Background technology
Along with the development of home network, the intelligent appliance of household long-range user interface (RUI) technology is increasingly by consumer
Favor, the particularly development trend of household long-range user interface apparatus intelligent appliance especially.The most a lot of normal structures are all in research
The method of home network device interconnection, is also proposed many standards and communication protocol, such as UPnP(Universal Plug and
Play), DLNA(Digital Living Network Alliance), IGRS(Intelligent Grouping and Resource Sharing)
Deng.
In home network, remote subscriber interface (RUI) technology, RUI terminal can obtain user interface from RUI service end,
By the user interface presentation that gets out, user can be by the equipment of user interface control RUI service end for RUI terminal.But
It is that above-mentioned remote subscriber interface technology is merely able in home network use, outside home network, RUI terminal and RUI service end
Can not mutually access, have impact on using effect, reduce user experience.
Summary of the invention
The invention provides a kind of method of user interface apparatus communication inside and outside home network, make the user interface outside home network eventually
End can be operated by the interface of the subscriber terminal equipment in home network, to improve the operating experience of user, facilitates user
Use.
The method of user interface apparatus communication inside and outside home network of the present invention, including:
A. in home network, the service end being connected and visual user interface terminal it are provided with, by described visual user interface eventually
End connects with the user interface apparatus in home network, and described service end connects the user interface terminal outside home network;
The service end request in home network of the user interface terminal outside the most described home network connects user circle in home network
Face equipment;
C., after service end receives request, the user interface apparatus specified it is connected to by visual user interface terminal, and to this user
Interface equipment request user interface, is sent to the user interface that user interface apparatus returns outside described home network by service end
User interface terminal;
D. in the interface terminal of family, the user interface received is shown.
Visual user interface terminal is used for mutual with the service end in home network, obtains and supports remote subscriber interface in home network
Equipment;Service end is the connection bridge inside and outside home network, is responsible in the user interface terminal outside home network and home network
User interface apparatus between communication, thus the interface data of the user interface apparatus in home network can be transferred to family
In user interface terminal outside network, user interface terminal is enable to be operated by the user interface of user interface apparatus.
Concrete, in user interface terminal before service end sends connection request, in visual user interface terminal scanning home network
The user interface apparatus of all support user interface capabilities, and generate user interface apparatus table;According to UPnP protocol, often
It is deleted from user interface apparatus table by the effect duration of individual user interface apparatus to after date.
Further, visual user interface terminal also monitors the notice of the user interface apparatus in home network, according to described notice
Judge if in the existing device in described user interface apparatus table, then update the effect duration of this user interface apparatus, otherwise
The user interface apparatus given notice adds in user interface apparatus table;If visual user interface terminal receives user interface and sets
Standby cancellation notice, then delete this user interface apparatus from user interface apparatus table.
Further, when described user interface apparatus table updates, or visual user interface terminal receives user circle in home network
After the update notification of face equipment, sending update notification by service end user interface terminal outside home network, user interface is eventually
Termination responds after receiving described notice accordingly.
Concrete, the user interface terminal outside family connects described by the way of DDNS (DDNS) and port mapping
Service end.
The method of user interface apparatus communication inside and outside the home network of the present invention, it is possible to make the user interface terminal outside home network lead to
Cross the communication that the subscriber terminal equipment in home network is well on, and utilize the user interface of subscriber terminal equipment to operate,
It is effectively increased the operating experience of user, and the most convenient for users to use.
Below in conjunction with the detailed description of the invention of embodiment, the foregoing of the present invention is described in further detail again.But should not
This is interpreted as, and the scope of the above-mentioned theme of the present invention is only limitted to Examples below.Without departing from the idea case in the present invention described above,
The various replacements made according to ordinary skill knowledge and customary means or change, all should be included within the scope of the invention.
Detailed description of the invention
The method of user interface apparatus communication inside and outside home network of the present invention, including:
A. in home network, the service end being connected and visual user interface terminal it are provided with, by described visual user interface eventually
End connects with the user interface apparatus in home network, and described service end connects the user interface terminal outside home network;
The user interface apparatus of all support user interface capabilities in visual user interface terminal scanning home network, and generate use
Family interface equipment table;According to UPnP protocol, each user interface apparatus has an effect duration, at each user interface apparatus
Effect duration to after date, it is deleted from user interface apparatus table.Visual user interface terminal also monitors the user in home network
The notice of interface equipment, judges if in the existing device in described user interface apparatus table according to described notice, then updating should
The effect duration of user interface apparatus, otherwise the user interface apparatus given notice is added in user interface apparatus table;If it is empty
Intend user interface terminal and receive the cancellation notice of user interface apparatus, then this user interface apparatus is deleted from user interface apparatus table
Remove.
User interface terminal outside the most described home network connect by the way of DDNS (DDNS) and port mapping and to
Service end request in home network connects the user interface apparatus in home network;
C., after service end receives request, the user interface apparatus specified it is connected to by visual user interface terminal, and to this user
Interface equipment request user interface, is sent to the user interface that user interface apparatus returns outside described home network by service end
User interface terminal;
When described user interface apparatus table updates, or visual user interface terminal receives in home network user interface apparatus more
After new notice, sending update notification by service end user interface terminal outside home network, user interface terminal receives institute
Respond accordingly after stating notice;
D. in the interface terminal of family, the user interface received is shown.
