Step 201: be provided with frame per second tolerance thresholding Thd and detection time thresholding Tthd;
Can be according to current code stream type and image resolution ratio be provided with frame per second tolerance thresholding Thd and detection time thresholding Tthd; Also can be that system is provided with according to the tolerance to display effect flexibly; Can also be that the user is provided with voluntarily, for example, a Thd is set at first; When finding that the image continuity is relatively poor, turn down Thd, till satisfied.

Test point can be set equably, and its density has n test point in each Tthd, when each test point, detects F, Df and Hf, and the value of n can be provided with as required.
Step 203: calculating F-Df-Hf, whether judge this F-Df-Hf greater than Thd, is execution in step 204 then, if be provided with counter records F-Df-Hf continuously greater than the number of times of Thd, when this F-Df-Hf is not during greater than Thd, also needs execution in step 205;
Step 204: judge that in detection time thresholding Tthd whether F-Df-Hf is all the time greater than Thd, be execution in step 206 then, otherwise return step 202;
Judge whether all the time greater than method be, to think that then F-Df-Hf is all the time greater than Thd in detection time thresholding Tthd if the F-Df-Hf that calculates of F, Df and the Hf of n detection is all greater than Thd continuously.If be provided with counter, then explain that F-Df-Hf is all the time greater than Thd in Tthd during for n when the count value of counter.
Step 205: with the counting zero clearing of counter, execution in step 202 then.
Step 206: the decoder that be described this time can not be handled so many data volumes in real time, is oversaturated in the decoder end data, turns down image resolution ratio; So just reduced the data volume that decoder will be handled; The burden of host side is just little, and decoder solved in the unit interval and the data presented frame will improve, and promptly Hf can improve; F-Df-Hf has just reduced like this, thereby can reach the optimal display result of equipment; Gather vision signal with the image resolution ratio after turning down afterwards, as needs reset frame per second tolerance thresholding Thd and detection time thresholding Tthd, then return step 201, as not resetting Thd and Tthd, then return step 202.
This step can also be to inquire earlier whether the user need switch image resolution ratio and show the image continuity that obtains the best, is then to turn down image resolution ratio, is not the detection that then stops the frame per second Hf of frame per second F, frame losing numerical value Df and demonstration to current device.When whether the inquiry user need switch image resolution ratio, can also close stream and stop demonstration, after the user makes one's options, open stream again and show.
If be provided with counter records F-Df-Hf continuously greater than the number of times of Thd, also need be with the counting zero clearing of counter.
Because of Hf is the frame per second that the decoder of host side has been decoded and has been used to show, F-Df is the actual frame per second that should decode of obtaining of HOST, if the host side ability is enough strong, decoded frame per second should equal F-Df.But in fact, maybe be owing to the difference of host side ability, F-Df-Hf also is not equal to 0, and the frame per second that does not promptly also solve is not 0.If turn down image resolution ratio, the data volume that decoder will be handled is just little, and the burden of host side is just little, and therefore, decoder solved in the unit interval and the data presented frame will improve, and promptly Hf can improve, just F-Df-Hf has reduced like this.
