Recording and broadcasting equipment-based intelligent teaching information processing device and method

Abstract

The invention relates to a recording and broadcasting equipment-based intelligent teaching information processing device, which comprises a teacher PC (personal computer), recording cameras, image detection cameras, pickup transmitters, an audio processing device and a recording and broadcasting host, wherein the teacher PC, the recording cameras and the image detection cameras are connected with the recording and broadcasting host; the pickup transmitters are connected with the recording and broadcasting host through the audio processing device. The device comprises a tracking host, wherein the teacher PC, the recording cameras and the image detection cameras are connected with the recording and broadcast host through the tracking host. According to the device, teaching information can be automatically marked to form an xml (extensible markup language) file in a teaching process of a teacher by virtue of an AVA intelligent recording and broadcasting system, knowledge points and teaching link information can be synchronously recorded for the retrieval of the teacher and students after a video is recorded, and the rapidly jumping to corresponding time points for viewing by virtue of virtual slice information embedded into a web player and a mobile terminal player is achieved.

Description

technical field [0001] The invention relates to a teaching information processing system, in particular to an intelligent teaching information processing device and method based on recording and broadcasting equipment. Background technique [0002] With the advancement of my country's education informatization process, recording and broadcasting equipment has gradually become a standard configuration of teaching equipment in the construction of school informatization classrooms. With the help of recording and broadcasting equipment, teachers can independently carry out routine teaching process recording. With the improvement of the performance and usability of video technology and the improvement of teachers' information technology literacy, it has gradually become a reality for teachers to use video technology to carry out classroom teaching research. [0003] With the convenience of recording video, how to retrieve teaching information (knowledge points, teaching links) fr...

AI Technical Summary

Problems solved by technology

[0007] 1. After the video recording is completed, these software need special personnel to use the software to complete the annotation of video teaching information, and there is no way to complete automatic annotation

[0008] 2. Most of these softwares are based on the c / s architecture, and you need to use this software to view the results of annotations when viewing teaching information annotations

The well-marked information did not embed the teaching information into the player from the perspective of convenient viewing by the browser. As a result, when the video is shared on social software (forums, QQ or WeChat, etc.), the video can only be shared, but there is no way Share the teaching information contained in the video together, which affects other people's quick browsing of relevant teaching information

[0009] The reasons for the above defects: firstly, the recording and broadcasting equipment on the market can only complete the recording of teaching videos, but ignore the synchronous recording of classroom teaching information (knowledge points, teaching links), so that the videos can be provided for teachers and students when they are on demand after class. More accurate classroom information, in addition, it does not consider how to achieve fast labeling under the b / s framework and view the labeling through the web page
