Description

How to prevent overheating of fish eggs

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PCR, in which a personal computer (PC) and a VCR (VCR), which is one of home appliances, are organically coupled to accelerate the construction of a multimedia environment in a home. The present invention relates to a PCR overheating prevention method for preventing equipment damage due to overheating of a PC body during a long video watching using a sial.

The most basic form of multimedia in general is the convergence of information due to the exchange of digital information between the PC and home appliances.

Based on this concept, the Fisher System is a compound word of personal computer and Vishial. It is a form of operation that can meet the desires of personal computer (PC) and Vishal users under a multimedia environment that is gradually expanding in recent years.

The basic configuration of the digital camera includes a PC including a key input unit, a microprocessor, a data transmission / reception unit, and an overlay processing unit, a Vishal system including a key input unit, a microcomputer deck unit, VCR).

The key input unit of the finger unit includes a plurality of keys for controlling the operation of the finger, and outputs a key signal corresponding to a key operation of the user, and typically uses a keyboard and a mouse.

The microprocessor outputs a control signal corresponding to the key signal from the key input unit.

In addition, the transmission and reception unit of the microprocessor converts the code data from the microprocessor into serial code data, transmits it through the transmission line in an asynchronous manner, and uses the RS232C communication interface in general.

The overlay processing unit selectively processes video / audio signals received and processed by the vials and outputs the processed video / audio signals to a monitor and a speaker so as to output and process the edited video information, .

The microcomputer of the Vsiali outputs a control signal for controlling the operation of the Vsial agreed to the key input signal from the fish or the data from the transmitting and receiving unit, The processing unit processes the video signal and the audio signal under the control of the microcomputer.

When the user views or records video / audio of the Vicious using the television receiver on the video and the overlay board, the user can use the mouse or the keyboard of the PC to perform the functions of the Vicious, such as rewinding, fast forwarding, And the like can be controlled, and clear and clear still images can be viewed without regard to an analog method or a digital method of a desired scene.

In addition, the fish can edit and store the still image as various format information, arbitrarily change the size of the screen, move the position, and display special effects such as mosaic or multiple screens.

In addition, such a digital content can be used to perform a scheduled recording function of a specific broadcast program through the control of Vishal by the user.

1 is a flowchart for explaining a process of executing a reservation function of a television broadcast program which is a basic function of a fishery.

In the first step (1), it is determined whether or not the function key is selected by the user, and if there is a key selection, it is determined whether or not the mode key is set in the second step (2).

If the mode key is not set in the second step, the general control key input value is transmitted to the microcomputer, and the eighth step (8) is performed to determine whether or not the transmission is completed.

However, if there is an input of the mode setting key in the second step, it is determined whether the transmitted data is erroneous in the third step (3), and if the error occurs, the fifth step (5) If not, it is determined whether or not the setting completion key is input in the fourth step (4).

If the setting completion key is input in the fourth step, a fifth step of transmitting the user change value to the microcomputer is executed, and if the setting completion key input is not made, a seventh step (7) And the eighth step of judging whether or not it is necessary.

If the transmission is not completed in step 8 and the transmission is completed, then in step 9, it is determined whether the current data is a request for each mode.

Here, if the request is a request, the thirteenth step (13) of judging whether or not the received data is error is performed through the eleventh step (11) of sending the requested data value and the twelfth step (12) .

If an error occurs in the execution of the thirteenth step, the seventh step, which is the request request for each mode described previously, is executed, and if the error does not occur, after the execution of the fourteenth step (14) of displaying the changed user set value data, The process returns to the fourth step of determining whether or not the input is made.

On the other hand, if there is no request for each mode in step 10, a step 15 is executed to determine whether the user change value is transmitted to the microcomputer.

If transmission is normally performed in step 15, step 16 (step 16) is performed to determine whether an error has occurred in the received data.

If an error occurs in the received data, step 17 (17) of setting a received data error flag and step 18 (18) of setting a transmission completion flag are executed, and then the process returns to the third step.

