What is the TeleTeachingTool ?
The TeleTeachingTool is a piece of software to record, transmit and replay of multimedia-based lectures, speeches and documentations.Features:
- free software
- platform independent ( Java )
- recording and internet-transmission of ...
- ... computer-desktop with any application ( screen recording based on VNC )
- ... video and audio from the speaker
- multicast- and unicast-transmission
To download the TTT go to the download page. Please note the requirements for using the TeleTeachingTool. On the help page you can get information about the installation and the usage as spectator. If you want to run a server you can find help on the page running a server.
How does the TeleTeachingTool work ?
You can find a lecture about the TeleTeachingTool (german language) which explains the workings of the TeleTeachingTool in the archive of recordings.The TTT transmits (besides video and audio) the whole desktop area of the speaker's computer including all applications. This flexibilty is possible by using the Virtual Network Computing (VNC)-tool, a software used for viewing and remote-controlling a computer-desktop over a network.
To use the TTT, a VNC-server is started on the computer whose desktop should be shown during the presentation (lets call it source-computer from now on). For example this computer could be the office-computer of the speaker. Furthermore a TTT-server has to be started (either on a seperate computer, or even on the same).
During the lecture the speaker uses a computer which runs the TTT in lector-mode (screenshots). This does not only show the desktop of the source-computer on the presentation-computer, but also makes it possible for the speaker to manipulate it and use some basic painting tools to highlight important screen contents (screenshots). By using a beamer which is connected to the presentation-computer, the screen contents can be shown to the audience being present at the lecture hall.
The TTT-server is capable of recording and transmitting everything that is visible on the presentation-computer (namely desktop of the source-computer, manipulations of the same (mouse movement, starting of applications and so on) as well as highlights by the speaker (painting tools)).
Since the desktop of any computer can be shown in the presentaion hall in this way, it is possible for the speaker to do the lecture in a familiar computer-environment including every application he wants to use without having to use e.g his own laptop (screenshots).
To record audio- and video data a video camera and a microphone are used in the lecture hall. These data is transmitted/recorded by the TTT-server, too.
