CPM (Continuous Presence Multipoint) in Video Conferencing

CPM ON (1):

• Used in video conferencing where multiple participants' video feeds are combined into a single stream.
• Allows a grid/multi-screen view (e.g., Zoom, Microsoft Teams, Cisco Webex).
• Required for MCUs (Multipoint Control Units) handling multi-party calls

CPM OFF(0):

• Used for single video streams (one-to-one calls or a single video source).
• Ideal for direct peer-to-peer calls (e.g., a single camera sending a video feed).
