Embodiment two
The schematic flow sheet realizing the method for long distance wireless fidelity display that Fig. 2 provides for the embodiment of the present invention two, the method can be performed by the device realizing the display of long distance wireless fidelity, wherein this device can by software and/or hardware implementing, and the part that can be used as mobile device is built in mobile device.As shown in Figure 2, the method comprises:
The internet protocol address of step 201, acquisition display device.
Step 202, to display device transmitting channel set up request.
Step 203, after display device responsive channels sets up request, set up control channel between mobile device and display device and data transmission channel according to internet protocol address.
Display device will monitor network data after opening WFD function.When display device receive channel that mobile device sends set up request time, respond this channel and set up request, afterwards, mobile device will set up control channel between mobile device and display device and data transmission channel according to IP address.Control channel is used for control information transmission, concrete, and control information can comprise startup and share order, suspends and share order and share order etc. with stopping.Control channel connects to be set up based on ICP/IP protocol, effectively can ensure the reliability of control information; Data transmission channel is set up based on UDP/IP agreement, preferentially can ensure the real-time of transfer of data.
Mobile device sends startup by control channel to display device and shares order, and display device receives after this order will log-on data transmission channel, the audio/video flow wrapper that wait-receiving mode mobile device sends.
Step 204, obtain and encapsulate the audio/video flow data on mobile device, generating audio/video flow wrapper.
Concrete, mobile device captures the sound of image and the mobile device broadcasting that display screen shows as audio/video flow data, and encode to audio, video data based on udp protocol, encapsulation etc. operates and generate audio/video flow wrapper.

The embodiment of the present invention two is on the basis of embodiment one, further illustrate the process of establishing of control channel and data transmission channel and the transmitting procedure of audio/video flow wrapper, the method of the present embodiment can effectively ensure the real-time of the fail safe of the control information that control channel transmits and the audio/video flow data of data transmission channel transmission to promote user's experience.
Embodiment three
The schematic flow sheet realizing the method for long distance wireless fidelity display that Fig. 3 provides for the embodiment of the present invention three, the method can be performed by the device realizing the display of long distance wireless fidelity, wherein this device can by software and/or hardware implementing, and the part that can be used as mobile device is built in mobile device.As shown in Figure 3, the method comprises:
The internet protocol address of step 301, acquisition display device.
Step 302, to display device transmitting channel set up request.
Step 303, after display device responsive channels sets up request, set up control channel between mobile device and display device and data transmission channel according to internet protocol address.
The connectivity of step 304, detection connecting channel, arranges the data parameters initial value of audio/video flow according to connectivity.
Data transmission channel is set up based on UDP/IP agreement, preferentially can ensure the real-time of transfer of data, but transfer of data is insecure, there will be the situation of packet loss.When channel is just set up, whether the network condition of channel is well unknown, and network condition directly can have influence on the real-time Transmission of data, and the audio and video stream media that display device one side plays may occur Caton phenomenon when playing, and affects the normal use of user.Exemplary, mobile device can send the Internet packets survey meter (Packet Internet Groper, PING) order, is detected the connectivity of data transmission channel by statistics packet loss.Preferably, the congested value of available network describes the fine or not degree of connectivity, and network congestion value corresponding when connectivity is excellent is little, and network congestion value corresponding when connectivity is good is moderate, and network congestion value corresponding during connectivity difference is large.
The data parameters of described audio/video flow, specifically can comprise the parameters such as the frame per second of audio/video flow, resolution and code stream.Below be only described for resolution.When the connectivity of channel is good, when the real-time playing audio-video Streaming Media glibly of guarantee display device one side, the audio/video flow data that resolution is high can be transmitted; And when the connectivity of channel is poor, when the real-time playing audio-video Streaming Media glibly of guarantee display device one side, the audio/video flow data that resolution is low only can be transmitted.So, in advance by the network congestion value that resolution value is corresponding different respectively, like this, after the connectivity detecting connecting channel obtains network congestion value, the data parameters initial value of audio/video flow can be set according to network congestion value.
Step 305, obtain and encapsulate the audio/video flow data on mobile device, generating audio/video flow wrapper.
After obtaining the audio/video flow data on mobile device, carry out the operations such as encapsulation according to the data parameters initial value of the audio/video flow arranged in step 304 and generate audio/video flow wrapper.
Step 306, by connecting channel, audio/video flow wrapper is sent to display device, plays for display device.
The network congestion value that step 307, reception display device return, upgrades the data parameter value of audio/video flow according to network congestion value.
Display device is play in real time, and be also continual to the transmission of audio/video flow wrapper in data transmission channel, in this process, network condition may change at any time.In order to ensure that display device one side can both play from start to finish in real time glibly, can constantly according to network condition adjustment audio/video flow data parameter value.
Exemplary, listening state command information can be sent by mobile device by control channel, after display device receives listening state command information, calculate network congestion value by the packet drop that detects and case propagation delays.Concrete, audio/video flow wrapper transmits based on udp protocol in data transmission channel, udp protocol can be numbered audio/video flow wrapper in transmitting procedure, can distinguish that whether the sequencing receiving each wrapper is identical with sending order according to this numbering after display device receives audio/video flow wrapper, and the wrapper that specifically which is numbered is not received.If the wrapper having certain to number is not received, then illustrates that this wrapper lost in transmitting procedure, namely there occurs packet loss phenomenon; Number forward wrapper should first be received, numbering wrapper rearward should after be received, but when the time that a wrapper is received is more late than the scheduled time, illustrates and there occurs time delay phenomenon.Display device comprehensively the quantity of packet loss and the order of severity of case propagation delays can carry out the congested value of computing network.
The network congestion value calculated is returned to mobile device by control channel by display device, and mobile device upgrades the data parameter value of audio/video flow according to this network congestion value.Such as, when network congestion value is larger, illustrate that network condition is poor, reduce the resolution of audio/video flow; When network congestion value is less, illustrates that network condition is good, the resolution of original audio/video flow can be kept, or the resolution of suitable increase audio/video flow, to ensure that the user of display device one side obtains best viewing effect.
The embodiment of the present invention three is on the basis of embodiment two, add, according to network condition, the data parameters initial value of audio/video flow is set and the step of real-time update, ensure that user can both watch the audio and video stream media file of real-time smooth playing from start to finish, meet consumers' demand further, promote user's experience.
