The present invention relates to a data processing apparatus of an integrated remote controller and a data processing method of the integrated remote controller using the same, and more particularly, in order to overcome the disadvantages of the universal type and the learning type remote control. The present invention relates to a hardware type remote controller data processing apparatus used in a hybrid type integrated remote controller that can be collected, and a method of processing data using the apparatus.

In order to increase user convenience of products such as home appliances, home networks, and PCs, the trend of using an infrared remote controller (hereinafter referred to as a remote controller or remote controller) as a peripheral device has been spreading. Expansion is accompanied.

Integrated remote control is called multi type, which is separated from simple type, which is a limited type of control. It is a remote control that can control products such as various home appliances with one remote control. It is divided into download type and learning type universal type.

The universal type has a drawback that it cannot support all products because it is not registered and stored in its own database for new products. Therefore, the learning type and PC link download type are in the spotlight.

1 is a diagram illustrating a data structure of a remote controller. As can be seen from Figure 1, the data structure of the remote control signal is composed of a leader code (Customer Code), a custom code (Custom Code) and a data code (Data Code), etc., the learning type (LR) A digital data structure having the structure as shown in FIG. 1 input from an external remote controller using an external infrared receiver circuit extracts, stores and reproduces the approximate data through a timer and a counter.

However, the learning type has a disadvantage in that the learning quality (receipt rate and reception quality) of the data received from the external remote controller is very low and has a considerable amount of error compared to the supported data.

In addition, all the conventional remote controllers, including the PC linked download type, are used by software processing methods, so the number of CPU interrupts is inevitably frequent, which may affect the quality of the CPU. If the CPU performance is not good, the data processing speed is slow.

Therefore, there is a need to present a hybrid integrated remote control data processing apparatus and method that improves the problems of the universal type using previously stored data and the existing learning type that downloads new data or receives and processes data from an external remote controller. to be.

In order to minimize the problem of not operating, that is, the conventional remote control chip is implemented as a hardware IP with minimal use of the CPU interrupt to prevent the problem that the conventional remote control data processing method which is supported as software depends on the performance of the CPU. It is the purpose to be comprised in (CHIP).

It is a further object of the present invention to provide an apparatus and method capable of handling both data types on a carrier frequency and those not, supporting all remote control communication protocols.

In order to achieve the above object, the data processing device of the integrated remote controller according to the present invention, an infrared signal converter 110 for receiving an external infrared signal when receiving an infrared signal, removing noise and converting the signal into a voltage form ); A square waveform generator 120 generating square waves through the signal from the infrared signal converter 110 upon receiving an infrared signal; When the infrared signal is received, it has a function of repetitively extracting high and low level times several times by timing counting from the square wave generated by the square wave generator 120, through interaction with the carrier 220.

A timing processor 210 including a function of generating; When the infrared signal is received, the data extracted by the timing processor 210 is stored and transmitted to the CPU 300.

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

The device according to the present invention basically checks whether there is corresponding data in the memory unit that stores certain data of the remote controller when receiving data through an external device, and if there is such data, the device stores the data stored in the memory unit. If there is no corresponding data, the information of the data can be accurately extracted and used. However, since the data information is extracted by the software method from the existing learning type remote controller, the speed processing is delayed or the data of It is to provide a device that can extract and utilize more rapid and accurate data by having a dedicated hardware component for this without the problem that the error is increased through artificial deformation.

Figure 2 is a block diagram showing the configuration of the components constituting the device according to the present invention. As can be seen from Figure 2, the apparatus according to the present invention is an infrared transmission and reception unit 100 for transmitting and receiving infrared data and logic for extracting the data required when receiving a signal and a rectangular waveform suitable for the transmission of the signal The timing controller 200 includes a memory unit 400 and a CPU 300 capable of storing a predetermined amount of data information such as a remote controller or a home appliance, and additionally storing new data.

The infrared transceiver 100 includes an infrared signal converter 110 and a square wave generator 120 having a basic function of transmitting and receiving an infrared signal, and the timing controller 200 is a timing processor. 210, a level time processor 230, a carrier 220, a clock input 240, and a function controller 250.

When the infrared signal converting unit 110 receives the remote control data of the device for remote control of the external device, it receives a current input of an external photo diode to remove noise and converts the voltage into a voltage type. In this way, it converts the signal received from the outside into the form required for the integrated remote control.

