ABSTRACT:
Disclosed is a video playback apparatus which functions to vary the brightness of the caption color of a displayed caption according to audio level of the playback. The video playback apparatus displays caption signals on a predetermined area of a TV screen, and includes a level detector for detecting audio levels and a controller for controlling color brightness of the caption signals in response to and accordance with the audio levels detected. Thus, the captioned video signal (e.g. music lyrics) is displayed more vividly than heretofore.
