Introducing ” I want my MTV!
The Internet is great, instead of just TV and newspapers we have a “back channel” – so we are able to “respond” immediately and “interact” in an entire network, It’s like a democratic network, anybody who can connect , may participate.

How can I meet people that I don´t know ?
The idea of “ip based realtime group communication” , beside of amateur radio ,
started 1988 with IRC (internet relay chat ), but there is no video or audio capabilitys, so we are following an older concept calledCU-SeeMe a multiconferencing solution , developed in the early 90’s.

a bit history , what was the problem ?
However; in the past years things changed and all instant messengers using the internet, regardless of their entry method ( jabber and voip applications using SIP or H323, skype and even e-mail) need to know the “adress”, “ID” or Nickname of a “user” to get in contact with him/her. Even then, communication is mostly a one-to-one connection, and does not provide for broad community interaction and NASA NAT broke the rest.
For further understanding the “connectivity” problems, we would suggest reading The Edge Network Management Crisis
But even microsofts desperate attempts to get a foot into the door with Netmeeting , whitch never had multiconferencing abilitys, ended up in a netmeeting porn desaster and gave videoconferencing on the net a bad name.
openCU employs a conference control protocol that has proven to be quite robust and allows for the expression of detailed state regarding the relations of each conference participant to each other participant. In conjunction with a reflector software it allows for customized distribution of conference media, so that nothing is transmitted unless it is used. The protocol is limited in the size of the conference it can serve, but our investigations have shown that this can be extended. The video is encoded in an ad hoc format that was designed for a particular family of desktop machines that were widespread in the past. What it lacks in mathematical elegance, it makes up for in quickness.
Interactive mutimedia streaming
openCU, an de_central opensource cross-platform protocol implementation of opencu. For room based multivideo conferencing up to 70 people (right now ). It currently Supports speex and xvid codecs for video. More specific information soon.How it works
Download openCU ( only XP packages available right now ) and connect . (camera required and port 7648 has to be open), After connecting ,on your left side you will see a list with partizipants . If you klick on a “username” , his video stream will appear in ouropenCU application and on his end , an “eye ” will open and shows that he is been watched and vice versa.
