For reaching above-mentioned purpose, on the one hand, the invention provides a kind of remote control mode, comprise the guidance code, user code and the key data sign indicating number that are arranged in order, after described key data sign indicating number, also comprise the growth data sign indicating number; Wherein, a key assignments in the described key data sign indicating number is set to send or receive the expansion sign indicating number identification code of described growth data sign indicating number.
Further, between described key data sign indicating number and growth data sign indicating number, also be provided with synchronous code.
On the other hand, the invention provides a kind of sending method of remote control mode, said method comprising the steps of:
At first judge whether to send the growth data sign indicating number, if, then send the expansion sign indicating number identification code that is provided with in the described key data sign indicating number, then, send guidance code, user code, key data sign indicating number and growth data sign indicating number successively; If not, then send guidance code, user code, key data sign indicating number successively.
Further, after sending described key data sign indicating number, send synchronous code.
Again on the one hand, the invention provides a kind of method of reseptance of remote control mode, said method comprising the steps of:
Receive remote control mode, detect guidance code, user code, key data sign indicating number successively;
Judge whether the described remote control mode that receives is to expand the sign indicating number identification code, if then detect described growth data sign indicating number, and export the data of described growth data sign indicating number; If not, then export the data of described key data sign indicating number.
Further, after detecting described key data sign indicating number, detect synchronous code.
Beneficial effect of the present invention is as follows:
The present invention increases a growth data sign indicating number in common remote control mode rearmost end, and when needs sent the growth data sign indicating number, a key assignments in the key data sign indicating number was set to a code value of making an appointment and serves as a mark.The transmission of growth data sign indicating number has increased the key assignments quantity of remote controller, also makes remote controller possess data transmission capabilities simultaneously, and, because only in needs, just increase the transmission of growth data sign indicating number and former remote control mode compatibility fully.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, does not limit the present invention.
After remote control mode of the present invention expands, as shown in Figure 2; Comprise guidance code A, the user code C and the key data sign indicating number K that are arranged in order, D is the growth data sign indicating number; When having synchronous code S, follow closely after S; When not having S in the coding, D follows closely after K.
Because the key assignments of K generally all has 256, during general remote control applications, some key assignments does not use.Therefore, certain key assignments that is not used of making an appointment is as expanding a sign indicating number identification code, and the present embodiment supposition is a hexadecimal numerical value: with 0xFF as expanding a sign indicating number identification code.Certainly, also can be the value of other arbitary convention.
The sending method of the remote control mode that present embodiment relates to as shown in Figure 3, may further comprise the steps:
Be ready for sending remote control mode, at first judge whether to send the growth data sign indicating number, increase number of keys if desired, perhaps send data, then send the growth data sign indicating number.That is: send the expansion sign indicating number identification code that is provided with in the described key data sign indicating number, then, send guidance code, user code, key data sign indicating number and growth data sign indicating number successively; If do not need to increase number of keys, perhaps do not need to send data, when promptly sending normal remote control mode, then send guidance code, user code, key data sign indicating number successively.
In the above-mentioned steps,, then after sending described key data sign indicating number, send synchronous code if there is synchronous code.
The method of reseptance of the remote control mode that present embodiment relates to as shown in Figure 4, may further comprise the steps:
Receive remote control mode, detect guidance code, user code, key data sign indicating number successively;
Judge whether the described key data sign indicating number that receives is an expansion sign indicating number identification code, if, then detect described growth data sign indicating number, and export the data of described growth data sign indicating number, so just increased number of keys, can send data; If not, then export the data of described key data sign indicating number, in this case,, perhaps send data, with existing remote control mode compatibility though can not increase number of keys.
In the above-mentioned steps,, then after detecting described key data sign indicating number, detect synchronous code if there is synchronous code.
