Abstract
A video display apparatus with separate display means is provided so that the textual information can be displayed without preventing viewers from watching the full picture. The separate display means can be provided for a television receiver so that textual information, which includes closed caption text and subtitles, can be displayed on the separate display means without occupying the picture area. The separate display means can be provided for a screen in a movie theater so that subtitles can be displayed on the separate display means when a foreign movie is played. The separate display unit can be used to display other textual information, including a channel number, a name of the broadcasting station, the title of the current program and the remaining time of the current program. Furthermore, the separate display unit can display information on a local weather and a local time.
