Description

An interactive video advertisement placement method and system

technical field

The present invention relates to the technical field of video processing, and in particular, to a method and system for implanting an interactive video advertisement.

Background technique

With the increasing development of technologies such as computers and the Internet, the application of video content has become increasingly widespread, and various video applications have emerged one after another. In the face of the huge video application market, the way of advertising investment when video content is playing has also emerged as the times require. In the current advertising delivery method when video content is played, the advertising content is usually played between video clips, such as the advertising time of a TV program, between different episodes of a TV series, and two consecutive segments during online video-on-demand. Between video contents, and the played advertisement content is usually a pre-set advertisement content, such as the latest new advertisement, or an advertisement determined based on other selection conditions, and whether the advertisement content is related to the played video I don’t care about the continuity or relevance of the content; and there is a lack of interaction between the advertisement and the anchor, and the appropriate advertisement cannot be displayed according to the actual scene, resulting in a low click-through rate or insignificant effect of the advertisement.

In addition, in the prior art, it is generally adopted to directly replace a specific area in a video image frame with an advertisement object. Since the background shape, brightness, color, texture and other factors are not considered, the shape, brightness, color, texture of the surface of the replaced advertisement object is not considered. and so on are often inconsistent with the area before the replacement, so the replaced advertisement object cannot be well integrated into the video image frame, and is inconsistent with the surrounding area in the video image frame, which affects the user experience effect.
