In this step S10, the video resolution in the preset direction of the received video data is analyzed. The video resolution in the preset direction can be horizontal video resolution, vertical video resolution, or horizontal video resolution and vertical video resolution. video resolution. That is, in this step, the horizontal video resolution of the received video data can be analyzed, the vertical video resolution of the received video data can also be analyzed, and the horizontal video resolution and vertical video resolution of the received video data can also be analyzed simultaneously. The video resolution is the height/width pixel value of the video.

S11. The display terminal acquires the physical resolution in the preset direction, and analyzes whether the obtained physical resolution in the preset direction is equal to the analyzed video resolution in the preset direction. If not, execute step S12; if they are equal, execute step S11. S14.

In this step S11, the display terminal obtains its physical resolution in a preset direction, and the preset physical resolution in a direction can be a horizontal physical resolution, a vertical physical resolution, or a horizontal physical resolution and a vertical physical resolution. Rate. That is, in this step, the horizontal physical resolution of the display terminal, the vertical physical resolution of the display terminal, or the horizontal physical resolution and vertical physical resolution of the display terminal may be obtained. The preset directional physical resolution may be pre-stored in the memory of the display terminal, or may be stored in the background server of the display terminal (that is, the display terminal may read the preset directional physical resolution from the background server).

In this step S11, analyze whether the acquired preset direction physical resolution is equal to the analyzed preset direction video resolution, such as whether the analyzed acquired horizontal physical resolution is equal to the analyzed horizontal video resolution, whether the analyzed longitudinal physical resolution Whether the resolution is equal to the resolved portrait video resolution.

S12. The display terminal adjusts the video resolution in the preset direction of the video data according to the ratio of the parsed video resolution in the preset direction to the acquired physical resolution in the preset direction, so that the video resolution in the preset direction of the video data can be resolved The rate is equal to the preset orientation physical resolution of the display terminal.

In this step, the display terminal adjusts the video resolution in the preset direction of the video data according to the ratio of the parsed video resolution in the preset direction to the obtained physical resolution in the preset direction. The resolution in the preset direction is adjusted by proportional enlargement, proportional reduction, non-linear enlargement or nonlinear reduction, and the above four types are selected according to the ratio of the resolved video resolution of the preset direction and the obtained physical resolution of the preset direction The appropriate adjustment method in the adjustment method.

S14. The display terminal outputs and displays the received video data to be played.

In this step S14, that is, when the video resolution of the received video data to be played in the preset direction is equal to the physical resolution of the display terminal in the preset direction (the video data to be played matches the display terminal), no Adjusting the video data to be played can directly output and display the video data to be played on the display terminal.

Referring to FIG. 2 , FIG. 2 is a schematic flowchart of a second embodiment of a video data display method of a display terminal according to the present invention.

Based on the first embodiment of the video data display method of the above-mentioned display terminal, the preset direction includes horizontal and vertical, and the method includes:

S20. When the display terminal receives the video data to be played, analyze the horizontal video resolution and the vertical video resolution of the received video data.

The display terminal can be a display terminal installed in large shopping malls, supermarkets, hotel lobbies, dining halls, theaters and other public places where people gather, or it can be other terminals with display functions, such as computers and mobile phones.

The display terminal can receive video data to be played from other devices through a USB interface and a USB data cable, and can also receive video data to be played through wireless communication, such as receiving video data to be played through Bluetooth or wifi.

In this step S20, the horizontal video resolution and vertical video resolution of the received video data are analyzed, and the video resolution is the height/width pixel value of the video. For example, it is analyzed that the horizontal video resolution of the received video data is 960, and the vertical video resolution is 540, that is, the video resolution of the received video data is: 960x540.

S21. The display terminal obtains its horizontal physical resolution and vertical physical resolution, and analyzes whether the obtained horizontal physical resolution is equal to the analyzed horizontal video resolution, if not, execute step S22, and if equal, execute step S23 .

