Embodiment Construction

[0022] Such as figure 1 As shown, the present invention provides a recording method for teaching courseware of a power system, which is characterized by including the following steps:

[0023] S01: Provide a video recorder to record teaching videos and output a teaching video signal;

[0024] S02: Provide a PC to provide a PPT courseware signal and audio signal;

[0025] S03: Provide a switcher to receive the teaching video signal, PPT courseware signal and audio signal, and perform data mixing;

[0026] S04: Provide a recorder and player to receive the signal after the switcher performs data mixing;

[0027] S05: Provide a video workstation to receive the output signal of the VCR and output the required teaching courseware video.

[0028] Preferably, the PPT courseware signal is input to the switcher through a VGA to BNC converter; the teaching video signal is set on the left side of the teaching courseware video, and the PPT courseware signal is set on the teaching courseware The righ...

Description

Technical field [0001] The invention relates to a recording method and system for teaching courseware of a power system, and is particularly suitable for the recording field of teaching courseware of a power system. Background technique [0002] With the rapid development of society today, multimedia courseware has become an increasingly important teaching method, and multimedia courseware recording has become increasingly important. At present, the power system generally adopts the scheme of purchasing courseware recording equipment, and the cost is more than 500,000 yuan, and the video format is single, the compatibility is poor, and later editing is impossible. This article aims to provide a cheap synchronous recording of courseware and PPT, and can record MPG, AVI and other formats according to actual needs for students to learn. Summary of the invention [0003] In view of this, the purpose of the present invention is to provide a recording method and system for teaching cou...
