Design a Multi-Source Conference Room Integration

Est. 70 minCompetency: Design an integrated room with control and conferencing.

Learning objectives

Design an integrated conference room with multiple sources.
Define the control architecture and sequence.
Integrate video conferencing with control.
Specify feedback for every state.

Lesson content

Bring it together: design a conference room with laptop BYOD, a codec for video conferencing, dual displays, a PTZ camera, ceiling mics on a DSP, and a touchpanel. Define the control architecture and sequence of operations.

Architecture

Laptop and codec as sources; matrix switcher routes to dual displays.
Codec handles far-end audio; DSP handles local mics and speakers with AEC.
PTZ camera feeds the codec; presets for wide/tight.
Touchpanel drives the processor, which coordinates everything.

Sequence of operations

START:
  display power ON (both) -> confirm
  route LAPTOP -> DISPLAY_LEFT, CODEC -> DISPLAY_RIGHT
  camera preset WIDE -> confirm
  dsp unmute program; volume 50
  roomState = ON

JOIN CALL:
  codec dial(uri) -> wait call=ACTIVE
  mute program audio
  camera preset TIGHT
  route far-end video -> DISPLAY_RIGHT

SHARE LAPTOP during call:
  route LAPTOP -> DISPLAY_LEFT (and to far end as content)
  keep call audio active

SHUTDOWN:
  mute program -> codec hangup if active -> power off displays -> STANDBY

Dual-display logic

Dual displays let users share content on one and see far-end participants on the other. The sequence handles the common states: local presentation, active call, content share during a call, and shutdown.

Worked example

User taps Start, then Join Call. The processor powers both displays, routes laptop left and codec right, dials the meeting, mutes program, moves the camera tight, and shows 'In call — sharing laptop' on the panel. Each state reflects real feedback from the codec and switcher.

Implementation checklist

✓Architecture covers all sources, displays, codec, camera, DSP.
✓Sequence handles start, call, share, and shutdown.
✓Each state has a feedback source.
✓Dual-display routing defined for each state.

01. Integrated room: laptop + codec sources, dual displays, PTZ camera, DSP mics, touchpanel.
02. Sequence: START → JOIN CALL → SHARE LAPTOP → SHUTDOWN.
03. Dual displays: content left, far-end right during a call.
04. Every state confirmed from codec/switcher/DSP feedback.
