After S1: the first reader obtains the authority of sharing service device, to the request that the described sharing service device initiation page is shared.
In the embodiment of the present application, the system architecture that the described page is shared at least can comprise sharing service device, the first reader and the second reader.In this system architecture, described sharing service device can be used as the terminal of data, is used for connecting and coordinating described first reader and the second reader.Described first reader can be the initiator that the page shares request, that is, described first reader can be propose the page to share request and by a side of sharing service device granted rights, described second reader can be the recipient that the page is shared, described first reader and the second reader can be computers, can be panel computer, also can be smart mobile phone or other-end equipment, the application limit this.Can be communicated by the Internet between described first reader, the second reader and sharing service device, certainly, also can be communicated by local area network (LAN), the application does not limit equally to this.It should be noted that, in the actual system architecture of the embodiment of the present application, the quantity of described sharing service device and described first reader all can be 1, and the quantity of described second reader can be multiple.That is, at one time in section, the initiator sharing page request often can only have 1, and the recipient sharing the page can have multiple, this multiple recipient sharing the page all as the extension naturally of the second reader, can have identical function with the second reader.In addition, first reader described here and the second reader not representation page are shared and are had proper sequence, initiate the page when the second reader and share request and after being authorized by sharing service device and sharing authority, described second reader just can serve as the role of the first reader, carries out the page and shares; Now the first reader then can serve as the role of the second reader, receives the page and shares.That is, " first " and " second " is here only used to " current character " to show differentiation, does not have the restriction of any proper sequence.The embodiment of the present application only carries out for 1 the second reader the technical scheme setting forth the application, but it will be appreciated by those skilled in the art that, this does not also mean that the technical scheme of the application is only applicable on 1 the second reader.In addition, although the embodiment of the present application is using reader as proposing to share and receive the medium shared, when those skilled in the art should know, the technical scheme of the embodiment of the present application is equally applicable to the have page similar with reader and shares in more media of demand with person's handwriting.
Described sharing service device can distribute authority to the reader in system, the request that the reader only with authority just can be shared to the sharing service device initiation page.The request that described sharing service device can be shared at the network port monitoring page of agreement, when the request that described first reader is shared to the described sharing service device initiation page, described sharing service device just can respond to this request.
S2: the request that described sharing service device is shared in response to the described page, indicates described first reader that the background data of current page is sent to named cache address.
When described sharing service device listens to from the network port of agreement the request that the page shares, just can, in response to this request, indicate described first reader that the background data of current page is sent to named cache address.It should be noted that, the content of this page from certain one page of reading material, can be shared to other readers by first reader of the application.And based on the content of this page, this page can be scribbled by person's handwriting, the content of scribbling also can be synchronized to other readers in real time, thus meets the needs of remote teaching.Here the background data of current page just can be the text data of current page, and described text data often can be shared on other readers as a setting.Here the handwriting data of current page just can be on current page, utilize person's handwriting to carry out the content of scribbling, this content can real-time Transmission on other readers.Here named cache address can be the network address residing for sharing service device itself, the handwriting data of the background data of current page and described current page just can be sent to described sharing service device by so described first reader, carries out follow-up distribution by described sharing service device; Here named cache address can also be the network address residing for described first reader, the background data of current page just can be sent in the memory module of self by so described first reader, described memory module may be used for the background data depositing current page, so follow-up can through the coordination of described sharing service device, distributed the background data of current page directly to other readers by described first reader.In the embodiment of the present application, the background data of described current page can be graphic form, also can be video stream.If graphic form, so described first reader just needs to be sent to named cache address by after the image data packing of sharing; If video stream, so described first reader just needs video flowing to be shared to be sent to named cache address according to certain transmission frame per second.
Particularly, in the application one preferred embodiment, when when the page data shared is video flowing, step S2 can be realized by following two steps:
S21: the request that described sharing service device is shared in response to the described page, sends transfer of data frame per second and named cache address to described first reader.
When described sharing service device listens to the request that the described page shares, just in response to this request, transfer of data frame per second and named cache address can be sent to described first reader.Described transfer of data frame per second can carry out free change according to network state, if network state is better, bandwidth is comparatively large, and so described transfer of data frame per second can arrange higher, such as, can be 40 frames/second; On the contrary, when network state is bad, when spendable bandwidth is less, described transfer of data frame per second just can suitably arrange lower, such as, can be 20 frames/second.Transfer of data frame per second and named cache address can be sent to described first reader place as the configuration information of transfer of data by described sharing service device, and described first reader just can carry out transfer of data according to this configuration information.
S22: the background data of current page, according to described transfer of data frame per second, is sent to described named cache address by described first reader.
After described first reader receives described transfer of data frame per second and named cache address, just according to described transfer of data frame per second, the background data of current page can be sent to described named cache address.
In another preferred embodiment of the application, at described first reader according to described transfer of data frame per second, before the background data of current page is sent to described named cache address, described sharing service device can also specify the first data format to described first reader.Described first data format can representative data transmission coded system, it can be such as Shannon-Fano (Shannon-Fano) coding, Huffman (Huffman) coding etc., after the first data format specified by described sharing service device, the format conversion of the background data of current page can be become described first data format by described first reader, the meaning of such process is, if page data amount to be shared is larger, then can pass through the mode of format conversion (in other words code conversion), page data described to be shared is compressed, thus the efficiency of transfer of data can be improved.Correspondingly, the page data to be shared with described first data format according to described transfer of data frame per second, can be sent to described named cache address by described first reader.
Due to may some readers be there is in the system architecture that the page of the embodiment of the present application is shared, and multiple reader may be had in these readers all to need to carry out the page share simultaneously, and the same period should only allow 1 reader initiation page to share request, other the page is shared request and should be carried out after end shared by this reader again.Therefore, the application one preferred embodiment, before step S2, can also comprise:
S11: request queue is shared in the scanning of described sharing service device, confirms that request that the page that described first reader is initiated is shared shares the first place of request queue described in being positioned at.
What all pages shared that request all can be placed in sharing service device shares request queue, and according to the principle of first in first out, shares the request of request queue first place described in priority treatment is positioned at.So when the first reader initiation page shares request, described sharing service device needs first to confirm that request that the page that described first reader is initiated is shared shares the first place of request queue described in being positioned at, and the page so just can initiated described first reader be shared request and respond.
S3: described sharing service device sends data transfer request to the second reader.
After the background data of described current page is sent to named cache address by described first reader, the recipient that described sharing service device just can be shared to the page sends data transfer request.After the recipient shared when the page agrees to this request, just can receive the background data of current page.
S4: described second reader, in response to described data transfer request, receives the described background data that described named cache address place sends.
The recipient that described second reader can be shared as the page, when the data transfer request that described second reader agreement sharing service device is sent, just in response to this request, can receive the described background data that described named cache address place sends.Particularly, if the network communication address of described named cache address residing for described sharing service device, so the second reader just can obtain described background data from sharing service device; If the network communication address of described named cache address residing for described first reader, so the second reader just can obtain described background data from the first reader.
Particularly, in the application one preferred embodiment, step S4 can be realized by following three steps:
