First, the television signal receiving unit 10 receives the tuned television signal, detects and outputs the video signal V1 and the audio signal A1 from the received signal, and the compact disc player unit 30 receives the data input first. A song which outputs a video signal V2 and an audio signal A2 by reading data from at least one type of compact disc when the two control signals match by inputting the control signal C1 and the second control signal C2 input to the remote controller. It has an accompaniment function. At this time, the video signal V1 is received from the television receiver 10 to have an OSD function such as song lyrics for the song accompaniment function. In addition, the video signal processing unit 20 selectively inputs the video signal V1 of the television signal receiving unit 10 and the video signal V2 of the compact disc player unit 30 to process and process the processed signal into a CRT or LCD. Displayed through a display means such as (not shown), the audio signal processor 40 selectively inputs the audio signal A1 of the television signal receiver 10 and the audio signal A2 of the compact disc player unit 30. Signal processing and outputs the processed signal as a sound through a sound conversion means such as a speaker (not shown), the power supply unit 60 is supplied with AC power to power the TV power signal (Vtv) and the compact disc player 30 Each of the signals Vcd is generated, and the television control unit 50 sets the selected television or compact disc mode in response to a control signal input through the receiver's own control box (not shown) or the remote controller 55. Control of each part power supply over the power supply 60 and supplies the first control signal (C1) to the video signal processor 20 and the audio signal processing unit controls the signal selector (40) and a compact disc player (30).

By the way, the compact disc player integrated television receiver which improves the conventional problem operates in TV and CD operation modes. At this time, since it has two modes of operation, it is necessary to determine whether the IR signal of the remote controller 55 is a TV or CD related signal. Otherwise, they may crash and malfunction.

According to this conventional technology, a single remote control data input through an input means of a compact disc player integrated television receiver is distributed to two micoms (main micom: TV micom, sub micom: CD micom), and the distributed remote control data is stored. Each microcomputer determines the TV / CD command and executes the command. In this process, an error is caused by a miscommunication of data from one microcom (mainly a sub-microcom), which is mainly susceptible to noise due to the influence of noise, to execute a command different from the input command, or the data of both microcoms collide with each other. There is a problem that occurs.

Accordingly, an object of the present invention is to provide a remote control data reception error prevention method for preventing a reception error upon reception of a remote control signal in a compact disc player integrated television receiver.

In order to achieve the above object of the present invention, a method for preventing a remote control signal reception error of a compact disc player integrated television receiver according to the present invention includes a compact disc player integrated television including a TV micom in a television control unit and a CD micom in a compact disc player unit. A method of preventing a remote control signal reception error of a receiver, the method comprising: receiving data corresponding to a remote control IR signal from the CD receiver from an IR receiver; and receiving data corresponding to the IR signal from the TV micom at the CD micom; And determining whether the two data are the same and ignoring the two data if the two data are not the same.

Receiving data corresponding to the IR signal from the TV micom at the CD micom, receiving data corresponding to the remote control IR signal from the IR receiver in the TV micom, and determining whether the received data is CD-related data And transmitting the received data to the CD microcomputer after a predetermined time when it is determined that the CD-related data is determined.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

In order to avoid duplication of description, the same reference numerals are used.

The TV microcomputer 52 refers to a microcomputer in the television control unit 50 of FIG. 1, and performs a function of collectively controlling each part of the television receiver integrated with a compact disc player. The CD micom 32 refers to a microcomputer in the compact disc player unit 30 of FIG. 1, and performs a function of controlling each part of the compact disc player unit 30. As shown in FIG. Corresponding data according to the key selection of the remote control 55 or the control box 57 is input to the IR receiver 54 and transmitted to the TV microcomputer 52 and the CD microcomputer 32, respectively. At this time, the TV microcomputer 52 and the CD microcomputer 32 may cause mutual reception conflicts.

First, the microcomputer error prevention principle of the present invention will be described.

In the process of distributing and transmitting the IR signal transmitted from the remote controller 55 to the TV microcomputer 52 and the CD microcomputer 32, the sub-microcom having a high probability of error (in the present invention, the CD microcomputer) is an IR of the remote controller 55. In the case where the signal and the main microcomputer (TV micom in the present invention) judge the data related to the submicrocom, the corresponding command is executed only when the data transmitted to the submicrocom are compared and matched to each other, thereby executing a noise during data transmission in the submicrocom. It prevents the error operation that may occur due to the influence by.

For detailed operation, the following description will be given with reference to the flowcharts of FIGS. 3 and 4.

First, the data reception and control operation of the CD microcomputer 32 will be described with reference to FIG. 3, and the data corresponding to the IR signal received from the IR receiver 54 is received (IR corresponding data reception step 310). . Subsequently, IR-related data is received from the TV microcomputer 52 (IR-related data receiving step 320. Subsequently, it is determined whether the data are the same (data equality determining step 330). Ignore the received data (received data ignoring step 340.) If the data is the same, the CD micom 32 executes a control operation according to the received data.

Next, the data reception and control operation of the TV microcomputer 52 will be described. Then, data corresponding to the IR signal received from the IR receiver 54 will be received (IR correspondence data reception step 410). Subsequently, it is determined whether the received data is CD-related data (step 420 for determining whether the CD-related data). In the case of CD-related data, the received data is transmitted to the CD microcomputer 32 after a predetermined time elapses (received data transmission step 430). If the CD-related data is not transmitted to the CD microcomputer 32, the TV control operation is executed.

As described above, the present invention prevents a reception error upon reception of a remote control in a television receiver integrated with a compact disc player. Compared with the data received from the TV microcomputer and the data received directly from the IR receiver, if it is the same, it is treated as CD-related data. Otherwise, the received data can be ignored to prevent reception conflicts and errors.
