New Duke Crestron Rep

Leave a Comment Written by Jack D'Ardenne

Some Duke AV folks recently met with Crestron’s new Regional Education Market Manager, Ryan Berndt.  He will be replacing Brian Montini.  Ryan will be Duke’s Crestron rep from now on.

During our meeting with Ryan and Brian we learned of a new Crestron wireless content sharing technology device that they are working on.  It will allow content sharing over the network to a small footprint box that has HDMI out similar to an Apple TV.  They are claiming that several operating systems (Windows, Mac, iOS and Android OS) will be supported.  That is all we know for now but we are very anxious to learn more.

makethumbnail.ashxI don’t know much about it this camera but it is nice to see more USB PTZ options.  It claims to work with built-in OS drivers so nothing to install.  It also claims to work with all major web conferencing apps including Skype and Cisco Jabber (Movi).

If you have an existing HD videoconferencing room or a Telepresence System, you very likely have the ability to use it as a production facility and connect to places like CNN, CBS and ESPN to participate in interviews or deliver your message.

Getting your company’s spokespersons and brand ambassadors on the right television programs at the right time with the right message can be a major challenge due to physical travel, pre-scheduling and cost constraints.

MASERGY’s Business to Broadcast Exchange (B2BC) gives enterprises the power to easily and seamlessly transform their Telepresence/HD video rooms into insert studios that can be instantly and broadly accessible by any television network or program. The result—no media opportunities missed, and all messages communicated.

FEATURES

  • Guaranteed network QoS, delivered through a private, fully secured global IP network
  • Ultra-low latency from anywhere in the world
  • Seamless interfaces with leading HD media switching centers

BENEFITS

  • Leverage existing investment in Telepresence/HD videoconferencing systems
  • Enable full HD-quality transmission to any broadcast production studio
  • Capitalize on media appearance opportunities on short notice

Epson MegaPlex MG-850HD HD 720p All-in-One Projector w/ Apple-Device Dock

OIT-ITS purchased the Epson MG-850HD projector a few months ago with the hopes of using it paired with an Apple iOS device (iPhone, iPad or iPod Touch) to do video conferencing.  The projector features a charging dock connector that supports any of the current Apple iOS devices.  Unfortunately, after some testing we found out that the projector does not support any kind of mirroring from a connected iOS device.  However, it does support the playback of any photos, music and videos that are currently on an iOS device that is plugged into the projector’s dock connector.  The playback of the photos, music and videos is done using a basic user controllable interface on the projector.

Since the projector does feature an HDMI connection we decided to throw an Apple TV into the mix so we could mirror our iOS device’s screen to the projector.  This worked perfectly mirroring our iOS’s screen to the Apple TV which was connected to the projector via HDMI.  This could be done with any projector that has HDMI but we were impressed with the video and audio quality of the Epson.  For more specifics on the projector check out the Epson MG-850HD product page.

Need a cheap HDMI switcher?

We recently purchased this little guy from monoprice.com for $10.15.  The HDMI switch features 3 inputs and 1 output, and does not require a power source.  It automatically switches inputs when a device is powered up or can be switched manually using a button on it.  The switcher supports all current formats and supports HDCP pass-through.  This unit is so small it can pretty much fit in the palm of your hand.  It could easily be mounted on the back of a display for easy hiding if desired.

Cisco’s New Video Conferencing System, the SX20

Leave a Comment Written by Jack D'Ardenne

ITS recently received a demo unit of Cisco’s new video conferencing system, the SX20.  The SX20 was released early this year and offers a smaller footprint than the c20 but is very comparable otherwise with a few feature differences.

The SX20 does offer a paid upgrade option for multisite which the C20 does not.  This allows the SX20 to add three remote participants to a call without the need of any kind of video conferencing bridging services.  However, with Duke’s video conferencing infrastructure users have free access to Duke’s virtual conference rooms which offer the same functionality without the need for the paid multisite upgrade.

Both the C20 and SX20 use the same proprietary Cisco microphones but the SX20 has two echo cancelers while the C20 has one.  The SX20 uses a proprietary HDMI/RS-232 cable.  On the C20 HDMI/RS-232 are separate cables and allow for easier integration into a conferencing room especially when longer cable runs are needed.  This will make integrating the SX20 into a conferencing room more difficult.

