Please refer to the figure, which is a system block diagram of the implementation of the present invention. The 々: : is not shown in 100, for example - TV or - projector. In the :: 2:: Central Processing Unit (CPU) 110 is used to execute the : instruction. The central processing unit 110 is connected to a system record; it is used to store operational data during video and audio decoding. The display ^ 100 is communicated with the external audio-visual peripheral device via the video signal source 140, and the image signal source 140 inputs the image signal to the display device for playback by the central processing H 11G. The central processing unit (1) includes a counter (CQunter) 112, which is used to calculate the viewing time statistics of the image source No. 2 or the statistical value of the number of frames of the image frame, and is calculated by the counter i4〇. The statistical values that come out are stored in the flash memory 13〇 connected to the system memory. The first figure (A) shows a first preferred embodiment of the image source 14 〇 grouping mode. In the first preferred embodiment of the present invention, the image signal source 140 is represented by a video signal input terminal of the display device 100, and the grouping standard is based on the sound channel of the co-drying. Decide. For example, the C〇mp0nent video signal source 212, the S-Video video signal source 211 and the CVBS video signal source 213 can be classified into the first group 141, and the 200810549 RGB shirt image signal source of the SCART connector 214, s-Vide〇 The image signal source and the CVBs image signal 'originally blamed the first group 142. In addition, in the same group, the image source with higher quality will be assigned a higher scanning priority order, for example, the scanning priority order of the image source in the first group 14 1 = according to the received image signal The enamel is arranged as a Component, such as a signal source>S-Video image source>CVBS image source, and the scanning priority of the image source in the second group is arranged according to the image quality of the received image signal. SCART RGB video signal source > SCART S-Video video signal source > SCART CVBS video signal source. A first preferred embodiment of the image source grouping method according to the present invention is shown in the third diagram (A). The second diagram (B) shows a second preferred embodiment of the image source 14 〇 grouping. In the second preferred embodiment of the present invention, the image signal source 14 is represented by the video signal input terminal of the display device 1 , and the parent video signal source forms a group. In this embodiment, the image source 140 includes, for example, a c(10)p0nenf video source 212, an S-Video video source 2A, a CVBS video source 213, and a SCART video source 214. A preferred embodiment of the image source grouping method according to the present invention is shown in the third diagram (b). The fourth diagram (A) is an operation flowchart of the main program of the television signal scanning method of the present invention. The fourth diagram (B) is an operational flowchart of the subroutine A in the fourth diagram (A). The program steps of the scanning method of the television signal of the present invention will be described below with reference to the fourth figure (A) and the fourth figure (B). 200810549 Step 4 0 1 : Start checking whether there is a reserved program to be played or last broadcast :, with signal input. At the beginning, the display device 1: first, check whether there is a reserved program to play or the last played image ^ source # video (4) person to the display device. If yes, proceed to step 403 to receive the video signal from the video signal source by the central processing unit (1) and decode it for playback. If no, proceed to step 4〇4. Step 404··Use the viewing time statistics value or the number of image frame playbacks. The statistical value is the standard to determine the scanning priority order of the image signal group. When the display device (10) is turned on, if there is no reserved program to be played or the last shot (4), the image source has no video operator, the central processing unit 110 will display the statistical value of the video source group or the number of video frames. The statistical value is a standard to determine the scanning order of the image source group. For example, in the preferred embodiment of the present invention, the C(10)P〇nent video signal source, the s_Vide〇 video signal source, and the CVBS video signal source are grouped into the first group, and the RGBscm connector RGB image signal The source, s-xianxian video signal source and (10) video signal source are classified into the second group. The central processing unit compares the total of the viewing time statistics of each image source in the first group, the sum of the statistical values of the sum or image frame, and the total of the viewing time statistics of each image source in the second group or the image frame. The sum of the number of statistics is played, and the higher scan priority is assigned to the video source group with the higher the statistical value of the viewing time or the number of the video frames. In the same group of money, the image source of the signal signal is scanned. 11 200810549 The priority order is based on the image quality of the received image signal.

