This application relates to the field of video rebroadcast image processing, and in particular to a method, system and storage medium for replacing advertisements in the process of video rebroadcasting.

Background technique

At present, LED display screens have gradually become necessary supporting facilities for modern sports venues. In some major sports events, especially global sports events, they are usually broadcast simultaneously by many different countries and different TV stations. If it’s just a real-time broadcast of live images, then the sponsor’s advertisements that viewers from different countries and different TV stations can watch can only be the same as the ones displayed on-site. Obviously, sponsors only need to negotiate cooperation with the competition organizing committee. There is no need to cooperate with the TV station. On the one hand, the income of the TV station is reduced, and the value of the broadcast rights of the event will be reduced accordingly. On the other hand, the limited number of LED screens in the stadium also means that the global advertising is limited and the sponsorship is increased. Investment. If the TV station can replace the advertisements displayed on the LED display during the broadcasting process, then each broadcasting TV station will have the right to sell sponsors, increasing the TV station’s income and indirectly increasing the number of advertising spaces, which reduces The investment of a single sponsor has increased the value of the broadcast rights of the event.

Embodiments of the invention

In order to be able to understand the above objectives, features and advantages of the application more clearly, the application will be described in detail below with reference to the accompanying drawings and specific implementations. It should be noted that the embodiments of the application and the features in the embodiments can be combined with each other if there is no conflict.

In the following description, many specific details are set forth in order to fully understand the application, and the described implementations are only a part of the implementations of the application, rather than all of the implementations. Based on the implementation manners in this application, all other implementation manners obtained by those of ordinary skill in the art without creative work fall within the protection scope of this application.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of this application. The terminology used in the specification of the application herein is only for the purpose of describing specific embodiments, and is not intended to limit the application.

The advertisement replacement method in the video rebroadcasting process of the embodiments of the present application can adjust the shutter opening time of the rebroadcast cameras of different TV stations, so that the rebroadcast cameras of different TV stations open the shutter at different times, so that different TV stations can capture different advertisements. The video, through the adjustment of the display duration, completes the rebroadcast, so that the viewers of each TV station can watch the advertisements that are different from the advertisements displayed on the spot, that is, indirectly realize the replacement of advertisements in the process of rebroadcasting.

The following describes in detail the advertisement replacement method in the video rebroadcasting process of each embodiment of the present application with reference to the accompanying drawings.

Please refer to FIG. 1, which exemplarily shows a schematic flowchart of an advertisement replacement method in a video rebroadcasting process of an embodiment of the present application. As shown in Fig. 1, the advertisement replacement method in a video rebroadcasting process includes the following steps:

S110: Periodically insert replacement advertisement frames in the live display advertisement frames;

A dynamic video is composed of multiple continuously displayed frames. When the images of the continuously displayed frames switch fast enough, it can generally be considered that the video is composed. Generally, as long as the number of frames displayed in one second is more than 24, it is difficult for the naked eye to distinguish static frames. Therefore, if there are enough frames continuously displayed in one second, even if one or more different advertising frames are mixed into it, it will not affect the viewer's viewing effect.

The advertisement displayed on the LED display of the stadium includes multiple consecutive live display advertisement frames. Based on the above principle, if one or more frames are inserted between the live display advertisement frames to replace the advertisement frame, the advertisement frame and the replacement advertisement are displayed on the spot. The frame switching speed is fast enough that the replacement advertisement frame cannot be observed with the naked eye. Therefore, for the live audience, what they watch is still an advertisement video composed of continuous live display advertisement frames.

Please continue to refer to Figure 2. Define frame A as the live display advertisement frame, and frame B as the replacement advertisement frame. Assuming that 100 frames are displayed in one second, insert a replacement advertisement frame in every 4 frames of the live display advertisement frame, in order to facilitate the replacement of advertisements For frame capture, the replacement advertisement frame is inserted into the same position in the 4 on-site display advertisement frames in one cycle. Of course, the insertion of the above-mentioned replacement advertisement frames is only exemplary. According to specific rebroadcasting requirements, the positions of the advertisement frames inserted by each TV station may be the same or different. Different inserted frames correspond to the replacement advertisement frames of different TV stations. For example, the replacement advertisement frame corresponding to TV station B is inserted between the first frame and the second frame, and the replacement advertisement frame of TV station C can be inserted between the second frame and the third frame, or it can be inserted between the first frame and the second frame. between.

