Steve, Drew, Bob, and Members of LCTG,
It's nice to know that groups similar to ours (small, limited resources,
desire to keep things simple and cheap) are all landing on essentially the
same architecture for their Hybrid Meeting systems. We have now seen two
additional groups (The Brandeis Bolli study group) use essentially the same
architecture as we are planning on using. Here are some common
characteristics:
1. *Use Zoom as the shell for everything that goes on in the meeting,
regardless of location* -- for the attendees in the meeting room or
remote location: they all hear and see the same content on their video
display and speakers. For those in the meeting room, the sights and sounds
of the presentation travel through the air of the room. For those in
remote locations, those same sights and sounds travel over the Internet.
2. The *Presenter joins their laptop to the Zoom conference and in the
course of their talk*:
1. The presenter delivers illustrations for their talk using the Zoom
share screen mechanism.
2. The presenter speaks from their laptop for transmission to all
participants both local and remote. Voice is captured by a wireless
bluetooth Lavalier mic.
3. The presenter's image is captured by their laptop camera and fed
to the Zoom meeting.
3. *Audience members ask questions using normal Zoom interaction
mechanisms*.
1. The meeting host will recognize audience members before they start
asking their questions.
1. For *those in the meeting room*, people with questions will
raise their hands and the meeting host will recognize them
before they ask
their question. We will use a Handheld mic (transmitter)
that connects to
the Meeting Computer (*MC*) through a UHF signal to a receiver
that plugs into the *MC* through a USB port.
2. For *remote users *we will use the *Zoom Raise Hand* feature
when they have a question. The meeting host will recognize
remote users
before they speak.
3. One of the advantages of using Bluetooth for the Lavalier mic
and UHF for the Handheld mic is that the signals won't
interfere with each
other.
4. The *MC *is a member of the Zoom conference. The video output of
the *MC *to the Zoom conference is from a webcam aimed at the audience
that is connected to the *MC* through a USB connector. This allows
remote users to see what is going on in the meeting room. The audio output
of the *MC *is the output of the handheld wireless mic.
There are three external I/O devices connected to two computers:
1. A wireless *Lavalier mic* is connected via bluetooth to the *presenter's
laptop* to capture the presenter's talk.

2. A wireless *Handheld mic* is connected to the *MC* to capture the audio
of questions from people in the meeting room

UHF Handheld Microphone Transmitter and Receiver
A *Webcam *aimed at the meeting room audience is connected via a USB wire
to the *MC *to capture the scene in the meeting room.
