Embodiment 1
[0038] like figure 1 and image 3 As shown, this embodiment provides a video and audio trusted playback method for generating an associated summary based on intra-frame extraction, including the following steps:
[0039] S1: During the transcoding service process of the video streaming media, the publisher extracts a data segment of a certain length in each video frame of the video segment according to the set intra-frame extraction regular intervals;
[0040] Under normal circumstances, the transcoding service of the video publishing side is to scale, encode and sign the decoded video streaming media successively;
[0041] There are many kinds of intra-frame extraction rules. This embodiment describes three kinds of intra-frame extraction rules. The first one is to select the data bits corresponding to the video frame, that is, the data segment according to the value of the Fibonacci sequence. The combination of odd squares and even numbers selects the data bits of the cor...
