Abstract: A video system includes a video player for playing data of contents and an eyeglass device used to view a video. The eyeglass device includes an optical filter portion for adjusting a light amount reaching eyes of a viewer, a battery used as a power supply of the eyeglass device, and a first transceiver for transmitting remaining charge information on battery charge remaining in the battery and receiving a synchronization signal for controlling the optical filter portion. The video player includes a second transceiver for receiving the remaining battery charge information and transmitting the synchronization signal, and a controller for calculating a time period represented by operational time information of the eyeglass device based on the remaining battery charge information and causing the second transceiver to transmit the synchronization signal so as to make the optical filter portion less frequently operated.
