Embodiment
As depicted in figs. 1 and 2, in the present invention, the method for changeing copy television set data with remote controller is to realize by the microprocessor control circuit in the television set and remote control circuitry are improved, and needs the support of software.Here we are called copy television set 2 having the television set that changes the copies data function, and are called copy remote controller 1 having the remote controller that changes data in the copy television set.
Similar to general television set, include devices such as microprocessor 20, memory 21, receiver of remote-control sytem 25, signal processing apparatus 22, tuner 23 and picture tube 24 in the copy television set 2.But the difference part of itself and general television set is also to have installed a remote-controlled transmitter 26 (infrared signal transmitter), is used for to copy remote controller 1 wireless transmission data.
Compare with the operation principle of general remote controller, include keyboard 12, microprocessor 10, remote-controlled transmitter 13 equally in the copy remote controller 1.But it is also to be provided with a receiver of remote-control sytem 14 (infrared signal receiver) and memory 15 with general remote controller difference part.Receiver of remote-control sytem 14 is used for receiving the data that copy television set 2 is sent, and memory 15 is used for these from copying the storage that television set 2 sends over.And in keyboard 12, be provided with " data read request " key and " request of a data copy " key (not shown).Wherein, the data read request key is used to start the request of sending reading of data to copy television set 2, and data copy request key is used to start to copy television set 2 and sends the request that writes data.Copy television set 2 is read-write memory with the memory 21,15 that copies in the remote controller 1.
In the time need changeing copy to the data of copy television set 2, with copy remote controller 1 receiver of remote-control sytem 25, click the data read request key on the copy remote controller 1 facing to copy television set 2, copy remote controller 1 will begin and 2 collaborative works of copy television set.The data of memory will send copy remote controller 1 singly by the address of memory in the copy television set 2, and memory copies in copy remote controller 1.
Face toward another with copy remote controller 1 then and need the receiver of remote-control sytem 25 of the copy television set 2 of copies data, click " data copy request key " on the copy remote controller 1, copy remote controller 1 will begin and 2 collaborative works of copy television set.In the copy remote controller 1 data of memory 15 with the address of interdependent reservoir 15 singly in copy television set 2 memory 21 copy.So just be equivalent to the data that editted (programme content),, copy to another copy television set 2 from copy television set 2 commentaries on classics by copy remote controller 1.We call the previous copy television set 2 of sense data " copy machine tool 2 ", and a back copy television set 2 that writes data is called " copy targeting machine ".
Specify the process of utilizing copy remote controller 1 to carry out data read and change copy below in conjunction with Fig. 3～Fig. 6.
At first introduce data read process, the data read of indication here is meant and utilizes copy remote controller 1 to read the data in the copy machine tool 2 and it is stored in process in the memory 15 of copy remote controller 1.Particular flow sheet as shown in Figure 3 and Figure 4.
When need copy to the data of television set, the television set conduct " copy machine tool 2 " that at first will look for various data and programme content to debug, edit.Click the data read request key on the copy remote controller 1, copy remote controller 1 sends read data request signal (step S305) to copy machine tool 2, set up the start address pointer simultaneously, the initial value of address pointer points to the lowest element address (start address) (step S310) of memory 21 to be copied, then the address information of preparing copy is added in this read data request signal (step S315), microprocessor 10 becomes infrared signal (step S320) with this read data request signal with the address information signal modulating-coding, send this infrared signal to copy machine tool 2 (step S325) by the remote-controlled transmitter 13 that copies remote controller 1 then.
The data of copy machine tool 2 are copied to the process that copies in the remote controller 1, are to copy respectively singly by the address that copies memory 15 in the remote controller 1, and data of every copy all will be carried out verification, so be not easy to make mistakes.In data read and copy procedure, the address pointer among Fig. 3 and Fig. 4 has played key effect here.In fact so-called address pointer is exactly a counter, and address pointer is pointed to the purpose of storage address to be copied, is in order to make data processing simple, directly by shining upon, need not to carry out the numerical computations of address.
