Further, the statistical value calculating means 22 can calculate the statistical value by using one of the following three representative color models. The statistical value of the color model may be a statistical value of three primary colors (Red-Green-Blue, RGB), a statistical value of a dominant color difference (Y, Cb, Cr), or a statistical value of a bit depth. Since the bit depth can be 8-bit, 16-bit, 24-bit, 32-bit or 48-bit, the statistics of the color model included in the statistical value σ 异 I I 22 22 异 (N+1) frames Values can be calculated using any bit depth (such as 8-bit, 16-bit, 24-bit, 32-bit, or 48-bit). The color model conversion of the two primary colors and the known color difference is as follows: Υ: 0.299R + 0.587G + 0.H4B (1) Cb 0.168R-0.331G+ 0.449B (2) Cr: =0.5R-0.418 G-〇.〇81B (3) 8 200818928 where O7, Cb, Cr) is the color model representing the analog color difference & is the red ratio, and (R, G, B) is the three primary colors (red ^ = ^y). : The bit depth and the color model conversion of the three primary colors are as follows;; H wheel type table (ds) is called) n (4) where η is the silk number system, the fourth wire type is the color: the multiplication is ~, σ primary color 256 variations. The bit depth is a value of 24 bits, that is, the values of the two primary colors are the same, and the value of the 24-bit can be calculated as other bits (4) Qiao _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Benjamin: Whether the frame is a scene change frame. - On - Fine L L1 calculates the color model of the first deleted frame and counts the statistical value.

The (Ν+1) difference, for example, the difference (Ν+1) of Table 1 is (X(10))χΝ). Then, step sl3 〇 'Because the control value generator 2008 wheel 200818928 is connected to the output of the difference calculation device 24, the (10)) comparison value is generated according to the (10)) difference, and the (_ control value) The foot corresponds to the (10)th frame, wherein the first (ie, the control value changes with the (10)th frame) to form a parameter value of the dynamic switching instead of forming a fixed parameter value. Finally, as shown in step S140, the comparator 28 receives the _) control value generated by the comparison value generator %, and the (N+1) difference value generated by the touch value calculation means 24 to perform the (10)th) The difference is compared with the (N+1) control value. As the switching of the frame is switched to the corresponding parameter value by the comparison value instead of a fixed value, the comparator 28 is further more efficient in performing the ratio of A to #χ 'the towel to the h value is -gg The boundary value is used to determine whether the (10) 1) frame is a scene change frame. ... In the above comparison, if the (10)) difference is greater than the (10)) comparison value, then the (10)) is the scene change frame, and if the (+1) difference is less than the ((4) control value, the Qing (10)) frame is Non-28 (N+1 } (X(N+1) _Xn) ?

If it is judged, whether the jersey group is a scene change frame, so that the encoder can provide better quality audio and video rotation. Guan Zhuangming (4) The fifth figure is a schematic representation of the numerical calculation of the embodiment of the invention. The statistical value discriminating device 22 receives the fourth (fourth) frame outputted from the decoder 32 to produce the (N+1)th statistical value (as shown in FIG. 6A) according to the color of the fourth (fourth) frame and the core 3L. And output to the difference calculating means 24 difference. The tenth statistic 24 temporarily stores the Nth statistical value to generate a (_difference, wherein the (10)th) difference is based on the (N)th statistic value received by the Nth statistical value and the difference calculating means 24, such as the sixth b No. Further, the statistical value calculation means 22 may output a ((4)) sway to the difference value calculating means 24 by the sum of the (Ν +1)th statistic values for the difference calculating means 24 to suppress the Gaussian sum and the (Ml) The sum of the muse produces a - (Ν +1) Gaussian difference. The comparison value generator % generates the corresponding (Ν+1) threshold value according to the (4) high 4 difference value, so that the (10)) threshold value can be compared with the ((4)) Gaussian difference value of the health balance 28 , transform the frame with the side scene. 10 200818928 Referring to the seventh figure, it is a schematic diagram of numerical calculation of another digital data_device of the present invention.

Due to the coding technology of video and audio, the video format of the digital audio and video disc will increase by 〇·5 grids for every two frames, and every four shadows will increase—the grid will be formed, and the five frames will be formed. As shown in Table 3. In other words, the frame of the front end and the last end of the plurality of frames of Table 2 are not modified and sorted, and only the middle order of the plurality of frames is modified to form a table as shown in Table 3. 3 P. D0WM Sorting style. The high-order difference and the low-order difference between each of the shadows are calculated by the difference calculating means 24 according to the arrangement order shown in Table 3, and the calculation result of the difference between each of the frames is obtained.

The photo processor 26 is based on the set of high-order difference values output by the difference calculating means 24 and the generated second/generated set of high-order control values and the set of low-order control values. The comparison value generator 26 is outputted to the follower 28 with the group south order control value and the low value_illumination value. Comparator Shen 200818928 receives the 阿 group A step difference and the group lower order difference, and receives the set of high order control values and the set of low order pairs, ,, and values, and compares the set according to the set of 咼 对照The high-order difference value is compared, and the low-order difference value is compared according to the set of low-order control values to determine whether the format of the group of frames is correct by using two sets of comparison results. In this way, the comparison 28 receives the difference between each frame and its corresponding control value at the same time, and compares the difference control values to more quickly complete the secret: the detection of the frame format Can be more efficient. A flowchart of a second embodiment of the present invention. The present invention uses a digital greedy device to form a 2G side complex contact frame to determine whether a plurality of frames lose the format and must be corrected. 1 is as shown in step S21G, and the statistical value calculation means 22 is used to calculate the color-period of each of the plurality of frames and the per-most lower level to generate a plurality of high-order statistics and a plurality of low-order statistics. The values, for example, Τι to T4 shown in Table 2 are the high-order statistics of the first frame to the fourth frame of the division, and the & line is the lower-order statistical value corresponding to the first to fourth frames. Step S220, the difference calculating means 24 receives the plurality of high-order sigma values and the plurality of low-order values 'and respectively _ a plurality of high-order statistic values and the plurality of low-order statistic values for difference calculation to generate a plurality of The high-order difference and the complex low-order difference, for example, the statistical values of the plurality of frames are as shown in Table 2, wherein the color of the uppermost column is converted into a high-order statistical value, and the lowest color of the statistics is calculated. The Gu type is a low-order statistical value, and then the plurality of cells are sequentially read to the difference calculating device 24, such as a table-not-stated value, to calculate the statistical values of the difference calculating cells after the difference is calculated. The system is shown in Table 4. According to step S230: shouting a number of magnetic impurities and the plurality of low-order differences are transmitted to the control value generator %, and generating a comparison value in the format of Table 4 for each-high value and each-low-order difference value. , = 28, so that the comparator 28 compares the corresponding difference according to the comparison value of the dynamic change of the frame =: step up shadow, quality. Continuing, as shown in step S24, the comparator 28 receives the plurality of high-order sparse, and the low-valued values, the plurality of high-order control values, and the plurality of low-order pairs, and according to the plurality of cranes (four) N The order is compared with the lower-order difference of the Nth group to determine whether the format of the plurality of frames is wrong, and the frame is overwhelmed by the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The high_illumination value and the plurality of low_dividing periods break the complex difference value of the complex number frame and the lower order difference value, for example, the 3:2 pulldown mode of the L-audio disc. If the heart, the Ren-Difference does not meet the format of the control value, that is, if any difference is not as shown in Table 4, then the sentence "Decrease «彡 is the wrong type _ correction, if the difference is a simple comparison value ^ format 'that is, all the differences are shown in the format shown in Table 4, then the multiple frames are judged to be correct
