An amplification apparatus comprises: an amplifier circuit that amplifies an input audio signal and outputs an output audio signal; a first signal level determining unit that determines whether or not a signal level of the output audio signal outputted from the amplifier circuit is lower than a silence determination reference value; and a power-supply control unit that shifts the amplification apparatus from a power-on state to a power-off state, when it is determined that the signal level of the output audio signal outputted from the amplifier circuit is lower than the silence determination reference value.

Amplification apparatus

An AV system in which a power feeding apparatus and a plurality of power receiving apparatuses are connected in a daisy chain with the power feeding apparatus in the lead, wherein the power feeding apparatus includes: a connection detecting line; an applying unit for applying a voltage to the connection detecting line; and a power supply unit for supplying a power to the power receiving apparatus or suspends the supply of the power according to a voltage level of the connection detecting line, the power receiving apparatuses include: a contents signal output unit for outputting a contents signal upon the supply of the power; a ground terminal having a ground potential; a conducting line connectable to the ground terminal in another power receiving apparatus adjacent on the rear; and a first switch unit for enabling the connection detecting line to be connected to any one of the ground terminal and the conducting line and holding a connected state even when the power is not supplied.

A battery charger includes: a resume information table for storing resume information about contents to be started to be reproduced with a portable player being connected to the battery charger; a writing unit that writes resume information about a tune being reproduced just before the portable player is disconnected from the battery charger into the resume information table; and an instructing unit that reads the resume information stored in the resume information table when the portable player is connected to the battery charger, and transmits an instruction for reproducing a specified tune to the portable player.

Reproducing control device having resuming function

A command conversion deviceis connected between an amplifier deviceand a portable player. The amplifier devicesends/receives a plurality of types of first commands corresponding to a plurality of types of devices (e.g., CD players, MD recorders, tape recorders, etc.), and performs an operation based on a received first command. The portable playersends/receives a second command, and performs an operation based on a received second command. The command conversion deviceincludes a selector for selecting a type of a first command, and a converter. When a first command of the type selected by the selector is received from the amplifier device, the converter converts the received first command into a second command, and sends the second command to the portable player

Command conversion device and charging device for content reproduction device

If a sub broadcast is unavailable so a reception means receives the main broadcast instead of the sub broadcast, reception of the sub broadcast is booked. When the sub broadcast is booked and the sub broadcast becomes available, the reception means automatically receives the sub broadcast booked instead of the main broadcast. Accordingly, reception of the sub broadcast can start automatically when the sub broadcast starts, without inputting instructions to select the sub broadcast repeatedly, whereby operation performed by a user can be simplified.
