Video interaction method

Abstract

The invention provides a video interaction method. The video interaction method includes the steps: buffering videos to be watched by a user to a first buffer cache and a second buffer cache; collecting the interaction content of the videos to be watched; obtaining each video frame of the videos in the first buffer cache, and extracting an I frame in each video frame; associating the last frame sequence of the video frame with a small window; utilizing the small window and an interaction interface to screen the interaction content matched with the I frame image, and associating the interaction content with the I frame image; and displaying. The video interaction method can perform positioning locking interaction for one video frame in the video; and audiences can select the video frames requiring interaction, according to the own will. The video interaction method is accurate in positioning, and does not have the defect that the interaction contents appear on the whole screen. The video interaction method also can solve the problem of influencing the watching effect of the video frame by the interaction content of the previous video frame when the next video appears.

Description

technical field [0001] The invention relates to the field of video on demand, in particular to a video interaction method. Background technique [0002] A video is composed of multiple video frames, and each video frame includes: [0003] I frame: It is a full-frame compression coded frame, also called an intra-frame coded frame, so the data volume of an I frame is generally relatively large, and the I frame does not need to be generated by referring to other frames. It is a reference frame of a P frame or a B frame. A complete image can be reconstructed by only using I frames during decoding. [0004] P frame: It is a forward predictive coding frame, also known as an inter-frame coding frame. The P frame needs to be generated by referring to the previous I frame or P frame adjacent to it, and it is also the reference frame of other P frames or B frames. When decoding, it must rely on the previous I frame or P frame to reconstruct a complete image. [0005] B frame: It is...

Problems solved by technology

[0006] In order to improve the participation and fun when watching videos, there are video interactions such as voting and comments. Now many TV programs and movie theaters have video interaction functions. Viewers will comment on people, things, things, etc. that appear in the video , and display it on the video, such as what is often called "bullet screen" video, is to float the audience's comments from the video content, but the current technical problems are: the quality of the interactive content cannot be controlled, and the interactive content appears densely. Affect viewing effects, etc. In order to solve the above technical problems, CN102129346 discloses a video interaction method, and CN105357586 discloses a video barrage filtering method and device. The interaction method disclosed above preliminarily solves the problem of poor quality of video interaction content , but the above method is only a simple switch between whether it is interactive or not, and it cannot position and lock each video frame in the video and requires interaction.
