Generating apparatus flows moving image coding apparatus moving images, mux apparatus and moving image decoding apparatus moving images

An apparatus for generating a flow of moving images which generates a stream including pictures queconstituyen a moving picture, said apparatus generating a flow of enmovimiento images comprising: a first unit operable for encoding a first supplemental information included in a unit of random access, including the random access unit group of images whose primeraimagen is an image I (i) including the first additional information fragments plural information image types indicating types of all the pictures included in the group, and (ii) being used when the pictures included in the random access unit are played back in trick-play, and the plural pieces of information of image types placed in an order that corresponds to a decoding order of the group of pictures being, and plural pieces of image types include informationof at least: an I picture on which performs intra-coding; unaimagen P on which the inter-coding with reference to a picture per block which isa basic unit in coding is performed; a first image B on which performs inter-codificacioncon reference to two pictures per block which is a basic unit in coding, and which can be referenced in an image; and a second image B on which it performs intercodificacion with reference to two pictures per block which is a basic unit in coding, and andcannot be referenced from any other picture; a second unit operable for encoding a second supplemental information included in the random access unit, (i) including the second additional information plural pieces of information of image structures, indicating structures of all the pictures included in the group, and (ii) being used when the pictures included in the random access unit are played trick enreproduccion, plural pieces of information of image structures placed inthe order corresponding to the order of decoding the group of pictures being; and plural fragments Infomessages of image types include at least information indicating whether the picture structure of each picture is a field structure, a first frame structure for displaying the image using doscampos display, or a second frame structure for displaying the image, using three camposde display, by repeatedly displaying a first display field on a downlink time Deuso advance 3-2.
