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).

摘要： A stream generation apparatus generates a stream including coded pictures and a command for managing a buffer which holds a decoded picture, the command being added to one of the coded pictures as a reference picture. A judging unit judges whether or not the coded picture to which the command is added is skipped at the time of trick-play, and an adding unit adds, in the case where the coded picture is judged to be skipped, repetition information indicating the same contents as the command to another coded picture that follows, in decoding order, the coded picture judged to be skipped and that is not skipped at the time of the trick-play. A generating unit generates the stream including the coded pictures, the command and the repetition information.
