Abstract

PURPOSE:To improve the operability by providing a designation key designating an object to be controlled a function key in common to each device to be con trolled, a storage means, a control means deciding a control code and a transmis sion means. CONSTITUTION:In receiving, e.g., the 12-channel of a TV broadcast, the depres sion of a TV key 8 is detected by a control section 12, the TV mode is stored in a storage section 13 and simultaneously, the control section 12 gives a com mand to a transmission section 14 to send a control code representing the TV sound reception mode to bring an FM stereo receiver 3 into the said mode. Then in depressing a channel key 7 representing '1', the transmission section 14 sends a control code for controlling a CATV converter represented by the '1' and a control code for FM stereo reception. In depressing a channel key 7 representing '2', since each control code representing '2' is sent, the system receives the TV 12-channel. Thus, the operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to remote control transmitters for 0ATV converters and the like.

(b) Conventional technology Figure 3 shows a schematic block diagram of an 0ATV broadcast receiving system, in which (11 is an 0ATV converter, (21 is a Tecivision receiver, (3) is an FM stereo receiver, (4) (4)
is a speaker. In this system, video signals and audio signals for multiple TV channels and audio signals for multiple radio channels are transmitted via a cable (51). While receiving the video signal of a predetermined TV channel, the FM stereo receiver (3) receives the audio signal of the TV channel, and when in FM radio reception mode, the 0ATV converter is stopped and the FM stereo receiver (3) to receive the audio signal of the FM radio channel.

Normally, the OA'I'V converter (11) and the FM stereo receiver (3) in the above system are each controlled by a remote control transmitter (6)K.

However, since the OA'I'V converter and the FM stereo receiver function independently of each other, it is necessary to control the same function key, such as a channel key, using different types of control codes. Therefore, conventionally,
When two controlled devices are controlled by one remote control transmitter, all keys required for each controlled device are provided independently, as shown in Japanese Patent Laid-Open No. 58-97967.

For this reason, for example, channel operation keys and the like are separated, resulting in poor operability and an increase in the number of keys.

(c) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned points. The purpose is to share the same.

(B) Means for Solving the Problems The present invention provides a designation key for designating a control target of each controlled device, a function key common to each controlled device, and a designation content of the designation key. A storage means for storing, a control means for determining a control code to be transmitted based on the operation of the function key and the contents stored in the storage means, and a transmission means for transmitting the control code determined by the control means. Become.

(e) Operation Even if the same function key is operated by the above-mentioned means, a different control code is transmitted depending on the controlled device specified by the specified key.

(f) Example An embodiment of the present invention will be described below with reference to the drawings.

Figures 1 and 2 are an external view and a block diagram of the remote control transmitter in this embodiment. The key (8) is the 'I'V key which turns the OATV converter (11) and the FM stereo receiver (3) into TV mode;
Radio middle-1 (Il) is a stop key that stops the operation of the 0ATV converter and the FM stereo receiver and sets the F'M stereo receiver to radio mode.

圓 is an operating section composed of the above-mentioned keys, numeral 2 is a control section composed of a microcomputer, 0 is a storage section that stores the mode selected by the operating section via this control section,
(141 is a transmitting unit that transmits a control code based on an instruction from the control unit.

Next, the operation of the remote control transmitter will be explained.

If you want to receive 12 TV channels, first select TV, ? −
(Press 81. Then, the pressing of this TV key is
13 detects the TV mode and stores the TV mode in the storage section α3. At the same time, the control unit (1z is the FM stereo receiver (3)
The transmitting section I is instructed to transmit a control code representing this mode in order to set the V audio reception mode. This puts the PM stereo receiver (3) into TV audio reception mode.

Next, select a channel. First, the channel indicating '1'' -
? - (Press 71. Then, the transmitter I transmits the control code for controlling the 0ATV converter and the control code for the FM stereo receiver, which represents 11'. Then, 12#
When the channel key (71) indicating 121 is pressed, each control code indicating 121 is similarly transmitted.

As a result, the system receives the TV12 channel.

Next, the case of receiving the 45th FM radio channel will be explained. In this case, first press the radio key (9). Then, the control unit α2 detects the press of this 2-geo key and stores the radio mode in the memory M3. Control 111 at the same time
a21#iF' In order to set the M stereo receiver (3) to the 2M radio reception mode, instruct the transmitter (14+) to transmit a control code representing this mode and a control code for stopping the 0ATV converter (1). This causes the FM stereo receiver (3) to enter the 2M radio reception mode.

Next, select a station. First, %41 channel key (7)
Press. Then, from the 41st section I, the FM representing 14"
Sends a control code for stereo receiver control. Next, press the @5# channel key (71, and press 15# in the same way)
A control code representing the

As a result, the system receives FM Radio channel 45.

When the stop key Qα is further pressed, control codes for stopping the 0ATV converter and the FM stereo receiver are transmitted, and the system is put into a stopped state.

(G1. Effects of the Invention As described above, according to the present invention, even if the same function key is operated, different control codes can be transmitted depending on the controlled device specified by the specified key, and the function key can be sent to multiple controlled devices. Since they can be made common, operability is improved and an increase in the number of keys can be prevented.
