摘要:
A moving image encoding method of encoding a moving image while switching between variable-length encoding schemes. In this method, a continuous unit to be continuously reproduced is determined (S5201), a stream is generated by encoding the moving image without switching between variable-length encoding schemes in the continuous unit (S5202), and management information is generated that includes a first flag information indicating that a variable-length encoding scheme is fixed in the continuous unit (S5204, and S5205).

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).

The encoding method obtains a video stream including pictures and display information, the pictures being L-R containing images each having a display area split into two sub-areas, one storing a left-view image and the other storing a right-view image. The display information includes 2D display information and 3D display information, each of which including cropping information specifying an area in the display area as an area to be cropped, the area in the display area specified by the cropping information of the 3D display information is for 3D display, and the area in the display area specified by the cropping information of the 2D display information is for 2D display, and is one of the left-view image and the right-view image.

A stream generation apparatus of the present invention is a stream generation apparatus which 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. It includes a judging unit which judges whether or not the coded picture to which the command is added is skipped at the time of trick-play, an adding unit which 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, and a generating unit which generates the stream including the coded pictures, the command and the repetition information.