However, if there is no received data error in step 16, the 19th step 19 of storing the received data value is executed and the process is terminated.

If it is determined in step 15 that the user value change data is not to be transmitted as a result of the microcomputer transmission, step 20 is performed to determine whether there is input of the control key value in the PC.

If there is a key value input, a twenty-second step (21) of converting the key input value into a remote key value is executed, and then the step (22) is executed to store the value in the buffer. Step 22 is executed.

After the step 22 of storing the key value data in the buffer, step 23 is performed to read the previously stored kit value, and then the data stored value of step 22 and the data read value of step 23 are compared (24). ≪ / RTI >

If the two values are the same in step 24, they are terminated as they are. Otherwise, they are stored in the buffer storage value in step 22 or are stored in the key processing RAM and then terminated.

The recording of the desired broadcast program can be scheduled and set by this process.

However, the television broadcast program reservation recording setting in the above-mentioned fish is inconvenient because the reservation program is set and registered using the auxiliary window of the fish.

For example, a reservation recording program is set by using the auxiliary window of the PC, and then the reservation data is transmitted to the microcomputer of the Vishal by pressing the data transmission key.

In order to improve this, a technique has been proposed to simplify and simplify the key operation process when recording reservation data is set up when setting a reserved recording program of a television broadcast program, and to improve the convenience in setting and controlling the function of the Vishal via the fishery There is a bar.

The improved digital content recording control technique will now be described with reference to FIG. 2, which is a circuit diagram thereof, and FIG. 3, which is a flowchart thereof.

2, the PC 100 includes a microprocessor 110 and a key input unit 120, an overlay processing unit 130, and a transmitter / receiver unit 140 coupled to the microprocessor 110.

The vise 200 includes a system controlling microcomputer 210 and a key input unit 220, a deck unit 230, a transmitting and receiving unit 240, an image processing unit 250, and a voice processing unit 260 .

The key input unit 120 in the finger 100 includes a plurality of keys for controlling the operation of the finger, and outputs a key signal corresponding to a key operation of the user, and typically uses a keyboard and a mouse.

The microprocessor 110 also outputs a control signal corresponding to the key signal from the key input unit 110.

The transmission and reception unit 140 in the microcomputer 110 converts the code data from the microprocessor 110 into serial code data and transmits the serial data to the Vishill side through the transmission line in an asynchronous manner. The transmission end TxD, the reception end RxD, An RS232C communication interface having a stage G is used.

The overlay processing unit 130 selectively processes the video / audio signal received from the Vosial according to the control of the microprocessor 110 and outputs the processed video / audio signal as a signal outputable to the monitor and the speaker, And stores it as a file in the memory device.

Meanwhile, the microcomputer 210 of the Vsial 200 outputs a control signal for controlling the operation of the Vsial agreed with the key input signal from the PC 100 or the data from the transmitter and receiver, The vise deck unit 230 and the video / audio processing unit 250.260 process the video signal and the audio signal under the control of the microcomputer 210.

The microcomputer 210 of the vial 200 receives the key input of the remote control and transmits the processed information to the fish 100 through the transmitting and receiving unit 240.

When the user views or records video / audio of the Vicious using the television receiver on the video and the overlay board, the user can use the mouse or the keyboard of the PC to perform the functions of the Vicious, such as rewinding, fast forwarding, And the like can be controlled, and reservation recording of a desired broadcast program is enabled.

The execution process will be described in detail with reference to the flowchart of FIG.

In the first step 31, the incoming data is read from the PC 100 and it is determined whether the mode is the KBPS transmission mode.

The KBPS defines a countermeasure for various matters that may occur in transmitting broadcasting signals from the broadcasting station side such as precedence, delay, cancellation, change, etc. of the broadcasting program with reference to the broadcasting program table displayed on the television screen, So that only the actual broadcast portion of the broadcast program except the advertisement and the like can be accurately scheduled to be recorded and executed.

