Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The invention provides a method for creating a vertical screen video library, and referring to fig. 1, fig. 1 is a flow chart of a first embodiment of the method for creating a vertical screen video library.
The embodiments of the present invention provide embodiments of a method of creating a vertical screen video library, it should be noted that although a logical order is shown in the flowchart, the steps shown or described may be accomplished in an order different from that shown or described herein under certain data.
The method for creating the vertical screen video library comprises the following steps:
step S10, acquiring a transmission video, and acquiring a horizontal pixel value of a display device and a horizontal pixel value of each transmission video.
The display device acquires the transmission video of which the transmission unit time is less than or equal to the preset transmission time in the network according to the preset transmission time in the display device, acquires the horizontal pixel value of each transmission video according to the video information of the transmission video after the transmission video is acquired, and acquires the horizontal pixel value of the display device according to the device information of the display device.
The display device can be an intelligent television or a personal computer. The preset transfer time is set in the display device in advance according to the need, and the present embodiment is not limited. Networks include, but are not limited to, WIFI (Wireless Fidelity, wireless local area network), routers, and bluetooth. Terminal devices include, but are not limited to, cell phones, tablet computers, and notebook computers. Video information includes horizontal pixel values, vertical pixel values, video quality, and the like of the transmitted video. Display devices include, but are not limited to, smart televisions and personal computers. The device information includes a horizontal pixel value, a vertical pixel value, power consumption information, and the like of the display device.
It should be noted that, the acquired transmission video may be uploaded by the terminal device in real time, or may be stored in the network, which is not limited in this embodiment.
In this embodiment, for example, the preset transmission time is 30 seconds, and the display device acquires the transmission video with the transmission time of less than or equal to 30 seconds in the network.
It should be noted that the horizontal pixel value may be replaced by a vertical pixel value, which is not limited in this embodiment.
Further, the display device acquires vertical pixel values of the respective transmission videos according to the video information of the transmission videos, and acquires vertical pixel values of the display device according to the device information of the display device.
And step S20, obtaining the pixel ratio corresponding to each transmission video according to the horizontal pixel value of the display device and the horizontal pixel value of each transmission video.
After the display device obtains the horizontal pixel value of the display device and the horizontal pixel value of each transmitted video, the horizontal pixel value of the display device and the horizontal pixel value of each transmitted video are calculated through a preset formula, and the pixel ratio of the horizontal pixel value between the display device and each transmitted video is obtained.
Further, the preset formula may be the horizontal pixel value of each transmitted video divided by the horizontal pixel value of the display device, or may be the horizontal pixel value of the display device divided by the horizontal pixel value of each transmitted video.
Further, the step S20 includes:
and a step a of dividing the horizontal pixel value of the display device by the horizontal pixel value of each transmission video to obtain the corresponding pixel ratio of each transmission video.
Specifically, the display device divides the horizontal pixel value of the display device by the horizontal pixel value of each transmitted video to obtain a quotient of the horizontal pixel value between the display device and the transmitted video, wherein the quotient is the pixel ratio of the horizontal pixel value of the display device to the horizontal pixel value of the transmitted video.
In this embodiment, for example, the horizontal pixel value of the display device is 4K, the horizontal pixel value of the transmission video 1 is 2K, the horizontal pixel value of the transmission video 2 is 8K, the display device calculates the pixel ratio of the transmission video 1 to be 2, and the pixel ratio of the transmission video 2 to be 0.5.
And step S30, adjusting each transmission video according to the pixel ratio to obtain an adjusted transmission video, and storing the adjusted transmission video into a vertical screen video library to create the vertical screen video library.
After the display equipment obtains the pixel ratio of each transmission video, the duty ratio or/and the position of each transmission video relative to the display equipment are adjusted according to the size of the pixel ratio, the adjusted transmission video is obtained, then the adjusted transmission video is stored in a vertical screen video library of the display equipment, and the vertical screen video library of the transmission video is created.
Further, the step S30 includes:
step b, acquiring a first center position of the display equipment, and detecting whether the pixel ratio is larger than a preset ratio;
step c, if the pixel ratio is detected to be larger than the preset ratio, acquiring a second center position of the transmitted video, and adjusting the transmitted video according to the first center position and the second center position;
and d, if the pixel ratio is detected to be smaller than or equal to the preset ratio, reducing the horizontal pixel value and the vertical pixel value of the transmission video by half, acquiring a third central position of the reduced transmission video, and adjusting the reduced transmission video according to the third central position and the first central position.
