• Application Diagrams

About this Guide

The MediaPort 200 User Guide describes the Extron MediaPort 200 HDMI and Audio to

USB Scaling Bridge and provides instructions for experienced installers to install, configure,

and operate it.

This guide contains two different work flows that provide unique instructions and

information. These modes are Standalone MediaPort 200 and Mediaport 200 with external

DSP and AEC (see Theory of Operation on page 7). While much of the information is

universally applicable, pages that contain information unique to a specific audio mode are

marked with Standalone MediaPort 200 or MediaPort 200 with External DSP and

AEC in the right margin of the page.

In this guide, the terms “MediaPort 200” and “MediaPort,” are used interchangeably to refer

to this product. The terms “external DSP matrix processor, “external DSP Processor,” and

“DSP” are used interchangeably to refer to the external DSP processor when one is in use.

About the MediaPort 200

The MediaPort 200 is an HDMI and audio to USB scaling bridge that interfaces between

professional audiovisual equipment and computer-based conferencing software to facilitate

video conferencing with soft codecs. Incoming HDMI video at multiple resolutions is scaled

and output via USB to a computer. Other features include Auto Memory, Auto-Image, and

internal test patterns.

Audio DSP allows for incoming digital and analog audio signals to be mixed and embedded

on the USB output.

Setup and control are provided via Extron Product Configuration Software (PCS), front panel

controls, and SIS (Simple Instruction Set) commands. The MediaPort can be configured

and controlled by a host PC running Microsoft

®

Windows

®

and Extron PCS configuration

software via the MediaPort USB Config and Ethernet ports. SIS commands can be issued

via the RS-232, USB Config, and Ethernet ports.

The 1U high, half rack wide, 9.5 inches (24.1cm) deep enclosure can be rack mounted

or placed on or underneath furniture. For information on mounting options and UL rack

mounting guidelines see Mounting on page 158.

®

, Linux and other operating systems.

• Video scaling provides USB output from 320x180 to 1080p/24 to match

common software codec requirements — Ensures optimal quality of camera or

computer video content for far-end conferencing.

• Scaled USB streaming video output with MJPEG encoding.

• Integrated audio DSP — Provides audio mixing and signal processing capabilities for

4x2 audio. The DSP is optimized for integration with mic and program audio sources as

well as software codecs, hardware codecs, external DSP, and sound reinforcement.

• AEC reference output — Provides far-end audio to an external AEC-equipped DSP.

This audio is used by the external DSP as a reference signal for AEC (acoustic echo

cancellation) processing. This ensures echo-free conferencing for far-end participants.

• HDCP-compliant HDMI input and loop-through — Provides an output signal for

local display, AV system, or a hardware codec, enabling the content to be monitored or

shared without the need for a separate distribution amplifier. Both the HDMI input and

loop-through are HDCP compliant.

• HDMI audio de-embedding — Embedded HDMI two-channel PCM audio can be

extracted to the integrated DSP for processing and mixing.

• USB 4x2 audio interface — The USB connection provides a 4x2 audio interface

with a computer, similar to a standard USB sound card with send and return audio

capability. This allows the MediaPort 200 to send a two-channel audio source mix to

the personal computer, and the computer to deliver its program audio plus two-channel

communication audio from the far-end to the MediaPort 200.

• Supports popular software communications platforms including Microsoft

®

Lync

®

/ Skype

®

for Business, Adobe

®

Connect™, and Cisco

®

WebEx

®

.

• Accepts HDMI computer and video resolutions up to 1080p/60 and 1920x1200.

MediaPort 200 • Introduction 3

• High performance deinterlacing for signals up to 1080i — Features highly

accurate deinterlacing for 480i/576i/1080i signals. This ensures absolute detail and

fidelity in the reconstructed progressive video frames, including 3:2 and 2:2 pulldown for

interlaced signals originating from film content.

• Mic/line input with 48 volt phantom power — A mic or line level audio source can

be mixed with program audio. Selectable 48 volt phantom power allows the use of

condenser microphones.

• Front panel LED indicators for HDMI and USB signal status — Provides visual

feedback for HDMI input and loop-through signal presence, HDCP status, plus USB

signal presence for the host computer, video send, audio send, and audio return.

• Logo image display — The MediaPort 200 can be set to automatically display a

user-supplied image file whenever no signal is present at the HDMI input.

• Aspect ratio control — The aspect ratio of the video output can be controlled by

selecting a FILL mode or a FOLLOW mode.

• Auto Input Memory — When activated, the unit automatically stores size, position,

and picture settings based on the incoming signal. When the same signal is detected

again, these image settings are automatically recalled from memory.

• Internal video test patterns and pink noise generator for calibration and

setup— The MediaPort 200 offers several video test patterns to facilitate proper

system setup and calibration and can provide an active output when an input video

source is not available. The pink noise generator is selectable for all audio outputs,

including USB audio to the computer, and aids in optimizing audio output levels.

• Picture controls for brightness, contrast, horizontal and vertical positioning,

and sizing.

