    摘要: The present invention provides an information recording medium in which an access unit including basic data and extension data is recorded, so as to allow a decoder that decodes only basic data to process the access unit which includes the basic data and the extension data for the next generation.The information recording medium is an information recording medium on which a stream, having plural access units and which includes at least one of image and audio, is recorded, wherein: each of the access units has: a first packet which includes basic data; and a second packet which includes extension data related to the basic data; the basic data is data that can be decoded in a completed state without requiring the extension data and the extension data is data for improving the quality of data generated from the basic data; and the stream includes information which indicates attributes of the first packet and the second packet.

    摘要: To provide means for accessing a content data stream efficiently even when the data stream is stored on multiple files. A data processor according to the present invention can write a content data stream on a medium. The data stream includes a plurality of pictures and a playback unit with one or more decoding units that need to be decoded from a base picture. The data processor includes: at least one of an encoder for generating the data stream and a receiving section for receiving the data stream; and a media control section for writing the data stream on the medium. If the size of a file, on which the data stream is being written, has exceeded a predetermined value, the media control section goes on to write the data stream on another file, generates a piece of information showing that the stored data of the playback unit has been split into these files, and writes the information on the medium.

    摘要: A BD-ROM has a video stream and an entry map recorded thereon. The entry map indicates a plurality of entry points (SPN_EP_start) in the video stream, in one-to-one correspondence with a plurality of entry times (PTS_EP_start) and flags (is_angle_change_point). Each flag (is_angle_change_point) indicates whether a picture located at a corresponding entry point is an IDR picture for causing decoder refresh or Non-IDR I picture having a reference to a preceding picture.

    摘要: The Procedure executing unit 42 makes a judgment on which among three conditions are satisfied by each of a plurality of audio streams. The BD-ROM reproduction apparatus selects an audio stream to be reproduced in accordance with each combination of conditions that are satisfied by each audio stream. One of the conditions is that a channel attribute of an audio stream is surround and the reproduction apparatus is capable to output surround audio. If the audio stream to be reproduced conforms to an encoding method such as DTS-HD or DD/DD+ whose audio frames are composed of basic data and extended data, the judgment on whether the surround output is available is made by judging whether or not the reproduction apparatus has a capability to process the extended data.

    摘要: A stream playback device for playing back an audio stream including audio frames which are each made up of base data and extension data is provided. The stream playback device includes a decoder and an interface unit operable to receive the audio stream supplied from a stream supply device. The stream playback device notifies the stream supply device whether only the base data or both the base data and the extension data are usable in decoding of the audio stream by the decoder, through the interface unit.
