We have upgraded a video distributed system in a church to HDMI from VGA
But they have an analog PTZ camera. Composite source.
There are 13 HDMI screens(LED) in the church building The analog picture is also transmitted to a nearby building together with sound which is delayed so that’s ok.
The live screens are fed via a Kramer VP 728 and the outside picture another VP 724. The HDMI distribution in the room is over CAT6 using AAVARA PB5000+ units.
Our main headache and problem is video latency and delay on the live screens from the analog camera.
I have done tests and when we feed a HDMI camera directly into the AAVARA HDMI over Cat6 system the latency is acceptable. But once you convert the analog camera via the Kramers and then onto the HDMI the latency and lag becomes very bad. We have tried a stand alone composite to HDMI unit to feed into the system and then its also bad
Its very disturbing as many watch the screen and listen to the sound system and the lip sinc is very bad. We can delay the sound a bit but I don’t think enough to sort out the problem
Which PTZ camera and switching system could we look at? We want something with minimum latency live and smooth transitions as they also use a laptop with HDMI. The KRAMER has a second or two delay and black screen before switching.(I have no idea of how many frames) So the main problems seem to be the converting from Analog to HDMI and then the Kramer scalers.
