Along with the appearance at intelligent television terminal, abundant application can download and move on TV.But from the viewpoint of measures of user experience, the traditional remote controller function can not satisfy the needs of controlling.Under the situation that does not increase professional interactive device; How to make full use of intelligent handheld device at one's side and obtain better experience; Become a research emphasis; So be the center with the TV to around comprise the intelligent handheld device of touch-screen, gravity sensor, gyroscope, microphone, the first-class function of shooting peripheral hardware integrate; Extend TV functions, the idea of lifting means experience is used and is given birth to, and promptly is that multiplexing (being called the virtual peripheral technology) carried out to the existing peripheral functionality of other peripheral smart machine in the center with the TV; Yet also there is not a kind of effective method at present based on intelligent television terminal and handheld device realization virtual peripheral.
Summary of the invention
Technical problem to be solved by this invention is: propose a kind of method based on intelligent television terminal and handheld device realization virtual peripheral, the peripheral hardware that solves present intelligent television terminal can not satisfy the problem of controlling needs.
The present invention solves the problems of the technologies described above the scheme that is adopted: based on the method for intelligent television terminal and handheld device realization virtual peripheral; Said intelligent television is provided with the virtual peripheral oracle listener in the terminal; Be provided with the virtual peripheral client-side program in the said handheld device, this method may further comprise the steps:
A. intelligent television starting terminal virtual peripheral oracle listener is monitored the state of virtual peripheral;
B. handheld device starts the virtual peripheral client-side program, the intelligent television terminal in the search network environment;
C. on handheld device according to the result of search, selections needs the intelligent television terminal of connection;
D. operable concrete service is inquired about to handheld device in the intelligent television terminal;
E. the handheld device COS that can provide to the intelligent television endpoint registration;
F. handheld device is caught the virtual peripheral incident, and the virtual peripheral incident is sent to the intelligent television terminal according to specified format;
G. the intelligent television terminal receives the virtual peripheral incident, and is converted into discernible system standard incident, writes the respective drive file;
H. after accomplished event handling at the intelligent television terminal, disconnection was connected with handheld device.
Further, before step a, also comprise step:
A0. select the ethernet communication port numbers, the data transmission format between definition intelligent television terminal and the handheld device.
Concrete, adopt XML definition of data transformat, be divided into device description file, service description file, service description file, event description file.
Further, the virtual peripheral oracle listener in the said intelligent television terminal moves with the mode of Android Service, the port of appointment is carried out event-monitoring, through other component communication at IBinder interface and intelligent television terminal.
Further; Among the step h, said intelligent television terminal is broken off and with the handheld device ways of connecting is: notify disconnection to be connected or directly disconnection connection thereby the virtual peripheral oracle listener at intelligent television terminal sends disconnection with the virtual peripheral client-side program of handheld device.
The invention has the beneficial effects as follows: the function of handheld device is carried out multiplexing, thereby realize virtual peripheral, satisfy the intelligent television demands of using of controlling more, strengthen user's experience.
Description of drawings
Fig. 1 is the intelligent television terminal among the present invention and the handheld device handling process to incident.
Embodiment
The invention discloses a kind of method based on intelligent television terminal and handheld device realization virtual peripheral, the peripheral hardware that solves present intelligent television terminal can not satisfy the problem of controlling needs.
Realize that virtual peripheral needs the two-way interactive of intelligent television terminal and handheld device, and be based on processing alternately that referring to Fig. 1, bring in from the handheld device client and to see that its handling process is: at first, the handheld device client-side program moves to incident; Search television terminal equipment then; After searching television terminal equipment; Selection needs the television terminal equipment of connection, promptly gets into mutual (catch the virtual peripheral incident, be sent to television terminal equipment according to specified format) with television terminal equipment; Accomplish alternately both sides, off device connected after event handling was accomplished;
From television terminal, its handling process is: at first, and the operation of the oracle listener of television terminal; Monitor the peripheral hardware state, when set up with being connected of certain handheld device after, obtain the virtual peripheral incident from this handheld device; Then the virtual peripheral incident is converted into discernible system standard incident, writes the respective drive program, last incident is transferred to the upper strata interactive frame and is handled; Accomplish alternately, off device connected after event handling was accomplished.
With embodiment scheme of the present invention is done further to describe below.
Enforcement platform in this example is based on the Android system, and its concrete steps are following:
1) selects the ethernet communication port numbers.Be television terminal monitoring program and port numbers of handheld device client-side program selection, scope 1024 ~ 65536.
2) start television terminal virtual peripheral monitoring program.Monitoring program is moved with the mode of Android Service, the port of appointment is carried out event-monitoring, through IBinder interface and other component communication of system.
3) data transmission format of definition information interaction.Use XML definition transmission data format, be divided into device description file, service description file, event description file.The device description file form:
<device>
<name>Device name</name>
<id>Equipment id number</id>
<servicelsit>
<service>Service is provided</service>
</servicelsit>
</device>
The service description file form:
<service>
<type>COS: touch-screen, gravity sensor, gyroscope</type>
<id>COS numbering: 0,1</id>
</service>
The event description file
<eventlist>
<event>
<name>Incident title: connect, send</name>
<id>Case Number: 0,1</id>
</event>
</eventlist>
4) start handheld device virtual peripheral client application, search for the television terminal equipment in the same network segment automatically.The broadcast that the every other equipment of client-side program in local area network (LAN) sends specified format, according to the feedback result of listening port, the television terminal that discovery can connect.
5) connect television terminal equipment.The handheld device client-side program as required, the television terminal equipment that selection will connect.
