Equipment for adding subtitles to video and audio programs in real time

Abstract

The invention discloses equipment for adding subtitles to video and audio programs in real time, and relates to the field of intelligent hardware. The device comprises an HDMI IN interface which is connected with a video and audio content providing device and is configured to receive video and audio programs output by the video and audio content providing device; a control unit which is connectedwith the HDMI IN interface, and is configured to convert the voice of the video and audio programs into texts in real time, generate subtitles again, and match and superpose the subtitles on the pictures of the video and audio programs; an HDMI OUT interface which is connected with the control unit and the display, and is configured to output a picture of the video and audio program with the caption superimposed to the display; and an HDMI BY PASS circuit which is connected with the two interfaces and is configured to directly connect the two interfaces to directly output video and audio programs when the equipment enters a standby state. One-screen output of subtitles and video and audio frames is achieved, and the pain that hearing impaired people cannot watch subtitle-free video and audio programs or can only watch in a multi-screen cooperation mode is thoroughly solved.
