Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment, technical scheme of the present invention is described in further detail.
Fig. 1 shows a kind of large screen display system, comprising:
1, a plurality of terminal devices 110: be used for providing the data stream of compressing resource;
2, control system 120: comprise controller 121, control desk 122, be used for receiving from terminal device the data stream resource of compress, pass through after treatment many data lines 130 with media data transmission to large-screen display equipment 140;
3, large-screen display equipment 140: the media data that receives is shown.
Fig. 2 shows the workflow diagram of this large screen display system, wherein:
1, step 201: control system listening port;
By listening port, thereby the information of the state of monitoring network, data mobility status and transmission over networks when having packet or request message to enter, judges whether its destination address is this control system.
2, step 202: have to connect to enter;
When the request message destination address that judgement receives is this control system, therefrom obtain client address information.
3, step 203: thereby create thread, receive the data stream of compressing;
When client attempted to be connected to control system, control system was distributed to the thread in thread pool the client of request access.At this moment, in the situation that there is available idle thread in thread pool, this idle thread is distributed to client., in the situation that there is no idle thread in thread pool, check the quantity that connects simultaneously., if the quantity that connects does not surpass the maximum quantity that connects when allowing, create a thread and this thread is distributed to client.Otherwise client awaits is until exist the thread that will distribute.The thread that use to distribute, set up data with client and be connected, the data stream of compressing from client.
The usage data library storage offers the state that the data of the Session ID (ID) of each client that just with control system, is being connected and client-requested are processed, as session information.Preferably, for each client, session id is set uniquely.
4, step 204: the media data after decompress(ion) is processed, formed virtual displaying scheme;
After receiving data stream, the data stream of compressing is decompressed, and send it to control desk 122 in control system `120, a plurality of data stream of 122 pairs of receptions of control desk control according to the user and stream attribute is processed, comprise splicing to a plurality of data stream, split, copy, the processing such as montage, form one or more virtual displaying schemes.
5, step 205: use a plurality of video cards to carry out conversion process to one or more virtual displaying schemes;
GPU(Graphics Processing Unit in each video card in a plurality of video cards) receive the virtual displaying scheme that enters, it is stored in video memory, and the virtual displaying scheme of storage is processed, include but not limited to that Transparent color is processed, played up, the processing procedures such as Deep Canvas, atomization, painted, this locality demonstration.
6, step 206: by many data alignment giant-screen equipment, provide data stream;
Use many data alignment giant-screen equipment that coordinate with a plurality of video cards that the data stream of processing through control system is provided.
7, step 207: the data stream that the giant-screen equipment interconnection is received shows.
, because the data stream through the data line input is processed through video card, be the signal that can directly show, so giant-screen equipment need not it is carried out further Graphics Processing and only needs directly to show and get final product.
Fig. 3 shows the controller structural map, and its middle controller 121 can be realized the switched-media flow data, and controls the function of the demonstration of giant-screen equipment, comprising:
Interchanger 301: listening port and receiving data stream, with the various forwarding data flows that receive to control desk 122.And from control desk 122, receive virtual displaying scheme.
Virtual screen equipment 302: according to the context of the virtual displaying scheme that receives, it is decoded, obtain the one or more virtual displaying scheme that forms in control desk, use a plurality of video cards to process it.
A plurality of video cards 303: the virtual displaying scheme that receives is changed driving.Each video card 303 comprises graphics card GPU, the graphics subsystem work of its compounding practice system.For the media stream data that receives, the processing that can be completed by graphics card GPU, transfer to graphics card GPU and process, and the processing that graphics card GPU can not complete, adjust back graphics subsystem, by graphics subsystem, completes this work.
Screen controller 304: provide sweep signal and traffic spike by many data alignment giant-screens, control the correct demonstration of large screen display.
Fig. 4 shows the structural map of control desk 122, and wherein control desk 122 can carry out assembly unit, fusion, control to the data stream that receives according to user's control and stream attribute.Comprise:
Receiver 311: mutual with controller 121, from controller 121 receiving media flow datas, and the virtual displaying scheme that will form sends back controller 121.
Mixer 312: the media stream data that receives is processed, include, but are not limited to such as fractionation, assembly unit, fusion, etc. processing, thereby form one or more virtual displaying schemes;
A plurality of virtual video card 313: one or more virtual displaying schemes further are split as a plurality of display parts, and one or more virtual displaying schemes are shown.This virtual video card uses Intel Virtualization Technology to realize the function of simulation video card in controller, and the graphics subsystem of compounding practice system is processed the media stream data that receives.Because virtual video card can arrange arbitrarily display parameter, so can produce high-resolution demonstration data.
By above step, having realized omitting existing giant-screen equipment is the needed multiple matrix device of translation data form, has reached analog-and digital-to comprising, the effect of the compatibility of the multi-signal forms such as SD and high definition, and overcome the problem of image fault.
Obviously, those skilled in the art can carry out various changes and modification and not break away from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of the claims in the present invention and equivalent technologies thereof, the present invention also is intended to comprise these changes and modification interior.
