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.
