The technology behind video conferencing, video streaming, audio calls etc, is in fact, very simple.
However, to do it well is infinitely complex.
We have so much bandwidth nowadays, that taking a frame from a webcam, sending it as is, and
in real time, is no big deal, and it can be done with the most minimal of
Have you noticed, a lot of video conferencing solutions, require you to wear headphones ? To prevent audio
echo ?.. Well this is one good example of complexity.
The seemingly simple job, propels this initially trivial task of taking
quick photos from a web cam in succession and sending them live, to a completely
All of a sudden, we are now in the world of hard core acoustic science, sub-microsecond
algorithm and software concepts to analyze the very building blocks of audio and
detect and recognize ones own voice being repeated a milliseconds again the
future, the root of what causes the annoying double talk.
Here at, CuSeeMe.tv, not only you will be in the front row, and witness
the development, refinement and launch of the amazing new service, I'm going
to explain the inner working of our technology in easy to grasp , bite size
chunks of information.
Before we begin, let's look at some of the technical jargon, you
may encounter when reading about the technology behind video conferencing.
