Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application. On the contrary, the embodiments of the application include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.
Fig. 1 is a flowchart illustrating a method for transmitting non-standard resolution data according to an embodiment of the present application.
The present embodiment is exemplified in a case where the transmission method of the non-standard resolution data is configured as a transmission apparatus of the non-standard resolution data.
In this embodiment, the transmission apparatus for non-standard resolution data may be disposed in a server, or may also be disposed in a mobile device, which is not limited in this embodiment of the present application.
The method for transmitting the data with the non-standard resolution ratio in the embodiment of the application is used for configuring the resolution ratio when the electronic equipment transmits the data to be transmitted with the resolution ratio being the non-standard resolution ratio, and transmitting the data to be transmitted according to the configured transmission resolution ratio.
The transmitted data may be used for playback display in a media player.
The electronic device is, for example, a Personal Computer (PC), a cloud device or a mobile device, and the mobile device is, for example, a smart phone or a tablet Computer.
It should be noted that the execution main body in the embodiment of the present application may be, for example, a Central Processing Unit (CPU) in a server or an electronic device in terms of hardware, and may be, for example, a background management service in the server or the electronic device in terms of software, which is not limited to this.
The embodiment of the application is exemplified by that a transmission device of non-standard resolution data is arranged in the mobile equipment.
Referring to fig. 1, the method includes:
s101: and determining a position area in a pixel scale frame to which the non-standard resolution of the data to be transmitted belongs and taking the position area as a target position area.
It is understood that the resolution (resolution) is the precision of the screen image of the electronic device or the server, and refers to how many pixels can be displayed on the display of the electronic device or the server, and is measured by horizontal and vertical pixels. When the screen resolution is low (e.g., 640x 480), fewer pixels are displayed on the screen, but the size is larger. When the screen resolution is high (e.g., 1600x 1200), more pixels are displayed on the screen, but the size is smaller.
Specifically, the resolution is the number of pixels displayed on the screen, and 160 × 128 indicates that 160 pixels are included in the horizontal direction and 128 pixels are included in the vertical direction. Under the condition of the same screen size, the higher the resolution ratio is, the finer and finer the display effect is.
The standard resolution may be, for example, 2160P (4K resolution, i.e., 4096 × 2160 pixel resolution), 1080P (1920 × 1080), 1080I (1920 × 1080), 720P (1280 × 720), 480P (720 × 480), 480I (720 × 480), 576P (720 × 576), 576I (720 × 576), and standard resolutions output by displays of various electronic devices or servers in the related art.
The non-standard resolution in the embodiment of the present application is a resolution other than the standard resolution described above.
In the related art, a media player in an electronic device or a server outputs a resolution as close to a film Source as possible for Source Direct resolution, for the transmission of some non-standard resolution data, the simple one-sided adoption of the method leads the horizontal resolution or the vertical resolution to exceed the standard resolution, the output resolution of the Source Direct resolution mode is automatically determined to be a resolution higher than the standard resolution that is exceeded by one for transmission, e.g., the video resolution of the electronic device is 800x480, the resolution is treated as 1280x720 for transmission, which, in this way, results in the original resolution of the data to be transmitted being subjected to too much stretch-zoom processing, the definition of the image data is reduced, the granular feeling of the pixels is rough and fuzzy, and the display processing effect of the image data is poor.
Therefore, in the embodiment of the application, by determining the position area in the pixel scale frame to which the non-standard resolution of the data to be transmitted belongs and using the position area as the target position area, the transmission resolution is configured according to the configuration rule corresponding to the target position area, and the data to be transmitted is transmitted according to the configured transmission resolution, so that the non-standard resolution is effectively prevented from being excessively stretched, amplified or compressed in the data transmission process of the sub-standard resolution, and the data display definition and the display effect are improved.

The steps are simple and convenient to implement, and technicians can preset required configuration rules according to self requirements or application scenes of actual data transmission, so that the use flexibility of the method is improved, and the individualized scene requirements of data transmission are met.
An example of a configuration rule may be embodied as the following steps, see in conjunction with figures 3 and 4,
1. a standard 1080P (1920x1080) resolution pixel scale frame (1920 pixels horizontally and 1080 pixels vertically) is drawn. Setting: ui2SrcH (horizontal pixel) & & ui2SrcV (vertical pixel) &1080to facilitate calculation and division of subsequent pixel areas.
