The embodiment of the present invention is described in detail by taking chip UPD6121G as an example below.
Remote controler generallys use the chip of model UPD6121G as infrared remote coding chip.
Fig. 6 shows the waveform diagram of " 0 " and " 1 " of UPD6121G chip, and referring to Fig. 6, UPD6121G chip is used
The serial code of pulsewidth modulation, with pulsewidth be 0.565ms, the combination of interval 0.56ms, period for 1.125ms indicates binary
"0"；It is 0.565ms with pulsewidth, the combination of interval 1.685ms, period for 2.25ms indicates binary " 1 ".Above-mentioned " 0 " and
32 binary codes of " 1 " composition carry out secondary modulation through the carrier frequency of 38kHz to improve emission effciency, reach reduction power supply power consumption
Purpose.Then, then by infrared-emitting diode infrared ray is generated to spatial emission.
With reference to Fig. 1 and Fig. 6, the remote control coding that UPD6121G is generated is continuous 32 binary system code characters, including drawing
Leading code, 16 CUSTOMER IDs (also referred to as customer number) are including 8 CUSTOMER IDs and 8 CUSTOMER IDs
(radix-minus-one complement), 16 operation codes (also referred to as numeric data code, key value, function code) are including 8 operation codes and 8 operations
Code (radix-minus-one complement)；CUSTOMER ID prevents different machine remote control modes from interfering with each other, citing comes for distinguishing different electrical equipments
It says, the CUSTOMER ID of UPD6121G chip is fixed as hexadecimal 01H；Operation code is for indicating remote controler key assignments.
The coding of the most 128 kinds of various combinations of volume of UPD6121G chip.
It is common, when remote controller key is pressed, can trigger remote controler (by taking UPD6121G chip as an example) periodically or
It is acyclic issue it is a kind of include 32 binary codes pulse signal, duration of the pulse signal itself wraps with it
The binary zero contained and the number of " 1 " are different and different, about between 45~63ms (millisecond).
For short-press bonded state, remote controler would generally issue single (aperiodic) pulse signal.
For long-pressing bonded state, remote controler would generally issue cyclic pulse signal, and the period is usually about 108ms,
Waveform diagram is referring to Fig. 3.Its principle is that after a key is pressed more than 36ms, oscillator activates chip, flip chip hair
One group of coded pulse signal is penetrated, this coded pulse signal is by an initial code (Shi Changwei 9ms), a result code (Shi Changwei
4.5ms), a length of (9ms~18ms) when least-significant byte address code (Shi Changwei 9ms~18ms), most-significant byte address code, 8 numeric data codes (when
A length of 9ms~18ms) and 8 data radix-minus-one complement (Shi Changwei 9ms~18ms) composition.When first group of coded pulse signal emits
Afterwards, chip sends one group of coded pulse information at interval of the time cycle of 108ms, but opens from second group of coded pulse signal
Begin, do not retransmit numeric data code (and its radix-minus-one complement) but sends and continue " 0 " or continue " 1 ".Infrared receiver end (such as set-top box, intelligence
TV) after receiving above-mentioned pulse signal, such pulse signal is identified as long keying, until remote controller key is lifted
Afterwards, chip does not retransmit any pulse signal.
The embodiment of the present invention can according to the processing capacity of terminal (such as set-top box, smart television) (such as: at processor
Each abilities such as reason speed, currently processed efficiency) determine prefixed time interval, for example, terminal stronger for processing capacity,
80ms can be set by prefixed time interval, to improve terminal to the response speed of remote controller key, particularly with length
For key, every 108ms from the prior art responds a user's operation, is increased to every 80ms and responds a user's operation,
When user consecutively presses a certain key 500ms, the processing time of 4 × (108-80) milliseconds is saved, to improve terminal
To the response speed and sensitivity of long keying；The terminal weaker for processing capacity, can set prefixed time interval to
200ms avoids terminal in this way, the embodiment of the present invention can also reduce the response and processing pressure of terminal to a certain extent
Insensitive phenomenon is responded to long keying.
Fig. 7 shows the flow diagram that a kind of set-top box provided in an embodiment of the present invention carries out pulse signal processing, such as
Shown in Fig. 7, which may include:
Step 701: the infrared receiving module of set-top box receives the pulse signal sent by remote controler.
