And a tuner unit 23 for tuning a desired broadcast signal through connection with an antenna, and an input selector 24 for selecting and outputting a tuning signal and an external input signal. The input selector 24 has a monitor output terminal connected to a recording VCR (not shown) for recording of the selected signal, and digital processing to receive at least two screen combinations by receiving the selected signal. The digital processing unit 25 converting and outputting the analog form is connected to each other. The apparatus of FIG. 2 also includes a transmitter 21 for manipulating A / V devices, a microcomputer 22 for receiving an operation signal transmitted through the transmitter 21 and controlling the operation of each component corresponding thereto; And a command output unit 28 for transmitting a command input through the microcomputer 22 to the corresponding A / V device. Between the microcomputer 22 and the digital processor 25, a signal reproducing unit 26 which receives menu signals and analog signals and outputs them in the form of color signals is connected. The signal reproducing section 26 is connected to an encoder section 27 for encoding a color signal and converting the color signal into an RF signal, and a TV output terminal connected to a television (not shown) for displaying the RF signal. On the other hand, the device of Figure 2 is a switch unit 29 for receiving and switching the AC power supplied from the outside under the control of the microcomputer 22, and the AC power delivered through the switch unit 29 of all the A / V devices It is provided with a plurality of AC power outputs (outputs 1 to 6) to supply the operating power.

An operation of the A / V device integrated control apparatus of the present invention configured as described above will be described in detail with reference to FIGS. 3 and 4.

FIG. 3 is a diagram showing a connection relationship between the FIG. 2 apparatus and the A / V apparatus, and FIG. 4 is a waveform diagram for explaining the power control of the FIG.

In FIG. 3, the set of FIG. 2 devices is located and interconnected between a television (TV) and other A / V devices such as VCRs, LDPs, CD-OKs, and the like. That is, the set is connected to the antenna of the RF input (RF IN), the antenna input of the television is connected to the RF output (RF OUT). The set is also connected one-to-one with video and audio output terminals of other A / V equipment except for television for six inputs, and the monitor output is connected with video and audio input terminals of the VCR. On the other hand, three of the six inputs in the set have terminals to enable S-VHS input. In addition, the AC power output is connected to the power of each A / V device so that the operating power of the connected A / V devices can be linked with the set power.

First, an antenna is connected to a set RF input (RF IN), and an RF output (RF OUT), which is a TV output terminal, is connected to an antenna input of a television (TV). Then, A / V devices (for example, VCR, LDP, CD-OK, CATV CONVERTER, DBS DECODER, etc.) are arbitrarily connected to input 1 to input 6. The user sets the connection state between the A / V device and the set in the microcomputer 22 through the transmitter 21. The tuner unit 23 selects a broadcast signal corresponding to a channel selected by the user through the transmitter 21 among the broadcast signals received through the antenna connected to the RF input RF IN, and outputs the broadcast signal to the input selector 24. The user selects one of the broadcast signals received through the antenna, and the signals input from each A / V device connected to the inputs 1 through 6. The microcomputer 22 receiving the signal transmitted from the transmitter 21 outputs a selection signal for the input selected by the user to the input selection unit 24. The input selector 24 selects the broadcast signal selected by the tuner 23 to the input 1 through the input 6 according to the selection signal applied from the microcomputer 22 and outputs it to the digital processor 25. When the signal selected by the input selector 24 is to be recorded, the selected signal is supplied to the recording VCR connected to the monitor output terminal when recording the selected signal to the recording VCR connected to the monitor output terminal. The digital processing unit 25 converts the input signal into a digital form, performs digital processing for at least two-screen reproduction, and then converts it into an analog form and outputs it to the signal reproducing unit 26. That is, when the user selects the input of the broadcast signal and the VCR connected to the input 4, the digital processor 25 receives the broadcast signal selected by the input selector 24 and the playback signal of the VCR, and performs double screen processing. . The signal reproducing unit 26 synthesizes the menu signal applied from the microcomputer 22 and the analog signal applied from the digital processing unit 25, and converts them into red (R), green (G), and blue (B) color signals. To the encoder unit 27. The encoder unit 27 converts the input color signal into a composite video signal of RF and supplies it to a television connected to the TV output terminal for display. In addition, the user selects detailed commands of the A / V devices (for example, in case of VCR, power on / off, play, fast forward, rewind, etc.) through the transmitter 21. do. The microcomputer 22 inputs a code corresponding to a command selected by the user through the transmitter 21 to the command output unit 28 with respect to the A / V device selected as an input. The command output unit 28 transmits the input code as a strong IR waveform signal IR. The A / V device receives the infrared signal IR and executes a corresponding command.

On the other hand, since the device may malfunction if the power of the devices are not initialized in this set, the external AC power is input from the set and supplied to the operating power of the connected A / V devices. That is, when AC power is applied from the outside, the switch unit 29 is turned on / off according to the power control signal CTL applied from the microcomputer 22 to supply power to the power output terminal. And block. As shown in FIG. 4, the switch unit 29 is turned off while the power supply control signal CTL applied from the microcomputer 22 is the first section T1 of the low level. At this time, the set is in a stand-by mode, and power supply to the A / V device is cut off. On the other hand, the power supply control signal CTL is turned on during the second section T2 of the high level, and the set is turned on and supplies power to the A / V device. . Therefore, since the power of interconnected A / V devices is supplied in conjunction with the set power supply, malfunction of the A / V devices can be prevented.

As described above, the A / V device integrated control apparatus of the present invention maintains the existing television as it is, and is interconnected between the television and a plurality of A / V devices, thereby enabling integrated control with one transmitter. It has the effect of simplifying the use and management of V equipment.
