Method and system for recording and playback of web-based instructions

A system for recording and broadcasting network teaching, comprising:

• a processor;
• and
• a computer readable storage medium, having computer readable medium code, when executed, causing the processor to:
• start recording a file;
• create a file identity identifier (ID);
• collect audio data from a first audio source to form a first audio data stream;
• collect audio data from one or more second audio sources to form a second audio data stream;
• collect motion data from a multimedia whiteboard to form a multimedia whiteboard motion data stream;
• collect operation data from at least one screen display to form a screen display operation data stream, the at least one screen display including various application operations on an electronic document displayed on the at least one screen display;
• create a time stamp identity;
• create a set of files by combing and binding the file identity ID and the time stamp identity with the first audio data stream, the second audio data stream, the multimedia whiteboard motion data stream, the screen display operation data stream, and the electronic document;
• store the set of files in a database according to respective formats;
• acquire the first audio data stream, the second audio data stream, the multimedia whiteboard motion data stream, and the screen display operation data stream via internet respectively by a user terminal;
• and
• broadcast recorded content according to time stamp identity with client installed on the user terminal following the acquiring,
• wherein the first audio source is a teacher user of a teaching activity, a first keynote speaker of an online conference, or a first speaker of an interactive communication activity,
• wherein the second audio source is a student user of the teaching activity, a second keynote speaker of the online conference, or a second speaker of the interactive communication activity,
• wherein the terminal is a mobile terminal or a wired fixed computer terminal, and wherein the network is a wireless or a wired local area network or a wide area network.
