What's New in Release 3.14.4?
Release 3.14.4 brings additional streaming functionality through Wowza Cloud to Standalone VGA Grid.
New Streaming Functionality
Live Streaming via Wowza Cloud
Using a simple connection code, the power of Standalone VGA Grid can easily be combined with the flexibility
and worldwide accessibility of the Wowza Streaming Cloud to universally stream from any live video source. See
Stream your video.
Resolved issues
Along with many smaller bugs fixed in release 3.14.4, the following issues have been resolved:
lA blue line appearing on the right side of the captured image when capturing from an SDI source at
720p
lInconsistent/inaccurate status results shown when attempting to extract a subset of a large, multi-track
file
Limitations and known issues
This section includes known issues or limitations that affect functionality or usability and ways that you can
work around these limitations.
Affecting encoding
lEncoding with MPEG-4 sometimes results in poor quality.
Workaround: From the channel's stream setup, increase the video bitrate to improve picture quality.
lVideo bitrate for MJPEG streams are approximately one and a half to two times the configured value.
Workaround: Verify the actual bitrate on the channel's channel status page and adjust until the correct
value is achieved.
lIn multiple source channel layouts, sources cannot overrun the top or left edges of the screen.
Workaround: Avoid using negative values for x and y axis coordinates.
lEncoding is unavailable if a branding logo is placed outside the frame size. (i.e. if the frame is 1024x768
and the logo is placed with an x-axis margin of 1200.)
Workaround:Always keep the branding logo within the frame.
lFor VGAsources only, some wide-mode resolutions are not correctly identified and result in a slightly
squished image (e.g. for a 1360x768 source, the detected resolution may be 1024x768).
Workaround:This issue is related to the video output hardware. Test your source to see if it exhibits the

iv
issue. If possible, avoid using wide-mode for VGAdisplays that exhibit this issue.
lWhen changing a channel's source from a local encoder source to an external encoder source, it's
possible to have an AAC audio encoding bitrate that is higher than the VGAGrid HD Encoder supports.
The resulting stream or recording may be unplayable and you may encounter a warning about variable
audio bitrate.
Workaround: When changing from local to external sources, delete the channel rather than changing
the source(s).Or, if re-using channels, ensure audio encoding bitrate forVGAGrid HD Encoders is set to
no more than 160 kbps.
lRecordings made with encoded streams from VGAGrid HD Encoders, using AACaudio and AVI file
format are not playable via VLC.
Workaround: Use another media player, such as Windows Media Player; choose a different audio codec;
or save recordings as .MP4 or .MOV files.
lSome cameras are sensitive to EDIDs and are not captured at optimal settings. When capturing from
these cameras, the HD signal may be down-sampled by the camera to an SD signal because the Epiphan
system doesn't share the EDID the camera expects for its HD signal.
Workaround:ContactEpiphan customer support for a custom EDID to resolve this issue.
lLimitation: When audio is enabled on an SDIsource where video is already being captured, it takes up
to 15 seconds for the system to detect the audio. Once detected, the audio is properly synchronized
with the video.
Workaround: Start the SDI signal with audio enabled, or check to ensure audio is detected before
streaming or recording.
Affecting streaming
lYou may see video artifacts when creating multiple source layouts where sources are partially
overlapped.
Workaround: Avoid overlapping sources in multiple source channels or disable the Keep Aspect Ratio
parameter.
Affecting recording
lYou may see video artifacts when creating multiple source layouts where sources are partially
overlapped.
Workaround: Avoid overlapping sources in multiple source channels or disable the Keep Aspect Ratio
parameter.
Affecting the web interface
lIt is possible to name two or more channels with the same value. Use of automatic file transfer and UPnP
is unpredictable if this occurs.
Workaround:Ensure each channel has a unique name.
lThe automatic file upload (AFU) file queue shows a maximum of 15 files, Newer 15 and Top of the list
buttons do not work. All files are transfered, even though they are not lists.
Workaround: Wait for the queue to have fewer files in the list.

v
Affecting other areas
lLimitation:Pearl fails to restart after improper shutdown (power cable removed or rapid power cycle).
LED and touch screen blink.
Workaround: Restart Pearl by removing the power cable for 20 seconds, then reattaching the cable and
powering the system back on.

