Meeting & conference rooms

• The laptop sends HDMI to the display and exchanges camera, microphone and playback audio with a USB video bar.
• MR-01 reference diagram with separate HDMI and USB paths, local controls and the laptop's network call.

PC

1 user laptop Call application and screen sharing

DIS

1 display 65-inch candidate; speakers off

BAR

1 USB video bar Camera, microphones, AEC, speakers

REM

1. PC → DISHDMI: selected material
2. BAR → PCUSB camera + processed microphone
3. PC → BARUSB playback; internal AEC reference
4. PC ↔ REMIP call via client network

No room PC or managed platform in this baseline. HDMI and USB are separate; laptop charging is separate. Reference design: project selection and tests required.

• An SDI camera reaches the PC through USB capture. The ceiling array sends processed speech; playback feeds two speakers and the array's echo reference.
• MR-02 reference diagram showing SDI-to-USB capture, microphone AEC, USB audio, Dante routes, PoE and PC controls.
