KR960035606A - CD-eye with caption function and its disc format method - Google Patents

Abstract

The present invention relates to a system (Video-CD.CD-I) using a compact disc (CD) capable of outputting moving images. The present invention proposes a disk format method for performing a caption function using a 'user mode' provided in the CD-G. That is, the function of using font tables of major countries is defined by using R to W channels filled with '0' in general CD media. Therefore, the present invention not only can perform a caption function on a CD medium capable of outputting a moving image, but also brings the effect of providing a subtitle in a user's desired language.
