[44net] Latency in various protocoles

Im experimenting two net cameras on the AMPRNET One is http streaming the other is RTSP streaming The http uses tcp port 80 the rtsp uses udp (dont remember the port now ) The http replace photo every 250 MS (i assume after it get ACK and then send the next image) ( i see about 4 frames per second) and make a traffic of about 1000 kbit/sec the RTSP send photos in about 10 frames per second and produce traffic of about 500-800 Kbit sec all this over the amprNet May someone explain this ? how come that the RTSP photo is like movie and the http is 4 frames per second (of course that if i view the http camera direct on the net i see the 10 frames per second i set the camera for) And why i tell you all of this ? Because i wonder how a DMR repeater connection will work on the amprNet ... If i can see in RTSP video without problems or frame loss should a VOIP (or more exact) data stream of the DMR work ? after all it is less data .... Is there anyone that can light my eyes on the subject ? Regards Ronen - 4Z4ZQ