The SX20 can share content at up to 1080p15 while the C20 supports WXGAp15(1280×768).  However, to support sending 1080p resolutions the premium resolution paid upgrade option is required.

The C20 and SX20 are both great video conferencing systems for basic room and office installations, and cart solutions.  They even work great as portable room systems.  If you have any questions about either of these or any other video conferencing system please contact oit-its-info@duke.edu and we be happy to talk with you about them.

Acer Debuts World’s First 1080p Hybrid LED-Laser Projector

Acer just announced a new 1080P projector that features a hybrid laser-LED light technology.  The new light technology not only offers better color saturation and energy efficiency but also longer light light-source life and instant on/off.  The only downside to the projector is only offers 1,500 lumens.

LED light technology in projectors is becoming more and more popular and it will be exciting to see how the technology changes features and functionality in upcoming projectors.

Airplay Mirroring to an Apple TV on Duke’s Network

I know there were some emails that bounced around on the DDMC mailing list some time ago about folks having issues getting Apple’s Airplay Mirroring to work on Duke’s network.  I recently reached out to OIT Networking to see if and how this could work.  They had already received some requests for it and started configuring Duke’s wireless network to allow traffic for Apple’s Bonjour protocol.  This will not work if any device is connected to the Duke network via ethernet.   All Airplay Mirroring devices trying to communicate with an Apple TV will need to be on the same wireless subnet.  Most buildings across campus are on their own wireless subnets so this should not be a problem.  Also, having devices only seeable on the same subnet will reduce the number of Apple TVs seen in the share list.
I would recommend a naming convention that makes sense for your Apple TVs.  Protecting them with a simple password may not be a bad idea either.  I know some schools have their own networks and/or firewalls in place so you may need to work directly with your school’s networking team to get this up and running.  If you have any issues getting this to work, OIT Networking has asked that you submit an OIT Help Desk ticket for support.
Please share your experiences using Airplay Mirroring to an Apple TV with the DDMC mailing list.   I think this has great potential for specific classroom and portable applications.  And because it’s free and built-in to Apple’s soon to be released Mountain Lion, it will be that much more accessible and handy.

Two Promising Accessories for Mobile and Class Capture

May2nd
2012
3 Comments Written by Todd Stabley

We recently came across two interesting and (fairly) inexpensive accessories that may be of interest to those of you involved in or supporting classroom and mobile capture.

The first is the Swivl (http://www.swivl.com/), a mount for iPhones, iPod Touches, Go Pros and other portable cameras by way of the included standard tripod mount. We haven’t had the opportunity to test this device yet, but are excited by the possibilities it could offer for bringing class capture to rooms that lack expensive A/V infrastructure, or to support enhanced video quality for those using DukeCapture Mobile in non-classroom locations.

The Swivl

The Swivl lets you remotely operate your camera, has a built in microphone, and includes the ability to automatically track yourself (or whomever you’re recording). It rotates 360 degrees horizontally, +10 / -20 degrees vertically and runs on standard AA and AAA batteries (or optional AC adapter), and has a range of 10 meters. The Swivl costs $179.00. If any of you get a chance to take a closer look at this device or to test it, please keep us posted how things go.

Swivl Demo

A second device that can substantially increase video quality for your DukeCapture Mobile recordings is the MicroPro by Litepanels (http://www.litepanels.com/language/pages/micropro.php).  OIT ITS recently acquired one of these, and it’s performed well in our testing.

The MicroPro by Litepanels

This small form factor LED light is essentially a tiny professional diffuser light. It operates on 4 AA batteries (seem to last a good while) includes a 3-piece gel kit, a hotshoe mount, a case, and a dimmer dial that takes you all the way from zero to way too bright at the highest setting if the light is placed within a couple feet of your subject. With the dial somewhere in the middle, though, you can finally leave that murky webcam video we’ve all come to expect far behind and create much more professional looking images that will set your captures apart.

The main downsides of the MicroPro are its cost (at $275.00 it’s not exactly cheap), and the fact that it doesn’t come with a built-in mount for attaching it to your computer monitor. Certainly the creative folks among you will find some way to do this, however, and even if you can’t, you can get good results simply by setting it at an angle against something on a desk and pointing it toward your subject.  It does have a slightly cheap plastic feel to it (especially for the price), but don’t let that deter you–it’s a very powerful light for its size.  If any of you want to give this a look, please give us a shout.
