## THE SYSTEM

just sketches for now.

### MAIN TABLE CONCEPT

the main table should be interconnected, with two ATEMs connected to each other and to two computers, and with this whole system getting 4+ feeds back from the **a8k.a** or **hub.a**.

* sources
* main table
* 2x computer HDMI-outs
* split under table 1x4 and sent to both ATEMs and monitors
* 2x overhead SDI-outs
* sent back to Constellation
* 4x overhead XLR-outs
* sent back to C200s
* 1x AMX pgm feed HDMI-out
* split and sent to am.a and converted and sent to a8k.a
* camera position
* 8x Constellation outs
* 4x Camera SDI-outs (to Constellation)
*
* destinations
* main table
* 8x AMX HDMI-ins
* get 2x HDMI direct from overheads
* get 2x HDMI direct from computer feeds split
* get 4x from the Constellation, converted SDI => HDMI under table or above truss
* 4x AM HDMI-ins
* pgm from AMX
* pgm from Constellation
* computer 1
* computer 2
* 2x computer usb-ins
* get one from AMX
* get one from AM
* camera position
* 1x confidence monitor HDMI-in
* 2x display monitor HDMI-ins
* 12x Constellation SDI-ins
* 4x main camera XLR-ins
* think about adding a mixer and multitrack recorder
* far wall
* 5x screens
* sdi2hdmi converters on the wall

### AIRTABLE SCHEMA

[The Airtable in progress lives here.](https://airtable.com/tblQhCyZzf5liD2tS/viwNHBYNrt5z8oM7v?blocks=hide) But let's outline the basic schema here.

* CONNECTIONS
* from (links to OUTS)
* lookup from source device
* to (links to INS)
* lookup to source device
* cable (links to CABLES)
* signal
* modified
* INS
* device (links to DEVICES)
* port number
* connectorType
* OUTS
* device (links to DEVICES)
* port number
* connectorType
* CABLES
* id
* connectorType
* cableType
* color
* length
* DEVICES
* make
* model
* id
* manual link
* type
* location

Notes:

* studio@xyz needs to be on this airtable
* we should check connections routinely using last modified (i.e. at weekly or monthly intervals, depending on the location)
* in the connections table, have a view that groups by source device and another that groups by destination device
* the goal of cable type (and color for that matter) is easier identification when labels disappear or midway through a run
*
