Jaromil and Eleonora wrote a research about video streaming, commissioned by dutch media institute Montevideo.
It has not been published yet on the net, but Jaromil brought it, and it's licensed under GNU Free Documentation License.
jaromil explains that copy protection is a bad idea, and also a waste of time.
talking about streaming, there are two ways: on-demand and 'programmed' (live).
For programmed streaming, you can use Darwin Streaming Server (with MPEG4IP as encoder), or Icecast2 (using FFMPEG as encoder).
The research also talks about codecs, focussing on open-source codecs, and takes into account licensing/patenting issues.
I briefly spoke about three related projects than I am involved in. All are related to mobile phones.
1. Audio presents at radio documentary Grenzeloos Geluid
I worked with Nathalie Faber and Carolien Euser of artist collective cut-n-paste on "Callcentre 211" that ran during radio documentary festival Grenzeloos Geluid. Participants registered their phone number at a desk, and were called 15-20 times during the event. After answering their phone (or dialing their voicemail) they heard poems, narrations, soundscapes, music, etc.
I developed this system mostly using Asterisk, a fabulous open-source voice over IP system.
