RTSP is a network streaming protocol that provides a mechanism for streaming media transmission over IP networks. The RTSP protocol defines the interaction process between the client and server. The client can send control commands to the server, such as play, pause, record, etc., while the server performs corresponding operations based on the client’s commands. Therefore, through the RTSP protocol, we can achieve real-time transmission and recording of video streams.
The recording and playback function of RTSP mainly depends on the storage and playback capabilities of the server. When the client sends a recording request to the server, the server writes the video stream to the local storage device while maintaining real-time transmission of the video stream. After the recording is completed, the client can replay the recorded video stream through the RTSP protocol. Therefore, the recording and playback function of RTSP can achieve real-time recording and playback of video streams.
The BJ66 standard version of the Bijie Multimedia Collaboration System provides an RTSP interface that can be integrated with school recording and broadcasting systems. This function enables the recording and storage of teaching screen projection audio and video. Through integration with the recording system, BJ66 can achieve automated recording without the need for additional manual operation. In this way, whether it is classroom teaching, experimental demonstrations, or other teaching activities, the entire process can be recorded, providing detailed teaching process materials for the school, and valuable materials for subsequent teaching evaluation, teaching reflection, and student review.
The advantages of RTSP recording and playback function
(1) Real time performance: The recording and playback function of RTSP can achieve real-time transmission and recording of video streams, meeting the needs of real-time monitoring.
(2) Scalability: RTSP protocol is a text-based protocol that is easy to extend and modify, and can adapt to different application scenarios and requirements.
(3) Flexibility: The recording and playback function of RTSP can be customized according to actual needs, such as recording duration, resolution, bitrate, etc., to meet the needs of different users.
(4) Cross platform compatibility: The RTSP protocol can be implemented on different operating systems and devices, and has good cross platform compatibility.