• User-selectable HDCP authorization — Allows the unit to appear HDCP compliant

or non-HDCP compliant to the connected source, which is beneficial if the source

automatically encrypts all content when connected to an HDCP-compliant device.

Protected material is not passed in non-HDCP mode.

• HDCP Visual Confirmation provides a green signal when encrypted content is

sent to a non-compliant destination — A full-screen green signal is sent when

HDCP-encrypted content is routed to the USB output, or to a non-HDCP compliant

display on the HDMI loop output, providing immediate visual confirmation that protected

content cannot be viewed.

• EDID Minder

®

automatically manages EDID communication between

connected devices — EDID Minder ensures that the source powers up properly and

reliably outputs content for display.

• Auto-Image™ setup — When activated, the unit automatically optimizes the image

by analyzing and adjusting to the video input signal. This can save time and effort in

settings up a newly connected source, particularly in presentation environments where

different guest presenter laptops with various output resolutions will be connected.

• User image presets — 16 memory presets are available to store and recall optimized

image settings.

• Parametric EQ, filters, and compression on all inputs — Equalization and

filters are available to fine-tune frequency response for microphone and program

sources. Compression is available to compensate for sources with widely varying or

unpredictable signal levels.

MediaPort 200 • Introduction 4

• Parametric EQ, filters, and limiter on USB and line outputs — The MediaPort 200

provides nine-band equalization for room tuning. It also detects actual onset of clipping

by comparing input and output waveforms. Gain is automatically reduced without

audible artifacts to protect the audio system from clipping distortion.

• Microphone and USB audio ducking — Automatically lowers program audio level

when a microphone or far-end USB audio signal is detected, eliminating the need for a

separate audio ducking processor.

• 24-bit/48 kHz analog-to-digital and digital-to-analog audio converters — High

performance converters preserve audio signal integrity for input and output signal

conversion.

• Fixed, low latency DSP — Input to output latency is fixed within the MediaPort 200

regardless of the number of active channels or processes, maintaining audio and video

synchronization.

• User-definable DSP audio presets allow quick recall of commonly used

configurations — Up to 16 user presets can be created using the Extron PCS

software application. Once created, presets can easily be recalled from the PCS

software or a control system.

• Mute and gain audio group masters — The MediaPort 200 provides pre-configured

group masters for consolidated mute and gain, simplifying real-time system control.

• Soft limits provide optimal master volume adjustment range — When using

external volume control, the master volume range can be regulated with soft limits to

maintain optimal minimum and maximum levels. This prevents operators working with

digital I/O, RS-232, or Ethernet control from exceeding pre-defined limits.

• Live DSP configuration — Allows live parameter adjustments while previewing or

metering them in real-time. This avoids the need to compile and upload a configuration

file to the device.

• Front panel controls with LCD display — Allows convenient access to configuration

and status of the MediaPort 200.

• Front panel USB configuration port — Enables easy configuration without having to

access the rear panel.

• Two digital input and two digital output control ports — Allow external triggering

such as a mic activation and muting, as well as illuminating mic status LEDs. Digital

inputs can also be used for recalling DSP presets and adjusting volume via contact

closure.

• +12 VDC, 100 mA remote power — Provides remote power for various applications,

such as LED illumination for mic status and mute.

• Front panel security lockout — Locks out all front panel functions. All functions are

still available through Ethernet, USB, and RS-232 control.

• RS-232 control port — Enables the use of serial commands for integration into a

control system. Extron products use the SIS™ - Simple Instruction Set command

protocol, a set of basic ASCII commands that allow for quick and easy programming.

• Built-in web pages — Enables the use of a standard browser for monitoring or

updates over an intuitive web interface.

• Easy setup and commissioning with Extron PCS - Product Configuration

Software — Conveniently configure multiple products using a single software

application. The software also allows configuration files to be downloaded for archiving

or configuring multiple systems.

MediaPort 200 • Introduction 5

• Compact 1U, half rack width metal enclosure — The half rack width enclosure is

designed for flexible mounting using a wide variety of Extron furniture and rack mounting

kits (optional). Passive convection cooling ensures silent operation.

• Includes LockIt

®

HDMI cable lacing bracket.

• Highly reliable, energy-efficient internal universal power supply — The

100-240 VAC, 50/60 Hz, international power supply provides worldwide power

compatibility.

USB Video

When the host PC is connected to the MediaPort rear panel USB B port, the host PC

requests a list of supported resolutions and refresh rates, which are supplied by the

MediaPort 200. When a Universal Communications (UC) application on the host PC is

launched, it requests the desired video resolution in real time from the MediaPort 200 based

on host PC hardware usage, available network bandwidth, and far-end UC application

window size.

This means that output resolution is determined by the UC application. It is not possible to

force the MediaPort to output a specific resolution.

Audio Functions

The MediaPort processes audio outside of the computer via a single USB connector,

enabling it to be used in a PC-based, software video conference without having to take an

analog output from the built-in computer sound card.

The audio functions of the MediaPort 200 are unique, depending on whether the device is

operating as a standalone device or in conjunction with an external DSP processor and AEC

(see Setting Audio Modes on page 17).

