The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the gist of the present invention will be described.

Basically, there are many types of remotes (modes), and each remote uses a different format of signal (although there are some classes of remotes that use signals of some similar format, which are considered the same mode). The format of each remote control signal has a change in signal level (Edge), and the period (time) between each pulse and the number of pulses are defined with different values for each format. In addition, each pulse that is sequentially generated has a unique period (range).

In this case, in the present invention, the term timing is used as a concept including a period between each pulse and a period of each pulse as described above.

Meanwhile, in the present invention, the timing pattern of each remote control signal is measured in advance, and the timing pattern is stored for each mode (type) (additionally, the number of pulses may be additionally measured and stored). The timing is measured (in addition, the number of pulses may be additionally measured) and sequentially compared with the previously stored timing patterns to determine the type (mode) of the remote control signal.

At this time, by additionally ranging the period data of each pulse according to the maximum and minimum values (receiving margin range), there is a slight error in the timing measurement process of the input remote controller signal, even though it is the same as the previously stored timing pattern. It is possible to prevent the error of discriminating by different remote control signals. This can be adjusted so that the user maintains an appropriate reception rate by changing the reception margin range through the key operation section.

1 is a diagram illustrating an example of a decoder for analyzing and determining a remote controller signal to which the present invention is applied.

As shown in FIG. 1, a decoder (ie, a remote controller signal analyzing and determining apparatus) to which the present invention is applied includes a liquid crystal display (LCD) 14, a remote controller signal receiving unit 11, The key operation part 12, the power supply part 15, etc. are included.

The remote control signal receiving unit 11 receives a waveform of a signal transmitted from the remote control unit and inputs it to the micom 13, and the liquid crystal display unit 14 displays remote control data that is determined and output from the microcomputer 13. Display the same output data to the user.

The key operation unit 12 may input a user input signal for changing from manual mode to automatic mode or setting from automatic mode to manual mode, and a user input signal for changing a reception margin. Enter

The microcomputer 13 is a core component in which the present invention is performed. After measuring the timing of each remote controller signal input through the remote controller signal receiver 11 in advance, the microcomputer 13 stores timing patterns for each mode (type), and then, in real time. By measuring the timing of the remote control signal input through the remote control receiver 11, and sequentially comparing with the previously stored timing pattern to determine the type of the remote control signal, the remote control data according to the determination result is displayed in the liquid crystal display unit ( 14) In addition, the microcomputer 13 receives an automatic / manual mode change signal or a reception margin change signal input through the key manipulation unit 12 and performs a corresponding function.

The power supply unit 15 functions to supply power required for each component as described above.

2A to 2C are exemplary views illustrating transmission waveforms of a remote control signal according to the present invention.

For example, as shown in FIG. 2A, the first timing is 8.9 ms as a lead code. Then, a custom code, a data code, and the like are input at the next timing. Here, the timings of the data "0" and "1" are stored in the microcomputer 13 as 1.125 ms and 2.25 ms, respectively, as shown in FIG. 2B. As shown in FIG. 2C, the frame interval is 60 ms. On the other hand, the number of pulses (number of pulses) at the end of one frame is also stored in the microcomputer 13 so that a transfer format differing only by the number of data at the same timing can be distinguished.

3 is a flowchart illustrating a method for determining a remote controller signal analysis according to the present invention.

First, the timing of each remote controller signal input through the remote controller signal receiver 11 is measured in advance, and the timing pattern is stored for each remote controller mode (type) (31). At this time, the number of data (number of pulses) is additionally measured and stored.

A detailed embodiment of the process 31 will be described in detail with reference to FIGS. 4A through 4D. When the remote controller signal to be measured and stored in advance is input through the remote controller signal receiver 11, the microcomputer 13 sets its own timer. The timing of the remote control signal is measured for each edge, and the timing pattern is stored in a ROM area of its storage device as shown in FIG. 4A. As a specific example, timing data (pattern) is stored for each type of remote controller (mode) in the mode search table as shown in FIG. 4B. Then, the mode display data of the corresponding remote control signal is stored in the mode display table as shown in FIG. 4C. In addition, data for determining whether the remote control input signal is "0" or "1" is stored in the data table as shown in FIG. 4D in comparison with the timing of the remote control input signal.

Thereafter, when the remote controller signal to be determined is input through the remote controller receiver 11 in real time, the timing of the remote controller signal is measured and stored (32). That is, each time the remote control signal is input, the timing between each falling edge is measured using the internal timer of the microcomputer 13 and then stored in the internal RAM in order. At this time, the number of data (number of pulses) is additionally measured and stored.