In the second preferred embodiment of the present invention, each of the video signal sources becomes a group. In this way, the central processing unit 110 only needs to compare the viewing time statistics of each image signal source or the statistics of the number of image frames to determine the scanning priority order of the image source group. In the preferred embodiment of the present invention, the viewing time statistics or image frame playback statistics of the horse image source group are calculated by the counter 112 and recorded in the flash memory 130. Next, proceed to step 4〇5. Step 405: Scan the group with the highest priority. In the step offset, the scanning priority order of the image (four) source group will be sequentially arranged. Connection: The private sequence is scanned by the source (4) of the image signal with the highest priority. Next, proceed to subroutine A. Referring to the fourth figure (β), it is the flowchart of the subroutine A in the fourth figure (A). Subprogram 8 is set to execute the scanning program of each ::image source in the same group. The program begins with the steps: The source of the image with the highest scan priority in the group is: Scan. In step A12, if the image source having the highest scanning priority order has an image signal input, the central processing unit 11 触 touches the image (4) from the image source and decodes it for subtraction. If the video signal source with ^ = scan priority has no video signal to enter the second step, step A21 is to scan by the source with the second highest scan priority. Scan the group image one by one according to this scanning priority order. Every 12 200810549

In step = An2, the image signal source with the lowest scan i and the first image has the image signal input. The central processor 11G receives the image from the image source and decodes it for playback. If the video source with the lowest scan priority order has no video signal input, the execution of subroutine A will jump to step +η+l and return the control executed by the program to the third program. ; Ming > , , ?, and the fourth figure (A), if there is no image source in the source group with the highest scanning priority order, there is image signal input::2=:4〇6 in order The image status number source group with the second highest scan priority is scanned. Then the execution of the program jumps to the sub-rights of the fourth figure (8). Since the program steps of the subroutine a are described before, they will not be described here.七田收 The main image is used according to the set scan priority order - each image signal source group " each image signal ^ signal input =. Then, the execution of the main program will come to step 1 409. The scan program of the video signal source with the low scan priority is taken. The video signal source is displayed in step 408. The TV program is scheduled to be played on the day. The execution of the main program ends. See Figure 5 (A), the source's viewing time statistics. Step of the fifth diagram (A) The calculation procedure of the first preferred embodiment of the video signal according to the present invention will now be described as follows: 200810549 Step 501: Start. Step 5 0 2: Cumulative Shadow Jun 邙 % Watch time cumulative gate interpolation. When the viewing time of the video signal source group is viewed (four), the standard of the scanning priority order of the source group can be used as the judgment time of the source of the image signal source to reach one, ^ mouth It can be set to "when the image is counted, the accumulated count of the count n can be seen as the cumulative threshold value of k. In the preferred embodiment, the statistical value is incremented. Set to !〇 minutes. When the display is displayed, the central signal source receiving image (not shown) will be activated to start recording two t-like images, and the timer will display the video source. time? Tiger source viewing time. When the value is depreciated, that is, 1 minute, the viewing time of the ^^疋 is accumulated in step 503. Step 5 0 3 ·•Checking the county is not right. No A h Λ , — Whether the source of the video signal being played is the source of the image signal played last time. If yes, proceed to ^疋 Otherwise, execute step 5G4 to cycle the execution of the program back to the beginning of the CPU and execute it again. m 令 亚 step = 505: the counter viewing time statistics, then the number of two predetermined time accumulation gate insertion step 5. 6 时间 time statistics stats add a further embodiment of step 506 , but do not check if the counter overflows. According to the present invention, the data of the two juices is limited to the data structure of the two bytes. Therefore, the maximum count that it can count is 14 200810549 and the value is 65535. If the counter value exceeds 65535, step 507 is executed. If the counter value has not exceeded 65535, step 504 is executed to display the timing of the device and jump back to the beginning to execute the program again. Step 507: Perform a statistical value proportional allocation subroutine or a weighted allocation subroutine. If the count value of the counter exceeds 65535, execute the reconciliation numerical proportional allocation subroutine or the statistical value weighted allocation subroutine. The program steps of the numerical proportional allocation subroutine or the statistical value weighted allocation subroutine will be