A video device includes a broadcast signal processor, a display component, a speaker, and a controller. The broadcast signal processor is configured to receive a digital broadcast signal and process the digital broadcast signal. The display component is configured to display video based on the digital broadcast signal outputted from the broadcast signal processor. The display component has a light source. The speaker is configured to output main audio of the video based on the digital broadcast signal outputted from the broadcast signal processor. The controller is configured to determine whether or not the digital broadcast signal includes sub audio for visually impaired. The controller is further configured to output the sub audio for the visually impaired with the main audio of the video from the speaker and turn off the light source of the display component when the controller determines that the digital broadcast signal includes the sub audio for the visually impaired. |