When the square waveform generator 120 receives a signal from the outside, the square waveform generator 120 removes noise from a signal converted by the infrared signal converter 110 and converts the square waveform to a square waveform for digital processing. Do this. As will be described later, when the signal is transmitted, the timing processor 210 directly interacts with the carrier 220 to receive the data received from the level time processor 230 by the command of the CPU 300 to directly generate a desired infrared square wave and transmit and receive infrared rays. Since the output to the unit 100, the square waveform generating unit 120 actually performs only the infrared signal receiving function.

The timing processor 210 extracts accurate high to low level time through signal synchronization and timing counting through the generated square wave upon receiving data, and interoperates with the carrier 220. The core component of the present invention performs a basic function of extracting the most suitable carrier frequency among carrier frequencies included in the square wave data when the square wave is identified as a carrier frequency type. to be.

In general, there are two types of transmission protocols of the remote controller: modulation through a carrier (NTSC broadcast area) and data transmission without a carrier (PAL broadcast area). Thus, the received data (signal) may not be a carrier type unconditionally. Therefore, the carrier type and the other case should be determined by a certain logic to perform the corresponding operation, and the timing processor 210 performs the discrimination and processing functions accordingly.

In order to extract the correct data with respect to the received signal, the timing processor 210 repeatedly extracts data until the same carrier frequency is continuously extracted. In general, the data at the first reception has an error between carrier information. For example, if a repeated extraction operation is performed at least 10 times, the carrier is continuously input without error, and thus the data is repeatedly compared with a constant repetitive data extraction and storage. The optimal carrier frequency data is extracted by updating the data, and the accurate extraction of the carrier frequency dictates the precise reception rate. The extraction of the carrier frequency by the conventional software method uses the CPU separately so that the processing speed becomes slow. In addition, there is a limit of the repetitive processing task. The function of the hardware type timing processor 210 may overcome the disadvantage of the existing software processing method.

In addition, the timing processor 210 determines whether or not to carry a carrier according to the two types of protocols at the time of data transmission, and also after high to low level time analysis by interaction with the carrier 220. Data the level time. In addition, when the signal transmission is not the carrier type frequency, it performs a function of generating a rectangular waveform through the high and low time level time received from the level time processor 230, and in the case of the carrier frequency type level time processor ( 230 to generate a rectangular waveform through the low time level time received from. In the high level time generation, the carrier frequency is generated in conjunction with the carrier unit 220 to generate an output waveform according to the high level.

Specifically, the timing processor 210 first extracts the high to low level time of the data represented by the square wave and transmits it to the level time processor 230. When the data is a carrier frequency type, the timing processor 210 determines the total time of carrier frequencies. If the transmission time is transmitted to the level time processor 230 at a high level time and is not a carrier frequency type, the extracted high to low level time is transmitted to the level time processor 230 and a flag is set to the function controller 250. flag setting).

As a result, the timing processor 210 repeatedly calculates the high to low level time of the received signal and repeatedly checks whether the carrier is a carrier type, and precisely extracts data according to each type, thereby leveling the processor 230 to the CPU 300. It will serve to transmit or store the data.

The level time processor 230 interacts with the timing processor 210 for data transmission and storage. When the timing processor 210 finishes the timing process when the signal is received, the timing data is converted into a hexadecimal format. The data is stored as data and transmitted to the CPU 300 under the control of the function controller 250. At the time of signal transmission, data required by the timing processor 210 is received through the memory unit 400 by the CPU 300.

The carrier unit 220 is a component that is interlocked with the timing processor 210 for detection of a carrier frequency. The carrier unit 220 includes general information on a basic carrier frequency type to select whether a signal type is a carrier frequency type and receives a signal. In this case, the timing processing unit 210 assists a function of searching for the type of carrier frequency and extracting data according to the presence or absence of the discrimination, and at the time of signal transmission, the level time under the command of the CPU 300 in the case of the carrier frequency type. The high level time data received from the processor 230 directly generates an infrared square wave carrying a carrier frequency type and outputs the infrared square wave to the infrared transceiver 100.

The clock input unit 240 basically has a function of generating one timing unit of the timing processor 210. For example, assuming that one clock unit is 1 second, the clock processor 240 counts 256 times of the corresponding data. If it is, the level is 256 seconds, and the reason for generating the timing unit is that the timing unit varies considerably according to the type of external remote controller to receive data, and thus the clock unit needs to be adjusted.