It can be understood that when the number of frames displayed on the LED display screen is large enough in one second, it can meet the broadcasting needs of multiple TV stations. Each TV station corresponds to different replacement advertisement frames, and the insertion positions of the replacement advertisement frames corresponding to each TV station are different, and Within a period (such as 0.05 seconds or 5 frames in the foregoing embodiment), the insertion position of the replacement advertisement frame corresponding to each TV station is fixed.

It can be understood that the insertion of the replacement advertisement frame can be completed in advance, and the on-site display advertisement inserted with the replacement advertisement frame is directly input into the control system of the LED display screen, and is displayed by the LED display screen. It can also be carried out in real time by the control system of the LED display. For example, the control system of the LED display includes a video processor. The on-site display advertising frames and replacement advertising frames are divided into multiple channels and input to the video processor. The strategy is inserted into the preset position.

S120: Correct the shutter opening time of the relay camera so that the shutter opening time of the relay camera corresponds to the display time of the replacement advertisement frame;

Since the screen displayed on the LED display includes live display advertisement frames and replacement advertisement frames from multiple TV stations, the replacement advertisement frames of each TV station can be the same or different. If the shutter of the rebroadcast camera is always open during the broadcast of the event, the rebroadcast camera In the rebroadcast screen, most of the screen LED display still displays the live display advertising frame, and the switching rate is fast enough. At this time, the LED display in the rebroadcast screen displays the live display advertising frame. Therefore, in order to obtain the To replace the advertising frame of the TV station, the relay camera needs to perform shutter correction before rebroadcasting to adjust the shutter opening time of the rebroadcast camera, so that when the rebroadcast camera opens the shutter, the LED display screen just displays the corresponding TV station’s corresponding Replace the ad frame.

Take the embodiment shown in Figure 2 as an example, insert a replacement advertisement frame in every 4 frames of live display advertisement frames. The replacement advertisement frame is an advertisement frame corresponding to the same TV station, and is placed on the second of every 5 frames. Insert the replacement ad frame at the frame position. At this time, you can adjust the shutter so that the shutter has a cycle of 5 frames (0.0025 seconds). When the second frame is displayed, you can open the shutter to capture the replacement advertising frame required by your own TV station. It can be understood that the opening time of the shutter may be less than the display duration of the replacement advertisement frame, as long as it is ensured that the relay camera can capture the replacement advertisement frame. For example, in the embodiment shown in FIG. 2, the opening time of the shutter can be less than 0.0005s, as long as the shutter is opened within the display time of the second frame.

S130: Adjust the display duration of the rebroadcast video frame captured by the rebroadcast camera;

When the shutter of the rebroadcast camera is opened, a frame is captured. As the shutter is continuously opened, the multiple frames captured by the rebroadcast camera constitute the rebroadcast video. However, if the rebroadcast video frame captured by the rebroadcast camera is directly rebroadcasted out, because each frame The duration of the live broadcast is only 0.0005 seconds. During the live broadcast, because the actual duration of the action on the scene is inconsistent with the shutter opening duration of the rebroadcast camera, a black screen appears when the shutter is closed, resulting in a noticeable pause in the picture. Corresponding to the displayed picture, the display duration of the rebroadcast video frame needs to be adjusted so that the display duration of the rebroadcast video frame is equal to all the frames between the replacement advertisement frame corresponding to the rebroadcast video frame and the replacement advertisement frame corresponding to the next rebroadcast video frame The number shows the sum of time. For example, when the insertion of each replacement advertisement frame is periodic, the display duration of the rebroadcast video frame is adjusted to be equal to the duration of the replacement period corresponding to each replacement advertisement frame. For example, in the embodiment shown in FIG. 2, the display duration of the rebroadcast video frame is adjusted to display 0.0025s.

