Embodiment
Often need be equipped with computer or handheld device in the prior art and control remote computer, be not easy to the use of average family, and have the higher problem of cost with remote control function.
Nowadays, STB is used widely in average family, and present embodiment adopts STB to combine DTV to control remote computer, uses convenient; Owing to need not be equipped with special remote control computer or handheld device, help the control of cost in addition.
Below in conjunction with specific embodiment and accompanying drawing the present invention is described further, but should limit protection scope of the present invention with this.
Fig. 1 shows the overall structure figure of the remote computer control system of present embodiment, mainly comprises remote computer 11, STB 12 and DTV 14.
Wherein, STB 12 is coupled through communication network 13 with remote computer 11.Communication network 13 can be cable network, wireless network etc., is mainly used in the data interaction between STB 12 and the remote computer 11.
Communication protocol between STB 12 and the remote computer 11 can adopt multiple mode, and what adopt in the present embodiment is virtual network computer (VNC) agreement.Concrete, operation VNC client-side program in the STB 12, and move the VNC server on the remote computer 11, thus realized the data interaction of the two.It will be understood by those skilled in the art that in other specific embodiments, also can adopt other suitable modes to realize the data interaction between the two.
STB 12 also comprises keyboard/mouse interface, is used to connect keyboard 15 and mouse 16, and this keyboard/mouse interface can be a special purpose interface, also can adopt USB (USB) interface etc.Those skilled in the art should be understood that; Driver and the driver module that can support keyboard 15, mouse 16 also are installed on the STB 12; Make user 10 to operate, be specially in the present embodiment and send the input operation data through keyboard 15, mouse 16.
STB 12 obtains the graphical interfaces data of remote computer 11 through communication network 13, i.e. the relevant data of graphical interfaces of remote computer 11 current demonstrations outputs.STB 12 transmits it to DTV 14 and shows after receiving these graphical interfaces data, makes user 10 to see the display interface that remote computer 11 is current through DTV 14.Before transmission, remote computer 11 can leak to prevent significant data the graphical interfaces data of transmission are encrypted, and STB 12 is at first deciphered after receiving data, redispatches afterwards to DTV 14 to show.
In addition; STB 12 also obtains user 10 input operation data; The graphical interfaces that is promptly shown for current digit TV 14, user 10 sends through external input devices such as keyboard 15, mouses 16 and controls instruction, and each is controlled instruction and converges into the input operation data and by STB 12 receptions.Afterwards, STB 12 is sent to remote computer 11 with the input operation data that receive and handles and respond.In order to realize function of keeping secret, STB 12 can also be encrypted it before sending the input operation data equally, and remote computer 11 receives after the input operation data of encryption, at first deciphers, and then handles accordingly and operate.
Fig. 2 shows the detailed block diagram of the remote computer control system of present embodiment, and wherein, STB 12 specifically comprises: remote interface module 121, demonstration output module 124, operation acquisition module 125, figure accelerating module 123 and encryption and decryption module 122.
Concrete, remote interface module 121 is used for carrying out data interaction with remote computer 11, comprises the graphical interfaces data of obtaining remote computer 11, and the input operation data of user's input are forwarded to remote computer 11.
Encryption and decryption module 122 is used for the graphical interfaces data that receive from remote computer 11 are deciphered (if the graphical interfaces data are through encrypting), and the graphical interfaces data after the deciphering are sent to figure accelerating module 123.In addition, encryption and decryption module 122 also is used for the input operation data that operation acquisition module 125 obtains are encrypted, and the input operation data after will encrypting are sent to remote computer 11 through communication network.
Certainly, encryption and decryption module 122 is optional, in other specific embodiments, can not reach according to this to input operand also that the graphical interfaces data are encrypted, decryption processing, and directly original data sent and received.
Certainly; Figure accelerating module 123 also is optional; When the data volume of the graphical interfaces data of transmission hour; When perhaps DTV 14 had corresponding graphics process or accelerating module, STB 12 can not carry out figure to the graphical interfaces data to quicken, but directly forwards it to DTV 14.
Graphical interfaces data after demonstration output module 124 is used to will speed up are sent to DTV 14 and show.As a preferred embodiment; Show in the output module 124 and also comprise picture-in-picture submodule (not shown); Be used on the display screen of DTV 14 dividing a special viewing area (for example, the upper left corner of display screen, the lower left corner, upper right corner or the like), the graphical interfaces data are play in this viewing area; Realize " picture-in-picture " function, thereby in the process of controlling remote computer 11, do not influence the broadcast of normal tv program.
In the present embodiment, adopt STB 12 to obtain remote computer 11 and show the graphical interfaces data of output, and be forwarded to DTV 14 and present to the user, the display frame that is about to remote computer 11 is presented on the DTV 14.In addition, STB 12 also obtains user's input operation data, and forwards it to remote computer 11 and handle and respond.Owing to need not be equipped with special computer, handheld device in the present embodiment, utilize STB and DTV commonly used in the average family to realize controlling of remote computer, use more conveniently, and help reducing cost.
Present embodiment also provides a kind of remote computer control method based on DTV, specifically sees also Fig. 3, comprising:
Step S31, STB obtain the graphical interfaces data of remote computer;
Step S32 shows said graphical interfaces transfer of data to the DTV that links to each other with said STB;
Step S33, said STB obtain user's input operation data;
Step S34 is forwarded to said remote computer to respond with said input operation data.
About more details of this remote computer control method, please refer to the detailed description of the course of work of previous embodiment medium-long range computer operating system, repeat no more here.
Though the present invention with preferred embodiment openly as above; But it is not to be used for limiting the present invention; Any those skilled in the art are not breaking away from the spirit and scope of the present invention; Can make possible change and modification, so protection scope of the present invention should be as the criterion with the scope that claim of the present invention was defined.
