Problems solved by technology

Therefore, it has the disadvantages of poor experience and the inability to combine teaching and practice in class
[0008] As for the processing scheme that triggers interaction according to the preset video playback time, the timing of the interaction needs to monitor the video playback time, and the playback speed caused by video playback freeze Changes are relatively sensitive, and since all interactions are triggered according to a preset time, it is also impossible to realize external unlimited time live broadcasting of recording and broadcasting resources through streaming media, and the flexibility is poor

Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] see figure 1 , the present invention provides a technical solution: a multimedia recording and broadcasting course interaction method based on video SEI messages. In H.264 decoding, the course interaction information is synchronously encoded into the teaching video through SEI messages. The analysis of the message triggers the interactive module to load the corresponding interactive material to provide the interactive experience in the class.

Abstract

The invention discloses a multimedia recording and broadcasting course interaction method based on a video SEI message, course interaction information is synchronously coded into a teaching video in an SEI message mode in H.264 decoding, and an interaction module is triggered to load a corresponding interaction material to provide interaction experience in a course through analysis of the messageduring course broadcasting. Through the implementation of the technology, organic combination of teaching and practice can be realized, the atmosphere feeling of a recording and broadcasting classroomis enhanced, the attention of students is improved, and finally the teaching effect is improved. Meanwhile, SEI information contained in H.264 coding can be synchronously transmitted in a streaming media mode, accurate synchronization of teaching and interaction of more scenes is achieved, and the recording and broadcasting course form developed on the basis of the technology is not limited to the single form of video watching any more, including streaming media live broadcasting, video free grouping and segmented playing and other forms.

Description

technical field [0001] The invention relates to the technical field of audio and video processing in digital teaching scenes, and more specifically relates to an interactive method for multimedia recording and broadcasting lessons based on video SEI messages. Background technique [0002] In the digital teaching scene, the recording and broadcasting teaching is mainly through the pre-recording and post-processing steps of the teacher's class content to produce a series of teaching video content for a certain field of knowledge, and the students watch the video. A form of teaching to achieve learning. Recorded courses have been widely used in the teaching process of students of various disciplines and age groups due to the characteristics of one-time production and multiple use, low cost of courses, and flexible learning time for students. [0003] At the same time, with the development of digital teaching content, there are more and more digital interactive elements in the ...