2. Within a 1920x1080 (standard 1080P resolution) pixel scale framework, dividing into four blocks with 720P (1280x720) as a line, resulting in four first location areas: a first position region C1, a first position region C2, a first position region C3, and a first position region E, wherein the pixel number range of the first position region C2 is specifically set as follows: (ui2SrcH (horizontal pixel) >1280| | | ui2SrcV (vertical pixel) >720), see the division identification symbols of the four first position regions of fig. 3.
3. First position area C1: the upper left corner of a location area may include a right frame, and the range of the number of pixels corresponding to the resolution of the location area is:
ui2SrcH (horizontal pixel) <1280 & & ui2SrcV (vertical pixel) > 720. For example: the non-standard resolution of the data to be transmitted is SrcH (horizontal pixel) 960 and SrcV (vertical pixel) 810, which belong to the first position area C1.
4. The configuration rule is set as: when the nonstandard resolution of the data to be transmitted occupies a pixel area corresponding to the pixel scale and is 1/4, which is larger than or equal to the second pixel area of the first position region C1, as the first pixel area, the nonstandard resolution (horizontal pixels + vertical pixels) is all stretched to (1920x1080), which (1920x1080) may be referred to as the configured transmission resolution; when the first pixel area is less than 1/4 of the second pixel area of the first location area C1, the horizontal pixels are stretched to 1280 and the vertical pixels are compressed to 720.
The specific calculation formula is as follows:
((1280-ui2SrcH)*(ui2SrcV-720)>＝1280*(1080-720)/4)(115200)；
where 115200 is a pixel area value of 1/4 area of the second pixel area of the first position region C1.
For example: (1280-. The non-standard resolution, 960 x 810, stretches horizontal pixels to 1280 and compresses vertical pixels to 720 for processing.
5. First position area C2: a position area at the upper right corner, if the non-standard resolution of the data to be transmitted belongs to the first position area C2, the configuration rule is set as: all the pixels with the non-standard resolution (horizontal pixels + vertical pixels) are stretched to (1920x1080), and whether the horizontal pixels and the vertical pixels with the non-standard resolution belong to the pixel number range of the position area can be judged, and the area of 1/4 is not calculated. The image data display effect can be effectively guaranteed, and meanwhile, the consumption of computing resources is saved.
The pixel number range is: (ui2SrcH (horizontal pixel) >1280& & ui2SrcV (vertical pixel) > 720).
6. First position area C3: the lower right corner of a location area, which may include an upper frame, may have a resolution in the range of the number of pixels:
ui2SrcH (horizontal pixel) >1280& & ui2SrcV (vertical pixel) < ═ 720.
For example: the non-standard resolution of the data to be transmitted is SrcH (horizontal pixel) 1440 and SrcV (vertical pixel) 540, which belong to the first position area C3.
7. The configuration rule is set as: when the nonstandard resolution of the data to be transmitted occupies a pixel area corresponding to the pixel scale and is equal to or larger than 1/4 of a second pixel area of the first position region C3 as the first pixel area, the second position regions E3 (horizontal pixels + vertical pixels) are all stretched to (1920x1080), which (1920x1080) may be referred to as the configured transmission resolution; when the first pixel area is less than 1/4 of the second pixel area of the first location area C3, the horizontal pixels are compressed to 1280 and the vertical pixels are stretched to 720.
The specific calculation formula is as follows:
((ui2SrcH-1280)*(720-ui2SrcV)>＝1280*(1080-720)/4)(115200)；
where, (115200 is a pixel area value of 1/4 area of the second pixel area of the first position region C3.
For example: (1440-1280) (720-540) — 160-180-28800, and the first pixel area is smaller than the 1/4 area 115200 of the second pixel area of the first position area C3. The non-standard resolution 1440 x 540, compressed horizontal pixels to 1280 and stretched vertical pixels to 720 for processing.
8. The pixels in the pixel scale frame are 1280x720 pixel points, that is, four intersected pixel points in the first position area and the standard 720P resolution, and whether the vertex of the upper right corner pixel with the non-standard resolution is exactly 1280x720 pixel points or not can be only judged, and if so, configuration is performed according to the following configuration rules.
The transmission resolution is: (ui2SrcH (horizontal pixel) ═ 1280& & ui2SrcV (vertical pixel): 720).
