I guess that would depend on if the audio is distributed via the HDMI or some other way. Except for ASL, I think it's all the same video.

Yes, ASL is different video. Also the chapel camera is different video.

Audio is a good question. I hope it's coming over HDMI.

Many years ago I went to a nearby stake to help them solve satellite problems between conference sessions. If I remember correctly, at that time, that stake had a button panel where they selected the audio feed for each room's ceiling speaker and they didn't have modulators for each language, so it's possible they'll do a panel like that for choosing the HDMI feed to each room.

Historical musings I vaguely remember an a/v remodel we had in the early 1990s and I think the church wasn't into modulators at that time and we had to push to get modulators for the languages, as someone at the church didn't think modulators were a good idea. I think our stake's original satellite system was installed in the early 1980s by the stake before the rise of the FM group. Whoever installed that used modulators. We had done some enhancements, including adding a BNC patch panel. I was sad to see all the BNC connectors lose out to F connectors with church standardization, although I did take a liking to the AVS-1 control panel they installed. We actually hung onto that panel through a subsequent remodel. Even though it had been discontinued, when we asked the a/v architect about it, he said he liked that panel and would leave it in.

This is one of the bigger problems when an STS --> HC --> FM --> Contractor is the process. When the HC and I walked through the issues with the CCTV we understood that it would be a focus of the work.

Yes for my install there is an input and and output at the podium.

There was NO change to audio Distribution or for that matter video distribution from the Cabinet to the rest of the building.

They just started the A/V remodel in our stake center. I'll try to report back on what they ended up doing.

I wanted to report back on our system after doing some testing.

Input1 - mounted Camera in the Chapel (camera was upgraded) comes through to the teradek as 720p60
Input2- Podium (there is an HDMI + 3.5m audio input plate)
Input3- Overflow (there is an HDMI + 3.5m audio input plate) - This was done a my request - I don't know if this is normal for them
Input4 - Sattelite
Input2,3,4 - require the satellite override to be pushed at the podium to hear the sound in the chapel and the rest of the meetinghouse.

Output1 - TV mounted at the cabinet (7 inch - analog) - Input2,3,4 all have audio/video Input1 currently has only the video of the Camera. I have since asked them to tie in the audio, as I was speaking to them they said, well, the chapel system is ported to the library, so they figure I could use the library sound to 'hear' what's going on in the chapel. I told them that I needed the audio to validate that audio/video is going to the Teradek - only way to troubleshoot when a webcast has 'no audio' - first thing I need to do is hear it at the monitor @ the cabinet to double-check.
Output2 - Teradek HDMI (for video) and chapel audio (analog) line in like it was before.

Input2 and Input3 are HDMI over Ethernet, however, the Ethernet plugs directly into the Extron which (I validated with the contractor) has internal mechanisms to translate Ethernet back to HDMI) means that I can't grab that HDMI signal to put into a mixer to do multiple cameras for my webcast, or at least I haven't figured out how to do that without incurring more hardware cost. I was hoping there would be EthernettoHDMI in my cabinet I could snag 'before' going into the building system, taking it into a switch, then putting it back into the system like I used to with the RCA/Analog system it replaced. I'm stuck using their switcher which can detract from the meeting when switching between two inputs. I'll play with it more, but at this point I'm not seeing signal into my teradek so I'm working on at least a single signal right now.

Just a quick update. It appears that what we got was not an HDMI upgrade to the Meetinghouse, but a partial upgrade based on what they could do within the budget. I just wanted to be clear because some have talked about different installs in this thread.