matched with the flowcharts of the sixth and seventh diagrams in the bottom step 508 ^ see the fifth diagram (8), which is an image according to the present invention A second preferred embodiment (four) of the statistical value of the number of frames played by the source of the signal source. The program steps in Figure 5 (8) are now explained as follows: ^ Step 511: Start. Step 512. Accumulate the number of image frames played by the image source until the predetermined number of frames is played. In the second comparison, the statistical value of the number of image frames played by the image source group can be used as a criterion for determining the scanning priority order of the image source group. Therefore, it can be set that when the image frame of the video signal source plays a number of times - the predetermined number of playbacks is difficult to accumulate, the counting example can be counted, and the preset image frame rate is ^; the excitation of the TSC: grid can be set to 1800 Image frame (1 ^ ^ is 3〇fpS). , the number of image frames played by the NTSC-compliant DVD in 15 200810549 1 knife 4) is the number of predetermined image frame playback = accumulated value. When the display device _ receives the video signal from the video source, the image frame count inside the central processing unit 11 is (not issued) and the number of video frames of the video source is recorded. When the number of image frame playbacks of the image source has reached the predetermined image frame playback number cumulative pinch value, that is, 1_ frame, then step 513 is performed. Step 513: Check if the source of the video signal currently being played is the source of the video signal that was played last time. If yes, proceed to step 515; otherwise, step 514 is executed to zero the image frame counter inside the central processing unit (10) and jump back to the beginning of execution of the program. *Step 515: Add 1 to the statistical value of the number of frames of the counter. If the number of image frame playbacks of the image source has reached the predetermined frame accumulation threshold, the number of frames of the count n is counted as a value = 1 plus one. Next, step 51 6 is performed. Step 516: Check if the counter overflows. According to a preferred embodiment of the present invention, the counter is composed of a data structure of 2 bytes, but is not limited thereto. Therefore, the maximum count value that it can count is 65535. If the counter value exceeds β5535, then step 517 is executed; if the counter count value has not exceeded 65535, step 514 is executed to reset the image frame counter of the display device to zero and execute the program back to the beginning to re-execute. Step 517: Perform a statistical value proportional allocation subroutine or a weighted allocation subroutine. If the count value of the counter exceeds 65535, the execution statistics 16 200810549 Numerical proportional allocation subroutine or statistical value weighted allocation subroutine. The procedure of the statistical numerical scale assignment subroutine or the statistical value weighted assignment subroutine will be explained below in conjunction with the flowcharts of the sixth and seventh diagrams. Step 518: Ending the sixth figure (A)' is a flowchart of the first embodiment of the statistical value ratio allocation subroutine according to the present invention. The program steps of the subroutine of the sixth figure are now explained as follows: Step 601 ··Start. Step 602··Reset the viewing time statistics of the image source group with the lowest viewing time statistics. In this embodiment, the image signal sources are grouped by the grouping method as shown in the second figure (B), and it is assumed that the S-Video image source group has the lowest viewing time statistics, that is, the user is less via the s_Video. The video signal source inputs the video signal for viewing. Therefore, the viewing time statistics of the S_Vide〇 video source group will be reset to zero. Next, proceed to step 6〇3. Step 603: Obtain a new viewing time statistics value by multiplying the viewing time statistics of the other video signal source groups by a fixed ratio. For example, other image source groups other than the S-Video image source group with the lowest viewing time statistics, including the CVBS image source group, the SCART image source group, and the C(10)P〇nent image signal. The viewing time statistics of the source group are set separately with the results of a fixed ratio «' and I are multiplied: CVBS image source group, SCART video source group, and 17 200810549 values. The new viewing time of the C (10) ponent video source group is counted down to step 604. ' ° : Step 604: Reset the viewing count value of other video source groups. In this step, when the video source group and the video source group are viewed by i C(10)_ent video source group: the value will be reset to zero. Next, proceed to step 6〇5. A 605: Set the new viewing time statistics value to the 苴他麦像源源组. The new viewing time value obtained in step _ will be set to U GVBS video source group, saRT video source group and C(10)p. The viewing time value of the thin t-image source group. Next, step 606 is performed. Step 606·· ends. Referring to Figure 6 (8), which is a flow chart of a second embodiment of a statistical value ratio assignment subroutine in accordance with the present invention. The program steps of the subroutine of the sixth figure (8) are now explained as follows: Step 601 ··Start. Step 612: Reset the statistical value of the number of playbacks of the lowest image frame. The statistical value of the number of image frames played by the source group of the image signal source. In this example of the yoke, the image signal, the knives, and the S-v丨deo image source group have the lowest number of image frames played by the grouping method as shown in the second figure (B). The statistical value, that is, the user inputs the image signal through the S Video image signal source for viewing. Therefore, the statistics of the number of image frames played by the s-Video source group will be reset to zero. Next, step 613 is performed. 