Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention provides a remote control transmitting/receiving device which multi-functions the input key of a transmitter and enables transmission of many signals.

BACKGROUND TECHNOLOGY Many video/audio devices incorporate a remote control transmitting/receiving device so that they can be operated from a remote location, and as the transmission content becomes more complex, the number of keys provided in the transmitter 1c is increasing. be. However, in conventional remote control transmitting/receiving devices, the key on the transmitting section is /key/function, so the more functions it has, the more the number of keys increases, and the density of the keys on the transmitting section increases. It had some drawbacks, such as sluggish operation. In particular, TV JOY reception, which can receive teletext broadcasts, is like a machine, and viewers use it to get essential information from the received teletext broadcasts. Since a large number of keys must be provided, the transmitting section inevitably becomes large, and there are drawbacks such as the inability to convert it into a co/bact.

DISCLOSURE OF THE INVENTION The present invention eliminates the above-mentioned drawbacks, and includes a receiver that receives signals sent from a transmitter, which is connected to a plurality of receiver circuits via an interface circuit, and a receiver that receives signals sent from a transmitter. An object of the present invention is to provide a remote control transmitting/receiving device in which a receiving circuit corresponding to a specific input signal is connected to an interface circuit, thereby making it possible to make the keys of the transmitting section multifunctional. .

In order to achieve this object, the present invention includes a transmitter that is provided with input keys of + and =a and that transmits an input signal corresponding to the operated input key, and a transmitter that transmits the input signal that the transmitter transmits. A receiving unit that receives data remotely; 1. It consists of a plurality of receiving circuits connected to the cough receiving section via an interface circuit, each of which shows a different response to the received input signal, and the front interface circuit receives one fixed input from the transmitting section. It is advantageous to have a structure in which the signal path 51 is turned off so that a predetermined receiving circuit is selected in accordance with the signal.

According to the present invention, since the plurality of receiving circuits connected to the receiving section via the interface circuit are configured such that a predetermined receiving circuit is selected in response to an 11"q constant input signal from the transmitting section, (Even without changing the number of input keys provided in the i section, the functions of the input keys can be multifunctionalized by the number of reception circuits. Therefore, even if the same key operation is performed, the functions of the input keys of the selected reception circuit For example, by using it for remote control of video/audio equipment, even if the number of input signals required for remote + qh operation increases, the size of the transmitter and To achieve excellent effects such as being able to provide a compact and easy-to-use transmitter without changing the manual key 00 or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode for carrying out the invention and embodiments of the invention will now be explained with reference to the drawings. FIG. 1 is a schematic configuration diagram showing one embodiment of the remote control transmitting/receiving device of the present invention, FIG. 2 is a plan view of the transmitter 1ci shown in FIG. 7, and FIG. 3 is the diagram shown in FIG. This is 70-year-old Hinuma to explain the supporting work of the interface circuit.

Is it a person's key for selecting one station in this embodiment? There's no hawk! 3.
In addition to supporting / to 12 channels, / or 6
Input representing numbers up to 9, heron, 'o'.

This corresponds to the input represented by A. 'ni' is for specifying a program in teletext broadcasting, 'θゞ is a zero representation of a number, and 〈se' is for specifying a page within a program in teletext broadcasting. These input keys and '+2' are the seven keys that perform two functions, but as will be explained later, the input keys /'+2 are used to specify the reception of teletext broadcasting.
One of the functions can be selected by pressing </ or by rolling the television broadcast key 13.

Interface circuit! is connected to a key matrix type matrix circuit ja, which functions to interpret the signal received by the receiving section 1 according to a predetermined logic and distribute it to the receiving circuit 2 or 7.

If you want to receive teletext, press the +[1+]M key 23, then press the television broadcast input key -13.
Press. When the receiving section receives the information that the human key 13 has been processed, it transmits a signal to the interface circuit j', and the interface circuit j' puts the receiving circuit into a receiving state. Therefore, at step /θ/ shown in FIG. 3, the television broadcasting mode is entered, and as a result, the input key is pressed.

If you press , enter key 鵠.

is processed as a signal representing channel 10. After the desired channel has been selected in this way, when the input key 11A for teletext reception is pressed, the interface circuit is activated according to the judgment result in step 10.2. ! puts the receiving circuit 7 into the receiving state. As mentioned above, this receiving circuit 7 is a circuit that receives commands related to the reception of teletext broadcasting, and for this reason, an input key is sent. ,
and +1 + 'It &'L, respectively “≠ゞ ＃O
It has input functions represented by ", s#", and the input keys -/I to ? and FI become numeric keys.

Therefore, after the teletext mode is selected in step 103, if you press the key repeatedly, for example 3#1 on 17, for teletext broadcast on the already designated channel, @7 in the designated channel will be displayed. The third negative teletext of the program can be selected.

Also, in the teletext mode, if the person key 13 is pressed, the television broadcast mode is selected again according to the 111 disconnection result in step IO'l, and the step /
As a result of returning to θ/, the input oyster is -J'1! ,.

The key now functions as an input key for channels corresponding to channels / to 12.

As explained above, according to the remote control transmitting/receiving device/having the above configuration, a plurality of receiving circuits 6 and 7 connected to the receiving section 3 via the interface circuit j are connected to a specific input signal of the transmitting section 3. Since the configuration is such that the predetermined receiving port 1!8g or 7 is selected in response to the
And, even if the number of /12 is not changed, the receiving circuits 6 and 7
Insert as many oysters as 4 or 1. It is possible to make the functions multi-functional, so even the same key operation can have different tastes and tastes depending on the selected receiving circuit. By using it as a remote control function, even if the number of input signals required for remote control is large, the size of the transmitting section 30 and the number of input signals required for remote control can be increased. , No! 3. A compact and easy-to-use transmitter 3 can be provided without changing the number of transmitters 3 and the like.
