Skype
for Video Streaming over BGAN
Our tests of using Skype as a Video Streaming solution
over BGAN using a Hughes 9201 terminal were better than expected.
With a streaming rate of 100Kbps, the resolution and speed
of
the
connection
for one or
two-way communication was quite passable.
We used a standard tripod video camera connected
to a laptop using a web camera with standard video
RCA jacks for connecting audio and video directly
to the computer
(bypassing
the intended web camera itself). Specifically, we used the
Lorex DMC2161 web cam. No external power, other than connecting
to the USB to the laptop, was necessary.
The Skype software recognized the "web cam" and
we configured the software to start video streaming upon
connecting to another Skype user on the Internet.
There is the option to stream one way, or in
both direction
for video conferencing, although configuration is needed
at both ends.
We experimented using both Background IP connection and the
Streaming 256Kbps for the BGAN connection. The audio was
slightly better using the Streaming 256 in that it had fewer
audio drop outs. The "shared" Background IP connection was
not tested more than a few times, and the test was in the
California BGAN spot beam. Other locations on the planet
may vary we
assume. Streaming however is committed and should work the
same everywhere.
Doing some quick math, if we're streaming
at about 100Kbps for 60 seconds, then we've transferred a
bit under 1 MB for only one direction... 2MB if we're streaming
both directions for a video conference.
Bottom line is we think Skype Video over
BGAN is a very cost effective means of broadcasting live
video from anywhere to anywhere.
