For further understanding the above-mentioned object of the present invention, function, feature and advantage, hereafter cooperation institute accompanying drawings is further illustrated preferred embodiment of the present invention.
Fig. 3 system shows the process flow diagram of the interpretation method of the infra-red remote control instruction of one embodiment of the invention, for convenience of description interpretation method of the present invention, is all to illustrate for NEC code in Examples below, but is not limit the present invention.
After infra-red remote control instruction sequence code input (reception), step 301 first detects the initial pulse wave of sequence code, generally speaking, the pulse bandwidth of the initial pulse wave of infrared ray instruction sequence code is the several times of the pulse bandwidth of data pulse wave, therefore, when the pulse bandwidth detecting a pulse wave in sequence code exceed data pulse bandwidth a lot of time, can judge that this pulse wave is initial pulse wave, for NEC code, the pulse bandwidth of the initial pulse wave of NEC code about 9 milliseconds, and the pulse bandwidth of data pulse wave about 0.56 millisecond, therefore, if the pulse bandwidth detected (during high levels) is more than a default value (such as 2 milliseconds), then judge that this pulse wave is as initial pulse wave.
In step 302, be calculate the sample period in order to coding sequence code.After the initial pulse wave of confirmation, calculate the pulse bandwidth of the data pulse wave that initial pulse wave occurs below, and by this pulse bandwidth as the sample period in order to coding sequence code data position.In the coded format of NEC code, the pulse bandwidth (during high levels) of its data pulse wave is fixing, binary " 0 " or " 1 " place value is represented respectively during being generally change low level, therefore, the sample period i.e. pulse bandwidth (during high levels) of each sequence code bit, namely 0.56 millisecond, if the waveform of sequence code produces distortion because of transport process, then step 302 can calculate the pulse bandwidth after distortion, and using this pulse bandwidth as the sample period of decoding.In one embodiment, the sample period is that the pulse bandwidth calculating first data pulse wave that initial pulse wave occurs below obtains.
In step 303, the sample period obtained with step 302 carries out decoding to the data bit (i.e. data pulse wave) in sequence code, and namely meaning carries out judging binary " 0 " or " 1 " place value representated by user code in sequence code or data code bit.In the present embodiment, step 303 detects interval in sequence code between every two pulse waves (in such as sequence code, the falling edge of a data pulse wave is to the waveform rising edge of adjacent pulse wave) institute through sample period number according to the sample period, with the place value of identification corresponding to it, please refer to the schematic diagram shown in Fig. 4 (a), it is be described for the data bit of NEC code, when detecting the interval between two pulse waves and being less than 2 sample periods, this position represents binary " 0 ", as shown in Fig. 4 (b), when detected result is more than or equal to 2 sample periods, namely this position represents binary " 1 ".In another embodiment, the rising edge also can detecting a data pulse wave according to the sample period to the rising edge of adjacent pulse wave or falling edge the sample period number of process judge representated by this data bit place value.In interpretation method of the present invention, the sample period of decoding institute foundation produced by the actual pulse bandwidth received, even if infrared ray instruction sequence code has the situation that waveform distortions occurs at transport process, under normal circumstances, pulse wave distortion is equal proportion, therefore, the sample period produced with the pulse bandwidth after being out of shape is used as the foundation of decoding, still can obtain correct decode results.
Fig. 5 display is according to an embodiment schematic diagram of the code translator of infrared control instruction of the present invention, and as shown in Figure 5, code translator 500 of the present invention comprises detecting unit 510, determining means 520 and a decoding unit 530.Detecting unit 510 is used to the initial pulse wave detecting sequence code, and whether it detects the pulse bandwidth of pulse wave in sequence code more than a default value according to a frenquency signal, if the pulse bandwidth detected exceedes this default value, then judges that this pulse wave is as initial pulse wave.For the difference of beginning pulse bandwidth and data pulse bandwidth from tomorrow NEC code, in NEC code, pulse bandwidth during initial pulse wave high levels is 9 milliseconds, and data pulse bandwidth is 0.56 millisecond, therefore, when the pulse bandwidth of a pulse wave in sequence code exceed data pulse bandwidth (0.56 millisecond) a lot of time, can determine that this pulse wave is initial pulse wave, in the present embodiment, default value is set to 2 milliseconds, when detecting unit 510 detects the pulse bandwidth of a pulse wave more than 2 milliseconds, namely detecting unit judges that this pulse wave is as initial pulse wave, after detecting unit 510 detects an initial pulse wave, a notice signal INIT_PS can be produced, in order to notify determining means 520 and decoding unit 530.
