Preferred embodiment of the invention

In order to make the objects, the technical solutions and the advantages of the present invention more clearly, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments of the present application may be arbitrarily combined with each other.

The technical solution of the present invention realizes dynamic expansion. Existing application sites are generally confirmed in advance, which applications need to be shared, and the content and protocols shared by the application have been confirmed, and implementation is only required to be developed for these established specifications. For example, it is possible to develop an application for the catering industry or to develop an application for the transportation industry, but it is currently not possible to share applications with applications developed for the catering industry and applications developed for the transportation industry. The present invention is to solve such a technical problem. For this reason, it is required that the initial specification content is smaller (that is, sharing the initial desktop and the communication metadata format), and on this basis, what kind of application is shared, and what kind of data is shared, What process to establish a share can be negotiated in the metadata interaction.

In essence, there are three foundations for implementing dynamic expansion: the parsing of input actions, the division and representation of unit functions for shared content, and the metadata format for establishing interactions. The server provides a shared service, and the client requests a shared service. Taking the movie playing service as an example, the unit function of the movie playing can be divided into three functions of media data acquisition, media decoding, and media content display, and the server informs the client in a certain manner. A movie service that supports two functions of media data acquisition and media decoding. The client requests the movie service by inputting actions. The typical way is that the server displays its own movie service on the desktop and the pixels of its own desktop. The size and the desktop screen inform the client that the client inputs an action by means of a mouse click, and the server parses the input action of the client, and judges The object that is broken by the client is the movie service icon. The server manages the movie service icon in the form of a placeholder icon. The so-called placeholder icon refers to the attribute description of the application in addition to having a visual icon, and includes support for media data acquisition for the movie service application. Media decoding function, and the output format of the media. The server then sends the placeholder icon information to the client. The client provides feedback according to what functions the server needs. Then the server starts data sharing with the client according to the negotiation result. The so-called initial desktop includes environment information needed for subsequent application sharing, such as the length and width of the desktop and the number of pixels, the format and organization of the input data, the desktop image of the server, and the placeholder icon of the shared application provided by the server.

The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

The present embodiment is applied between a server and a client that interact using a near field communication method, and the near field communication includes, but is not limited to, Near Field Communication (NFC). The server has at least the capability of providing data services, and the server can also have an application function of data processing and performing view representation; the client has at least a display device, can establish communication with the server through the near field communication network, and can select the pair according to the situation. The data or application provided by the server is shared.

The following two cases of data sharing and application sharing are separately explained.

The method of data sharing, as shown in Figure 1, includes:

Step 101: After establishing a near field communication with the server, the client sends a request for obtaining the desktop configuration information to the server. After receiving the request, the server returns an initial desktop to the client, where the server supports the server. The identification information of each data file may further carry description information of each data file; wherein the identifier information is used to uniquely identify the corresponding data file;

Step 102: The client displays the identification information of each data file supported by the server to the user (if the description information is also displayed together), and initiates a shared data request to the server when determining that the user selects a data file for data sharing. , carrying the identification information of the data file selected by the user;

Step 103: The server searches for the corresponding data file according to the identifier information carried in the received shared data request, and then sends the data file to the client.

Step 104: After receiving the data file, the client may query the user for which application to process. The file, and launching a local application selected by the user, the data file is processed by the application. If the data file is composed of a continuous data stream (such as a multimedia file), after the client starts the application, the client sends a shared data request to the server again, and the server processes the request and provides a new data file. Until the user closes the local app.

In the specific implementation, after receiving the data file, the client can also automatically select an appropriate application according to the type of the file, and then start the application to process the data file.

Assume that both the server and the client have display devices, and the content displayed by the two is also consistent, that is, all display content on the server desktop can be displayed on the client. Taking a shared movie playing application as an example, the server device has a built-in movie player and can obtain movie media data, and the client does not support movie playing or movie media data, and can be shared by near field communication by using the above method. The server's movie playback app, watching movies.

The application sharing method, as shown in Figure 2, includes:

Step 201: After establishing a near field communication with the server, the client sends a request for obtaining the desktop configuration information to the server. After receiving the request, the server returns an initial desktop to the client, where the server supports the server. The identification information of each application may further carry the description information of each application; where the identifier information is used to uniquely identify the corresponding application;

Step 202: The client displays the identification information of each application supported by the server to the user (if the description information is also displayed together), and initiates a sharing application request to the server when determining that the user selects an application for application sharing. Carrying identification information of the application selected by the user;

Step 203: The server starts the corresponding application according to the identifier information carried in the received shared application request, and returns display information of the application.

