## Abstract

Provided is a recording medium that enables seamless connection between preceding playitems which are stream data arranged prior to a position where a long jump occurs, such as a layer boundary, and succeeding playitems which are stream data arranged subsequent to the position where the long jump occurs. A block exclusively for 2D playback Ln2D is arranged succeeding a 3D extent block in which a depth map data block, a right-view data block, and a left-view data block are arranged in an interleaved manner. A 3D extent block including a block exclusively for 3D playback L3SS is arranged between the block exclusively for 2D playback and a long jump point LB. The block exclusively for 2D playback and the block exclusively for 3D playback are identical in content.

## Claims

### Claim 1

A semiconductor integrated circuit for performing audio and video signal processing on data received from a recording medium, comprising:
a main-view stream used for monoscopic video playback, a plurality of main-view data blocks formed from the main-view stream;
a sub-view stream used for stereoscopic video playback in combination with the main-view stream, a plurality of sub-view data blocks formed from the sub-view stream;
2D management information used in monoscopic video playback; and
3D management information used in stereoscopic video playback,
wherein a common data area includes one or more of the plurality of main-view data blocks and one or more of the plurality of sub-view data blocks,
wherein a 2D data area includes one or more of the plurality of main-view data blocks,
wherein a 3D data area includes one or more of the plurality of main-view data blocks and one or more of the plurality of sub-view data blocks,
wherein the 2D management information refers to the one or more of the plurality of main-view data blocks included in the common data area and the one or more of the plurality of main-view data blocks included in the 2D data area,
wherein the 3D management information refers to the one or more of the plurality of main-view data blocks included in the common data area and the one or more of the plurality of main-view data blocks included in the 3D data area,
wherein the 2D management information does not refer to the one or more of the plurality of main-view data blocks in the 3D data area,
wherein the 3D management information does not refer to the one or more of the plurality of main-view data blocks included in the 2D data area,
wherein the 2D data area is accessed immediately before a long jump that occurs in monoscopic video playback,
wherein the 3D data area is accessed immediately before a long jump that occurs in stereoscopic video playback,
wherein the recording medium has the common data area, the 2D data area, and the 3D data area arranged continuously in this order, and
wherein the one or more of the plurality of main-view data blocks included in the 2D data area and the one or more of the plurality of main-view data blocks included in the 3D data area are identical in content,
the main-view data blocks and the sub-view data blocks both include visual data,
at least one of the main-view data blocks and the sub-view data blocks includes audio data, and
the semiconductor integrated circuit comprises:
a main control unit operable to control the semiconductor integrated circuit;
a stream processing unit operable to receive the interleaved stream and, after temporarily storing the received interleaved stream in one of memory units internal and external to the semiconductor integrated circuit, demultiplex the received interleaved stream into the visual data and the audio data;
a signal processing unit operable to decode the audio data and the visual data; and
an AV output unit operable to output the decoded audio data and the decoded video data, wherein
the stream processing unit includes a switching unit that switches a storage location of the received interleaved stream in the memory that has a first area and a second area,
in stereoscopic video playback, the main control unit causes the switching unit to store data contained in the main-view data blocks in the first area and to store data contained in the sub-view data blocks in the second area, and
the main control unit uses the 3D management information when causing the switching unit to store the data contained in the main-view data blocks in the first area.