In this step S21, the display terminal obtains its horizontal physical resolution and vertical physical resolution. For example, the horizontal physical resolution of the display terminal is 1920, and the vertical physical resolution is 1080. Rate: 1920x1080. In this step S21, it is analyzed whether the obtained horizontal physical resolution is equal to the analyzed horizontal video resolution, such as the obtained horizontal physical resolution is 1920, and the analyzed horizontal video resolution is 960, then it can be seen that the obtained The horizontal physical resolution and the analyzed horizontal video resolution are not equal, and the horizontal video resolution of the video data needs to be adjusted accordingly. For example, when the obtained horizontal physical resolution is 1920 and the analyzed horizontal video resolution is 1920, you can see It is found that the obtained horizontal physical resolution is equal to the analyzed horizontal video resolution, and there is no need to adjust the horizontal video resolution of the video data.

S22. Adjust the horizontal video resolution of the video data according to the first ratio N1 between the analyzed horizontal video resolution and the obtained horizontal physical resolution, so that the horizontal video resolution of the video data is consistent with the horizontal physical resolution of the display terminal The resolutions are equal; then step S23 is executed.

In this step S22, the horizontal video resolution of the video data is adjusted according to the first ratio N1 of the analyzed horizontal video resolution and the obtained horizontal physical resolution, and the adjustment includes the following situations:

The first case: if the first ratio N1 is greater than 1, and N1 is an integer value, then delete N1-1 pixels in every N1 horizontal pixels of the video data (that is, the horizontal video resolution of the video data scaled down). For example, when the resolved horizontal video resolution is 1920 and the obtained horizontal physical resolution is 960, then the first ratio N1 is 1920/960=2, and one pixel is deleted for every two horizontal pixels of the video data If the pixels in the horizontal row of the video data are A1, A2, A3, A4, A5, A6... A1919, A1920, then one can be deleted from the pixel points in pairs The first pixel in a group, or delete the second pixel in a pairwise group), such as deleting pixels A2, A4, A6...A1920, that is, deleting the pixels of even items, and finally retaining the odd items pixels, the horizontal video resolution of the adjusted video data is 960, which is the same as the acquired horizontal physical resolution. Preferably, in order to reduce the poor image transition caused by deleting pixels, the RGB colors of the retained pixels can be adjusted accordingly, such as the RGB colors of the retained pixels can be adjusted according to the original RGB colors of the retained pixels. and the RGB colors of the two adjacent pixels, such as R _An '=(R _A(n-1) +R _An +R _A(n+1) ), G _An '=(G _{A(n -1)} +G _An +G _A(n+1) ), B _An '=(B _A(n-1) +B _An +B _A(n+1) ), where: R _An 'represents the original pixel The adjusted R value of point An, RA _(n-1) represents the R value of the original pixel point A(n-1), _RA(n+1) represents the R value of the original pixel point A(n+1), G _An 'represents the adjusted G value of the original pixel point An, G _A(n-1) represents the G value of the original pixel point A(n-1), B _A(n+1) represents the original pixel point A(n-1) +1), B _An 'represents the adjusted B value of the original pixel point An, B _A(n-1) represents the B value of the original pixel point A(n-1), B _A(n+1) Indicates the B value of the original pixel point A (n+1).

The second case: if the first ratio N1 is less than 1, and 1/N1 is an integer value, then add 1/N1-1 pixels after each horizontal pixel of the video data (that is, for the horizontal The video resolution is scaled up and adjusted). For example, when the resolved horizontal video resolution is 960 and the obtained horizontal physical resolution is 1920, then the first ratio N1 is 960/1920=1/2, and 1/N1 is 2, then in each horizontal direction of the video data Add 1 pixel after the pixel. For example, if the pixels in the horizontal row of video data are A1, A2, A3, A4, A5, A6...A959, A960, then the pixels in A1, A3, A5, A7 Add pixels A1', A3', A5', A7'...A959' after ... A959 respectively, then the horizontal video resolution of the adjusted video data is 1920, which is the same as the acquired horizontal physical resolution. The RGB color of the added pixel is determined according to the RGB color of the two original pixels adjacent to the left and right, such as R _An' '=(R _A(n-1) +R _A(n+1) ), G _An' '=(G _A(n-1) +G _A(n+1) ), B _An' '=(B _A(n-1) +B _A(n+1) ), where: R _An' ' means The R value of the newly added pixel point An', _RA(n-1) represents the R value of the original pixel point A(n-1) on the left side of the newly added pixel point An', and _RA(n+1) represents the The R value of the original pixel point A (n+1) on the right side of the newly added pixel point An', G _An' 'represents the G value of the newly added pixel point An', G _A(n-1) represents the newly added pixel point An 'The G value and B A(n+1) of the original pixel point A _(n-1) on the left represent the newly added pixel point An' the B value and B _An of the original pixel point A(n+1) on the right'' means The B value of the newly added pixel point An', B _{A (n-1)} means the B value of the original pixel point A (n-1) on the left side of the newly added pixel point An', B _{A (n+1)} means the newly added The B value of the original pixel A (n+1) to the left of the pixel An'.