After adjusting the display duration of the rebroadcast video frame to the duration of the replacement period corresponding to each replacement advertisement frame, the display duration of the rebroadcast video frame in a shutter period can cover the time when the shutter is closed, so that simultaneous rebroadcasting can be achieved without When a black screen appears, there will be no screen freeze.

S140: Rebroadcast the rebroadcast video frame to the display device.

After adjusting the display duration of the rebroadcast video frame, the rebroadcast video frame can be sent out so that the rebroadcast video frame can be displayed on a display device such as a TV to complete the rebroadcast of the screen. At this time, the advertisement displayed on the LED display on the display device The advertisement displayed on the LED display screen will be different from that on the live audience.

Referring to FIG. 3, in one or more embodiments, before step S110, the following steps may be further included:

S101: Perform brightness reduction processing on the replacement advertisement frame.

The higher the brightness of the screen display, the easier it is to be captured by the naked eye. Therefore, the replacement advertisement frame can be reduced in brightness to further reduce the probability of the replacement advertisement frame being captured by the audience.

Referring to FIG. 4, in one or more embodiments, step S110 may specifically include:

S111: Receive a live display advertisement frame and a replacement advertisement frame, and insert the replacement advertisement frame into a plurality of preset positions of the live display advertisement frame;

S113: Adjust the display duration ratio of the on-site display advertisement frame and the replacement advertisement frame.

According to the visual effect, the longer the display time of a frame is, the easier it is to be captured by the naked eye. Conversely, the shorter the display time, the less likely it is to be captured. Therefore, by making the display duration of the replacement advertisement frame shorter than the display duration of the live display advertisement frame, when the display duration ratio of the two reaches an appropriate value, it is more conducive to hiding the replacement advertisement frame.

In a specific embodiment, the adjustment of the display duration ratio between the live display advertisement frame and the replacement advertisement frame can be completed by the video processor. For example, the replacement advertisement frame is inserted between every 2 live display advertisement frames. Receive 1 frame of live display advertisement frame and 1 frame of replacement advertisement frame at a time, insert the replacement advertisement frame into the front or back end of the live display advertisement frame, and then adjust the display time of the replacement advertisement frame, or adjust the live display advertisement frame and replacement advertisement at the same time The display duration of the frame is such that the ratio of the display duration of the live display advertisement frame and the replacement advertisement frame is maintained at a preset value.

Referring to FIG. 5, in one or more embodiments, step S111: receiving live display advertisement frames and replacement advertisement frames, and inserting the replacement advertisement frames into preset positions of multiple live display advertisement frames, which may specifically include:

S1111: Receive the on-site display advertising frame, and perform frequency multiplication processing on the on-site display advertising frame to obtain a two-frame frequency multiplication on-site display advertising frame;

S1113: Receive a replacement advertisement frame, and perform color inversion processing on the replacement advertisement frame to obtain a replacement advertisement frame and a reverse color replacement advertisement frame;

S1115: Insert the replacement advertisement frame and the reverse color replacement advertisement frame into the preset positions of the on-site display advertisement frame after the two-frame frequency multiplication.

Exemplarily, please refer to Figure 6. The video source sends the live display advertisement frame C to the video processor at a frequency of 50 Hz. After the frequency multiplication process, two live display advertisement frames C1 with a frequency of 100 Hz are formed, which will replace the advertisement frame D1. The reverse color replacement advertisement frame D2 can be inserted into the preset position of the on-site display advertising frame C1 after the two-frame frequency multiplication. In the subsequent step S113, the replacement advertisement frame D1, the reverse color replacement advertisement frame D2, and two Adjust the display duration of the on-site display advertising frame C1 after the frame multiplication, so that the combined frame composed of the replacement advertising frame D1, the reverse color replacement advertising frame D2, and the two-frame multiplication on-site display advertising frame C1 outwards at a frequency of 50 Hz send.