Step 204: After receiving the display screen information of the application, the client finishes displaying on the display device. The user inputs the required information through an input device supported by the client, such as a keyboard, a mouse, or a touch panel. The client records the information input by the user, and converts the information into a format recognizable by the server, and then sends the information to the server. Wherein, if the information input by the user is related to the location on the display device, the client also needs to convert the coordinates of the location on the device to the coordinates of the server and then send the coordinates to the server;

Step 205, the server parses the information input by the user, and responds, if the interface is updated Displaying, sending new application screen information to the client;

After that, step 204 and step 205 are repeatedly executed, until after receiving the request sent by the client to close the application, the server responds and finally closes the execution of the corresponding application.

In the above description of the method of data sharing and application sharing, three key technologies, such as data file transmission, response to client input information, and server application screen information release, are involved. The transmission of the data file and the issuance of the application screen information can be directly realized by transmitting a communication packet containing the information tag and the information body. The response to the input information of the client involves the coordinate conversion of the input action, which is described in detail below.

The application screen information published by the server (that is, the initial desktop mentioned above) is composed of meta information and picture picture data, and the meta information includes at least coordinate information and geometric size information of the outer contour of the application picture. When the client displays the interface of the application or the initial desktop according to the picture picture data, the unified reference coordinates must be used uniformly.

The server needs to share the input simulation program with the client. The function of the input simulation program is to insert any original input actions into the server, such as mouse click, letter input, etc., and then share with the client. The appropriate input processing distribution mechanism translates into actual input actions to the initial desktop and/or each application. The input simulation program refers to inserting the input queue of the other party in the form of an input stack (drive layer concept) used by the other party in order to parse the input action and content of the client, that is, simulating the input action of the other party, such as mouse click or keyboard input.

When the client confirms that an input action is generated on the device, if it is a coordinate-related input, such as a mouse click on a certain position, it is necessary to synthesize the input action to perform coordinate conversion on the local screen coordinates and the reference coordinates, and calculate the The corresponding coordinates of the server. After the input action preprocessed by the device is sent to the server, the server inputs the virtual cost input through the local input simulation program, and then responds accordingly.

The communication messages between the client and the server are divided into four types: obtaining desktop configuration information, requesting shared data, synchronizing input actions, and refreshing display data. The communication text is composed of two parts: the header information and the data body. The header information includes a type field (8 bits) and a data body total length field (32 bits). The type field is used to indicate the type of the message, and the data body is total. The length field indicates the length of the data body packet contained in this packet. The data body has a corresponding format according to different packet types. Assume that the display device parameter of the server is 128 100 16, that is, the width is 100 pixels, the height is 128 pixels, and the display depth is 16 bits.

For the present embodiment, only three types of packets are used, and the formats are respectively defined as follows: Request packets for obtaining desktop configuration information: Type field value is 0x00, no data body message; Refresh message display data: Type The field value is 0x01, and the data body contains the upper left coordinate (16 bits), the width (8 bits), the height (8 bits), and the display data of the display area. The message of the synchronous input action: The type field value is 0x02. The data body contains the input type (occupies 8 bits) and the input information. Input types include character input ( 0x00 ), left mouse click ( 0x01 ), and right mouse click (0x02 ). The input information field of the character input contains an input Unicode character, which occupies 32 bits; the left mouse click and the right mouse click contain a coordinate field, occupying 16 bits; the application sharing process is further explained by an application example, such as As shown in Figure 3, the following steps are included:

Step 301: After the client connects to the server through the near field communication, the client sends a request message (0x0000000000) for obtaining the desktop configuration information to the server.

Step 302: The server obtains its current desktop display data (occupied, sends a refresh display data message to the client (0χ010003200000006480χχχχ), where xxxx represents desktop display data;

Step 303: The client receives the refresh display data packet, starts from the reference coordinate, starts drawing the initial desktop, and records the related data.

Step 304: The user selects an application for movie viewing by clicking, and after the client obtains the click operation, it determines that the operation is within the initial desktop range, and sends a synchronous input action to the server according to the reference coordinate (0x02000000300). Lxxxx ) , xxxx represents the corresponding click coordinates after coordinate conversion;

Step 305: The server forwards the received mouse click information to the input simulation program, and after processing, directly adds a corresponding mouse click event to the hardware input queue. In the application scenario, the server display program automatically completes the event processing, completes the event distribution, and the display program locates the click event for starting the movie play, completes the start of the movie player, and starts the movie play; Step 306, the server according to the movie The need to play the application, send the refresh display number to the client According to the message, the client completes the display update, loops back and forth, and completes the sharing function of the movie application.

The implementation of the input simulation program is adapted to the implementation method of the application sharing, and thus the different implementations do not hinder the scope of protection of the present invention. The difference between the display mode, the rotation, the transparency and the like of the client and the server does not constitute a limitation of the present invention. The present invention only requires that the client input action can be converted into a server input action.
