Abstract

PURPOSE:To fetch a new additional function not only a single function of a remote controller by incorporating a weak power radio communication equipment to a television receiver. CONSTITUTION:A switching signal transmitted from a remote control transmitter 13 enters a control microcomputer 9 through a remote control photodetection section to activate a weak power radio communication equipment 3. A weak power radio communication equipment 1 in a remote control transmitter 13 is operated by a signal switched in advance in the remote controller transmitter 13 and the remote control transmitter 13 is used for conversation through an antenna 2. Thus, the weak power radio communication equipments 1, 3 are incorporated in the remote control transmitter 13 and the television receiver 12 to connect with the control microcomputer 9 and the telephone line 5 to fetch a new additional function to the television receiver 12.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a television receiver to which digital technology is applied.

2. Description of the Related Art In recent years, television receivers have been used as various information terminal devices.

An example of the conventional television receiver mentioned above will be described below with reference to the drawings.

FIGS. 4a and 4b show the configuration of a conventional television receiver. 4 is an RF antenna.

13 is a remote control transmitter. 7 is an operation key. 1
o is a remote control light emitting section. 11 is a remote control light receiving section. 12 is a television receiver. Reference numeral 9 denotes a control microcomputer, which outputs signals for channel selection control, channel display, etc. of the television receiver 120.

The operation of the television receiver configured as described above will be explained below.

The television receiver 12, which has been powered on by the remote control transmitter 13, is tuned by a signal output from the control microcomputer 9 and enters a receiving state. The operation keys 7 of the remote control transmitter 13 are used to perform operations such as channel display 9 selection, muting, etc.

Note that the signal from the remote control transmitter 13 is transmitted from the remote control light emitting section 1o, and the signal from the remote control transmitter 13 is transmitted from the light receiving section 1 of the television receiver 12.
I'll take it in 1.

Problems to be Solved by the Invention However, with the above-mentioned configuration, only simple operations can be performed from a remote control, and there is no possibility of expansion.Therefore, a newly developed television receiver has the problem of having to incorporate new additional functions. Was.

In view of the above-mentioned problems, the present invention provides a television receiver in which a remote control has a new additional function, that is, a telephone function.

Means for Solving the Problems In order to solve the above problems, the television receiver of the present invention uses a remote control transmitter having a weak power wireless communication device function to switch between television signal reception and telephone line signal reception. Screen display when receiving telephone line signals This is a built-in low-power wireless communication device that is connected to the telephone line and transmits and receives telephone line signals.

According to the present invention, with the above-described configuration, a telephone wireless communication function is added to the remote control transmitter, and a new additional function is incorporated as a television receiver.

Embodiment Hereinafter, a television receiver according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a block diagram of a television receiver in one embodiment of the present invention.

FIG. 2 is a perspective view of a television receiver according to an embodiment of the present invention. Here, 13 is a remote control transmitter. 12 is a television receiver. A weak power wireless communication device built into the remote control 13 is used. 2 is a transmitting and receiving antenna. 3 is a weak power wireless communication device built into the television receiver 12. 4 is an RF antenna for receiving television signals. 5 is a telephone line.

6 is an on-screen display when receiving a telephone line audio signal. 7 is an operation key. 8 is a speaker. 9 is a control microcomputer. 1o is a remote control light emitting section. 11
is the remote control light receiving section. 14 is a TV tuner. The telephone line 5 is connected to a weak power wireless communication Fa3 built in the television receiver 12. The neighbor control microcomputer 9 is connected to the weak power wireless communication device 3 of the television receiver 12, the remote control light receiving section, and the television tuner 14. In the remote control transmitter 13, the speaker 8 is connected to the weak power wireless communication device 1 inside the remote control transmitter 13. The operation key 7 is connected to the weak power wireless communication device 1 in the remote control transmitter 13 and the remote control light emitting section.

The television receiver configured as described above will be explained using FIGS. 1, 2, and 3.

FIG. 3 is a flowchart regarding the operation of the television receiver of the present invention.

When the weak power wireless communication device 3 to which the telephone line 6 is connected receives an audio signal from the telephone line 6, the control microcomputer 9 outputs the TV audio mute and on-screen display 6 signals when receiving the telephone line. . When the user learns that a telephone line signal has been received, he switches between TVIL reception and telephone line signal reception using the operation key T of the remote control transmitter 13. The switching signal transmitted from the remote control transmitter 13 enters the control microcomputer 9 through the remote control light receiving section, and operates the weak power wireless communication device 3 of the television receiver 12.

Also in the remote control transmitter 13, the weak power wireless communication device 1 in the remote control transmitter 13 is operated by the signal switched earlier, and a conversation can be performed using the remote control transmitter 13 through the antenna 2. When the telephone wireless communication is completed, the operation key 7 of the remote control transmitter 13 is used to return to the television reception state.

Note that even when the television is not being received, the control microcomputer 9 outputs a signal to turn on the television receiver 12 when receiving a telephone line signal, and the same operation thereafter enables wireless telephone communication.

As described above, according to this embodiment, the remote control transmitter 13 and the television receiver 12 incorporate the weak power wireless communication devices 1 and 3, and are connected to the control microcomputer 9 and the telephone line 6. New additional functions can be incorporated into the television receiver 12.

Effects of the Invention As described above, according to the present invention, by using a remote control transmitter having a weak power wireless communication device function, it is possible to switch between television signal reception and telephone line signal reception, and to change the telephone screen display when receiving a telephone line signal. Performs wireless communication and is connected to a telephone line,
By incorporating a low-power wireless communication device that transmits and receives telephone line signals into a television receiver, it is possible to incorporate new additional functions in addition to the single function of a remote control.