Step 702: the arteries and veins that the recognition unit in the pulse signal processing unit of set-top box receives infrared receiving module
Data corresponding to signal are rushed to be saved in buffer area.
Step 703: the recognition unit of pulse signal processing unit judges corresponding to the current PRF signal in buffer area
Whether remote controler key assignments is carried in data, if so, thening follow the steps 704；Otherwise, step 706 is executed.
Step 704: the current key-press status of remote controler is identified as short-press key by the recognition unit of pulse signal processing unit
State.
Step 705: the remote controler key assignments in current PRF signal is transmitted to by the processing unit of pulse signal processing unit
The related process module of set-top box is handled.
After executing above-mentioned steps 705, terminate this process, that is to say, that the embodiment of the present invention is through the above steps
701~step 705 completes primary short recognition by pressing keys and processing operation.It should be understood that execute above-mentioned steps 705 it
Set-top box can still continue to execute step 701 afterwards.It should also be noted that, each long keying is with a short-press bonded state
Pulse signal is initial pulse signal and there are continuous several not carry the pulse signal of remote controler key assignments.As it can be seen that even if logical
It crosses above-mentioned steps 705 and identifies that the current key-press status of remote controler is short-press bonded state, it still can be in the follow-up process by the short-press
Initial pulse signal of the corresponding pulse signal of bonded state as a long-pressing bonded state.
Step 706: the current key-press status of remote controler is identified as long keying by the recognition unit of pulse signal processing unit
State, and before current PRF signal and to carry the pulse signal of remote controler key assignments as the starting of current long keying
Pulse signal.
After having executed above-mentioned steps 706, step 707 can be continued to execute, can also directly execute step 711.
Step 707: the recognition unit of pulse signal processing unit will be from current PRF signal to initial pulse signal between
Time difference, as current key duration.
Step 708: it is default that the recognition unit of pulse signal processing unit judges whether current key duration is greater than or equal to
Key duration, if so, thening follow the steps 709；Otherwise, step 710 is executed.
Step 709: the processing unit of pulse signal processing unit is according to prefixed time interval, the remote control keys that will do not carried
The related process module that the message of value is transmitted to set-top box is handled, so that related process module, which receives, does not carry remote controler
It is handled after the message of key assignments using current key as long keying.
Step 710: the processing unit of pulse signal processing unit ignores current PRF signal.
Specifically, the processing unit of pulse signal processing unit does not transmit any information in current PRF signal, but
Directly ignore the pulse signal.
When specific implementation, the embodiment of the present invention can accelerate the actual treatment speed of continuous key-press (long keying), but by
In user, there are many key-cases, slower particularly with acting according to the feel of remote controler and the difference of user's use habit
Slow the elderly or remote controler insensitive for certain keys, the key duration of user can be longer, tests through statistical sampling,
It may be between 36ms to 300ms when the actual key duration of user.In general, 36ms is exactly minimum activation remote processing core
The shortest time of piece, once the actual key duration of user be greater than 108ms after, will there is a phenomenon where even key, but in fact,
In this case, the original intention of user merely desires to click key (as short-press bonded state), but leads to terminal since key duration is longer
Carry out long keying response, it is most evil bad to affect user experience.The embodiment of the present invention is further to long keying state recognition process
It is optimized, according to programmable button duration, which can be accustomed to duration adaptivity according to user key-press
Adjustment is adjusted according to experiment value, and the long keying received is optimized processing, it may be assumed that (actual key duration-pulse letter
Number period)/prefixed time interval, and the result round numbers operation to obtaining.For example, the pulse signal of set-top box handles dress
The long keying of a length of 300ms is handled according to following algorithm when the recognition unit set is for one: a length of when with actual key
For 300ms, pulse signal cycle 108ms, prefixed time interval are 80ms, key assignments (is pressed) for the press, due to
At this moment (300-108)/80=3 needs to lose subsequent 3 successive values of the value, since the 4th key assignments by 80ms it is default when
Between be spaced key assignments processing.In this way, the embodiment of the present invention is able to solve the company's key problem clicked under response mostly, and further solve
The insensitive problem of continuous key-press of having determined.
Step 711: the processing unit of pulse signal processing unit is according to prefixed time interval, the remote control keys that will do not carried
The related process module that the message of value is transmitted to set-top box is handled, so that related process module, which receives, does not carry remote controler
It is handled after the message of key assignments using current key as long keying.
