I have a viedo stream coming from one site, I want to do the following with the minimum delay possible:

I want to duplicate the stream (inside the router - preferred) and send it to a few more locations one of them is local network and the rest - on other networks.

I want to be able to do it to several streams simultaneously.

Is it possible to do this - using network devices only ? What device is capable to do this ?

(I can always record the stream and rebroadcast it - but that's a lot of delay, I'm looking for functionality that similar to port duplicating, but on higher layers).

Thanks.