The third case: if the first ratio N1 is greater than 1, and N1 is a non-integer value, then the horizontal pixels of the video data are deleted non-linearly according to the first preset rule (that is, the horizontal video resolution of the video data rate for non-linear downscaling adjustments). For example, when the parsed horizontal video resolution is 1920 and the obtained horizontal physical resolution is 1366, then the first ratio N1 is 1920/1366, and the N1 is a non-integer value, then the horizontal pixel points of the video data are calculated according to the first preset ratio. Set rules to delete pixels non-linearly, such as deleting 1920-1366=554 pixels in the horizontal pixels of the video data, the first preset rule can be set according to the actual situation, such as the first preset rule can be It is set to start from the pixel in the middle of the horizontal line of video data, delete a pixel after the first preset number (such as 8), and cycle the first preset number of times (such as 5 times), Then delete a pixel point after the second preset number (such as 5), and cycle the second preset number of times (such as 10 times), and then delete a pixel after the third preset number (such as 3) pixels, and loop the third preset number of times (such as 15 times), etc., wherein the first preset number is greater than the second preset number, the second preset number is greater than the third preset number, and the first The preset number of times is less than the second preset number of times, the second preset number of times is smaller than the third preset number of times, and so on. Preferably, in order to reduce the poor image transition caused by deleting pixels, the RGB colors of the retained pixels can be adjusted accordingly, such as the RGB colors of the retained pixels can be adjusted according to the original RGB colors of the retained pixels. Adjust the RGB colors of the original adjacent two pixels, which is the same as adjusting the RGB colors of the retained pixels in the first case.

The fourth case: if the first ratio N1 is less than 1, and 1/N1 is a non-integer value, then the horizontal pixels of the video data are non-linearly increased according to the second preset rule (that is, the horizontal direction of the video data Non-linear zoom adjustment for video resolution). For example, when the resolved horizontal video resolution is 1366, and the acquired horizontal physical resolution is 1920, then the first ratio N1 is 1366/1920, and the N1 is a non-integer value, then the horizontal pixel points of the video data are calculated according to the second preset ratio. Set the rule to increase pixels non-linearly, such as adding 1920-1366=554 pixels in the horizontal pixels of the video data, the second preset rule can be set according to the actual situation, such as the second preset rule It is set to start from the pixel in the middle of the horizontal row of video data, first add a pixel after the fourth preset number (such as 8), and cycle the fourth preset number of times (such as 5 times), Then add a pixel point after the fifth preset number (such as 5), and cycle the fifth preset number of times (such as 10 times), and then add a pixel after the sixth preset number (such as 3) Pixels, and cycle the sixth preset number of times (such as 15 times), etc., wherein the fourth preset number is greater than the fifth preset number, the fifth preset number is greater than the sixth preset number, and the fourth The preset number of times is smaller than the fifth preset number of times, the fifth preset number of times is smaller than the sixth preset number of times, and so on. The RGB color of the added pixel is determined according to the RGB colors of the two adjacent original pixels on the left and right, which is the same as the RGB color adjustment of the added pixel in the second case.

S23. Analyzing whether the obtained vertical physical resolution is equal to the analyzed vertical video resolution, if not, execute step S24, and if they are equal, execute step S26.

