摘要:
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 pair of main-view and sub-view video streams, a graphics stream, and playlist information are recorded on a BD-ROM disc. The sub-view video stream includes metadata arranged in each GOP. The metadata includes a correspondence table associating offset identifiers and offset information. The offset information defines offset control for each picture in a GOP. Offset control is processing to provide a left offset and right offset for the horizontal coordinates in a graphics plane to generate a pair of graphics planes that are respectively combined with main-view and sub-view video planes. The playlist information includes a stream selection table for each playback section. When the stream selection table associates a stream number with a packet identifier of a graphics stream, one of the offset identifiers is further allocated to the stream number.

An image decoding device is provided which is capable of decoding views coded using inter-view prediction even when decoding is not instantly completed. The image decoding device includes: a decoding processing unit (100) which decodes a second view coded with reference to a first view; and a buffer memory (900) provided upstream of the decoding processing unit (100), and when the first view and the second view are assigned with an identical decoding point in time, the decoding processing unit (100) decodes a picture of the second view at a point in time determined by adding a delay time which has a length required to complete decoding of a picture of the first view, to the decoding point in time assigned to the picture of the second view.

An image coding method for properly handling a 3D video format including a base layer and an enhancement layer includes a video layer and a system layer. The video layer includes a step of coding an image to generate a coded stream. The system layer includes a step of multiplexing the coded stream and an identifier to generate a system stream, the identifier indicating whether or not the image has a left-right mixed format that includes a base layer and an enhancement layer and that has a left view image area and a right view image area in each picture. In the coding step, the image that includes the base layer and the enhancement layer and that has the left view image area and the right view image area in each picture is coded to generate the coded stream, when the image has the left-right mixed format.

Provided are video encoding device that encodes high-quality video, restricting increase of the required bandwidth, while maintaining playback compatibility with playback devices conforming to MPEG-2 standard, and video playback device. Data creation device 5401 includes: 2D compatible video encoder 2602 that generates stream conforming to MPEG-2 format by compress-encoding original video of normal quality; base-view video encoder 2605 that generates stream, composed of black images, that includes the same number of pictures as stream that is obtained by compress-encoding original video; and dependent-view video encoder 5409 that generates dependent-view video stream by compress-encoding higher-quality original video, by using, as reference pictures, pictures included in stream conforming to the MPEG-2 format that have the same time information as pictures included in the base-view video stream that correspond to pictures constituting higher-quality original video.
