[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home terminal for connecting to a device such as a television receiver for reproducing CATV and processing and outputting the received CATV signal.

[0002]

2. Description of the Related Art First, a conventional multi-remote control transmitter capable of remotely controlling such a home terminal will be described. FIG. 5 shows the appearance of the multi remote control transmitter 1. Reference numeral 2 is an operation key common to each controlled device, and 3 is a controlled device selection key. The operation keys 2 are used to operate power on / off, channel up / down, volume up / down, and the like. A controlled device selection key 3 is used to select a controlled device such as a home terminal and a television receiver. For example, when operating the home terminal, the home terminal is selected by the controlled device selection key 3 and the power of the home terminal is turned on / off and the channel u is pressed by the operation key 2.
Control p / down, etc. When operating the television receiver, the controlled device selection key 3 is used to select the television receiver, and the operation key 2 is used to turn the television receiver power on / off and the channel up / d in the same manner as described above.
Perform operations such as down, volume up / down, and the like.

However, when the television receiver is selected, the transmission data when the operation key 2 is pressed differs depending on the manufacturer of the television receiver, so that the manufacturer of the television receiver 10 connected in advance is manufactured. It is necessary to input the above data to the remote control transmitter 1 and set its control code. As an example of the input method, there is a method of simultaneously pressing the operation key 2 assigned to each manufacturer of the television receiver 10 while pressing the controlled device selection key 3.

Next, an internal circuit diagram of the multi-remote control transmitter 1 will be described with reference to FIG. The controlled device selection key 3 is provided with 3HT and 3TV. The controlled device selection key 3HT is a key for selecting a home terminal as a controlled device, and the controlled device selection key 3TV is a television. This is a key for selecting the receiver. Reference numeral 7 denotes a microcomputer, which controls each unit in the multi-remote control transmitter 1. Reference numeral 6 is a battery that contributes to the operating power supply of the multi-remote control transmitter 1.

Each key of the controlled device selection key 3 (3HT,
3TV) and each key of the common operation key 2 (2a, 2b,
2c, ...) At the bottom, when any of those keys are pressed, the input terminals B, C, D, E of the microcomputer 7
One of the output terminals F, G, H, and I is connected at the same time. The microcomputer 7 determines which one of the controlled device selection key 3 and the operation key 2 is pressed from the combination of the connected input and output. For example, when a current flows from the output terminal E and a current enters the input terminal G, the microcomputer 7 determines from this information that the controlled device selection key 3TV
It is determined that is pressed, that is, the television receiver is selected.

In addition, in the memory in the microcomputer 7, the remote control data of the home terminals and other controlled devices manufactured by each manufacturer are sorted by each manufacturer, each controlled device, and each control command. It is stored in advance. The microcomputer 7 retrieves the remote control data corresponding to the information pressed by the operation key 2 of the device selected by the controlled device selection key 3 after the manufacturer is set, from all the remote control data stored in advance. If there is corresponding remote control data, this is output from the output terminal A to the transistor 4. The output remote control data is amplified by the transistor 4, converted into the infrared carrier signal 8 by the infrared light emitting diode 5, and output.

Next, a block diagram of a general home terminal will be described with reference to FIG. Here, the multi-remote control transmitter 1 is the one shown in FIGS. 5 and 6 and described in detail above, so that both the home terminal 9 and the television receiver 10 can be operated by one unit.

A CATV input signal a is input through the terminal 11.
Is input to the distributor 12. The distributor 12 is a CATV
The input signal a of is divided into two branch signals a1 and a2, and the branch signal a1 is output to the tuner 13 and the branch signal a2 is output to the data receiver 18.

The tuner 13 selects a channel by the control signal d input as channel selection data from the control circuit unit 19, and selects the branch signal a1 input from the distributor 12 as an intermediate frequency signal if of the selected channel. Convert to.

The intermediate frequency amplification detection circuit 14 includes a tuner 1
The intermediate frequency signal if input from 3 is amplified and detected, the video signal p and the audio signal s are output, and the video signal p is OSD.
(On-screen display) The audio signal s is output to the RF modulator 16 while being given to the circuit 15.

The OSD circuit 15 synthesizes the video signal p input from the intermediate frequency amplification detection circuit 14 and the signals such as alphabets, numbers and characters stored in a memory (not shown) in advance to generate a video signal p '. Output to the RF modulator 16.

