HDMI audio de-embedding — Embedded HDMI two-channel PCM audio can be
•
extracted to the integrated DSP for processing and mixing.
USB 2x2 audio interface — The USB connection provides a 2x2 channel audio
•
interface with a computer, similar to a standard USB sound card with send and return
audio capability. This allows the MediaPort 300 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 of the soft codec to the MediaPort 300.
• Supports popular software communications platforms including Microsoft Teams,
Zoom, Adobe Connect, BlueJeans, Cisco WebEx, FaceTime, Google Meet,
GoToMeeting, Lifesize Clearsea, Skype, and more.
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 — Provide 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 300 can be set to automatically display a user
supplied image file on the HDMI output whenever no signal is present or on the USB
output if HDCP-protected content is being used and no video can be displayed.
• Aspect ratio control — The aspect ratio of the video output can be controlled by
selecting a fill mode, which provides a full screen output, or a follow mode, which
preserves the original aspect ratio of the input signal.
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 for calibration and setup — The MediaPort 300 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.
Pictures 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 — When HDCP-encrypted content is transmitted to a
•
non-HDCP compliant display, or to the USB output, a full screen green signal is sent to
the display for immediate visual confirmation that protected content cannot be viewed
on that display. An optional black signal or logo can be sent to the USB output in place
of the green signal if desired.
EDID Minder automatically manages EDID communication between connected
•
devices — EDID Minder ensures that the source powers up properly and reliably
outputs content for display.
Front panel USB-C configuration port — Enables easy configuration without having
•
to access the rear panel.
Ethernet monitoring and control — Enables control and proactive monitoring over a
•
LAN, WAN, or the Internet.
