Fig. 4 is that video data processing system 30 carries out the flow chart that video data is processed.In step S301, comparator 34 receives the first frame picture, and processor 35 is set as reference picture Pr with the first frame picture and is temporary in buffer 33 with reference to picture Pr.
In step S302, comparator 34 receives next frame picture P, and whether the reference picture Pr in this next frame picture P and buffer 33 is relatively both more identical to determine.If both identical, flow process goes to step S303, otherwise flow process goes to step S304.
In step S303, this processor 35 this next frame picture of deletion P, and a time-delay mark is set in this reference picture Pr, then flow process is returned to step S302.
In step S304, this processor 35 judges whether the reference picture Pr in buffer 33 has been sent to encoder 36 and has encoded.If so, flow process goes in step S305, otherwise flow process goes to step S306.
In step S305, whether comparator 34 further determines difference between this next frame picture P and reference picture Pr less than predetermined value, if the difference both less than predetermined value, flow process goes to step S307, otherwise flow process goes to step S308.
In step S306, this processor 35 is sent to encoder 36 with the reference picture Pr in buffer 33 and encodes, and after this flow process goes to step S305.In the present embodiment, this processor 35 is after being sent to encoder 36 with the reference picture Pr in buffer 33, processor 35 arranges a status indication in the header file of this reference picture Pr, so, this processor 35 can determine whether this reference picture Pr has sent encoder 36 to and encoded by the status indication in the header file of reference picture Pr.
In step S307, this processor 35 selects a pixel as the reference pixel from this next frame picture P in the zone not identical with this reference picture Pr, and the coordinate of this reference image vegetarian refreshments of storage in this next frame picture P, this processor 35 is with pixel deletion identical with this reference picture Pr in this next frame picture P, this processor 35 also arranges one and merges mark in the picture P that this is compared, and this next frame picture P is sent to encoder 36 encodes.After this, flow process is returned to step S302.
In step S308, this processor 35 is set as reference picture Pr with the next frame picture, and this reference picture Pr is temporary in buffer 33.After this, flow process is returned to step S302.
In the present embodiment, video data processing system 30 also comprises decoder 38 and frame buffer 39.When the video data of user's Selective storage in memory 37 play, playing flow as shown in Figure 5.
In step S401, processor 35 response users' input and then video file in read memory 37 is sent to decoder 38 with the video file that reads and decodes.
In step S402, processor 35 obtains the first frame picture and this first frame picture is sent to frame buffer 39 from the sequence of frames of video of decoder 38 decodings, and this first frame picture is being presented on display 40 through after digital-to-analogue conversion.This processor 35 is set as reference picture with this first frame picture.
In step S403, processor 35 judges in this first frame picture whether comprise the time-delay mark, if include the time-delay mark, flow process goes to step S404, otherwise flow process goes to step S405.
In step S404, processor 35 obtains the next frame picture after certainly obtaining N the predetermined time interval that the first frame picture begins, and wherein N is for the quantity of time-delay mark, in this process, and the first frame picture of storage in display frame buffer 39 always on display 40.After this, flow process goes to step S405.
In step S405, this processor 35 obtains the next frame picture after certainly obtaining N+1 the predetermined time interval that reference picture begins.
In step S406, this processor 35 judges in this next frame picture whether comprise the merging mark, if comprise the merging mark, flow process goes to step S407, otherwise flow process goes to step S408.
In step S407, this processor 35 reads the coordinate of the reference image vegetarian refreshments in this next frame picture, then this next frame picture and reference picture are merged generation one merging picture, wherein the specific pixel in this next frame picture is selected the pixel corresponding with the coordinate with the reference image vegetarian refreshments in this reference picture and is coincided, and this processor 35 should merge picture and be sent to this frame buffer 39.After this, flow process is returned to step S405.
