Video codec method

Abstract

The present invention discloses a video encoding and decoding method, which includes defining the coordinates of the first vertex and the second vertex of the judgment area in the first reference frame of multiple reference frames of the video, and determining the coordinates of the judgment area in the first reference frame At least one part is extracted and the coordinates of the first and second vertices of the judgment area are determined by the motion vector of the extracted part in other reference frames, and the adjacent two vertices are used in the frame between two adjacent reference frames The judgment area of ​​the reference frame is linearly interpolated to determine the coordinates of the first and second vertices of the judgment area, and the judgment area is displayed according to the coordinates of the first and second vertices when the video is played and in response to the user's decision within the judgment area. The action is selected to display still pictures matching the determined region and associated URL information. This method helps to establish an interactive area for the user while playing a video in an efficient and fast manner.

Description

technical field [0001] The present disclosure relates to the field of human-computer interaction, and more specifically, relates to a video encoding and decoding method used for shopping videos while watching videos. Background technique [0002] At present, online shopping through the Internet, especially the mobile Internet, is already a very common phenomenon. In online shopping, commodities are generally advertised on special shopping websites through advertisements combining pictures and text, and users need to use keywords, etc. on the shopping website. Search online to find items of interest. If the user is interested in purchasing a specific item in the video while watching movies, TV series, live broadcasts, variety shows, etc., he must first search to determine the name and model of the item, which will take extra time for the user. Cause the user to potentially abort the purchase. At present, most videos can only allow users to directly enter the purchase link f...

Problems solved by technology

If the user is interested in purchasing a specific item in the video while watching movies, TV series, live broadcasts, variety shows, etc., he must first search to determine the name and model of the item, which will take extra time for the user. cause the user to potentially abort the purchase

At present, most videos can only allow users to directly enter the purchase link from the video through pre-advertising or pause the insertion of advertisements. Such advertisements have no interaction with the video content, which affects user experience and also makes purchase conversion rate less than ideal

[0003] Especially nowadays, there are many activities for product promotion through live broadcast. Obviously, there is not enough time to manually arrange the video content in the live broadcast to accurately delineate the interaction area for each product. It is difficult to perform complex video editing operations for simple user terminals to send. Using traditional image recognition algorithms to select interactive areas in videos is not only not allowed in terms of operating time and hardware resources, but also poses a challenge to the direct interaction between viewers and videos.