S24. Adjust the vertical video resolution of the video data according to the second ratio N2 between the analyzed vertical video resolution and the obtained vertical physical resolution, so that the vertical video resolution of the video data is consistent with the vertical physical resolution of the display terminal. If the resolutions are equal, then step S25 is performed.

In this step S24, the vertical video resolution of the video data is adjusted according to the second ratio N2 of the analyzed vertical video resolution and the obtained vertical physical resolution, and the adjustment includes the following situations:

The fifth case: if the second ratio N2 is greater than 1, and N2 is an integer value, then delete N2-1 pixels in every N2 vertical pixels of the video data (that is, the vertical video resolution of the video data scaled down). For example, when the parsed vertical video resolution is 1080 and the obtained vertical physical resolution is 540, then the first ratio N1 is 1080/540=2, and one pixel is deleted for every two vertical pixels of the video data point, if the pixels in the vertical column of the video data are B1, B2, B3, B4, B5, B6... B1079, B1080, then one can be deleted from the pixel points in pairs The first pixel in a group, or delete the second pixel in a pairwise group), such as deleting pixels B2, B4, B6...B1080, that is, deleting the pixels of even items, and finally retaining the odd items pixels, the vertical video resolution of the adjusted video data is 540, which is the same as the acquired vertical physical resolution. Preferably, in order to reduce the poor image transition caused by deleting pixels, the RGB colors of the retained pixels can be adjusted accordingly, such as the RGB colors of the retained pixels can be adjusted according to the original RGB colors of the retained pixels. Adjust the RGB colors of the original adjacent two pixels, which is the same as adjusting the RGB colors of the retained pixels in the first case.

The sixth case: if the second ratio N2 is less than 1, and 1/N2 is an integer value, then add 1/N2-1 pixels after each vertical pixel of the video data (that is, for the vertical direction of the video data The video resolution is scaled up and adjusted). For example, when the resolved vertical video resolution is 540 and the obtained vertical physical resolution is 1080, then the second ratio N2 is 540/1080=1/2, and 1/N2 is 2, then in each vertical direction of the video data Add 1 pixel after the pixel. If the pixels in the vertical column of the video data are B1, B2, B3, B4, B5, B6...B539, B540, then the pixels in B1, B3, B5, B7 Add pixels B1', B3', B5', B7'...B539' after ...B539 respectively, then the vertical video resolution of the adjusted video data is 1080, which is the same as the acquired vertical physical resolution. The RGB color of the added pixel is determined according to the RGB colors of the two adjacent original pixels on the left and right, which is the same as the RGB color adjustment of the added pixel in the second case.

The seventh case: if the second ratio N2 is greater than 1, and N2 is a non-integer value, then in the vertical pixels of the video data, the pixels are non-linearly deleted according to the third preset rule (that is, for the vertical video of the video data resolution is non-linearly scaled down). For example, when the resolved vertical video resolution is 1080 and the obtained vertical physical resolution is 768, then the second ratio N2 is 1080/768, and the N2 is a non-integer value. Set the rule to delete pixels non-linearly. For example, 1080-768=312 pixels can be deleted in the vertical pixels of the video data. The third preset rule can be set according to the actual situation. For example, the third preset rule can be Set to start from the pixel in the middle of the vertical column of video data, delete a pixel after the seventh preset number (such as 8), and cycle the seventh preset number of times (such as 5 times), Then delete a pixel after an interval of the eighth preset number (such as 5), and cycle the eighth preset number of times (such as 10 times), and then delete a pixel after an interval of the ninth preset number (such as 3) Pixels, and cycle the ninth preset number of times (such as 15 times), etc., wherein the seventh preset number is greater than the eighth preset number, the eighth preset number is greater than the ninth preset number, and the seventh The preset number of times is less than the eighth preset number of times, the eighth preset number of times is smaller than the ninth preset number of times, and so on. Preferably, in order to reduce the poor image transition caused by deleting pixels, the RGB colors of the retained pixels can be adjusted accordingly, such as the RGB colors of the retained pixels can be adjusted according to the original RGB colors of the retained pixels.
