Chapter 1-System Overview
H.239 / People+Content
Video Clarity™
IVR-Enabled Conferencing
1-8
The H.239 protocol allows compliant endpoints to share content. By
default, all Conferences, Entry Queues, and Meeting Rooms launched on the
RMX have H.239 capability. This protocol is also supported in MIH
Cascading conferences.
Conferences can include a mix of endpoints that support H.239 or
People+Content.
People+Content is Polycom's proprietary equivalent of H.239.
The Video Clarity feature applies video enhancing algorithms to incoming
video streams of resolutions up to and including SD. Clearer images with
sharper edges and higher contrast are sent back to all endpoints at the
highest possible resolution supported by each endpoint.
All layouts, including 1x1, are supported.
Video Clarity can only be enabled for Continuous Presence conferences in
MPM+ and /MPMx Modes.
Interactive Voice Response (IVR) is a software module that automates the
connection process and lets participants perform various operations
during ongoing conferences. The participants use their endpoints'
keypads and remote control to interact with the conference's menu-driven
scripts using DTMF codes.
Operations that can be performed by participants or chairpersons during
a conference include:
•
Manually terminate the conference.
•
Mute or unmute the participant's audio channel.
•
Adjust the participant's broadcasting and listening audio volume.
•
Play the Help menu.
•
Mute or unmute undefined dial-in participants upon their connection
to the conference.
•
Request a Roll Call and stop the Roll Call names review
