Help with video streaming .. |
|
|
Hi,
I wish to do this..
Use a fixed camera with remote zoom at a location USA to record in good
quality a 1 hour speech.
I want it then streamed thru the net to a PC in Australia to be recorded
on HD.
Ideally it can all be done from the PC in OZ.
Any ideas what I need for this to be possible as well as any suggestions.
Thanks
David

Thank you Neil, I appreciate your time and details.
I will try and assimilate it all, follow the links then get back with
the left overs!
At the moment they don't have any equipment, that is to come when I am
sure what is needed and the most economical way to go. It is a church
group so money is at a premium.
Thanks again,
David

You could use one of :
Helix Producer (Real Networks)
http://helix-producer.helixcommunity.org/downloads.htm
Darwin Server (Apple / Quicktime)
http://developer.apple.com/darwin/projects/streaming/
Windows Media Encoder (Microsoft)
http://www.microsoft.com/windows/windowsmedia/9series/encoder/default.aspx
All of these can broadcast an encoded (compressed) stream over the
net, using a port number of your choosing. You'll need to find a way
to get to the PC which is doing the encoding, as well as making sure
the camera will operate with the encoder - most of them support
firewire, webcams and so on, as well as standard digital audio sources
(sound cards & capture cards).
Pick or configure a very high quality capture profile, and ensure your
network ping times are good so you don't get any dropouts on the
routers along the path at live-time. You'll also need to have a fast
machine with lots of memory to do 'high quality' (lets say, 1024x768
at 25fps with 44khz lossless audio)
Extensive 'shootout' style review of the pros and cons here :

Ideally it can all be done from the PC in OZ.
The trick will be actually starting the encoder when you want to begin
the broadcast. You'll probably want to archive the file too when you
encode, and transfer the entire file as an archive at the end of a
broadcast.
Stuff like VNC is good for remote-controlling computers over the web,
http://www.google.com/search?hl=en&q=VNC+client+server but watch for
security issues ;-)
Any ideas what I need for this to be possible as well as any suggestions.
Since you're low on details of what you've got available to you, the
process description is equally slack <g
Thanks
David

What do YOU mean by "streamed"? If you are expecting to
get 60 minutes worth of quality video half way around the
world in real time without any network glitches, you're
dreaming.
If you mean that you want to capture the video to a 13GB
file and then transfer it over the internet to a computer on
annother continent, that is likely doable. Of course, you
need broadband at each end or it will take forever. There
are file splitter utilities that will break the file up into more
manageable pieces (500MB?) and then re-assemble at the
other end.

Define "all". Don't expect to see the video fast enough and
with enough reliability to remote control a camera for a
one-hour program. Not over the public internet. The first
big virus/worm storm will wipe you out.

Shoot live to tape (as in a camcorder). You can capture live
along with it, but if anything goes wrong, you will be happy
to have the tape "backup".
Use FTP, etc. to transfer from source comptuer to destination
computer. I'd use a file splitter to make smaller pieces so that
if you have to recover, you don't have to start over from scratch.
Of course you remember that USA is in NTSC-land while you
are in PAL territory (and all the implications thereof.)
According to the DVD "making of" video, this is how they
accomplished editing LOTR in NZ while concurrently
scoring and recording the music trax in London. They sent
scores of GB over the internet every night so that the
producers in London could see what was being edited in
NZ. |

What's your budget?
Could you consider using videoconferencing to capture the speech? If
you use a videoconferencing system, you could monitor and control the
camera in nearly real time, plus plug your computer into the video out
of the conference system to encode the video (from either end). Options
for videoconferencing would be IP or ISDN. IP would probably be okay,
but you'll run into problems if there are network bandwidth issues.
ISDN will work fine, but you have to pay overseas long distance charges
per circuit (6 circuits for 384k).

Where I live, you can book Ku and C-band satellite time for under $400 an hour.
That's truly live, broadcast quality, no delay. As many downlink sites as you
want. |