A detailed embodiment of the process 32 will be described in detail with reference to FIGS. 4A and 4E. When the remote controller signal to be analyzed and determined is input through the remote controller signal receiver 11, each microcomputer 13 uses its own timer. The timing of the remote control signal is measured for each edge, and the timing pattern is stored in a RAM area of its storage device as shown in FIG. 4A. As a specific example, timing data (pattern) of the remote controller signal measured as described above is continuously stored in the RAM region as shown in FIG. 4E. In this case, when the measured timing data is stored in the RAM, if the remote controller signal exceeds the capacity of the internal RAM or is not input for a predetermined time, the process proceeds to the next step 33.

In this process, the type of the input remote control signal is determined by sequentially comparing the timing pattern previously stored in the ROM for each type of the remote control with the timing pattern of the determination target remote control signal stored in the RAM (33). That is, the timing data for each edge is satisfied by sequentially comparing whether the timing data of each edge stored in the RAM has a value within the minimum and maximum time in the corresponding edge section among the timing data stored for each type in the ROM. The remote controller mode (type) is determined by the type of the input remote controller signal. At this time, the number of data of one frame may be additionally compared and used to determine the type of remote control signal.

Looking at the embodiment of the process 33 in detail, first load the first timing data (lead code) stored in the RAM and the first timing data of the first mode already stored in the ROM (mode search table of Figure 4b) If the comparison is within the minimum and maximum values, the second timing data stored in the RAM is loaded and compared with the second timing data of the first mode already stored in the ROM (the mode search table of FIG. 4B). If it is not within the maximum value, the process proceeds to the comparison with the first timing data of the second mode. In this way, if there is a remote controller mode (type) that compares the two timing data sequentially and satisfies all the timing data stored in the RAM, the mode is determined as the type of the input remote controller signal, and all the data are compared to the last data. If there is no mode that satisfies, an error message is displayed.

Next, the type (mode) of the determined remote control signal is displayed (34). For example, if the mode of the remote control signal is determined as the mode 003 of FIG. 4B in the previous process 33, the mode display data C20D6-03 of 003 is read and displayed in the mode display table of FIG. 4C.

Next, the timing of the remote controller signal transmitted and input from the remote controller is measured, and the input remote controller signal is compared with the data (data of the determined mode) of the corresponding address (eg, 003) of the data table (eg, FIG. 4D). 0 and 0 are determined and displayed (35). That is, the timing data of the input remote controller signal is compared with the previously stored timing data of the determined remote controller mode to determine whether the remote controller input signal is "0" or "1".

In this case, in order to prevent an error that is determined by different remote control signals even though the timing patterns are the same because there is a slight error in the timing measurement process of the remote control signals, the proper reception rate may be maintained by changing the reception margin range. That is, if the reception margin (timing data of the received remote control signal) comes within the reception margin range of the maximum range and the minimum range, it is regarded as a valid value. For example, when the timing of "0" is 1ms and the timing of "1" is 2ms, it is 1ms as comparison stored data (comparing timing data in FIG. 4D) for distinguishing "0" and "1". You can use 1.5ms, which is the median between and 2ms. When the minimum range is 0.5 ms and the maximum range is 3 ms, the reception value between 0.5 and 1.5 ms is determined to be "0", and the reception value between 1.5 ms and 3 ms is determined to be "1". By appropriately adjusting this receiving margin range, the error range can be adjusted.

On the other hand, in the step 33 of determining the type of the input remote control signal by sequentially comparing the timing pattern previously stored in the ROM for each remote control type and the timing pattern of the determination target remote control signal stored in the RAM, Timing data for each edge is satisfied by comparing the timing data for each edge stored in each ROM with the minimum and maximum time in the corresponding edge section among the timing data stored for each type in the ROM. The remote controller mode (type) may be determined as a type of the corresponding input remote controller signal, and at the same time, a plurality of similar remote controller modes (types) may be determined together and displayed together in a later process 34.

When the remote controller mode (type) of a similar type is displayed as described above, the controller proceeds to the next process 35 after receiving a remote controller mode selection signal from the user and further performing a process of selecting the remote controller mode (not shown). .

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

The present invention as described above, by analyzing the transmission content, such as the format (Format) and key data (Key Data) of the remote control signal commonly used as a remote controller, by configuring the decoder (Decoder), it is possible to improve the convenience and accuracy It can greatly improve.

In addition, the present invention can be configured so that Micom automatically finds and displays the transmission contents of the remote controller, thereby increasing the reliability and greatly reducing the time required for analyzing the format and key data of the remote controller signal.

In addition, since the present invention is displayed in a digital form on the liquid crystal display (LCD), accuracy can be compared with the conventional method of checking a waveform with an oscilloscope.

In addition, the present invention can accurately compare and analyze even a transmission form of a similar form.
