Abstract: According to one embodiment, a transceiver acquires actual consumption data and predicted consumption data for each time slot, from a power supply management system. A data analysis block analyzes the actual consumption data and the predicted consumption data, and generates graph data representing a graph showing a result of the analysis. A display control block causes a display device to display the graph and a power-save line in the graph. A power-save line control block moves the power-save line to a desired position and utilizes a value associated with the desired position as a value at which to start power saving. A command signal output block outputs a power-save command signal to an apparatus which should save power, if the actual consumption data and/or the predicted consumption data exceed the value indicated by the power-save line.

Abstract: According to one embodiment, a video output apparatus includes an input module, an output module, and a transmitter. The input module is configured to input a 2D content and a 3D content. The output module is configured to alternately output a first image and a second image required to display images having a parallax at image output timings based on the 3D content, and to repetitively output 2D content images at the image output timings based on the 2D content. The transmitter is configured to transmit, to 3D image glasses which open and close a right-eye shutter and a left-eye shutter, timing control signals, which indicate open/close timings of the right-eye shutter and the left-eye shutter in synchronism with the image output timings of the output module, for both the 2D content and the 3D content.
