| 20140184905 | VOLUME LEVEL-BASED CLOSED-CAPTIONING CONTROL - Methods and apparatus are provided for a control of closed captioning based on an audio volume level. A content receiver detects that a volume of an audio of a video presentation has been adjusted by a user, and determines the adjusted audio volume level that results from the adjustment. The content receiver compares the resulting adjusted audio volume level to a threshold level. When the content determines that the adjusted audio volume level is under the threshold level, it enables closed captioning of the video presentation, thus presenting the user with both audio and closed captioning. When the content receiver determines that the adjusted audio volume level is above the threshold level, it disables closed captioning for the video presentation. The content receiver may use a microphone to determine the adjusted audio volume level. | 07-03-2014 |
