Put Video Anywhere

B126 bWhile there’s no explicit limit on the length of how long HDMI video cables can carry high-quality streams, the practical limit is about 50-feet. Beyond that for larger rooms, auditoriums or classes, you need a different approach. The best way is to convert the video stream with audio included into a digital format that can travel over regular old Cat 5 or Cat 6 LAN cables. You will need some special hardware at each end to pull it off, and that’s where Tripp-Lite’s B126-1A1 kit comes in.

The good news is that the $150 B126-1A1 set is not only inexpensive and easy to hide but doesn’t require adding any software. It doesn’t compress the video because the cables can actually handle a gigabit of data per second. In fact, you can think of the kit as an extra-long video cable. There’s a dedicated sender and receiver with an HDMI port at one end and an RJ-45 LAN port at the other. Both require power from an included AC adapter and include brackets for mounting the devices on a rack.

Able to support 24-bit color, 3-D and eight-channel audio, setting the B126-1A1 up literally takes a minute. Plug the sender in to the source material, connect the LAN cable and then plug the receiver in to the display. Each power plug can be screwed into the B126-1A1 device so that it doesn’t accidentally get loose at exactly the wrong moment.

B126 aDon’t get worried if after powering the devices up, the system doesn’t work because there’s an equalization dial that might need to be adjusted. Calibrated from 0 to 7. The only way to figure out the right setting is trial and error.

Using the B126-1A1 pair with a variety of Cat-6 LAN cables, I was able to move a 1080-p signal for as far as 180-feet. A little farther and the signal starts to lose frames and show odd artifacts. That’s slightly farther than the company’s 150-foot spec. According to Tripp-Lite, the system can move an interlaced signal 200-feet. If that’s not enough, the company sells B126-110 repeaters that roughly double the extender’s range and you can use up to three without degrading the signal.

If you’re requirements aren’t that demanding, Tripp-Lite’s B126-1A0 set uses USB power, costs about $70 and worked well up to about 150-feet. Either way, using HDMI over Cat-6 cables lets you to put video displays exactly where you want them without having to think about how far HDMI cables can reach.

Welcome to the Next-Gen Teacher Conference

PNG 72 dpi (RGB)-11_ GROUP Bundle_Lifestyle_Mics_ Clean Empty Room Set-upThe next time you put the sign-up sheet on your classroom door for a round of parent-teacher conferences just might be your last. That’s because the latest video conferencing gear can bring teachers and parents together while allowing them to be in separate locations. The Lifesize Group kit includes an HD video camera with a wide 90-degree field of view that uses the latest H.264 codec with video scaling for high quality streaming. This allows everyone in the room to be seen or you can zoom in on a single head with the auto-focus 10X optical lens for a one-on-one video chat. Its remote can control the camera’s panning and tilting as well as its zooming.

In addition to a connection hub, the Group kit has a speakerphone with 4 microphones for lifelike audio. By using beamforming technology, participants as far as 20-feet from the speakerphone can be heard. The speakerphone’s display shows that you’re connected.

At $1,000, it is the videoconference bargain of the year, and adding a second microphone brings the total cost to $1,250. Either way, it’s a small fraction of what similar gear from Cisco, Polycom or Vaddio cost and the Group kit is easier to set up and use. All Lifesize group byou’ll need is a connected computer, which can be a mobile phone, a tablet or a notebook. 

For schools worried about extra monthly service bills for video-conferences, the Group is agnostic as to what service it uses and works just as well with free ones as with ones that charge. It can be set up on Skype, Lync, Google+, WebEx, Vydo, Zoom and others so that you can connect with any parent, anywhere without leaving the school.


Freebee Friday: Selfie Assignments

Recap_scrolling_dashboard-300x281If a thoughtful, poised answer counts for as much as elegant writing, then Swivl’s ReCap should catch on quickly. The app works directly in iOS systems and there’s a browser based version for PCs, Chrome and Android machines. It lets a teacher ask a typed, audio or video question of the class that then gets recorded replies and answers sent back to the teacher for analysis and grading. A daily review reel consolidates all the answers to the question as soon as three have been received, making viewing a snap. It’s a beta at the moment but the company will smooth off some of its rough edges over the coming months, but they plan for it to always be free.

Video All the Time

Vp71xd compositeThe essence of digital signage is to use a video monitor to show teachers and students everything they need to know, from today’s lunch menu to escape directions during an emergency. Videotel’s VP71XD can feed it with HD video and sound. In addition to media-playing software, device has an HDMI and RCA outputs, comes with a remote control and scheduling software. It costs $382.

Let There be (the Right) Light

ZylightOften the difference between cheesy and professional-looking video is lighting, and Zylight’s Newz compact on-camera light can illuminate the situation. It’s based on LED technology so it doesn’t drain batteries quickly and the lighting element may never need to be changed. The $429 light can attach to a camera, has an articulated arm and barn doors for cropping the beam to just where it needs to be. The best part is that the light’s 60-degree beam is not only dimmable, but can be set to a color temperature of anything between 3,200K for indoor sequences or 5,600K for daylight shooting.

