Steve,
This is an interesting concept, but:
1. in my opinion the cost just for the transmitter is quite high ($1690-$1990)
2. you still need to run some wire between the camera/microphone and the device
3. the question is where you will keep your recordings? on the decoder/receiver
which will add another $1600-$1900 to the cost
4. will you have access to recordings on the receiver, such that in a case of
lost connection with the core (or missed transmission) this can be recovered.
I think this might be an interesting product for capturing a screen
together with an IP-camera. We UiB have looked into solutions where we
can depend less on a stationary PC in the class room, and rather have a
virtualised agent.
We have seen that the Galicaster agent is much easier to configure for
rtp streams than the native MH agent. We are currently working with two
scenarios:
1: have a device (either epiphan vgabroadcaster or the epiphan MCD)
capture the screen and stream it to rtp. It is here the Tcube can be a
replacement. An ip-camera does the same. Then a galicaster agent takes
these streams as an agent. The drawback here is that the output for the
galicaster is native, and without a pc in the room, no feedback is
provided for the lecturer. If galicaster had a web interface we would
probably go for that right away.
2. Get the MCD to work and accept the (less than optimal) quality of the
s-video input. We see that the firmware on the MCD is also quite buggy,
and are very unsure if it is production worthy.
In my only few months experience with the MH system, the best solution is to
have an autonomous capture device, permanently placed in the lecture room.
And so in the case of any problem, recordings can always be uploaded at any
time 'by hand' to the core.
You would probably be better of if you design a laptop based capture device,
but then there is unavoidable hazard when moving laptop around and making every
single time connections to the network and to video/audio devices.
We did use such idea in the past with MiniMac based Podcast Capture portable
device, which we found very unpractical.
Anyway, an interesting concept and I wonder what other peoples will say?
Best,
Leslaw
