Under：
Step 101, receives the live video that first terminal sends, and determines the resolution ratio of live video.
Wherein, first terminal can be the terminal for shooting live video, such as main broadcaster's terminal.
In force, when certain main broadcaster starts broadcasting, the main broadcaster can click on choosing of starting broadcasting in the terminals such as mobile phone (i.e. first terminal)
Select, first terminal can then open shooting part (such as camera), by shooting part detection image data, so as to obtain the master
The live video broadcast, the live video that then will can be photographed is sent to server.Due to different terminals shooting performance not
Together, so, the resolution ratio of the live video that different terminals are photographed is also different, server receive first terminal transmission it is live
After image, the live video can be parsed, determine the resolution ratio of the live video, such as 720*1280, or 640*480.
Step 102, the ratio of resolution ratio and the corresponding reference resolution of default Datum identifier image according to live video
Value, determines target scale coefficient.
In force, reference resolution can be pre-set in server, reference resolution can be any by technical staff
Set, for example, reference resolution can support the highest resolution of shooting, such as 720* for mobile terminal at this stage
1280.Wherein, the relatively fractional value in resolution ratio is properly termed as horizontal pixel value, and the bigger numerical in resolution ratio is properly termed as vertically
