[embodiment]
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1, remote user interface service application system of the present invention is comprised of server end and client.Server end is normally served as by the powerful equipment of data-handling capacity, such as PC, server, media server etc.The main work of server end is to carry out complex calculations, storage data, and the connection data storehouse meets user's display interface that client is used with extraneous network or mutual generation of application program, processes the feedback information of client etc.Client is normally limited by data-handling capacity, the equipment that system resource relatively lacks forms, such as PMP (Portable Media Player, portable media player), Web TV, PDA (Personal Digit Assistant, personal digital assistant), mobile phone etc.Client is responsible for receiving and is transmitted user profile, and namely the information of reception server end and be shown to the user and watch receives user's input message and information is sent to server end.
Realize the application of remote subscriber interface, need to carry out corresponding perfect in shape and function to server end and client, wherein the service development of server end need to be realized three large functions: the information feedback of the user interface that internal data is processed, generation is suitable for the client demonstration, reception client is also processed; The function that the service development of client need to be realized mainly contains two: show user interface and obtain user input data and send server end to.
The internal data of server end is processed the data processing work that main execution needed client executing originally, now can finish fast data processing task by server powerful data-handling capacity and abundant system resource.Therefore the work of server end internal data processing is different and different according to the exploitation service.For example, exploitation client terminal web page function of browse, the data processing work of server end mainly is downloading web pages from the Internet, and passes through the web browser analyzing web page of server, stored cookie information, the Flash animation in the operation webpage etc.; If the service that the realization of exploitation client is sent and received e-mail, the data processing work of server end mainly is to realize POP3 and smtp protocol so, receive mail from the Internet, mail is sent to the Internet, the mail that the mail that the storage user receives and user write.Therefore, the exploitation of the internal data processing capacity of server end mainly is to realize that by network the client data processing capacity shifts, and realizes the optimization of data processing resources configuration between server end and client.
The user interface that generation is suitable for the client demonstration is will be shown to client user's information as content take server end, take the display screen of client as generating target, the parameters such as positioning accuracy according to the screen resolution of client, supported number of colours, input system (such as touch-screen) generate user interface, and the image of generation can be the JPG form.The display screen parameter that is equipped with because of the client of different embedded systems is different, realizes that remote subscriber interface shows that need to generate according to the parameter of display screen its interface that can correctly show provides the user.Although the embedded system of client is of all kinds, their screen resolutions have more unified specification.Such as Web TV, if when realizing the demonstration of high definition, its resolution is 1920*1080, if single-definition be 1280*720; The PDA of main flow and high-end mobile phone, its screen resolution is 240*320, the mobile phone screen of standard then is 176=*220.So when exploitation remote user interface service device end is served Presentation Function, only need to adapt to according to the resolution exploitation of these standards the demonstration of client.
When in generating user interface, can supply the functions such as client user's selection, click, select and click according to the difference at client input equipment precision interval.In this function of exploitation, can be according to the disposal ability of client and application scenario different, make different user interfaces and generate frequency.For the relatively strong client of data-handling capacity, when carrying out service call, generate frequency with higher user interface and generate user interface, demonstration information that so just can be more real-time is checked to the user; If the weak client of data-handling capacity, can be guaranteeing that not affecting the reduction interface, basis that the user uses and information is fed back generates frequency, to adapt to the data-handling capacity of this client.
Receive feedback information and the processing of client, realize that the user is with the interactive function of application program.If some application is one-side, do not exist with the user interactions needs, this part function of server can not developed, and for example checks the service of stock-market change.But most the application needs the mutual of user and application program, for example at the client browsing page, the user just can click literal and the picture that contains hyperlink according to the content of webpage, jump to the own interested page, if server end receives the information spinner of client the coordinate of mouse click and/or user's keyboard input character are arranged.Server end just can be converted into real application program input data after receiving these information, carries out data and processes.
Adopt remote subscriber interface to finish a target is exactly to simplify the system complexity of client as far as possible, so the demonstration user interface of client service exploitation implements relative simple with two functions obtaining user input data and send server end to.
