ABSTRACT:
A method for covering and revealing a translated caption in a video reproducing apparatus, which includes a key input circuit for operating control keys selected by a user, a microcomputer coupled to the key input circuit for controlling the apparatus in response to a selected key input, an OSD processor for processing OSD characters, a caption processor for generating a caption, a video signal output circuit for generating a composite video signal including the OSD characters, the caption, and a video signal, and a display for displaying an image corresponding to the composite video signal, includes steps for selecting and storing a start and end position corresponding to the orientation in which the translated caption is displayed, e.g., horizontally or vertically, and generating shadow characters for display between the start and end positions so as to cover the translated caption. Thus, the user can cause the translated caption to be selectively revealed. A video reproducing apparatus suitable for performing the translated caption covering method is also described.
