Abstract

The invention provides an interactive low power consumption live broadcasting and recorded broadcasting system and method for teaching. The student side adopts a special low power consumption interaction terminal, and is provided with a live broadcasting control all-in-one machine; the live broadcasting control all-in-one machine can acquire audio and video streaming media, course and teaching plan pictures or files and attached media file for time axis synchronization, generate a real-time coarse data stream, and upload the real-time coarse data stream to a live broadcasting and recorded broadcasting center server; the live broadcasting control all-in-one machine further acquires the coarse data stream from the live broadcasting and recorded broadcasting center server for demultiplexing, enables the audio and video streaming media and the attached media files to reappear, and pushes the course and teaching plan pictures or files to the low power consumption interaction terminal for synchronous displaying. The system further realizes interaction between interacting contents and interacting messages. The invention provides a two-dimensional time axis synchronization technology based on an intensive timestamp and the content overlap ratio, and synchronous association of the interacting contents, the interacting messages and the real-time coarse data stream is realized.

Description

technical field [0001] The present invention relates to the technical field of teaching live broadcasting and recording and broadcasting, in particular to an interactive low-power teaching live recording and broadcasting system and method. Background technique [0002] With the rapid development of modern network technology and the continuous improvement of video and audio codec technology, Internet-based remote audio and video interactive equipment is rapidly popularized and widely used in teleconferencing and distance teaching. [0003] In distance education, the live broadcast and recording system is generally used to make the teacher's lecture content into multimedia forms including audio and video, and the live broadcast center can record and broadcast the live broadcast, and students can receive and watch the multimedia through the handheld terminal. Such a system is called a teaching live broadcast and recording system. [0004] For example, the Chinese patent applic...
