Picture, the second video file and the 3rd video file freely change interactive terminal system file, local recorded broadcast by way of click
System 1 can not also specify interactive terminal system 4, and now, 131 instructor in broadcasting's wicket of the first display shows all of remote terminal
The wicket picture of system 3, the first display 131 show current superposition or be not superimposed the 3rd text the 3rd video and superposition or
The first video file of the first text of oneself is not superimposed, and the 3rd display in teleterminal system 3 331 shows superposition
Or the first video file of the first text is not superimposed with, the 3rd audio amplifier 332 plays the first audio file A；When specifying wherein one
When individual teleterminal system 3 is interactive terminal system 4, shows on the second display 431 of interactive terminal system 4 and be superimposed with first
First video file of text, its second audio amplifier 432 play the first audio file B.First video file, the first audio file A,
First audio file B and the first text are still transferred in service, and server 2 respectively correspondingly transmits these files to remote
In journey terminal system 3 and interactive terminal system 4, now the second audio file B of interactive terminal system 4, the second video file and
Into server 2, these file being serviced devices 2 are transmitted to teleterminal system 3 and local recording and broadcasting system 1 second File Transfer
In, and teleterminal system 3 uploads the 3rd video file and the 3rd text of oneself to server 2, server 2 will be all of
3rd video file and the 3rd text are sent to local recording and broadcasting system 1.Local recording and broadcasting system 1 is cut with interactive terminal system 4
Interaction is changed, when other teleterminal system 3 is switched as interactive terminal system 4, this stylish interactive terminal system 4 specified
Start to transmit the second audio file B after echo cancellation to server 2, while also uploaded videos file and text,
And after the interactive model of original interactive terminal system 4 is closed, becoming teleterminal system 3, its audio file B no longer goes up
Server 2 is reached, uploaded videos file and text.
In this embodiment, the first text is shown local first except being optionally added on the first video file
Device 131 shows outer, or optional superposition is aobvious in the first video file that teleterminal system 3, interactive terminal system 4 are downloaded
Show outer.Can be also used for storing with timestamp, video channel opening relationships, therefore finally can be with video and audio video file
Opening relationships, just can get, edits, retrieves and play back positioning ready to the first video file by the first text.Same second
Text and the 3rd text also have same function.
In the present embodiment, have in the broadcasting of the first video file it is various, can with unrestricted choice as image frame, teacher
Record picture or courseware picture in scene.
Advantage of the present utility model is：
1）Simple structure, teleterminal system and interactive terminal system can be interchangeable, and teleterminal system, interaction are eventually
End system and local recording and broadcasting system annexation are simple, and various pieces are made a distinction between the important and the lesser one in running, can listen when interactive
