Hello everyone,
I'm writeing diploma at my school about distance learning. I have few
questions and maybe someone would explain me some hardware things? It
would be great!
Imagine such video system. One Canon camera Canon VC-C4, few
microphones with mixer, another document camera, and interactive
whiteboard. Also we have computer for person who present all types of
data (power point and so on) and all of this is plugged into one
computer which records it and after all delivers wma files. There is no
video server from canon for this camera, it is just plugged to some
video card inside pc.
Ok, so these are my questions:)
1) What does it mean that canon camera support some kind of higher
compression for prepareing signal for streaming? How it does it?
2) How it could be merged together? How do you think? What commercial
software suppoort such operations? It is done automaticcaly after
lesson.
3) What codec is used in wma? Is it some kind of mpg4?
4) What video card can be used?
5) How can look like conversion? I can imagine that video is collcted
in some compression during lessons, so on audio and white board and it
is merged together after all? But how?
maybe someone could reply me or advise to read some articles about it?
There is no commercial software used in this process except final wma
by windows media, so I wonder how it can work together and what
protocols can be used and so on.
Thanks in advance!
Peter,
