Abstract

A non-transitory computer readable recording medium and method and apparatus for reproducing and recording text subtitle streams including a style segment and presentation segments. The style segments define a region style, and each presentation segment contains a region subtitle associated with a region subtitle and presentation time information defining a presentation time of a corresponding presentation segment. The recording medium and method allow text subtitle streams to be more efficiently and effectively reproduced and recorded.

Claims21

Dependent claims

A non-transitory computer readable recording medium storing a data structure, the data structure comprising:

at least one text subtitle stream, each text subtitle stream including a style segment defining at least one region style and a plurality of presentation segments to which the style segment applies, each presentation segment containing at least one region subtitle and presentation time information, each region subtitle being linked to one of the at least one region style and including region information associated with the corresponding region subtitle, the presentation time information defining a presentation time of the corresponding presentation segment, the presentation time information including first information for indicating a presentation start time of the corresponding presentation segment and second information for indicating a presentation end time of the corresponding presentation segment,
wherein the region information includes data type information and data, the data being defined as inline style information or text string information according to the data type information, the data type information including an end-of-inline-style field for representing that each of the inline style information is applied until an end of the inline style information is detected.

A method of reproducing text subtitle streams, the method comprising:

reading, by a data reproducing apparatus, at least one text subtitle stream from a recording medium, each text subtitle stream including a style segment defining region styles and a plurality of presentation segments to which the style segment applies, each presentation segment containing at least one region subtitle and presentation time information, each region subtitle being linked to one of the region styles and including region information associated with the corresponding region subtitle, the presentation time information defining a presentation time of the corresponding presentation segment, the presentation time information including first information for indicating a presentation start time of the corresponding presentation segment and second information for indicating a presentation end time of the corresponding presentation segment,
wherein the region information includes data type information and data, the data being defined as inline style information or text string information according to the data type information, the data type information including an end-of-inline-style field for representing that each of the inline style information is applied until an end of the inline style information is detected;
and
decoding, by the data reproducing apparatus, the at least one text subtitle stream based on the style segment and the region information.

1 more element

An apparatus for reproducing text subtitle streams, the apparatus comprising:

a pickup configured to read data from a recording medium, wherein the data include at least one text subtitle stream, each text subtitle stream including a style segment defining at least one region style and a plurality of presentation segments to which the style segment applies, each presentation segment containing at least one region subtitle and presentation time information, each region subtitle being linked to one of the at least one region style and including region information associated with the corresponding region subtitle, the presentation time information defining a presentation time of the corresponding presentation segment, the presentation time information including first information for indicating a presentation start time of the corresponding presentation segment and second information for indicating a presentation end time of the corresponding presentation segment, wherein the region information includes data type information and data, the data being defined as inline style information or text string information according to the data type information, the data type information including an end-of-inline-style field for representing that each of the inline style information is applied until an end of the inline style information is detected;
a decoder configured to decode the at least one text subtitle stream from the pickup;
and
a controller operably connected with the pickup and the decoder, and configured to control the decoder to decode the at least one text subtitle stream based on the style segment and the region information.

1 more element

An apparatus for reproducing text subtitle streams, the apparatus comprising:

a decoder configured to decode at least one text subtitle stream, each text subtitle stream including a style segment defining at least one region style and a plurality of presentation segments to which the style segment applies, each presentation segment containing at least one region subtitle and presentation time information, each region subtitle being linked to one of the region styles and including region information associated with the corresponding region subtitle, the presentation time information defining a presentation time of the corresponding presentation segment, the presentation time information including first information for indicating a presentation start time of the corresponding presentation segment and second information for indicating a presentation end time of the corresponding presentation segment, wherein the region information includes data type information and data, the data being defined as inline style information or text string information according to the data type information, the data type information including an end-of-inline-style field for representing that each of the inline style information is applied until an end of the inline style information is detected;
and
a controller operably connected with the decoder and configured to control the decoder to decode the at least one text subtitle stream based on the style segment and the region information.
