Detailed description of the invention
Refer to shown in Fig. 1 to Fig. 4, a kind of intelligent terminal of the present invention plays the method for adaptive network during video, described method is: when smart machine starts or network environment changes, intelligent terminal obtains intelligent terminal's external IP by a server, play the external IP of the video source device of video, LAN port address and WAN port address; Judge that whether video source device (namely judges the LAN port address of video source device, WAN port address, if information behind the nat and the outside ip address of himself) after network address translation NAT; The information of described video source device seldom changes, and the information of video source device unified after login or network change can be reported to server to preserve, or is saved in video source device itself, waits that intelligent terminal initiates request and asks for.
After getting video source device information and intelligent terminal's external IP information, needs judge whether to need to initiate LAN mouth and the detection of WAN mouth, it is: when intelligent terminal is identical with the external IP of video source device end that two ends are in same LAN and initiate the detection of LAN mouth and the detection of WAN mouth the need of the condition initiating detection; When the external IP of intelligent terminal and video source device end differs, two ends not in same LAN and video source device not behind the nat, then equally initiate WAN mouth detection. Meet detection condition, initiate detection. In same LAN and video source device after network address translation NAT, intelligent terminal initiate respectively LAN mouth detection and WAN mouth detection, detection packet loss can use less than 30% link determined between intelligent terminal and video source device; When not at same LAN and video source device not after network address translation NAT, then initiate the detection of WAN mouth equally; Select the best link play according to result of detection, when the link that result of detection is corresponding is all unstable, select to be play by the link of server, it is ensured that play the stability of video. Described detection mode is UDP detection or Http detection; Described UDP detection is: initiate 10 UDP bags to destination address, and the content of UDP bag need to unified with video source device end be decided through consultation, receiving the response packet of more than 7 in Preset Time 3s, then detect successfully, LAN mouth or WAN mouth link can be used.
Two kinds of link LAN mouths of described detection and WAN mouth, when result of detection all can use, prioritizing selection LAN mouth link is play. When intelligent terminal or video source device end network environment change, the method that this adaptive network need to be re-executed.
In the present invention, video source device information is obtained from triggering, initiate to detect that the whole process obtaining result of detection is all asynchronous to be carried out, after change of network environment or equipment are restarted, the optimum link of acquiescence is the link play by server, avoid also waiting result of detection when playing, improve to play and experience.
Described obtain result of detection after, unified result of detection is saved in the buffer memory of intelligent terminal, quickly takes for when playing. Described intelligent terminal can be mobile phone, personal assistant, the one of the smart machines such as flat board.
Described video source device can be router, the one of the first-class gateway device of network shooting. When a certain link that detection is available is play unsuccessfully, the link play by server is switched to play out immediately.
When user clicks and commences play out, take the result of detection of buffer memory, quickly play according to optimum link.During the link that optimum link is non-to be play by server, playing after unsuccessfully, the link play by server of converting immediately, steadily excessively and revise the optimum link of buffer memory.
Three kinds of representative link topological diagrams as shown in Figures 2 to 4. Being the typical intelligent terminal AP and the LAN mouth by the direct-connected video source device of WIFI in Fig. 2, when WIFI connection signal is good, the detection of LAN mouth can be led to, and plays and plays the best by LAN port address; Fig. 3 is typical general home-network linkups mode: video source device WAN mouth is connected on the LAN mouth of egress gateways and connects outer net, and intelligent terminal passes through WIFI connection outlet gateway. When WIFI connection signal is good, now WAN mouth detection can be led to, and plays and plays the best by WAN port address. Being complicated network topology in Fig. 4, video source device connects behind the nat and with intelligent terminal not in same LAN, and test detection is unavailable, plays link and plays the best by server. If the situation video source device in Fig. 4 connects not behind the nat, then need to initiate the detection of WAN mouth, then determined optimum broadcasting link by result of detection.
In a word, the present invention obtains intelligent terminal's external IP by a server, plays the external IP of the video source device of video, LAN port address and WAN port address; Judge that video source device is whether after network address translation NAT; And learn that whether the two is at same LAN by the external IP comparison of intelligent terminal's external IP and video source device, best broadcasting link can be selected by current network environment, effectively accelerate intelligent terminal and play the speed of video, reduce the pressure of server, improve Consumer's Experience.