Five Easy Video Editors

Video editors compositeTurning a series of clips into cogent videos is a skill that all kids need to learn, but which platform is right for 21-st century story telling? I think that kids need to master the ability to edit video on all the major platforms in use at schools, from PCs and Macs to iPads, Androids and Chromebooks. That way they won’t be caught short on video skills.

Not only can you use any of these apps to create visual repots on science and English lessons but enhance each child’s story-telling skills. Next stop, Hollywood.

Windows Movie Maker

MoviemakerOnce a part of every Windows computer’s software, Movie Maker is now relegated to a free download that anyone can add to their system. Version 12 still uses a timeline for creating a video and works with all recent versions of Windows. In addition to adding and rearranging clips, you can work with transitions and even get rid of camera shake. When you’re done you can share the movie online or add it to a Web site for the world to see.

KineMaster Pro

KinemasterAndroid tablets can now make full movies with KineMaster Pro. The center of attention is its multi-track timeline where you can slip in videos and edit them on a frame-by-frame basis as well as add audio tracks and transitions. Rather than having to use a mouse, everything can be manipulated by a finger or stylus for things like adding titles. The completed movie can be shared via YouTube, Facebook, Google+ and Dropbox.



IPhone5s_iPadAir_iMac27_MBA13_iMovieThe iMovie app that comes with Macs puts the emphasis on simple movie-making with a few frills, like Apple’s excellent online how-to section. One of the rare video editing programs that can handle 4K resolution, iMovie has templates that you just type in a name and drop in the clips. You can take that to a new level with the ability to use iPad vids as well as ones from a camcorder or phone.


We Video

WevideoDespite being basic and not exactly high-performance systems, Chromebooks are surprisingly good at editing videos. WeVideo lets you use a storyboard approach for a mini-movie or the more traditional timeline. Just drag a variety of files into position to be integrated and the app does the rest. If you don’t have what you need, the program includes 100 royalty-free effects and sound clips as well as the ability to use slow motion or time lapse effects. You can have kids team up to make movies and the free version allows up to 5-minutes of final movie time. The K-12 package costs $249 a year for a classroom of up to 50 students and allows each student to save an hour a month of videos and 5GB of online storage space.


Pinnacle Studio Pro

Studio proVideo editing on iPads takes a big step forward with Pinnacle’s Studio and Studio Pro apps. The basic Studio software is free and lets users quickly create basic videos in a timeline format, while the $15 Pro version adds the ability to edit in up to 4K resolutions and save the results online.



Freebee Friday: See and Say

FoxDen_ScreenShotSmall groups of students and teachers can now video chat online or free with ReadyTalk’s FoxDen collaboration platform. The software is still in development, but you can use it to provide high-quality real-time interaction from within the Chrome browser as well as any Android device, iPhone or iPad. It can connect up to 10 users.


From Video to WiFi

Actiontec mocaWhat are the two things that old schools have in common? They are often really awful places to deploy WiFi and they have a disused coaxial network that once distributed analog video and reaches every classroom. Actiontec’s latest products can help use the latter to conquer the former in schools by running data over the coaxial network and then distribute it via a WiFi extender. The WCB6200Q Wireless Network Extender uses the latest Multimedia Over Coax Alliance’s MOCA 2.0 spec to grab data off of a coaxial line and send it out as a pure 802.11ac WiFi signal. The key is that the WCB6200Q is not a router, but is like a powerline extender, except that instead of the facility’s power wires, the data rides on coaxial cables. While the WCB6200Q also has a pair of wired ECB6200Ethernet ports, the WCB6240Q has four. It has 4X4 capabilities, uses the latest beamforming techniques and Mu-MIMO technology to boost its output. With the ability to give video the priority for delivery, it’ll be hard to overwhelm the equipment. You’ll also need to plug Actiontec’s ECB6200 Network Adapter into your router or a LAN switch to send the data out on the coaxial line.

Video That’s Permanent

Lifesize Cloud Amplify - Embargo until 7-21-15 8am ETVideo conferences with parents, training sessions and even lessons for kids stuck at home sick can now be archived with Lifesize’s Cloud Amplify online service. Any participant in a conference can save the whole video chat with a single click and retain 15 hours of video. There’s a free trial to give it a test drive.



Digital Video Made Easier

Replacing analog video lines with a school’s networking cabling can not only cut costs and improve quality, but nobody said that the transition to using a network to distribute video throughout the campus was going to be easy. The latest gear can help with ways to put video in every classroom.

Startech hdmi with appStarTech’s latest HDMI over IP kit can not only distribute video over plain old network cabling, but with the company’s new apps, you can control it from a phone or tablet. The HDMI kit costs $430 and can be used with the company’s free StarTech.com Video Switching and Wall Control apps for iPhones, iPads and Android systems. At the touch of a finger, you can set up, control and choose among multimedia options as long as the tablet or phone is on the same network as the switching gear.

Tripp lite BHDBTKSILR-FRONT-LDistributing digital video often opens a can of worms because the signal needs to be periodically boosted. That’s where Tripp Lite’s family of HDBaseT extenders comes in. They support up to 4K resolutions and a variety of audio effects, like DTS-HD and Dolby TrueHD. The devices can transmit uncompressed HDMI audio and video over roughly 2,000-feet of network cabling.