The RF modulator 16 includes an OSD circuit 15
Video signal p'input from the intermediate frequency amplification detection circuit 1
The audio signal s inputted from the No. 4 is converted into a specific high frequency signal r corresponding to an empty channel of the television, and then the high frequency signal r is outputted to the television receiver 10 through the output terminal 17.

The television receiver 10, after receiving and demodulating the infrared carrier signal 8 transmitted from the infrared light emitting diode 5 of the multi-remote control transmitter 1 shown in FIG. 6, wants to watch based on the infrared carrier signal 8. Change the settings of various conditions such as channel selection. Especially, when the user wants to watch the CATV, the CATV input channel is set in advance. Then, based on the high frequency signal r input from the home terminal 9 through the output terminal 17, the CAT
Play the video and audio of the V channel.

The data receiver 18 demodulates the branch signal a2 input from the distributor 12 into a data signal b and outputs it to the control circuit section 19.

The control circuit section 19 is a microcomputer composed of an electric circuit having a memory, a CPU, etc., and controls each section in the home terminal 9 based on the control contents such as the data signal b inputted from the data receiver 18. It has a central function of outputting a control signal. That is, the signal c1 input from the operation key 22 and the signal c2 input from the light receiving unit 20 are decoded, and the control signal d is output to the tuner 13 as the channel selection data of CATV broadcasting.
At the same time, the selected CATV broadcast channel is output to the CH display unit 21 as a signal f. Furthermore, addresses such as channel, volume, and audio mode for reading data such as alphabets, numbers, and characters to be displayed on the screen of the television receiver 10 from the memory of the OSD circuit 5 and the position of characters on the screen. Is output to the OSD circuit 15 as a signal e designating

The operation key 22 is located on the surface of the main body of the home terminal 9 and has keys for manually setting various setting modes as intended by the user, and various setting modes manually input to the keys. Is output to the control circuit unit 19 as a signal c1.

The CH display section 21 is composed of a light emitting diode that is displayed in two digits by two "day" character patterns, and is selected by the tuner 13 based on the signal f input from the control circuit section 19. The existing CATV broadcast channel is visually displayed using numbers and letters so that the user can read it.

The light receiving section 20 receives the infrared carrier signal 8 output from the multi remote control transmitter 1, demodulates the infrared carrier signal 8 as a signal c2, and controls the control circuit section 19
Output to. For example, the CAT of the television receiver 10
When the V input channel is set to 3 channels, the reception channel of the television receiver 10 is selected in advance by the controlled device selection key 3 of the multi-remote control transmitter 1, and the television receiver is set to 3 channels. As long as the home terminal 9 is operating, the CATV output signal r is always input to these three channels. Therefore, when the CATV is viewed, the CAT is sent to the home terminal 9 by the multi-remote control transmitter 1.
A desired CATV broadcast station can be selected by inputting channel selection channel data desired to be received in V broadcast.

[0019]

By the way, when the television receiver 10 is directly controlled by the multi-remote control transmitter 1, the manufacturer data of the television receiver 10 manufactured in advance is sent to the multi-remote control transmitter 1. It is necessary to enter it, set the code, and memorize it. However, at that time, since there is no means for displaying that the setting is completed and stored, whether or not the manufacturer of the controlled device can be correctly set is determined by actually performing remote control operation of the television receiver 10 and performing operation. It is very inconvenient because there is only a way to confirm what can be done.

Further, when the multi-remote control transmitter 1 is operated and the television receiver 10 does not operate according to the operation, it is impossible to distinguish whether the operation setting is wrong or the multi-remote control transmitter 1 is out of order. There is a problem that the procedure is lost.

The present invention solves such a problem, and when the user inputs the manufacturer of the controlled device to be used and the setting of the code is completed, the message and the setting manufacturer name are displayed on the display means. The purpose is to provide a home terminal for display.

[0022]

When the control transmitter transmits a signal for setting the manufacturer of the controlled device, the control transmitter has means for receiving the setting signal and displaying the manufacturer name on the display means.

[0023]

In this way, the home terminal receives the manufacturer setting data from the multi remote control transmitter, decodes the setting manufacturer name, and sends, for example, a manufacturer setting completion message and the setting manufacturer name to the controlled device or the terminal itself. Since the information is displayed on the display section provided in the, the user can recognize the manufacturer set in the multi remote control transmitter itself.