When a user wants to record a desired program event, the program is moved to a desired program position, and then a program event is displayed on the television screen. The information is stored in the nonvolatile memory device of the Vishial.

It is possible to carry out accurate scheduled recording even if the program start time varies due to the broadcasting station.

In addition, since the current time data is transmitted, the automatic time setting and correction can be performed. In case of interruption or change of the broadcast time, the contents of the program can be reserved and executed. .

In the KBPS configuration, data for program reservation recording on a television signal is converted into digital data, inserted into a line fixed on the image vertical blanking time, and transmitted. This signal is demodulated by the decoder on the receiving side, Scheduled recording of the broadcast program and automatic time setting are performed.

In this case, the transmitted KBPS data includes the broadcast standard time information, the information of the program currently being broadcast, the name of the broadcasting station composed of seven characters, the weekly program information for one week to four weeks, classification information for each program type, Program deletion information, and the like.

On the basis of this data, KBPS has a function of displaying a broadcast order guide and a broadcast program guide, an active automatic schedule recording function at the time of power failure or change of a broadcast start time, a function of executing a scheduled program recording, A recording function, a recording data saving function, a current time automatic setting and saving function, a continuous program recording function, a program detailed guidance information providing function, a broadcasting program classification function, and a reservation content checking function.

If it is determined that the KBPS transmission mode is not the KBPS transmission mode in the first step 31, the data is terminated as it is. If the KBPS transmission mode is not the KBPS transmission mode, data stored in the microcomputer 210 of the Vishal 200 To the microprocessor 110 side via the communication port.

Then, a third step (33) of displaying the data on the basis of the transmitted data is executed, and then a fourth step (34) is executed for judging whether or not the reservation is completed.

In the execution of the fourth step, if the reservation is completed, the process is terminated, and if the reservation is not yet completed, a fifth step (35) is performed in which the KBPS data is displayed on the monitor based on the KBPS data.

In the fifth step, after receiving data of all channel broadcasting programs corresponding to one week through the internal communication of the FISH-VIS system, all programs are classified in order of classification, program order, channel order, .

Thereafter, in the sixth step 36, the user selects a desired program from the order of classification for the all programs, program order, channel order, and time order.

The key data selected in the previous step is received by the microprocessor side of the microprocessor, and the seventh step 37 is performed to convert the KBPS data into the transmission format and transmit the KBPS data to the microcomputer side of the Vishial.

Following the execution of the seventh step, the microcomputer determines whether or not there is an abnormality in the received data. If there is an abnormality, the microcomputer executes the tenth step (40) The ninth step (39) for storing and executing the received data is executed and the process is terminated.

On the premise of such a flow chart, data of all channel broadcasting programs corresponding to one week are received through communication, and the classification order, program name, channel, time date, etc. are outputted based on the data, Programs are selected and set to eight or more. After completion of the setting, the corresponding data is output to the microcomputer of VISIAR, and VISIR recognizes and executes the program, thereby performing the scheduled recording.

However, if the video tape is viewed for a long time by using the vial of such a system, the PC body is overheated by the heat generated by the power supply unit inside the PC, so that the PC constituted of the heat sensitive electronic parts is damaged or malfunctions There is a fear of causing it.

It is an object of the present invention to provide a PCR overheating prevention method which can prevent a device damage and an operation error due to overheating of a PC body when a video is watched for a long time by using a PCR combining a PC and a VCR have.

The key input unit 120 in the finger 100 includes a plurality of keys for controlling the operation of the finger, and outputs a key signal corresponding to a key operation of the user, and typically uses a keyboard and a mouse.

In addition, the microprocessor 110 outputs a control signal corresponding to a key signal from the key input unit 110.

The transmission and reception unit 140 in the microcomputer 110 converts the code data from the microprocessor 110 into serial code data and transmits the serial data to the Vsial side through the transmission line in an asynchronous manner. RxD) and a ground terminal (G).

