For addressing the above problem, the technical solution of the utility model is:
A kind of remote virtual machine control system for screen display, described control system comprises virtual machine host, for receiving and dispatching and virtual machine terminal control unit and the virtual machine terminal display of network data information, virtual machine terminal control unit is connected with virtual machine terminal display, virtual machine host is connected with virtual machine terminal control unit is long-range by network, in virtual machine host, be at least provided with a video card, described control system also comprises for transmitting and process the virtual machine display control module of video card output signal, the input end of virtual machine display control module is connected with the output interface of video card, the output terminal of virtual machine display control module is connected with virtual machine terminal control unit is long-range, described virtual machine display control module comprises data processing unit for video card output signal being processed into picture signal frame, for the data compression unit of compressing image signal frame with for the network adapter of remote data transmission, data processing unit, data compression unit and network adapter are connected in turn, the input end of data processing unit is connected with the output interface of video card, and the output terminal of network adapter is connected with virtual machine terminal control unit is long-range.
Preferably, in described data processing unit, be provided with for converting the simulating signal of video card output the analog to digital converter of digital signal to and for video card output signal being processed into the data processor of picture signal frame, analog to digital converter is connected in turn with data processor, the input end of analog to digital converter is connected with the output interface of video card, and the output terminal of data processor is connected with data compression unit.
Be compared to prior art, remote virtual machine control system for screen display of the present utility model shows by video card output interface and the teletransmission of virtual machine display control module the output signal of video card in virtual machine terminal display, thereby without returning virtual screen signal in the internal memory of virtual machine host, neither take host CPU resource, do not affect again the normal serviceability of video card, improved the performance of whole system and the compatibility of software.
Accompanying drawing explanation
Fig. 1 is the schematic block circuit diagram of the utility model remote virtual machine control system for screen display.
Embodiment
Below in conjunction with drawings and Examples, further describe the utility model, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, remote virtual machine control system for screen display of the present utility model comprises virtual machine host, virtual machine terminal control unit, virtual machine terminal display and virtual machine display control module, virtual machine terminal control unit is connected with virtual machine terminal display, and virtual machine host is connected with virtual machine terminal control unit is long-range by network.Virtual machine terminal control unit and virtual machine terminal display are used in conjunction with, virtual machine terminal control unit is received and dispatched by network and network data information, the signal that virtual machine terminal control unit receives by network and decompress(ion) is received, or by network, send in virtual machine host after the signal of processing user input.In virtual machine host, be provided with the conventional devices such as master cpu, internal memory, video card and network interface card, video card is one or more, the input end of virtual machine display control module is connected with the output interface of video card, the output terminal of virtual machine display control module is connected with virtual machine terminal control unit is long-range, by network, connects.
Virtual machine display control module is for transmitting and process video card output signal, in virtual machine display control module, be provided with data processing unit, data compression unit and network adapter, data processing unit, data compression unit and network adapter are connected in turn, the input end of data processing unit is exactly the input end of virtual machine display control module, the input end of data processing unit is connected with the output interface of video card, and the output terminal of network adapter is connected with virtual machine terminal control unit is long-range.Wherein, data processing unit is for being processed into picture signal frame by video card output signal, picture signal frame is that each frame signal represents a complete screen picture, data compression unit is for compressing image signal frame, data compression unit can adopt the special-purpose compression chip with video compression functionality, also can use universal cpu to compress by the mode of software program, the signal after compression is convenient to network and is transmitted, and Network adaptation is for remote data transmission.
