videoteque · 28th August 2009

Do you want to see the Berliner Philarmoniker today at 19.00 (europe time)??

Sorry, I thought it was free, but it isn't!!!!!!

Anyone has experience in live broadcasting on-line??

Yes, what do you want to know?

Everything!

I think I know several things, all very theoretical. You need to provide an audio/video feed to one computer which is connected to internet and which has a software that "broadcast"s the signal??

In real life, what internet connection do you need?? Do you need a special "server" or something?? Am I missing something???

Usually, you do a broadcast as if for live television, there's just someone (usually not locally, most often in another city) that encodes it and streams that encoded video..

My live streaming things have always been put on sattelite and have been encoded somewhere else.. It's usually too hard to get a dedicated internet connection for streaming on-site..

Can you or someone else comment how much bandwith do you need??

I don't see myself renting satellites... yet!

I guess it's both a bandwith and reliability thing.. But that's for live streaming.. I've done jobs where they recorded the video to disk and put it on a server locally..

Speed and such I do not know..

Thanks Huub!

The live thing is nice, but internet is wonderful because you can find things you never thought you would find! So the live broadcast can be attempted in an experimental way, the definitive posting of the videos can be made with higher quality and control...

Yeah, definitely!

I have been partly involved doing this once. We used a local computer equiped with a Decklink SDI card to encode to WMV 700Kbit/s. The stream was sent to a server on a 2,5 Mbit ADSL connection, where 2Mbit was dedicated for the video stream. The server was located in a national "hub" with a dedicated 100Mbit connection to the internet.
I was told that having 3 times overhead bandwidth is common practise.

2Mbit is one thing, 100Mbit is another thing!!!!!!
