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: A volume control apparatus comprises signal processing section for performing digital signal processing and a scaling process on an audio signal outputted from a sound source; level adjusting section for amplifying or attenuating a level of the audio signal outputted from the signal processing section, by an amount of adjustment determined based on an instructed amount of change, and outputting the amplified or attenuated audio signal to an outside; storage section for storing a level value of the audio signal outputted to the outside and the amount of adjustment for the audio signal adjusted by the level adjusting section; detecting section for detecting, when a volume controller is controlled by a user, time required for an amount of operation to reach a predetermined value; first setting section for setting an amount of operational change based on the level value stored in the storage section and the detected time; second setting section for setting an allowable amount of change by which the level adjustin