After the replacement advertisement frame is inverted, it is equivalent to inserting the replacement advertisement frame and the inverted replacement advertisement frame. After the inversion processing, when the inverted replacement advertisement frame and the replacement advertisement frame overlap the pixels at the same position, The pixel is displayed in white. Therefore, when alternately displayed, the inverted replacement advertisement frame can block the replacement advertisement frame to prevent the color of the replacement advertisement frame from being captured by the audience, which greatly improves the concealment of the replacement advertisement frame.

It should be pointed out that the rebroadcast camera only opens the shutter when displaying the replacement advertisement frame, and the shutter is closed when the reverse color replacement advertisement frame is displayed. In other words, the rebroadcast camera only captures the replacement advertisement frame, not the reverse color replacement advertisement frame. In order to avoid the alternate display of the replacement advertisement frame and the reverse color replacement advertisement frame, due to the residual effect of the pixel display color, the overlapping display is indirectly realized, and the entire frame is white.

In step S1115, the replacement advertisement frame, the reverse color replacement advertisement frame, and the two-frame on-site display advertisement frame can be arranged in any permutation and combination form, but the permutation and combination manners of each replacement period are the same.

Referring to Fig. 2, in one or more embodiments, step S113: adjusting the ratio of the display duration of the on-site display advertisement frame and the replacement advertisement frame, which may specifically be:

Adjust the ratio of the display duration of the live display advertisement frame and the replacement advertisement frame to a preset value, and make the sum of the display duration of the live display advertisement frame and the replacement advertisement frame equal to the display duration of the live display advertisement frame before adjustment.

By making the sum of the display duration of the live display advertisement frame and the replacement advertisement frame equal to the display duration of the live display advertisement frame before adjustment, the video processor can receive the live display advertisement frame according to the same splicing and send it out at the same frequency. Adjusted display ad frame and replacement ad frame.

Referring to FIG. 6, in a specific embodiment, step S113: adjust the ratio of the display duration of the live display advertisement frame and the replacement advertisement frame, which is specifically

The sum of the display duration of the replacement advertisement frame, the reverse color replacement advertisement frame, and the on-site display advertisement frame after two-frame multiplication is adjusted to be equal to the display duration of the on-site display advertisement frame before the multiplication.

In step S1111, after the on-site display video is frequency-multiplied, the frequency of the obtained two-frame on-site display advertisement frame is 100 Hz, and the replacement advertisement frame is inserted according to the preset arrangement and combination with the replacement advertisement frame and the reverse color replacement advertisement frame. , Adjust the frequency of the replacement advertisement frame, the reverse color replacement advertisement frame and the two-frame live display advertisement frame respectively, so that the frequency of the combined frame formed by the replacement advertisement frame, the reverse color replacement advertisement frame and the live display advertisement frame after the two-frame frequency multiplication Maintained at 50Hz, the video processor sends the combined frame to the LED display at a frequency of 50Hz. It can be understood that the merged frame is a virtual frame. When the video frame is sent, the merged frame is not sent to the display device as an actual frame, but is still sent out in a certain order and frequency to replace the advertisement frame D1. The color replacement advertisement frame D2 and the frequency multiplied live display advertisement frame C1, the replacement advertisement frame D1, the reverse color replacement advertisement frame D2, and the two-frame frequency multiplied live display advertisement frame C1 share a frequency of 50 Hz.

It can be understood that the adjustment of the display duration can be achieved by adjusting the sending frequency of the video frame.

The advertisement replacement method in the video rebroadcasting process of the foregoing embodiments adjusts the shutter opening time of the rebroadcast cameras of different TV stations so that the rebroadcast cameras of different TV stations open the shutters at different times, so that different TV stations can capture different advertisement videos. Then through the adjustment of the display duration, the rebroadcast is completed, that is, the replacement of advertisements is indirectly realized in the process of TV rebroadcasting.
