Video advertising system
A video advertising system, methods, and apparatus are disclosed, which may include an advertising system, including an advertising server and advertising console, and a user device, which may cooperate to select video advertising campaigns and display video advertisements. In an example embodiment, a method includes playing a video on a display, overlaying markings on the video while the video plays, at a first time while the video plays, measuring a first refresh rate of the video, at a second time while the video plays, performing a first operation on the markings, measuring a second refresh rate of the video at the second time, and determining an estimated area of the video displayed on the display based on the first refresh rate and the second refresh rate. In an example embodiment, a prediction model is trained to output a viewability inference for a video.
1. A method comprising:
playing a video on a display of an electronic device, wherein the video has a height and a width, the video has a geometric area based on the height and width;
predicting, using a processor, a portion of the video that is viewable by splitting the video into a plurality of tiles;
invoking, using a device-side advertisement Application Program Interface (API), a browser refresh callback function to issue a callback from a browser to the device-side advertisement API when the browser refreshes the tiles of the video;
at a first time while the video plays on the display, measuring a first refresh rate for each tile of the plurality of tiles of the video using the device-side advertisement API;
overlaying markings, using the device-side advertisement API, on each tile of the plurality of tiles of the video in the geometric area while the video plays;
at a second time while the video plays on the display, performing, by the device-side advertisement API, a first processor-based operation on the markings;
while the video plays on the display at the second time, performing, by the processor, a refreshing operation, and the first processor-based operation slows down the refreshing operation of viewable tiles of the video;
measuring a second refresh rate for each tile of the plurality of tiles of the video at the second time during the refreshing operation wherein the second refresh rate of the viewable tiles of the video is less than the first refresh rate based on the processor performing the first processor-based operation;
predicting, by the device-side advertisement API, whether each tile of plurality tiles is viewable based on the second refresh rate and properties of end user device; and
determining an estimated area of the video displayed on the display based on the first refresh rate and the second refresh rate and number of predicted viewable tiles of the plurality of tiles of the video, wherein the estimated area is indicative of a viewability of the video.
2. The method of claim 1 , further comprising comparing the estimated area of the video displayed on the display to a threshold area.
3. The method of claim 2 , further comprising responsive to the estimated area of the video displayed on the display being less than the threshold area, pausing the video.
4. The method of claim 1 , wherein the first processor-based operation includes blurring, which slows down the refreshing operation of the viewable portion of the video.
5. The method of claim 1 , further comprising:
performing, by the processor, a second processor-based operation on the markings while the video plays; and
measuring a third refresh rate of the video at the third time, wherein the estimated area of the video displayed on the display at the third time is determined based on the first refresh rate, the second refresh rate, and the third refresh rate.
6. The method of claim 5 , further comprising:
comparing the estimated area of the video displayed on the display at the third time to the threshold area; and
responsive to the estimated area of the video displayed on the display being greater than the threshold area, resume playing the video.
7. The method of claim 1 , wherein the markings on the video in the geometric area include at least one of alphanumeric characters and symbols.
8. The method of claim 1 , wherein determining the estimated area of the video displayed on the display includes comparing the first refresh rate to the second refresh rate.
9. The method of claim 1 , wherein the first processor-based operation includes dithering, which slows down the refreshing operation of the viewable portion of the video.
10. The method of claim 1 , wherein the markings are substantially invisible to a user.
11. The method of claim 1 , wherein determining the estimated area of the video displayed on the display is based on a refresh rate slowdown.
12. The method of claim 1 , wherein the first refresh rate is greater than the second refresh rate when at least a first area of the video is displayed on the display.
13. The method of claim 1 , wherein the first refresh rate is measured in frames per second.
14. The method of claim 1 , wherein the second time is at least 100 milliseconds after the first time.
15. The method of claim 1 , wherein the video is played in an inline frame.
16. The method of claim 15 , wherein the video is displayed in native video player.
17. The method of claim 15 , further comprising:
executing a geometric determination of the estimated area of the video displayed in the inline frame.
18. The method of claim 1 , wherein the video is displayed in a viewport, which includes a viewable portion of content that is adjustable through scrolling.
19. The method of claim 18 , wherein the estimated area of the video displayed on the display changes based on a user scrolling at least one of vertically and laterally within the viewport.
