According to implementation method of the present invention, described receiving system is handled described reference number, and the instruction of execution and the corresponding remote controller signal of described reference number.
According to implementation method of the present invention, the identification code of described remote controller signal is its systematic code.
According to implementation method of the present invention, described reference number is to prestore to be located at a kind of remote controller signal coding in the described receiving system.
The present invention also provides a kind of receiving system, comprise the remote controller signal receiver module, it is characterized in that, also comprise signal identification module and signal conversion module, described signal identification module is deposited and is provided with at least two kinds of remote controller signal encoded radios, described remote controller signal receiver module transfers to described signal identification module with the remote controller signal that receives, described signal identification module identifies its coding according to the identification code of the remote controller signal that receives, and converts described coding transmission to described signal conversion module to a reference number.
According to receiving system of the present invention, described receiving system also comprises signal processing module, handles described reference number by described signal processing module, and the instruction of execution and the corresponding remote controller signal of described reference number.
According to receiving system of the present invention, the identification code of described remote controller signal is its systematic code.
According to receiving system of the present invention, described reference number is to prestore to be located at a kind of remote controller signal encoded radio in the described receiving system.
Compared with prior art, advantage of the present invention and good effect are: the implementation method of the receiving system by multiple remote controller signal compatible of the present invention, can realize that receiving system receives two kinds and two or more remote controller signals, and different remote controller signals coding all converts unified reference number to and handles, do not influence processing and operating part in the receiving system, strengthen the versatility of receiving system, saved production cost.
Description of drawings

Fig. 2 is the theory diagram with the receiving system of the corresponding multiple remote controller signal compatible of Fig. 1.
Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
All be provided with emitter chip in the remote controller, send infrared signal, receive for receiving system by described emitter chip.Existing remote controller is a lot of with the emitter chip kind, can be divided into two big classes according to coded format, one class is to realize the pulse-width modulation class chip of signal modulation by pulse duration, and another kind of is the pulse-time modulation class chip of realizing the signal modulation by the time interval between the pulse train.No matter adopt which class chip, the coding of the remote controller signal of reflector emission all comprises systematic code and the identification push button signalling function operations sign indicating number of discerning remote controller.The signal encoding of different remote controller emissions has different systematic codes, with the pairing different electric equipment of difference remote controller, prevents the mutual interference of different machine remote controller signal coding phase.
See also the flow chart of an embodiment of implementation method of the present invention shown in Figure 1.Described embodiment is in the example with the set-top box, the set-top box receiving system prestores and is provided with the remote signal coding that at least two kinds of set-top box remote controllers send, and with wherein a kind of remote signal coding acquiescence coding as receiving system, also be the reference number of system, the systematic code of this coding is as the default system sign indicating number of receiving system.Described embodiment realizes that the flow process of multiple remote controller signal compatible is as follows:
S101: flow process begins.
S102: receiving system receives the remote signal that remote controller sends.
S103: judge whether the systematic code in the received remote signal coding is the default system sign indicating number that receiving system sets.If the default system sign indicating number that system sets, the remote signal that expression receives is to be sent by the remote controller that receiving system is given tacit consent to, and goes to step S106; If the systematic code in the received signal is not the systematic code of receiving system acquiescence, then execution in step S104.
S104: judge whether the systematic code in the received remote signal coding is the other system sign indicating number that receiving system is supported, judge promptly whether the remote controller signal coding that receives is a kind of coding that is preset in the receiving system.If the other system sign indicating number that system supports then goes to step S105; If not the other system sign indicating number that system supports represents that then the remote controller signal that receives is not the signal that set-top box remote controller sends, then go to step S102, continue to receive remote signal.
S105: with the remote signal code conversion that receives is the coding of receiving system acquiescence, and promptly all codings all are converted to unified coding.In receiving system, all corresponding conversion table that is converted to the acquiescence coding of the coding that each receiving system is supported is all to convert various codings to unified acquiescence coding.
S106: receiving system is handled described acquiescence coding, and sends it in the application system, carries out and the corresponding remote signal instruction action of encoding of described acquiescence.
S107: flow process finishes.
The reference number of the foregoing description is to have selected for use to deposit wherein a kind of remote controller signal coding of establishing in the receiving system, can certainly redefine a cover coding as reference number, and be the reference number that redefines the various remote controller signal code conversion that are located in the receiving system of depositing.
Fig. 2 is the theory diagram with the receiving system of the corresponding multiple remote controller signal compatible of Fig. 1.Described receiving system comprises the remote controller signal receiver module, and described signal receiving module receives the infrared signal that remote controller sends, and with the coding transmission of received signal to signal receiving module.Described signal receiving module is deposited and is provided with at least two kinds of remote controller signal codings, behind the coding that receives the signal receiving module transmission, according to the kind of the systematic code recognition coding of encoding.If the coding that receives is the acquiescence coding of receiving system, then directly code signal is transferred to signal processing module.Acquiescence coding if not receiving system then transfers to signal conversion module with code signal.Described signal conversion module converts the code signal that receives to the acquiescence coding, and transfers to signal processing module, and code signal is handled, and finally carries out the function of remote controller signal.
The present invention has strengthened the versatility of receiving system by being unified reference number with the multiple remote control code conversion, in the area of having only remote controller difference, does not influence the sale and the use of product.
Certainly; the above only is a kind of preferred implementation of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