The overlay processing unit 130 selectively processes the video / audio signal received from the Vosial according to the control of the microprocessor 110 and outputs the processed video / audio signal as a signal outputable to the monitor and the speaker, And stores the processed data in a memory device as a file.

Meanwhile, the microcomputer 210 of the Vsial 200 outputs a control signal for controlling the operation of the Vsial agreed with the key input signal from the PC 100 or the data from the transmitter and receiver, The vise deck unit 230 and the video / audio processing unit 250.260 process the video signal and the audio signal under the control of the microcomputer 210.

The microcomputer 210 of the vial 200 receives the key input of the remote control and transmits the processed information to the fish 100 through the transmitting and receiving unit 240.

FIG. 5 shows a detailed circuit configuration of the power supply unit 150 and the temperature sensing unit 270 in the hardware configuration of FIG. 4 for implementing the present invention.

As shown, the output voltage of the TV video board power supply end 152 in the power supply 150 is connected to the temperature sensing part 270 of the Vsial part through the temperature sensor 151.

The temperature sensor 151 may be a thermistor.

The reference voltage input to the temperature sensing unit 270 through the temperature sensor 151 is divided by the resistor 271 and connected to the base of the transistor 273.

The magnitude of the voltage applied to the transistor base at this time will be determined by a temperature sensor such as a thermistor whose own resistance value changes in accordance with the temperature change.

On the other hand, the transistor 273 outputs an output value corresponding to the base input at its collector side having an output resistor 272, and this output value is provided as current fish probe information to the microcomputer 210 side.

The operation of the present invention based on such a hardware will be described in detail with reference to FIG.

When the video tape is reproduced and viewed using the digital camera, independent power is supplied to the PC and the VCR, and data is linked through the transmission / reception units 140 and 240, which are RS232C communication ports .

At this time, since the Vishial is controlled through its control of the reproduction operation, the microcomputer 210 of the Vishal 200 can be notified through the execution of the step 50 of judging whether or not to perform the current Vishial reproduction operation .

Following step (51), it is judged whether or not screen shaking of the monitor of the fish is occurring.

Such a judgment can be executed automatically by the circuit of the system automatically, or it can be executed through a manual operation as a result of judgment by the viewer of the Vishal reproduction screen.

If there is a screen shake as a result of the execution of the above step, the microcomputer 210 controls the temperature sensor 270 to detect the temperature of the main body of the fish body, which is detected by the temperature sensor 151 installed on the power supply unit 150, (Step 52).

When the surer element is used as the temperature sensor 151 in the execution of the above step, if the surer element is a positive characteristic element, the resistance value changes drastically as the temperature rises, and on the contrary, The bias voltage value applied to the transistor 273 of the temperature sensing unit 270 is rapidly changed through the curve of the resistance change curve itself.

Accordingly, the voltage value output from the collector terminal of the transistor 273 is applied to the microcomputer 250 as the probe light information.

When the current temperature value of the microcomputer 210 is input to the microcomputer 210, the microcomputer executes a step 53 of comparing the current value of the microcomputer 210 with the reference temperature value set in advance.

If the measured temperature value of the current body of the body has not reached the reference temperature value set in advance, the operation returns to the first step to continuously execute the reproducing operation. If the measured temperature value of the current body of the body is preset When the registered reference temperature value is reached, the microcomputer executes the step 54 of activating the OSD 280.

Subsequently, the microcomputer executes step 55 of outputting an overheat warning message on the screen monitor in an on-screen manner via the OSD, and then stops the Vsial reproduction in step 56 and terminates.

Therefore, when viewing a video tape using a visual system, it is possible to prevent a device operation error or a function damage problem that may be caused by overheating of the main body due to long-time operation due to carelessness of the viewer.

As described above, the present invention has the unique effect of preventing excessive heat generation of the main body of the main body due to prolongation of the reproducing operation during video reproduction using PCR.
