It is long that a new average image quality value and new video playing duration is calculated；
Wherein, the previously stored average image quality is zero when mobile terminal dispatches from the factory；During the previously stored video playing
Grow when mobile terminal dispatches from the factory also is zero.
The image quality size and previously stored average image quality and video playing duration calculation that basis in this step obtains obtain
Include to a new average image quality value and new video playing duration：
If a length of TA1 when previously stored average image quality is Vavg1, previously stored video playing, then new average image quality is
Vavg1=(Vavg* TT (x)+Vavg1* TA1)/(TT (x)+TA1), a length of TA1=(TT (x)+TA1) during new video playing；
Then TA1 and Vavg1 are stored and is calculated for next time.
For example, example is connected, if a length of TA1 when previously stored average image quality is Vavg1=8, previously stored video playing
=1000 seconds, then new average image quality is Vavg1=(Vavg* TT (x)+Vavg1* TA1)/(TT (x)+TA1)=(8*1000+5*
20)/(1000+20)=7.941, a length of TA1=(TT (x)+TA1) during new video playing=1020 seconds；Then by TA1=1020 second
It stores with Vavg1=7.941 and is calculated for next time.
S500, when next time carry out video playing need adapted video play image quality when, according to the average picture of precedence record
