Abstract
Abstract An optical disc includes a data area for recording a plurality of video segments and an index area for recording original type chain information and user-defined type chain information. The original type chain information defines an original type chain including first ones of the video segments by describing a reproduction order of the first video segments. The user-defined type chain information defines a user-defined type chain including second ones of the video segments by describing a reproduction order of the second video segments. The first video segments are positioned in the data area in the reproduction order of the first video segments whereas the second video segments are positioned in the data area independently of the reproduction order of the second video segments.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
A reproduction apparatus for an optical disc on which section information and a video object including a plurality of video object units are recorded, wherein each video object unit includes a plurality of pieces of picture data, the section information contains reproduction start time information that specifies a piece of picture data contained in one of the plurality of video object units as a start point of a reproduction section, the reproduction apparatus comprising: a reading unit operable to read, from the optical disc, the video object unit containing the start-point piece of picture data; a decoding unit operable to decode the read video object unit to obtain a plurality of images to be reproduced; and a prohibition unit operable to, if one or more pieces of picture data exist before the start-point piece of picture data in the decoded video object unit containing the start-point piece of picture data, prohibit one or more images that correspond to the one or more pieces of picture data from being output for reproduction.
Claim 2
Dependent Claim
171 words
A reproduction apparatus for an optical disc on which section information and a video object including a plurality of video object units are recorded, wherein each video object unit includes a plurality of pieces of picture data, the section information contains reproduction start time information that specifies a piece of picture data contained in one of the plurality of video object units as a start point of a reproduction section, the reproduction apparatus comprising: a reading unit operable to read, from the optical disc, the video object unit containing the start-point piece of picture data; a decoding unit operable to decode the read video object unit to obtain a plurality of images to be reproduced; and a prohibition unit operable to, if one or more pieces of picture data exist before the start-point piece of picture data in the decoded video object unit containing the start-point piece of picture data, prohibit one or more images that correspond to the one or more pieces of picture data from being output for reproduction.
Claim 3
Dependent Claim
128 words
The reproduction apparatus of claim 1 , wherein the section information contains reproduction end time information that specifies another piece of picture data contained in another one of the plurality of video object units as an end point of the reproduction section, the reading unit reads, from the optical disc, the other video object unit containing the end-point piece of picture data, the decoding unit decodes the read video object unit to obtain a plurality of images to be reproduced, and if one or more pieces of picture data exist after the end-point piece of picture data, the prohibition unit prohibits one or more images that correspond to the one or more pieces of picture data after the end-point piece of picture data from being output for reproduction.
Claim 4
Dependent Claim
168 words
A reproduction method for an optical disc on which section information and a video object including a plurality of video object units are recorded, wherein each video object unit includes a plurality of pieces of picture data, the section information contains reproduction start time information that specifies a piece of picture data contained in one of the plurality of video object units as a start point of a reproduction section, the reproduction method comprising: a reading step for reading, from the optical disc, the video object unit containing the start-point piece of picture data; a decoding step for decoding the read video object unit to obtain a plurality of images to be reproduced; and a prohibition step for, if one or more pieces of picture data exist before the start-point piece of picture data in the decoded video object unit containing the start-point piece of picture data, prohibiting one or more images that correspond to the one or more pieces of picture data from being output for reproduction.
Claim 5
Dependent Claim
168 words
A reproduction method for an optical disc on which section information and a video object including a plurality of video object units are recorded, wherein each video object unit includes a plurality of pieces of picture data, the section information contains reproduction start time information that specifies a piece of picture data contained in one of the plurality of video object units as a start point of a reproduction section, the reproduction method comprising: a reading step for reading, from the optical disc, the video object unit containing the start-point piece of picture data; a decoding step for decoding the read video object unit to obtain a plurality of images to be reproduced; and a prohibition step for, if one or more pieces of picture data exist before the start-point piece of picture data in the decoded video object unit containing the start-point piece of picture data, prohibiting one or more images that correspond to the one or more pieces of picture data from being output for reproduction.
Claim 6
Dependent Claim
127 words
The reproduction method of claim 3 wherein the section information contains reproduction end time information that specifies another piece of picture data contained in another one of the plurality of video object units as an end point of the reproduction section, the reading step reads, from the optical disc, the other video object unit containing the end-point piece of picture data, the decoding step decodes the read video object unit to obtain a plurality of images to be reproduced, and if one or more pieces of picture data exist after the end-point piece of picture data, the prohibition step prohibits one or more images that correspond to the one or more pieces of picture data after the end-point piece of picture data from being output for reproduction.