MediaPort 200 • Theory of Operation 7

Theory of Operation

This section contains a discussion on how the MediaPort 200 can be implemented,

including its two audio modes. This section also covers the signal flow within the

MediaPort200 in these two modes. The following topics are discussed:

• MediaPort 200 Operational Modes

• Speakerphones and AEC (Acoustic Echo Cancellation)

• Standalone Mode

• External DSP with AEC Mode

• MediaPort 200 Signal Flow

• Setting Audio Modes

MediaPort 200 Operational Modes

The MediaPort 200 works in conjunction with a computer “soft-conferencing” application

to create a hands-free conferencing environment. The MediaPort is recognized by the host

computer as either a speakerphone or an echo cancelling speakerphone, depending on

which audio mode is enabled. The MediaPort connects to a sound system and computer

to bring the far end audio and video into the local room, as well as program audio from

the computer or one of the MediaPort line-level inputs. The MediaPort accepts a single

microphone at the mic/line input or can accept a microphone mix from an external DSP

matrix processor. The following MediaPort audio modes are selectable in Extron PCS:

• Standalone (no external DSP) – This is the default setting. In this mode, the

computer recognizes the MediaPort as a Speakerphone and applies echo-cancellation

in the unified communications software. This mode is intended for use with a single

microphone connected to the mic/line input.

• External DSP with AEC – In this mode, the computer recognizes the MediaPort as

an Echo Cancelling Speakerphone which is intended to prevent AEC from being

applied in the unified communications software. This mode is intended for use when a

mic mix from an external DSP matrix processor with AEC (acoustic echo cancellation) is

connected to the mic/line input.

It is important to select the correct mode before configuring the MediaPort 200 with the

host computer. Changing the audio mode causes the MediaPort to reboot, after which the

computer recognizes the MediaPort as a different device in the newly established mode (see

Setting Audio Modes on page17 for more information).

MediaPort 200 • Theory of Operation 8

Speakerphones and AEC (Acoustic Echo Cancellation)

When a microphone or microphone mix is connected to the MediaPort and the MediaPort

is connected to a sound system to amplify audio from the far end of the conference, the

MediaPort functions in the same way as a speakerphone. In a conference call, the far

end talker is amplified in the local room and that signal can be picked up by the local

microphones and sent back to the far end. That audio is delayed and is then heard by the

far end talker as an echo of their voice.

This echo is often referred to as “acoustic echo” because it travels through the acoustic

space from the sound system to the microphones. A specific type of processing, called

“acoustic echo cancellation,” or AEC, is used to cancel the echo signal and prevent it from

being sent back to the far end.

Standalone Mode

In the Standalone audio mode, the computer recognizes the MediaPort as a Speakerphone.

In this mode, Speakerphone – MediaPort 200 is chosen as the audio device in Windows

and in a soft conferencing application such as Skype for Business. When a speakerphone is

the selected audio device, the host conferencing application uses its built-in AEC to cancel

the acoustic echo.

External DSP with AEC Mode

In the External DSP with AEC audio mode, the computer recognizes the MediaPort as

an Echo Cancelling Speakerphone. In this mode, Echo Cancelling Speakerphone

– MediaPort 200 is chosen as the audio device in Windows and in a soft conferencing

application such as Skype for Business. When an echo cancelling speakerphone is

the selected audio device, the soft conferencing application AEC should be turned off

automatically. In this case, an external DSP is connected to the MediaPort mic/line input and

the AEC is applied in the external DSP processor.

MediaPort 200 • Theory of Operation 9

MediaPort 200 Signal Flow

This section provides a more advanced understanding of the MediaPort signal flow. The

MediaPort fits into multiple conferencing applications with little or no additional configuration

other than setting proper gain structure and run-time mix levels.

Matrix Routing

Figure 4 on the next page is a basic signal flow block diagram showing the MediaPort

default configuration and available processing. Figure 3 below is an audio matrix routing

table that displays MediaPort 200 audio routing. Viewing the mix matrix routing from the

perspective of the outputs:

• USB Out

• Set to Dual Mono (default, stereo available), left and right signals are summed.

The following line inputs are routed to the USB Out L/R:

• USB Playback

• HDMI In

• Line In

• Mic/Line In is routed to USB Out L/R

NOTE: USB Communications audio is never routed to USB Out.

• Line Out

• Set to Stereo (default, dual mono available). Line input L is routed to Line output

L; Line input R is routed to Line output R. The following line inputs are routed to

Line output L/R:

• USB Playback

• HDMI In

• Line In

• USB Communications – There is an option to mute this signal to the line output

• Includes both line input signals and USB communications signal (unless USB

communications is muted), which is useful when connected to an external DSP.

NOTE: Mic/Line input is not routed to Line Out.

• AEC Ref Out — Only the USB Communications signal, summed to mono, is routed to

the Ref output.

• Aux Out — Only the Mic/Line Input signal is routed to the Aux output.

Mixing and Control

Setting appropriate input gain can be done in the Input tab of PCS (see Input Page on

page74). Once the input gain is set for optimal signal levels, mixing and further run-time

level control can be performed from the Mix tab (see Mix Page on page79).