18 200810549 Step 613: Obtain a new statistical value of the number of video frame play by multiplying the number of video frame play counts of other video source groups by a fixed ratio. For example, other groups of image signal sources other than the S-Video image source group having the lowest number of image frame play counts, including CVBS image source group, § CART image source group, and C(10)ponent image The number of image frame play counts of the signal source group is multiplied by a fixed ratio, and the multiplied result is set as a new image of the CVBS image source group, the SCART image source group, and the C(10)p0nent image source group. The number of frames played is statistical. Next, proceed to step 6丨4. Step 614: Reset the statistics of the number of image frames played by other image source groups. In this step, the statistics of the CVBS image source group, the SCART video source group, and the c〇mp〇nent image source group are reset to zero. Next, proceed to step 615. Step 615: Set the statistics value of the new image frame to the other image source group. The new image frame = text number obtained in step 613 is set to the number of video frame play counts of the CVBS video source group, the eight-play video source group, and the C (10) ponent video source group. Next, step 616 is performed. 7 Step 616: End. - Refer to Figure 7 (A), which is a flow chart of a first preferred embodiment of a statistical weighted allocation subroutine. The sequence steps of the subroutine of the seventh diagram (Α) are now described as follows: 19 200810549 Step 701: Start. v know 7 0 2 · Respect the viewing time statistics of the image source group with the low viewing time statistics. In this embodiment, the image source is grouped by the grouping method as shown in the second figure (B), and the false S S-Video image signal group has the lowest viewing time statistic 'that is, the manufacturer has less The s_VideQ video source inputs the video signal for viewing. So s_Vide. The viewing time statistics of the image source group will be reset to zero. What are the next steps? 〇 3. Step 7G3: Obtain a new viewing time count value by multiplying the viewing time statistics of other image source groups by an individual weighting index. In this embodiment, the inter-statistical values of the CVBS video signal source group, the SQM video signal source group, and the C(10) ponent video signal source are multiplied by their respective weighted indices, and the phase result is set as the CVBS video signal source group. The new viewing time of the group, SCART video source group, and C〇mponent video source. Next, step 704 is performed.乂 704 • Reblessly count the number of frames played by other video source groups. In this step, the (10)s video source group, SCART video source group, and ^(10) will be reset to zero for the viewing time statistics of the video source. Next, proceed to step 705. Step 705: Set the new viewing time statistics value to the group of the image source. The new viewing time = value obtained in step 7G3 sets the viewing time statistics of the u cm video signal source group, the sgart video signal source 20 200810549 group, and the c (10) P〇nent video signal source group. Next, step 706 is performed. Step 7 0 6 : End. - Please refer to the seventh diagram (B), which is a flow chart of a second preferred embodiment of the statistical value weighted allocation subroutine. The program steps of the subroutine of the seventh diagram (B) are now explained as follows: Step 711: Start. Y騄71 2 ·The number of statistics with the lowest number of frames is the same. 2 The number of frames of the image source group is counted. In this embodiment, the image signal source is grouped into groups according to the grouping method of the second figure (8), and the s_Video image source group has the lowest number of image frame play counts, that is, the number of users is small. Input the image signal through the S Video shirt to view the video. Therefore, the statistics of the number of image frames played by the S-Video image source group will be reset to zero. Next, proceed to step 713. Step 713: Obtain a new image display value by multiplying the number of image frame play counts of other image signal groups by an individual weighted index. In this embodiment, the (10) video signal source: the second CART video signal source group and the c〇mp〇nenshi video signal * the original number of the shirt frame play counts are respectively compared with their respective weighted indicators. The result of the multiplication is set as the post-history/1 image source group of the CVBS image source group and the new shirt image_number of the G〇mPGnent image source.
