The method includes simultaneously displaying first supplementary data (e.g., sub-picture data) and second supplementary data (e.g., caption data). The first supplementary data and the second supplementary data are supplementary to at least one of audio data and/or video data. In embodiments, the language of the first supplementary data may is different from the language of the second supplementary data. These embodiments are advantageous, as the connection between the first supplementary data and the second supplementary data may serve as a translation and assist in an understanding of context of the video data and/or the audio data. Accordingly, a viewer, whose native language, is not the language of the video data or audio data may be able to use the combination of the first supplementary and second supplementary data to learn the language of the video data or audio data.
An apparatus comprising:
A method comprising simultaneously displaying first supplementary data and second supplementary data, wherein the first supplementary data and the second supplementary data are supplementary to at least one of audio data and video data.
A method comprising displaying an accumulation of supplementary data associated with at least one of video data and audio data.
A method for displaying multi-text in an optical disc device comprising:

1. Field of the Invention
The present invention generally relates to playback devices.
2. Background of the Related Art
FIG. 1 is an exemplary block diagram illustrating a configuration of an optical disc device.
FIG. 2 is an exemplary diagram illustrating a structure of a sub-picture unit recorded in a DVD.
FIG. 3 is an exemplary diagram illustrating a relation between a corresponding sub-picture unit and sub-picture pack in a DVD.
An optical disc device (e.g., a DVD player) may be configured to read out video and/or audio data recorded as main titles on a high-density optical disc. In other words, in a DVD, read-out data is reproduced as digital images and/or audio signals. Further, a DVD may display a high quality picture and a high quality tone through an output appliance (e.g., a general TV).
In embodiments, DVDs may be recorded with caption information of diverse languages as sub-picture data. Sub-picture data may be randomly recorded as subtitles in a certain sector of a DVD so that they are reproduced and outputted in association with video and/or audio data corresponding to main titles. Caption data may be for hearing impaired persons. Caption data may also be used for other purposes (e.g., learning languages). Caption data may be recorded on a DVD to be associated with a video data stream of a main title. Accordingly, when video and/or audio data is read out during reproduction in a DVD player, sub-picture data and/or caption data may be simultaneously read out during reproduction. A user of a DVD player may view video data of a main title while identifying sub-picture data (e.g., caption information of diverse languages). A DVD player may read out and reproduce caption information from a DVD through a sub screen of the TV. Accordingly, it may be possible to efficiently enhance foreign language learning ability using an optical disk device.
A user may desire to search for and reproduce again a previously reproduced caption information during a language learning procedure carried out while viewing the caption information of diverse languages reproduced from an optical disc (e.g., a DVD). A user may desire to repeatedly reproduce a desired block of caption information. Accordingly, it may be necessary for a user to directly search for a position where sub-picture data of caption information is recorded through several key inputting manipulations. Accordingly, there may be inconveniences in use and a degradation in learning efficiency.