The user interface that client shows be server end generate be sent to the data of client with picture or picture format, therefore, the interface display of client is in fact to Show Picture or image.This picture or image are that server end is that the client looks the display interface that body is made surely up and down, and the data that client need not this picture or image are added are processed.The form that client shows in remote interface service comprises JPG picture, GIF picture, TIFF picture, BMP picture or forms the MPEG2 image that generates etc. with code stream.
The function of obtaining user input data and being transferred to server end mainly is to read the input equipment information of client, is sent to server end.The client input equipment mainly contains mouse data and keyboard data.Mouse data is to receive and be transferred to server end with the form of coordinate, and keyboard data then is the ASCII character that receives user key-press, sends to server end with the form of ASCII character.Be connected by setting agreement between the server end of remote subscriber interface application system and the client, the mode of its connection depends on server end and the common agreement of supporting of client, in embodiments of the present invention, be connected by the IGRS agreement between server end and the client and realize, see also Fig. 2, server end is registered the service of supporting remote subscriber interface by the IGRS protocol stack, and the basic parameter of this service notice IGRS protocol stack.To supporting the service of remote subscriber interface, declaration can be carried out for client the specific parameter of several remote subscriber interfaces of service call simultaneously, such as user interface updating frequency value, and the client screen resolution of support.Be connected between server end and the client except realizing by the IGRS agreement, can also utilize the DLNA agreement of being initiated by 17 consumer electronics industry giants such as Intel, Philip, IBM, Hewlett-Packard, Microsoft, or take Japanese manufacturer as main ECHONET agreement.
See also Fig. 3, can be according to the situation of oneself when client is carried out service call, the remote subscriber interface special parameter of describing according to the service describing message of server end, and the corresponding with service of the parameter call remote subscriber interface that can receive according to this equipment.Can be with higher user interface updating frequency value such as a Web TV, with the stock market's change service of browsing of the resolution invoking server end of single-definition 1280*720.And a MP4 player can be the browsing page service of the parameter call server end of 640*480 with lower user interface updating frequency value and resolution.
Receive the service invocation request of client and confirm that book server satisfies when the service invocation request of client is provided that when server server is just accepted this remote user interface service call request of client call.
After server is accepted the service call of client, just carry out the internal data work for the treatment of, concrete internal data is processed the difference difference because of service.Using relevant with remote subscriber interface is the function of new user interface more after data are finished dealing with.More new user interface mainly contains two kinds of situations: the one, and when arriving, the request of user interface next update needs more new user interface; The 2nd, new user interface more when the service of client call has real-time update to need.The first situation is conventional renewal operation, and the time of renewal is that designated user interface update frequency value is determined when supporting remote user interface service by client call.Arrive when the time one, server end just generates up-to-date user interface, and this interface is sent to client with the form of JPG image, is shown to the user.The second is the renewal operation of processing timely event.The for example demonstration of the error message of some service call, some pop-up window, some instant result need to show etc.Also do not arrive when the user interface next update time like this, but when having event to need more new user interface, server end also can generate the New Consumers interface, send client to the form of JPG image.
When if the service that utilizes remote subscriber interface to call need to be stored data, server end just is saved on the server according to the data that the user profile such as ClientID (client identity), UserID (user identity) of client call service are used this user and this application program.
Utilize the remote subscriber interface of IGRS protocol development to change relatively slowly application so that embedded device is realized user interface, as utilize remote subscriber interface to realize the browsing page of embedded device, just need to be at the operating system the inside exploitation web browser of embedded device, reduce to a great extent the complexity of embedded system development, reduced the expense of client to hardware resource; Utilize remote subscriber interface to realize the mail transmission/reception function of embedded system, then do not need a large amount of email storage in embedded system, to have saved the storage resources of system's preciousness; In embedded system, utilize remote subscriber interface to check the fluctuation situation of stock market, trade security, can directly utilize the existing stock market of computer service account, save a stock market service account user's the expense of newly opening.
Realized the client and server end that remote subscriber interface is used, its complexity of developing new client functionality reduces greatly.Support by the remote subscriber interface technology, we can be directly in the new service of server end exploitation, the new service of increase only need to increase new service call in client to client and just can realize, therefore, has realized that there is good extensibility in the system of remote subscriber interface.
