微格教學(xué)系統(tǒng)中視頻采集與處理技術(shù)研究
[Abstract]:Micro-teaching is widely used in psychology, pedagogy, discipline teaching method, normal education and other fields. It absorbs many advanced teaching ideas and ideas, and plays a very important role in improving the teaching quality, especially the teaching skills of normal students. With the continuous development of modern information technology, especially multimedia technology, it provides a development opportunity for the school to realize the intelligentization of teaching equipment, the modernization of educational management and the diversification of teaching means. This micro-teaching system integrates computer network technology, embedded circuit technology and audio-video technology. It constructs a good platform for effective training of teaching skills, and provides a modern means for teaching process feedback and teaching evaluation. Based on the research of DirectShow streaming media processing platform and H.264/AVC video coding, this paper designs a multi-channel video coding chip SC8919, which integrates H.264 hardware encoder, and designs a multimedia classroom teaching. Multi-channel video recording, storage, transmission, playback functions in one microteaching video processing system. The system can compress the four-channel D1 (720*576@25fps) format image data collected by the camera into a standard H.264 stream in real time, and upload it to the PC of the monitor room (control room and observation room) for storage and decoding. And rely on the existing university Ethernet platform for transmission, no need to lay another dedicated line. The system provides a friendly interface for users to operate and use. Through the actual production and debugging, the technical indicators meet the design requirements. On the basis of analyzing the significance of the selected topic, this paper plans the overall design scheme of the system, including video capture module, PCI data bus interaction module, video server module and network transmission module. Then the H.264/AVC video coding standard and DirectShow streaming media processing platform involved in the design process are described. Secondly, the hardware circuit design of the video capture module based on SC8919 is introduced, and the function and application of the main chip of the module are discussed. Then, the design of video server is introduced. This part of the design is based on the full research and grasp of the use of internal resources of the SC8919 chip, and from the multi-thread design, system initialization design, The detailed design methods of DirectShow filter and system interface are given, and the debugging process of hardware and software is described. Finally, the design process of network transmission module is introduced.
