, and a decoding unit (2003) which, if the SBR function is valid in a frame to be decoded, decodes sample data at the input frequency FSin and extends the bandwidth of the sampling frequency up to the output frequency FSout, while if the SBR function is not valid in the frame, upsamples the decoding result obtained at the input frequency FSin to the output frequency FSout.
