Abstract: According to one embodiment, an electronic apparatus includes a communication module, a memory, and a controller. The communication module is configured to transmit a power status request command to one or more connection apparatuses and to receive responses to the command. The memory is configured to store power statuses of the one or more connection apparatuses based on the responses. The controller is configured to select an input of a connection apparatus in a power-on state based on the power statuses in response to a first input switching operation.

Abstract: According to an aspect of the invention, a video display apparatus includes: a sensor that measures an external environment to output the external environment; a storing unit that stores a correction value associated with the measured value; a adjusting unit that changes the correction value based on a given operation by a user; and a processor that adjusts a picture quality of a picture to be displayed on a display based on the measured value and the correction value.

Abstract: An image reproduction system includes a TV set, an AV amplifier connected to the TV set, and a plurality of image output devices, such as a DVD player, a set-top box and a game console, connected to the AV amplifier. The ID information of these image output devices is displayed as a list on the screen of the TV set. The user can select any one of the image output devices from the list by using a remote control, for example. The fact of the selection is transmitted to the AV amplifier from the TV set. Upon this, the AV amplifier connects the selected image output device to the TV set, so that the image signals reproduced by the selected device are sent to the TV set.

Abstract: According to one embodiment, a video display apparatus includes a generation module and a transmitting module. The generation module is configured to generate, when an operation mode change that changes the time required for video signal processing is requested, a device control signal in which information indicating the time required for video signal processing in the requested operation mode is written. The transmitting module is configured to transmit the device control signal generated by the generation module via a transmission line of the device control signal to cause an audio reproduction apparatus to set a delay amount of audio reproduction.