Specifically, after the display device obtains the pixel ratio, a first central position of the display device is obtained, whether the pixel ratio is larger than a preset ratio is detected, if the pixel ratio is detected to be larger than the preset ratio, the display device keeps a horizontal pixel value and a vertical pixel value of a transmission video corresponding to the pixel ratio unchanged, then a second central position corresponding to the transmission video is obtained, then the second central position is adjusted to be in a state of being overlapped with the first central position, and namely the transmission video is adjusted to the central position of the display device. If the pixel ratio is detected to be smaller than or equal to the preset ratio, the display device firstly reduces the horizontal pixel value and the vertical pixel value of the transmitted video corresponding to the pixel ratio to half of the original horizontal pixel value and the original vertical pixel value, then obtains a third central position corresponding to the transmitted video, and then adjusts the third central position to be in a state of being overlapped with the first central position, namely adjusts the transmitted video to the central position of the display device.
The central position refers to a central position of the display device or the video transmission, which is calculated by the display device, and the central position may be represented in a coordinate form, which is not limited in this embodiment. The first center position refers to a horizontal center position or a vertical center position of the display device, the second center position refers to a horizontal center position or a vertical center position of the transmitted video, and the third center position refers to a horizontal center position or a vertical center position of the transmitted video after adjustment. The preset ratio is set according to the horizontal pixel value or the vertical pixel value of the display device, and the preset ratios of different display devices are different, which is not limited in this embodiment. The coincidence state refers to the coverage of two positions within a preset error range. The preset error range is set according to the requirement, and the embodiment is not limited.
Further, the step c includes:
step e, calculating a position difference value between the first central position and the second central position, and detecting whether the position difference value is larger than a preset position difference value or not;
and f, if the position difference value is detected to be larger than the preset position difference value, adjusting the position of the transmitted video so that the position difference value corresponding to the adjusted transmitted video is smaller than or equal to the preset position difference value.
Specifically, after the display device obtains the first central position and the second central position, subtracting the coordinate value of the first central position from the coordinate value of the second central position to obtain a coordinate difference value between the first central position and the second central position, namely, a position difference value between the first central position and the second central position, then detecting whether the position difference value is larger than a preset position difference value, and if the position difference value is detected to be larger than the preset position difference value, adjusting the position of the second central position corresponding to the video transmission by the display device according to different adjustment directions, so that the position difference value between the second central position corresponding to the video transmission after adjustment and the first central position is smaller than or equal to the preset position difference value. If the position difference value is detected to be smaller than or equal to the preset position difference value, the display equipment keeps the position of the transmitted video unchanged. Wherein the direction of adjustment may be left, right, up, etc., or with an angular direction adjustment. The preset position difference value is set according to the horizontal pixel value or the vertical pixel value of the display device, and the preset position difference values of different display devices are different, which is not limited in this embodiment.
Further, the coordinate value of the first center position may be subtracted from the coordinate value of the second center position to obtain a coordinate difference between the first center position and the second center position.
In this embodiment, for example, the preset position difference is 5, the first center position of the display device is (50, 25), the second center position of the transmitted video is (40, 25), the display device calculates that the position difference between the first center position and the second center position is 10, which is greater than the preset position difference 5, and the display device adjusts the transmitted video to the right.
According to the embodiment, the vertical screen video library corresponding to the transmission videos is obtained by acquiring the horizontal pixel value of the display device and the horizontal pixel value of each transmission video, calculating the horizontal pixel value of the display device and the horizontal pixel value of each transmission video, and adjusting each transmission video according to the pixel ratio. Therefore, after the transmission video is obtained, the horizontal pixel value of the transmission video and the horizontal pixel value of the display device are calculated to obtain the pixel ratio of the transmission video, the pixel value or/and the duty ratio of each transmission video are adjusted according to the pixel ratio, and the position relation between the center position of each transmission video and the center position of the display device is adjusted to obtain a vertical screen video library, so that the display device can obtain the video from the vertical screen video library for vertical screen display, the automatic creation of the vertical screen video library is realized, and the display device plays the video through the vertical screen video library.

After the display equipment obtains the play video libraries corresponding to the package names, the weight value of each module of the transmission video in each play video library is obtained, then the weight values of all modules of the same transmission video are added to obtain the weight value of the transmission video, after the weight value is obtained, the transmission video is ordered according to the order of the weight values from large to small according to the size of the weight value of the transmission video, and the ordered play video library is obtained.
The packet name is the ID (Identity Document, identification number) of the transmitted video, and each transmitted video corresponds to a packet name. The packet name may be expressed in chinese or english, and the present embodiment is not limited to the packet name.
