Patent ID: 8855464

Claim:
A video reproduction apparatus comprising: a processor configured to perform signal processing on a video signal including a plurality of videos, the processor comprises a first processor configured to perform signal processing for display of the plurality of videos on the video signal and a second processor configured to convert the video signal including the plurality of videos into a video signal including a single video and to perform signal processing for display of the single video on the converted video signal; and a controller configured to determine that a battery usable time of glasses for viewing the plurality of videos is shorter than a reproduction time of a content corresponding to the video signal, and to stop output of a video signal on which the signal processing has been performed by the processor and to display a warning message for replacement or charging of a battery of the glasses when determines that the battery usage time of the glasses is shorter than the reproduction time of the content corresponding to the video signal, wherein the controller further is configured to (i) restart output of the video signal on which the signal processing has been performed by the processor when determining that the battery has been replaced or charged after the display of the warning message and (ii) either stop output of the video signal on which the signal processing has been performed by the first processor, or output of the video signal on which the signal processing has been performed by the second processor instead of the video signal on which the signal processing has been performed by the first processor when a detection signal indicating that remaining battery energy of glasses for viewing the plurality of videos is low is received, and to perform the output of the video signal on which the signal processing has been performed by the first processor when a detection signal indicating that the remaining battery energy of the glasses is not low is received.
