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

1-4. -4. (Canceled)

5. A decoding apparatus for decoding video object units which each include a plurality of pieces of picture data, the decoding apparatus comprising:

an interface operable to receive inputs of a first video object unit and reproduction section information that includes reproduction start time information indicating a start point of a reproduction section, the first video object unit including a piece of picture data corresponding to the start point;

a video decoder operable to decode a plurality of pieces of picture data included in the first video object unit to obtain a plurality of reproduction images; and

a prohibiting unit operable to, if the first video object unit includes one or more pieces of picture data before the piece of picture data corresponding to the start point, prohibit output of one or more reproduction images corresponding to the one or more pieces of picture data that precede the piece of picture data corresponding to the start point.

6. The decoding apparatus of claim 5, wherein

the reproduction section information includes reproduction end time information that indicates an end point of the reproduction section, and

the interface further receives an input of a second video object unit that includes a piece of picture data corresponding to the end point, wherein

the video decoder decodes a plurality of pieces of picture data included in the second video object unit to obtain a plurality of reproduction images, and

the prohibiting unit, if the second video object unit includes one or more pieces of picture data after the piece of picture data corresponding to the end point, prohibits output of one or more reproduction images corresponding to the one or more pieces of picture data that succeed the piece of picture data corresponding to the end point.

7. The decoding apparatus of claim 6, wherein

the interface further receives an input of pause information,

the decoding apparatus further comprises

an audio decoder operable to decode audio data included in the second video object unit to obtain reproduction audio, and

the audio decoder performs a pause process for the reproduction audio after the pause information is input.

8. The decoding apparatus of claim 7, wherein

the decoding apparatus decodes the second video object unit in accordance with a request from a control unit,

the control unit issues the pause information during a period of one audio frame that ends at the end point indicated by the reproduction end time information.