The function control unit 250 includes a circuit which can basically control the data processing performing function of each component of the timing control unit 200, and is configured to display a status of such a procedure.

The extracted optimal data is transferred to the CPU 300. The CPU 300 analyzes this data and if the data matches the data previously stored in the memory unit 400, the CPU 300 prescribes the data. Command to use the data of the memory unit 400 is stored as it is, otherwise new data is stored in the memory unit 400.

According to the function of these components, the integrated remote control data processing method according to the present invention is as follows.

3 is a flowchart illustrating a process for a method of processing integrated remote control data upon receiving an external signal according to the present invention.

In the infrared signal reception mode, a clock unit is set from the CPU 300 through the clock input unit 240 and a start bit through the function control unit 250 (S10).

The signal received through the photodiode is converted into a signal of a voltage form after a certain noise is removed through the infrared signal converter 110 (S20) and removes an inadequate signal through the square waveform generator 120. A square wave is generated later (S30).

Next, the timing processor 210 analyzes and counts the generated square wave, and counts the high level time and the low level time of the square wave, extracts the corresponding timing, and stores the timing in the level time processor 230. S40)

Thereafter, the timing processing unit 210 and the carrier unit 220 interoperate and search whether the received signal is a carrier frequency type (S50). This process is to determine whether the carrier frequency type is more accurate and the accuracy of data reception. In order to achieve this, a series of repetitive processes are performed several times, and this repetitive task may be repeated several times until the optimal data is extracted.

When the received signal is a carrier frequency type, the entire time for the carrier frequency input is stored in the level time processor 230 as high level time data, and the time without input is stored in the level time processor 230 as low level time data. Save. (S60)

After that, since the first extracted carrier frequency data may have many errors, optimal data need to be extracted, and the data processing method of the present invention has a step (S80) of checking this, that is, accuracy for the carrier frequency type. After the continuous carrier frequency is extracted until the optimal data is obtained, the stored data is compared and updated several times (S90). Does not perform any more and stores the high level time and the low level time of the final carrier frequency in the level time processor 230 and transmits them to the CPU 300 (S100).

If the received signal is not the carrier frequency type, the extracted high level time and low level time are stored in the level time processor 230, and a flag set is performed in the function controller 250 (S70). After checking whether the data is also optimal (S80), otherwise, comparing and analyzing the data again and updating (S90), and when it is determined that the optimal data is finally stored in the level time processor 230, The CPU 300 transmits the data to the CPU 300 (S100).

After the final data on the carrier frequency presence type is extracted, the CPU 300 determines whether the level time data transmitted from the timing processor 210 to the CPU 300 is stored in the memory unit 400 ( S110), in the case of new data, the CPU 300 stores the data in the memory unit 400 in an appropriate format based on the received information (S120), and when the data is identical to the previously stored data, the CPU 300 stores the data previously stored in the memory unit 400. (S130)

4 is a flowchart illustrating a process for an integrated remote control data processing method in transmitting a signal according to the present invention.

In the signal transmission or transmission, in the case of transmitting the existing data, the data stored in the memory unit 400 may be transmitted as it is, and in the case of the new data, it is a basic process to utilize the data stored in the memory unit 400 newly. There is a characteristic of generating a corresponding output waveform by determining whether or not to carry a carrier frequency according to the carrier frequency type, and the process will be described as follows.

When switching from the above-described infrared signal reception mode to the transmission mode, the clock unit from the CPU 300 through the clock input unit 240 and the necessary information through the function control unit 250 is set (S210).

Next, the data stored in the memory unit 400 is transmitted to the level time processor 230 by the command of the CPU 300 to output and transmit the level time data (S220).

The process of checking whether the data is the carrier frequency type is performed (S230). If the output and the data to be transmitted are set to the carrier frequency type, the carrier unit 220 timing the carrier frequency during the high level time of the level time processor 230. The output waveform is generated in cooperation with the processor 210 and the low level time data of the level time processor 230 is sent to the timing processor 210 to generate an output waveform (S240).

If the output and the data to be transmitted are not set to the carrier frequency type, the timing processor 210 generates data of the high level time and the low level time of the level time processor 230 instead of the carrier frequency type as output waveforms. S250)

In this manner, when the signal is transmitted, the output waveform is generated through the carrier 220 or the timing processor 210 without passing through the square waveform generator 120.

The generated output waveform is transmitted to the infrared transceiver 100 to be transmitted and output to the outside (S260).
