DESCRIPTION

The Extron MediaPort 200 is an HDMI to USB bridge for integrating pro AV sources or systems with software codec conferencing applications. It works seamlessly with a computer using generic USB video and audio drivers. The MediaPort® features an HDMI input with HDCP-compliant loop through, accepts signals up to 1920x1200, and scales video to a USB 2.0 output. Audio features include program and mic inputs, HDMI audio de‑embedding, and USB bidirectional audio, plus AEC reference and line level outputs. The MediaPort 200 also includes DSP with EQ, filters, mixing, dynamics, and ducking. This allows the MediaPort 200 to serve as a complete soft codec interface, with the added flexibility of integrating into larger hardware codec or DSP systems. The MediaPort 200 enables versatile integration of conferencing computers into pro AV designs.

The MediaPort 200 bridges the gap between simple Webcam-to-computer solutions and traditional hardware videoconferencing systems. For small meeting spaces with just a computer and display, the MediaPort 200 is ideal for enhancing audio and video quality by adding support for professional-grade equipment such as videoconferencing PTZ cameras, boundary microphones, and sound reinforcement systems.

In boardrooms and large conference rooms, the MediaPort 200 easily integrates a conferencing computer into a fully equipped AV system with a hardware codec, video distribution and processing, control, DSP, microphones, and full sound reinforcement. In addition to conferencing, the connected personal computer can be used with a software application to record meeting sessions, presentations, or lectures.

Streamlined Installation
The MediaPort 200 connects to Windows® or Mac®-based computers with USB plug-and-play simplicity, using industry standard UVC - USB Video Class and UAC - USB Audio Class drivers. It can be used with popular software and cloud-based communications platforms including Microsoft® Skype®/Skype® for Business, Adobe® Connect™, BlueJeans, Cisco® WebEx®, Citrix® GoToMeeting™, Zoom, and more.

With the buffered HDMI input loop-through, the MediaPort 200 also works in conjunction with hardware codec solutions from manufacturers such as Polycom®, Cisco, and LifeSize® to augment communications capabilities in established videoconferencing environments. Additionally, the HDMI input and loop-through are HDCP-compliant, enabling straightforward integration into systems for passing encrypted content from a source to a display.

Optimal Video Processing for Soft Codecs
The MediaPort 200 accepts resolutions up to 1080p/60 and 1920x1200, and provides high performance deinterlacing of interlaced signals up to 1080i. To ensure the HDMI source is presented with the highest possible image quality to a soft codec, the MediaPort 200 incorporates video processing technology, specifically engineered for optimized image scaling and frame rate conversion that preserves detail and legibility of source content. Output resolutions range from 320x180 to 1080p/15, and are dynamically configured by the software codec as it responds to real-time CPU usage and bandwidth conditions between near-end and far-end locations. The video output is delivered as an MJPEG-encoded stream over USB 2.0.

The MediaPort 200 is a fully featured video processor with many of the core integration features common to Extron scalers, including aspect ratio control, internal test patterns, Auto-Image™, and Auto Input Memory. It can also display a user-supplied logo image whenever no signal is present at the HDMI input.

Versatile Audio Integration with DSP
The MediaPort 200 accepts a microphone input and program sources as analog audio and de‑embedded HDMI two-channel audio. The USB connection provides a 4x2 channel audio interface with a personal computer, similar to a standard USB sound card with send and return audio capability. This allows the MediaPort 200 to send a two-channel mix of the microphone, analog program, HDMI audio, and USB playback audio to the computer. The interface also allows the MediaPort 200 to receive four audio channels from the computer, including program audio plus two-channel communication audio from the soft codec’s far-end, completely eliminating the need for any analog audio connections to the personal computer.

The audio DSP in the MediaPort 200 is designed with audio capabilities beyond those found in hardware codec-based audio systems. Essential digital audio processing tools including gain, mixing, parametric EQ, filtering, dynamics, and ducking are available. The DSP can be used to optimize microphone and program source signals, as well as outgoing signals bound for the personal computer, sound reinforcement systems, or outboard DSPs. The MediaPort 200 also delivers far-end audio as a dedicated AEC reference output to an AEC-equipped DSP, such as the DMP 128 C. Using the AEC reference signal, a DMP 128 C can provide distributed AEC processing for several microphones, to ensure that far-end conferencing participants always receive clear, echo-free audio from the near-end AV system.

Multiple Options for Control and Operation
The MediaPort 200 features front panel controls with an LCD menu display for quick access to system settings. Remote configuration and control are available via Ethernet, USB, and RS‑232. The MediaPort 200 can be configured using Extron’s PCS - Product Configuration Software with a user-friendly GUI that is very easy to navigate. This software application allows for expedited setup and commissioning, real-time operation and monitoring, firmware updates, plus full configuration of the DSP and its audio processing tools.

In addition to configuration and control capabilities, the MediaPort 200 includes front panel LED indicators that provide comprehensive visual feedback for HDMI input and loop-through signal presence, HDCP status, and USB signal status for host, video, and bidirectional audio.

The MediaPort 200 includes two digital input and two digital output ports which facilitate triggering mic activation and muting via contact closure, as well as illumination of mic status LEDs.

Convenient Under-Table and Surface Mounting
The MediaPort 200 is housed in a compact 1U, half rack width enclosure that can be installed virtually anywhere, including inconspicuous placement underneath a conference table, inside a credenza, or in a lectern. Extron UTS Series and MBU 123 mounting hardware are available separately to facilitate under-table mounting. Passive convection cooling ensures silent operation.