For example, to memory 15 copies data of copy in the remote controller 1 is that lowest address from this memory 15 begins, if memory 15 lowest address are No. 01 (or other number number also has no relations), when copy remote controller 1 for the first time when copy machine tool 2 sends the read data request signal, also to send to copy machine tool 2 to No. 01 this data message of address.Also will set up address pointer in copy machine tool 2, the lowest order of address pointer points to the lowest order of the address of memory 21 equally.If the address pointer lowest address also is No. 01, two numbers equate to be a kind of coincidence fully, they not necessarily need to equate in fact, only need remember the number of address pointer in the time of copy, can find actual address number in memory 15 and 21 equally by corresponding relation, that is: what are all has no relations the absolute address` of memory.
After copy machine tool 2 is received the read data request signal for the first time, its microprocessor 20 can be set up a transient data management district, and it is corresponding with copy remote controller 1, set up an initial address pointer, this address pointer points to the address of the data storage 21 that continues, the start address pointer that promptly copies in the remote controller 1 is identical with the initial address pointer state of copy in the machine tool 2 substantially, according to the numerical value of address pointer the data of 21 corresponding address in copy machine tool 2 memories are read then, temporarily store in the transient data management district, thereafter the data in the transient data management district (address code and numeric data code) are carried out modulating-coding, and export to the infrared signal transtation mission circuit.
Binary signal can not directly carry out the signal transmission generally speaking, just can carry out infrared signal after must modulating sends, simple modulation mode is pulse width modulation, represent binary coding with the length pulse train, such as: represent " 1 " with long bursts, represent " 0 " with burst.Meanwhile, microprocessor 20 also will be exported shows signal and give the video amplifier circuit (not shown), allows picture tube 22 information of carrying out show that the expression data copy in progress or copy successfully and wait.
When copying remote controller 1 after copy machine tool 2 sends read data request signals and address information signal, it can be waited for and receive the data-signal (step S330) that copy machine tool 2 is beamed back, if after the past scheduled time, copy remote controller 1 is not received the data-signal that copy machine tool 2 is beamed back yet, then copy remote controller 1 and judge at first whether the address pointer in the readout data signal that it sent overflows (step S332), as overflow then EP (end of program), otherwise turn to step S315, attempt sending read data request signal and address information signal to copy machine tool 2 once more, repeatedly still can not receive if repeat, represent that then intercommunication is undesired, copy work leaves it at that; If can receive the data-signal that copy machine tool 2 is beamed back, the expression intercommunication is normal, and copy work is proceeded.
Copy remote controller 1 at first is to carry out demodulation (step S335) to received signal after receiving the data-signal beamed back of copy machine tool 2, and it is very simple that pulse signals is carried out demodulation, just is easy to isolate binary code with the method for counting.And the address deciphered (S340), and from the result, take out address code then and analyze, compare (S345) with data in the address pointer in the read data request that sends out.If the address code of beaming back is different with the address code that sent out originally, it is not right that the data of coming are beamed back in expression, can not use, and needs to retransmit.Process repeats repeatedly to attempt, and it is still not right to beam back the data of coming, and copy work leaves it at that, and in this process, still will judge the step (step S350) whether first address pointer in the readout data signal overflows, and this step S350 and step S332 are similar.If the address code of beaming back is the same with the address code that sent out originally, it is correct that the data of coming are beamed back in expression, can use, and copy work is proceeded.
After the address code empirical tests that copy remote controller 1 is received is correct, could from demodulation result, take out address code and numeric data code, these data are deciphered (step S355), and this address code correspondence position pointed is stored (step S360) in memory 15 then.After the storage of an address code finished, first address pointer added 1 (step S365) automatically.Program turns back to preceding step S315 again, sends the read data information signal that contains address information signal to copy machine tool 2 once more, and continues the course of work of front, till the data in copy machine tool 2 memories 21 all have been copied.After the data that copy last address to, initial address pointer in the copy machine tool 2 still will add 1 automatically, but the storage address of point backward does not exist, because microprocessor 20 each copies will check all whether the value of address pointer overflows later, if overflow, the carrying out that copy machine tool 2 will stop to copy work, the expression copy finishes.After copy machine tool 2 quit work, copy remote controller 1 will can not receive the recall signal of copy machine tool 2, and copy remote controller 1 repeats to send signal several times, and after can not receive 2 times letters of copy machine tool, also can autostop.
