[0001]

BACKGROUND OF THE INVENTION The present invention relates to an AV system capable of multi-connecting a plurality of AV devices to a TV by switching and outputting an input signal from a selected AV (video / audio) device to a TV (television). More particularly, the present invention relates to an AV selector that enables a plurality of AV devices that output RF (radio frequency) signals and a plurality of AV devices that output AV signals to a TV device to be multi-connected.

[0002]

2. Description of the Related Art In recent years, AV devices such as video decks and video game machines have been developed, and various types of AV devices are often used by being connected to one TV. For this reason, conventionally, a plurality of AV devices can be connected to one TV by switching and outputting an input signal from the AV device selected by the selection switch to the TV side, so that the plurality of AV devices can be enjoyed. A known AV selector is known.

[0003] Meanwhile, the AV equipment outputs only an AV signal directly composed of an image signal and an audio signal as an output signal format, or outputs only an RF signal obtained by modulating a predetermined carrier with an AV signal, or an AV device. Signal and RF
Some output both signals. On the other hand, a TV is not only an RF signal input terminal for inputting a reception signal from an antenna, but also has an AV signal input terminal juxtaposed to enable connection with the above-mentioned AV equipment, and a TV such as a monitor TV. Some have only an AV signal input terminal.

Accordingly, there are two types of transmission / reception signals that enable the connection between the TV and the AV equipment, namely, the AV signal and the RF signal. ing.

When a plurality of DC-driven AV devices are connected to the AV selector, the power lines of the AC adapter become congested and complicated, and power lines with different driving voltages are erroneously wired to prevent damage to the AV devices. May be invited.

[0007] The present invention has been made in view of the above-described problems, and switches DC power only to a selected AV device and when an input signal from the AV device is different from a type of a signal to be output. An object of the present invention is to provide a selector which converts the input signal into a signal of a predetermined type, switches and outputs the signal, and enables a plurality of AV devices which output signals of different types to be multi-connected to a TV.
