Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Be illustrated in figure 1 mobile instructor in broadcasting's platform feature module diagram of the present invention, this move instructor in broadcasting's platform by service end,
Client, wireless router form；Wherein, mobile instructor in broadcasting's platform service end is made up of desktop computer or notebook computer, passes through
Run PC end program, set up service end, be used for providing data transmit-receive service, by receive from mobile instructor in broadcasting's platform client
Audio/video flow carry out transcoding and be saved on hard disk, select audio, video data to export on-the-spot giant-screen or direct broadcast service simultaneously
Device；Mobile instructor in broadcasting's platform client is made up of at least 2 smart mobile phones, by radio communication, with mobile instructor in broadcasting's platform service end
Set up the connection of audio/video flow；Wireless router is for setting up mobile instructor in broadcasting's platform service end with mobile instructor in broadcasting's platform client
It it is a WLAN, it is achieved the channel radio of one-to-many between mobile instructor in broadcasting's platform service end and mobile instructor in broadcasting's platform client
Letter；Data transmission between mobile instructor in broadcasting's platform service end and mobile instructor in broadcasting's platform client uses special communication protocol, moves
The forwarding controlling message between dynamic instructor in broadcasting's platform client and mobile instructor in broadcasting's Platform Server uses Transmission Control Protocol, makes control message
Can stably send, the forwarding of audio, video data uses Real-time Transport Protocol, to ensure real-time.
Fig. 2 show mobile instructor in broadcasting's examples of platforms illustraton of model of the present invention, and in the present embodiment, mobile instructor in broadcasting's platform is by computer
PC1, multiple smart mobile phone M1 ... Mn, wireless router, the direct broadcast server being positioned in wide area network and other outut device group
Become；Wherein, PC1 is notebook computer or desktop computer, is the service end of mobile instructor in broadcasting's platform, and multiple smart mobile phones are mobile instructor in broadcasting
Platform client, service end and client use the connected mode of one-to-many to complete radio communication, and wireless router is by PC1 and many
Individual smart mobile phone M1 ... Mn sets up into a LAN, and service end PC1 of mobile instructor in broadcasting's platform is by wide area network and live clothes
Business device is connected, and other outut device is directly connected with PC1 such as on-the-spot large-size screen monitors, it is possible to achieve local output.
After PC1 runs PC end program, set up a service end, it is provided that data receiver and forwarding service；Smart mobile phone
M1 ... after Mn runs APP, by running the Quick Response Code of program display on scanning notebook computer, sets up audio/video flow with PC1
Connection, the audio frequency number that APP in smart mobile phone obtains video data that on smart mobile phone, photographic head provides, mike provides
According to, and these data are transferred to PC1 by WLAN；The program of the upper operation of PC1, receives multiple smart mobile phone and is transmitted across
The audio/video flow come, resolves and shows multiple picture on program interface and be controlled receiving audio/video flow, selecting
On-the-spot large-size screen monitors or the picture of direct broadcast server and audio frequency are arrived in output eventually, meanwhile, the audio/video flow received are carried out transcoding preservation
On laptop hard.
Smart mobile phone client uses Unified coding mode to encode, and Video coding is H264, and audio coding is FAAC,
Smart mobile phone M1 ... need the when of connection between Mn with PC1 to carry out time check, i.e. add on the basis of audio/video flow
Timestamp is packaged into TS stream and is sent to notebook computer by Real-time Transport Protocol, by notebook computer decoding process, comprises the concrete steps that:
(1) smart mobile phone M1 ... Mn gathers audio, video data, is encoded into corresponding form, obtains current time stamp simultaneously, join
In TS stream information form；(2) it is sent to move instructor in broadcasting platform service end PC1 by TS stream by Real-time Transport Protocol；(3) service end PC1 connects
After TS flow data, the timestamp according to providing in TS stream information parses each frame audio, video data successively.
Smart mobile phone M1 ... use Transmission Control Protocol to complete to control message between Mn and PC1 and forward, to reach to control message
Stable transmission.
Mobile instructor in broadcasting's service end PC1, to receiving different Voice & Video data, is transcoded into unified form and sends extremely
Direct broadcast server, the processing method of its sound intermediate frequency is: 1) from the audio frequency of mobile terminal, mobile terminal uniform packing be encoded into
Faac is sent to service end；2) from the audio frequency apparatus on mobile instructor in broadcasting's platform service end, by dshow technical limit spacing audio frequency apparatus
And after being acquired, encode faac；3) from local audio-video document, resolution file is also encoded into faac；The processing method of video
It is: 1) from the video of mobile terminal, service end decide through consultation video resolution, mobile terminal is screened and is judged, reselection is most preferably divided
Resolution, becomes x264 to send to service end by video data encoding, and service end is handled differently for different resolution video data
After forward again；2) from local audio-video document, resolution file video section is also encoded into x264；3) from separate procedure etc.,
As for subprogram, such as PPT, it analyzed, and resolve re-encoding after conversion, need to carry out intercepting again for data such as screens
Coding.
The notebook computer of mobile instructor in broadcasting's server can choose the picture of the mobile terminal transmission of arbitrarily connection as main picture
Face exports.
