Problems solved by technology

[0002] At present, for remote teaching, two private line broadband are generally used, one receiving and one sending.
In addition, due to the different formats and supported protocols among audio and video capture devices, servers and video players, data transmission obstacles are caused
During the video playback process, because the video code rate is usually relatively high, and the broadband requirements cannot be matched, it will cause the video playback to freeze and be unclear.

Embodiment 1

[0043] figure 1 It is a schematic diagram of a recording and broadcasting device provided in Embodiment 1 of the present invention.

[0044] refer to figure 1 and figure 2 , the recording and broadcasting device 100 includes: a tracking device 110 , a recording and broadcasting host 120 and an interactive terminal 130 connected in sequence.

[0045] The tracking device 110 is used to collect the first audio and video information of the teaching environment;

[0046] The recording and broadcasting host 120 is used for packaging the first audio and video information, generating second audio information, and storing and publishing the second audio information;

[0047] The interactive terminal 130 is configured to process the first audio and video information at a low bit rate, generate third audio and video information, and transmit the third audio and video information through the network through the protocol push library.

Embodiment 2

[0049] image 3 It is a schematic diagram of the remote teaching equipment provided by Embodiment 2 of the present invention.

[0050] refer to image 3 and Figure 4 , the remote teaching equipment includes a streaming media server 200 and a playback terminal, and also includes the above-mentioned recording and broadcasting device 100; the playback terminal and the interactive terminal 130 of the recording and broadcasting device 100 are respectively connected to the streaming media server 200 through the network.

[0051] The streaming media server 200 is used to process the third audio and video information through the transcoding tool library to generate audio and video playback information;

[0052] The playback terminal is used to request and play audio and video playback information.

Embodiment 3

[0054]The streaming media cloud platform includes three parts: the streaming media server 200 RerunServer, the first management server RerunAS and the second management server RerunNS.

[0055] The streaming media server 200RerunServer is the streaming media service part of the streaming media cloud platform and the core service of the entire streaming media cloud platform. The streaming media server 200RerunServer supports standard RTSP / RTP / RTCP protocols, has RTSP live broadcast function, and is suitable for various terminal platforms such as PC, Android, and IOS live broadcasting; the streaming media server 200RerunServer itself provides a high-performance server-side framework.

[0056] The streaming server 200 processes the third audio and video information through the transcoding tool library to generate audio and video playback information. The transcoding tool library here may be the first tool library RerunAAC and the second tool library RerunAD. The first tool libra...

Abstract

The invention provides recording and broadcasting equipment and remote teaching equipment and relates to the technical field of remote teaching. The remote teaching equipment comprises the recording and broadcasting equipment, a streaming media server and a play terminal. The play terminal and an interaction terminal of the recording and broadcasting equipment are connected with the streaming media server through a network. Tracking equipment is used for collecting first audio / video information of teaching environment; a recording and broadcasting host is used for carrying out packaging processing on the first audio / video information to generate second audio / video information, and storing and releasing the second audio / video information; the interaction terminal is used for carrying out low-code-stream processing on the first audio / video information to generate third audio / video information, and carrying out network transmission on the third audio / video information through a protocol push library; the streaming media server carries out processing on the third audio / video information through a transcoding tool library to generate audio / video play information; and the play terminal requests and plays the audio / video play information. The recording and broadcasting equipment and the remote teaching equipment can reduce transmission requirement and cost and improve video play smoothness.

Description

technical field [0001] The invention relates to the technical field of distance teaching, in particular to recording and broadcasting equipment and distance teaching equipment. Background technique [0002] At present, for distance teaching, two private line broadband is generally used, one receiving and one sending. In addition, due to the different formats and supported protocols among audio and video capture devices, servers and video players, data transmission obstacles are caused. During the video playback process, because the video bit rate is usually relatively high, and the broadband requirements cannot be matched, it will cause the video to freeze and be unclear. Contents of the invention [0003] In view of this, the object of the present invention is to provide recording and broadcasting equipment and distance teaching equipment, so as to reduce transmission requirements and costs, and improve the fluency of video playback. [0004] In the first aspect, an emb...