Standalone VGA Grid User Guide Standalone VGA Grid Overview
Standalone VGA Grid Overview
Epiphan's VGAGrid allows you to capture, stream, and record audio and video from a large number of VGA,
DVI, HDMI, composite and component sources. It supports streaming to a large number of viewers using
industry-standard codecs such as H.264 and MPEG-TS. Supporting resolutions between 640×480 and
2048×2048, the VGAGrid is suitable for a broad range of applications.
This versatile system has a variety of options enabling you to create and configure any number of streaming
channels. You can choose to stream (or record) a single channel at once or a configuration of synchronized
channels with picture-in-picture or picture-with-picture multiplexing selections.
The VGAGrid comes in two styles to meet your needs:Networked and Standalone. The Standalone VGA Grid
captures video and audio through internal cards. Depending on the model it has 4 or 6 DVI source ports, 4 or 6
SDI source ports and 4 or 6 S-Video source ports. The latest hardware models(with SDIcapture) also support
HDMI and SDIaudio catpure. Encoding and synchronization of the stream is done locally on the Standalone
VGA Grid. The Networked VGAGrid has no internal capture cards, instead it uses VGAGrid HD Encoders to
capture and encode sources, sending the already encoded stream to the VGAGrid. Using external encoders
means the VGAGrid has less stress on its CPU so it can handle a greater number of inputs. HDMIaudio capture
and SDI video capture are not supported with Networked VGAGrid systems.

Standalone VGA Grid User Guide What's in the Box?
What's in the Box?
The Standalone VGA Grid is a 4U rackmount server with dimensions 522 mm (D) × 430 mm (W) × 176 mm(H)
(20.5” × 16.9” × 6.9”).
Latest Hardware Revision:
Standalone VGA Grid can now capture more HD content than ever before. The newest Standalone VGA Grids
comes with eight or twelve HD inputs (depending on the model). Half the inputs are for capturing from
DVI/HDMI/VGA sources while the other half are for SDI sources. As before there are also 4 or 6 S-Video ports.
With this combination of available input ports and applicable DVI, SDI or S-Videoadapters/converters you can
bring in signals from nearly any source. This hardware upgrade also provides audio capture support for HDMI
and SDI in addition to pre-existing support for 3.5 mm analog audio input ports.
Previous Hardware Revisions
Previous versions of Standalone VGA Grids came with four or six HD inputs (depending on the model). Many,
although not all, previous hardware revisions can support the latest software release.Use the Firmware
Upgrade feature to see if your device is upgradeable. Noteprevious hardware revisions do not support
HDMIaudio capture.

Standalone VGA Grid User Guide Quick Start
Quick Start
This section helps you get up and running quickly with your Standalone VGA Grid.
lStep 1: Physical Setup and Power On
lStep 2: Admin Discovery and Login
lStep 3: Setup the Video Source
lStep 4: Configure the Channel
lStep 5: Testing the Stream
lStep 6: Recording the Stream
Before you get started, make sure you have:
lan HD source (i.e. a computer, a tablet, or a phone)
lthe appropriate cables or adapters to convert the output to DVI or SDI (if needed)
lideally, a network with Dynamic Host Configuration Protocol (DHCP)
la computer with a web browser connected to the same network (this is referred to as the “admin”
computer in the steps below)
loptionally, an audio source such as a microphone or the headphone jack from a laptop . Note that audio
signals sent overHDMI andSDI are supported in the latest hardware revision(s). If you have SDIports,
your system supports HDMIand SDI audio.
These instructions include steps for setting up and configuring audio. Skip these optional steps if
you do not want to configure an audio source at this time.
Step 1: Physical Setup and Power On
Complete the following steps to prepare and power on the system. Refer to the Front and Back Panel View
section for your system to locate the appropriate input ports.

Standalone VGA Grid User Guide Quick Start
6. Wait for the Standalone VGA Grid to complete the power up sequence. The power LED illuminates and
the hard drive LED flashes during start up.
Step 2: Admin Discovery and Login
The Standalone VGA Grid is managed from a web interface. This interface acts as a configuration utility and
system monitor. The first time you access the web interface you will not know the IP address of the system.
The steps below use DNS-based service discovery (a type of zero-configuration networking) to access the
system. Depending on the operating system on your admin computer you may need to install some software
before you can used DNS-based discovery.
This quick start is meant for systems that support DHCP and DNS, however if your system does not
support these mechanisms, refer toConnect to the Admin Interface and Connect via the Epiphan
Discovery Utility for alternative discovery mechanisms. Return to step 3 below you have
completed setting a static IP address for the Standalone VGA Grid.