9. First position area E: inside a 1280 × 720 pixel scale frame, the scale frame is divided into four blocks by taking 720 × 480 or 720 × 576 as lines, and the specific arrangement is as follows: (ui2SrcH (horizontal pixel) >720| | ui2SrcV (vertical pixel) > ui2SdV (480|576)), see the four blocks of the second position region of fig. 3 (shown by the reference numeral 32 in fig. 3, the reference numeral 32 indicates the second position region E1, the second position region E2, the second position region E3, and the second position region F) dividing the identification symbol.
10. Second position area E1: the upper left corner of a location area may include a right frame, and the range of the number of pixels corresponding to the resolution of the location area is:
(ui2SrcH (horizontal pixel) < & & ui2SrcV (vertical pixel) > ui2SdV (480| 576)).
For example: the non-standard resolution of the data to be transmitted is SrcH (horizontal pixel) 540 and SrcV (vertical pixel) 486, which belong to the second position area E1.
11. The configuration rule is set as: when the nonstandard resolution of the data to be transmitted occupies a pixel area corresponding to the pixel scale and is equal to or larger than 1/4 of the second pixel area of the second position area E1 as the first pixel area, both the nonstandard resolution (horizontal pixels + vertical pixels) are stretched to (1280x720), which (1280x720) may be referred to as the configured transmission resolution; when the first pixel area is less than 1/4 of the second pixel area of the second position region E1, the horizontal pixels are stretched to 720 and the vertical pixels are compressed to 576/480.
The specific calculation formula is as follows:
((720-ui2SrcH)*(ui2SrcV480|576)>＝720*(720-480|576)/4)(43200|25920)；
43200 and 25920 are pixel area values of 1/4 areas of the second pixel area of the second position region E1, and the two pixel area values correspond to the division method of 720 × 480 or 720 × 576 respectively.
For example: (720-.
The NTSC format, i.e., the resolution of 480, can be calculated. The 576 resolution calculation mode is the same as 480 resolution, if 576 resolution is calculated as a reference standard, the reference pixel area result is 25920, the 480 resolution is used as a reference in the following calculation, and the 576 resolution calculation is not described again.
12. Second position area E2: a position area at the upper right corner, if the nonstandard resolution of the data to be transmitted belongs to the second position area E2, the configuration rule is set as: all the pixels with the non-standard resolution (horizontal pixel + vertical pixel) are stretched to (1280x720), and whether the horizontal pixel and the vertical pixel with the non-standard resolution belong to the pixel number range of the position area can be judged, and the area does not need to be calculated 1/4 any more. The image data display effect can be effectively guaranteed, and meanwhile, the consumption of computing resources is saved.
The pixel number range is: (ui2SrcH (horizontal pixel) >720& & ui2SrcV (vertical pixel) > ui2SdV (480| 576)).
13. Second position area E3: the lower right corner of a location area, which may include an upper frame, may have a resolution in the range of the number of pixels:
(ui2SrcH (horizontal pixel) >720& & ui2SrcV (vertical pixel) < ═ ui2SdV (480| 576)).
For example: the non-standard resolution of the data to be transmitted is SrcH (horizontal pixel) 810 and SrcV (vertical pixel) 403, and belongs to the second position area E3.
14. The configuration rule is set as: when the nonstandard resolution of the data to be transmitted occupies a pixel area corresponding to the pixel scale and is used as the first pixel area, which is more than or equal to 1/4 of the second pixel area of the second position region E3, the second position regions E3 (horizontal pixels + vertical pixels) are all stretched to (1280x 720); when the first pixel area is less than 1/4 of the second pixel area of the second position region E3, the horizontal pixels are compressed to 720 and the vertical pixels are stretched to 576/480.
The specific calculation formula is as follows:
((ui2SrcH-720)*(480|576-ui2SrcV)>＝720*(720-480|576)/4)(43200|25920)；
43200 and 25920 are pixel area values of 1/4 areas of the second pixel area of the second position region E3, and the two pixel area values correspond to the division method of 720 × 480 or 720 × 576 respectively.
For example: (810-.
15. Second position area F: inside the block 720x480|576, it can be determined only whether the horizontal pixel and the vertical pixel of the non-standard resolution belong to the pixel number range of the position area, and the area of 1/4 is not calculated.
