Apparatus and method for an additional contents display of an optical disc player

Abstract

This invention relates to a character display apparatus and method for a DVD (Digital Versatile Disc) player. According to the present invention, it is provided that font data of at least some of multi-languages to be used in multilingual subtitle processing are recorded on certain area(s) of a DVD, the recorded font data are stored in a font memory at initial stage of playback, the stored font data corresponding to a language selected by selection input of a user are then read, characters for subtitle processing of the selected language are displayed. Therefore, the manufacturing cost of DVD players can be reduced due to the reduction of memory capacity requied and DVDs can be maximum efficiently utilized.A character display apparatus for an optical disc player, and which includes a detection and separation unit to detect recorded data including a first font data from an optical disc, and to separate the first font data from the detected recorded data, a memory to store the first font data output from the detection and separation unit, a character generation unit to generate character signals for characters of a selected language for a subtitle by using the first font data stored in the memory, and a controller coupled to the character generation unit, to cause the character generation unit to generate the character signals for the characters of the selected language for character subtitle processing selected from multiple languages to be used in the character subtitle processing on the basis of the first font data. Further, the first font data is downloaded from the optical disc and stored in the memory such that the stored first font data is separate from the characters of the selected language before the character generation unit generates the characters of the selected language.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to character display for a digital versatile disc (DVD) player and particularly to a character display apparatus and method for a DVD player using font data recorded on a disc.[0003]2. Description of the Prior Art[0004]FIG. 1 is a block diagram of a conventional character display system for a DVD player. As shown in FIG. 1, conventional character display system is provided with a pickup 102 for detecting data recorded on a disc 101, a high frequency processing section 103 for processing the detected data of the pickup 102 and outputting video signals, a font ROM 104 for storing font data corresponding to multi-languages, a character generation section 105 for receiving the font data stored in the font ROM 104 and generating character signals of characters for subtitle processing a language selected by a user, and a controller 106 for controlling the high frequency processing section 103, th...
