Problems solved by technology

The audio and video rendering technology of existing web pages is mainly realized through Flash plug-ins or self-developed browser plug-ins. There is a serious coupling problem between them, which is not conducive to the modularization of the program, and also affects the product maintenance cost
[0003] At the same time, with the continuous development of HTML5 technology, mainstream browsers no longer support browser plug-ins, making the audio and video interaction based on browser plug-ins unable to operate normally. In recent years, WebRTC-based live video and interactive solutions have appeared, but The existing overall solutions are not mature enough to meet the existing needs well

Abstract

The present invention provides an audio-video processor, an intelligent teaching device, an intelligent teaching system and a method. The above-mentioned audio-video processor is characterized in that the audio-video processor is used to establish a corresponding relationship between itself and a shared memory created by a virtual camera. A connection with the shared memory; the audio and video processor is further configured to send audio and video data to the shared memory through the connection, and the audio and video data is displayed through the virtual camera. The above-mentioned intelligent teaching device is characterized in that it includes: a business logic unit and a service unit; the service unit includes: a control server and the above-mentioned audio and video processor. In the case that the browser plug-in technology is not supported, the present invention adopts a reliable, low-cost, high-performance technical solution to solve the problem that the original audio and video interaction, live broadcast and on-demand products based on the browser plug-in cannot be used in HTML5-based technology. Problems with normal operation on the browser.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to an audio and video processor, an intelligent teaching device, an intelligent teaching system and a method. Background technique [0002] The key technical point of existing audio-video interaction on browsers based on B / S architecture (such as real-time video conferencing, live video, on-demand, etc.) is how to realize audio and video rendering on Web pages. The audio and video rendering technology of existing web pages is mainly realized through Flash plug-ins or self-developed browser plug-ins. There is a serious coupling problem between them, which is not conducive to the modularization of the program, and also affects the product maintenance cost. [0003] At the same time, with the continuous development of HTML5 technology, mainstream browsers no longer support browser plug-ins, making the audio and video interaction based on browser plug-ins unable to operate normally...
