Hi All,

A school I work with in Sydney, Australia is planning a new music block, with three classrooms and an auditorium.
The classrooms will have projectors which can have integrated HDBT. They need to have functionality for:
- Teachers laptop (HDMI/VGA)
- iPod/aux in
- Act as overflow rooms for the auditorium

The Auditorium will have FOH sourced through a digital mixer which will be located on the floor, and a projector with HDBT for vision.

Video Inputs include:
- AV Room Bluray player
- Camera/ AV Room Video mixer
- AV Room Computer (HDMI)
- Stage Laptop (HDMI/VGA + stereo audio)

Audio Inputs
- Mixer feed
- Bluray player

The mixer needs to have inputs from the two computers simultaneously, as well as the bluray player.

The overflow feed would be used for playing something straight from a bluray or the PCs, or in a proper lecture, these would all run into the video mixer along with a direct camera feed, so you could send a PiP feed with presenter/presentation back to the matrix. Audio (when needing multiple sources) would be sourced from the (video) mixer, via HDBT through the matrix mixer or direct out (from the digital mixer - hope that makes sense)

How would the routing work?

I'm probably over-complicating things but here is how I'm guessing it might go:


Auditorium

Bluray -> HDMI -> HDBT Matrix mixer
-> HDBT 1 -> Projector
-> HDBT 2 -> HDBT receiver -> RCA/TRS -> Mixer -> FOH
-> HDBT 4 -> Classroom Matrix mixer

Video Mixer/Camera -> HDMI -> HDBT Matrix mixer
-> HDBT 1 -> Projector
-> HDBT 4 -> Classroom Matrix mixer

AV Room Computer-> HDMI -> HDBT Matrix mixer
-> HDBT 1 -> Projector
-> HDBT 2 -> HDBT receiver -> RCA/TRS -> Mixer -> FOH
-> HDBT 4 -> Classroom Matrix mixer
-> HDMI -> AV Room Video Mixer

Stage Laptop -> HDMI/VGA-Aux in -> HDBT Transmitter -> HDBT Matrix mixer
-> HDBT 1 -> Projector
-> HDBT 3 -> HDBT receiver -> RCA/TRS -> Mixer -> FOH
-> HDBT 4 -> Classroom Matrix mixer
-> HDMI -> AV Room Video Mixer

Mixer feed -> RCA/TRS -> HDBT Transmitter -> HDBT Matrix mixer
-> HDMI -> Video Mixer


Classrooms

Teacher PC/iPod -> HDMI/VGA-Aux in -> Classroom Matrix Mixer
-> HDBT 1 -> Projector
-> HDBT 2/HDMI/RCA -> Amp/speakers

Auditorium Feed -> HDBT -> Classroom Matrix Mixer
-> HDBT 1 -> Projector
-> HDBT 2/HDMI/RCA -> Amp/speakers


Suggestions/changes? Surely this can be simpler? Does anyone have recommendations of local (Sydney) system integrators who are looking at this tech?