As shown in Figure 4, introduce the working condition of copy machine tool 2 more in detail, after copy machine tool 2 is received read data request signal (step S400) for the first time, at first this read data request signal is carried out demodulation (step S410), output shows signal (step S415), its microprocessor 20 can be set up a transient data management district (step S425), and it is corresponding with copy remote controller 1, also set up an initial address pointer (step S430), the continue address of data storage 21 of initial address pointed, first address pointer that promptly copies in the remote controller 1 is identical with the initial address pointer state of copy in the television set 2 substantially, according to the numerical value of address pointer the data in the corresponding address in copy television set 2 memories are read (step S455) then, temporarily store in the transient data management district, thereafter the data in the transient data management district (address code and numeric data code) are carried out modulating-coding (step S460), export to remote-controlled transmitter 26 (step S465) and utilize this remote-controlled transmitter 26 that its form with infrared signal is sent (step S470).In the process of the signal that receives this read data request, if surpass the regular hour, this program can withdraw from (step S405) automatically.
After copy television set 2 is received the read data request signal once more, signal is through separating the decoding of mediation address information, microprocessor 20 will and receive that address pointer compared (step S440) last time to the address code received, if comparing with the address code that received last time, the address code of receiving do not increase, the request signal that expression is received is repetition (old), then directly turn to step S455, microprocessor 20 will take out corresponding data by original address pointer, send to copy remote controller 1 once more by infrared signal behind information coding and modulating-coding.
If comparing with the address code of receiving last time (being address pointer), the address code of receiving increases, the request signal that expression is received is new, at this moment the initial address pointer can add 1 (step S445) automatically, then turn to step S455, microprocessor 20 will take out corresponding data by new address pointer this moment, send to copy remote controller 1 by infrared signal behind information coding and modulating-coding.
Between step S445 and step S455, also exist and judge the step (step S450) whether address pointer overflows, when the numerical value of address pointer exceeds the numerical value of storage address in the copy television set 2, MPU can make judgement automatically, stopping copy work carries out, copy remote controller 1 will can not receive the recall signal of copy television set 2 like this, and the work of expression copy finishes.
Point out in passing, in the process of data read, copy remote controller 1 is different with the infrared signal information that copy television set 2 sends mutually, copy remote controller 1 sends in the infrared signal information that copies television set 2 has only address information, and copy television set 2 sends to that existing address information also has data message in the infrared signal information of copy remote controller 1, grows up about one times so copy television set 2 sends the coding that the encoding ratio copy remote controller 1 of signals sends signal.Complete infrared signal coding should be made up of 4 parts such as synchronous head, address code, numeric data code, end code.
Introduce the process that data copy in conjunction with Fig. 5 and Fig. 6 more below, data copy described here is meant that copy remote controller 1 writes data the process of copy targeting television set.The principle of itself and data read is basic identical, and just television set and remote controller have been changed a role mutually.
As shown in Figure 5, copy remote controller 1 also is to copy respectively singly by the address that copies memory 15 in the remote controller 1 to the process of copy targeting machine 2 copies data, is provided with address pointer at copy remote controller 1.During the copy beginning, the lowest order of address pointer points to the lowest address in the memory 15, and promptly copy is the lowest order address from copy remote controller 1 memory 15.
At first press the data copy request key on the copy remote controller 1, copy remote controller 1 will send copy request signal (step S500) to copy targeting machine 2, set up first address pointer (step S505) simultaneously, the initial value of address pointer points to the lowest element address of shellfish memory 15, read the data of this address location then, (step S510), microprocessor 10 becomes infrared signal (step S515) with data with the address information signal modulating-coding, send this infrared signal to copy targeting machine 2 (step S520) by the remote-controlled transmitter 13 that copies remote controller 1 then.
Copy remote controller 1 is after copy television set 2 sends the copies data request signal, can wait for the recall signal (step S525) that receives the copy targeting machine, if can not receive the recall signal that has address information of copy targeting machine 2 in the given time, then microprocessor 10 judges whether first address pointer overflows (step S560), if overflow then EP (end of program), if do not overflow, then turn to step S510, copy remote controller 1 and can repeated multiple times send the infrared signal that has address and data message, just terminator execution after attempting repeatedly getting nowhere to the copy targeting machine.If receive the recall signal of copy targeting machine 2, then this signal is carried out demodulation, the row address of going forward side by side decoding (step S535, S540), whether the value of judging address information wherein correct (step S550), if to can repeated multiple times sending the infrared signal that has address and data message to copy targeting machine 2, just terminator is not carried out after repeatedly trial gets nowhere yet.If address information is right, then first address pointer adds 1 automatically, and program goes to step S510, carries out the data copy procedure of next address unit.
