Abstract
A method and apparatus for recording time information for received digital data streams are provided. The method includes recording first time information and second time information on a recording medium. The first time information is part of management data for managing presentation data and the second time information is time information of the presentation data. The format of the first time information coincides with the format of the second time information.
Claims37
A method of recording time information associated with digital data, the method comprising:
- (a) generating first time information and second time information, the first time information being part of management data for managing presentation data and the second time information being time information included within the presentation data;
- and
- (b) recording the first and second time information on a recording medium,
- wherein a format of the first time information is the same as a format of the second time information, and the format of each time information includes a base part having a bigger unit value and an extension part having a smaller unit value.
An apparatus for recording time information associated with digital data, the apparatus comprising:
- a time information generating unit configured to generate first time information and second time information, the first time information being part of management data for managing presentation data and the second time information being time information included within the presentation data;
- a recording unit configured to record the digital data on a recording medium;
- and
- a controller configured to control a recording mode to record the first and second time information on the recording medium,
- wherein a format of the first time information is the same as a format of the second time information, and the format of each time information includes a base part having a bigger unit value and an extension part having a smaller unit value.
A method of reproducing digital data, the method comprising:
- (a) reading first time information and second time information recorded on a recording medium, wherein the first time information is part of management data for managing presentation data and the second time information is time information included within the presentation data, the presentation data comprising a data object unit including video data, and at least the second time information being set to a presentation start time of the video data in the data object unit, wherein a format of the first time information is the same as a format of the second time information, and the format of each time information includes a base part having a bigger unit value and an extension part having a smaller unit value;
- and
- (b) reproducing video data based on the first time information and the second time information.
An optical disc including time information associated with digital data, the optical disc comprising:
- a recording layer for storing digital data;
- and
- first time information and second time information recorded on the recording layer, wherein the first time information is part of management data for managing presentation data and the second time information is time information included within the presentation data, and wherein a format of the first time information is the same as a format of the second time information, and the format of each time information includes a base part having a bigger unit value and an extension part having a smaller unit value.
An apparatus for reproducing digital data, the apparatus comprising:
- a time information reading unit configured to read first time information and second time information recorded on a recording medium, wherein the first time information is part of management data for managing presentation data and the second time information is time information included within the presentation data, the presentation data comprising a data object unit including video data, and at least the second time information being set to a presentation start time of the video data in the data object unit, and wherein a format of the first time information is the same as a format of the second time information, and the format of each time information includes a base part having a bigger unit value and an extension part having a smaller unit value;
- and
- a reproducing unit configured to reproduce video data based on the first time information and the second time information.
