Hi all. Was looking for help on this topic.
I am the tech at a local church and we have a Roland VR50HD video mixer streaming and recording into a pc at 720p. We also have a monitoring TV in the lobby of the church but it has a serious audio / video delay. It is driving everyone in the church nuts because we can hear the sermon live just on the other side of the door, but the foyer TV is literally 1/2 a second late. If anyone turns the volume up on the TV, an incredible echo results. The delay can be for a number of reasons, most notably because the previous tech modulated the digital signal to analog CATV channel 2 for distribution to the lobby. I will be 86ing the mod.
My question relates to latency when using the mini SDI distribution converters, as well as the mini SDI to HDMI converter. If I take the SDI signal out of the mixer and distribute to all monitors through the BlackMagic SDI distribution converter (as well as the SDI to HDMI converter as a few TV's don't have SDI inputs), will I be faced with any significant delay? The specs don't say too much.
Also, for the TV's that don't have an SDI input, can I split the individual SDI lines to component video for those TV that don't have and SDI input? The TV's we have in the church are not the newest and the budget isn't there to replace all the monitors.
We also have a digital audio board and my other thought was to take the videl and audio separately from each to distribute, right at the source of each before any delays could occur from mixing. I'd have a digital signal directly out of the camera (not sure if it has an SDI output) and take audio from the board then combine (somehow) for distribution. To me that seems most logical because both sources would be before mixing. Is that a crazy thought? If not, how would it be achieved?
Any help with this seemingly silly problem would help. I should also mention that I am willing to replace or run new distribution cabling.... that's a non-issue AFAIC.