As shown in Figure 6, copy targeting machine 2 is received (step S600) behind the request signal, separate at first to received signal to be in harmonious proportion and decipher (step S610, S620), meanwhile, microprocessor 20 also will be exported shows signal and give signal processing apparatus 22, allow picture tube 24 information of carrying out show, expression data copy carries out.
When copy targeting machine 2 is received the copies data request signal for the first time, microprocessor 20 can be set up a transient data management district (step S630), and it is corresponding with copy remote controller 1, also set up an initial address pointer (step S635), address pointer points to the address of preparing copies data memory 21, be in harmonious proportion the data decipher out and be temporarily stored among the transient data management district (step S640) through separating, then address date is analyzed.Judge whether this address code increases (step S645).If receive that the value of address date of signal is identical with the value of address pointer, the signal that expression copy targeting machine 2 is received is 1 first time of copy remote controller or the last signal that sends, then go to step S660, microprocessor 20 will arrive the data conversion storage that is temporarily stored in data management area among the storage address of correspondence according to the numerical value of initial address pointer.If the value of address date of receiving signal is greater than the value of initial address pointer, the signal that expression copy television set 2 is received is the new signal that did not send before the copy remote controller 1, microprocessor 20 will be earlier adds 1 (step S650) to the value of initial address pointer, and then according to the numerical value of new address pointer the data conversion storage that is stored in data management area (step S660) among the corresponding storage address.
The data of a storage address of copy targeting machine 2 every copies, all will send back to copy remote controller 1 with ultrared form the address information coding that is copying and through remote-controlled transmitter 26 after copy finishes, promptly both sides will carry out verification (step S665, S670, S675) to address information.
Point out in passing, in the data copy procedure, copy remote controller 1 is different with the infrared signal information that copy targeting machine 2 sends mutually, copy remote controller 1 sends to that existing address information also has data message in the infrared signal information of copy targeting machine, and copy targeting machine 2 sends to and has only address information not have data message in the infrared signal information of copy remote controller 1, grows up about one times so copy remote controller 1 sends the coding that the encoding ratio copy targeting machine of signal sends signal.This content with front one joint " data read process " is just in time opposite.In addition, also be provided with an out-of-date wait handling procedure in the copy targeting machine 2,, do not receive that to square signal television set also can be shut down (step S605) when copying failure after wait as long for.
What need explanation a bit is: above-mentioned narration only is that a most preferred embodiment of the present invention is described, by essence of the present invention, can derive the embodiment of many changes, for example, when the space of data management area is enough big, also all data once can be transmitted, and need not to transmit singly by the element address of memory; In the present invention, the transmission of data is to realize by wireless mode, and present embodiment is that infrared ray transmits, but does not get rid of the wireless transmission of other modes, as blue bud, radio frequency transmission (RF) etc.
In the present invention, hardware there is following requirement:
A pin is preferably arranged is bidirectional interface to the microprocessor 20 of copy television set 2, promptly can input data signal also can outputting data signals, be used for infrared signal and receive and send.If there is not bidirectional interface, just need take two pins of microprocessor 20, import for one, be used to receive infrared signal; Export for one, be used to send infrared signal.If the resource of existing television set microprocessor 20 can not satisfy top requirement, also can be at the I of existing television set
2An infrared signal port is installed on the basis on the C bus.The data management of this interface also needs a microprocessor (not shown), is used for synchronous communication is changed into asynchronous communication, and has coding and decoding function and modulation function.
Owing to pass through I
2Data that can the direct read memory on the C bus, so independently realize that with a microprocessor data copy function of television set is simpler comparatively speaking, and almost do not take the resource of microprocessor 20 on the original machine at all, on existing television set, reequip the data copy function that just can realize television set a little.
The function of microprocessor is very simple in the copy remote controller 1, only needs several input/output ports to come to manage and provide a data input/output port to use as the infrared signal port to memory and gets final product.The capacity of memory 15 is more preferably greater than the capacity that copies memory 21 in the television set 2 in the copy remote controller 1, if the capacity of memory 15 is less than the capacity of memory in the copy television set 2 in the copy remote controller 1, program of file copy can not normally be carried out.
