Embodiment Construction
[0047] The present invention provides many applicable inventive concepts that can be embodied in numerous specific contexts. The specific examples described in the following embodiments of the present invention are only used as illustrations of specific embodiments of the present invention, and are not intended to limit the scope of the present invention.
[0048] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0049] A transmission method for network teaching, the method comprising:
[0050] An action stream is recorded that includes samples of actions over time. The action flow includes hand-drawn text, hand-drawn graphics, and graphics reserved in software. When recording text, what is recorded is the coordinates of the generated trajectory of the text; when recording graphics, first draw a rectangular frame on the boundary of the graphics through the algorithm module inside the program, and t...

The invention discloses a transmission method and system for network teaching. The method comprises the steps of recording an action stream, recording an audio stream, recording the timestamp information of the action stream and the timestamp information of the audio stream, transmitting the action stream and the audio stream, preferably transmitting the action stream and the audio stream in real time, and carrying out synchronous display on the recorded action stream and the recorded audio stream according to the timestamp information at the position of a terminal. The system comprises an action recorder for recording the action stream, an audio recorder for recording the audio stream, a timer for recording the timestamp information of the action stream and the timestamp information of the audio stream, an emitter for transmitting the action stream and the audio stream and the terminal for carrying out the synchronous display on the recorded action stream and the recorded audio stream according to the timestamp information, and preferably the emitter is used for transmitting the action stream and the audio stream in real time. The transmission method and system for network teaching at least solve the problems of the storage of teaching resources and the transmission of the network of the teaching resources.
Description
technical field [0001] The invention relates to a transmission method, in particular to a transmission method and system for network teaching. Background technique [0002] Due to the scarcity of educational resources, shared learning resources have become the key to solving this problem. With the popularity of the network and the reduction of hardware costs, a basic foundation has been laid for the network education platform. However, resource storage and network transmission have become problems that need to be solved urgently. The video files generated by the existing h.264, flv, rmvb and other encoding methods are not convenient for storage and network transmission because they take up too much space. Taking one hour of video recording as an example, the video file in the traditional format is about 100M. If you want to watch it on a large screen without distortion, you even need to use G. This is unacceptable for existing network and storage device conditions. Cont...
