And as we pointed out before the Niagara 2120 encoder from ViewCast is the heart of this thing and to adapt it for increased mobility Go-Live came up with a modification for the original power supply. What did you do for that?
Yes Bennett, Niagara 2120 is basically supplied with DC. It’s comes with a AC to DC power supply but what we’ve done is fit the kit with a couple of standard Anton Bauer-type batteries which are fitted with a hotswap so basically you have standard batteries that every broadcaster has in their backpack that you can change while you’re working to basically feed the kit with fresh batteries and make it run for as long as you need. With a basic set up of 290W-an-hour batteries the kit will work up to nine hours without a charge. [Timestamp: 6:29]

And those Anton Bauer batteries aren’t going to be new or foreign to anybody who’s been in the broadcasting and field production, and the whole theme of this kit is to take proven field power technology, encoding, and transmission and put it all together in a new combination to suit wireless internet video streaming from anywhere.
Yeah, you can basically always pack it light. You can use a smaller battery if you just need a short time of webcasting so… [Timestamp: 6:56]

And you just become the remote truck yourself.
Yeah.

Now on larger events since the…a video signal is a video signal you can connect, say, a switcher AUX output to the 2120 and take a video feed and stream it for a church service or a sporting event with multiple camera coverage. And the same simple operation that makes it reliable for pros out in the field can also make it, say, useful for maybe less experienced volunteer tech people on a church crew.
Yeah, well the kit is meant primarily for a one-man installations to make it easy and fast set up but because the core appliance is the Niagara 2120 and the 2120 basically takes any form of the analog video you want to feed it you can just log it in at the end of your signal chain and use it to broadcast from the studio from a video switcher of whatever feed you use, yeah. [Timestamp: 7:52]

Now for the audio feed would you need to have external processing, say, compression or something out boarded to be able to take a feed like that?
Well basically the kit has a few audio options and a few video options. All you need to do being that feature is available on the Niagara 2120 and we’ve made the adjustments for it to be available on the…also on the Go-Live kit you just have to log into your device from a remote computer and choose whichever input you want whether it’s balanced, audio unbalanced, audio component, video, composite video, or S-Video or with everything and just transmit that the same as you would put the monitor there. It just pushes it forward. [Timestamp: 8:31]

And you’ve got a USB port on the 2120 encoder so you can connect straight in just in case you have a last-minute, say, change of parameters or you can just set it up ahead of time and when you get to the site it remembers that and you just power up and go.
Exactly. First of all, you can have yourself set up before you get to the location. You can also on location connect to the machine a monitor and an interface and choose whatever options you would like to choose and you can also log in from afar from a internet browser in…in the headquarters and change the inputs, change the features, change the service, change the quality—whatever you want. [Timestamp: 9:11]

You were telling me before about some of the live events that Go-Live does and that can be just about anything. Have you had any particularly notable events that you’ve used the kit to cover lately?
Well basically the kit is used for all sorts of various events but because it’s simple and very fast setup we mainly use it for emergency ENG. Lately we’ve had a big forest fire in the Carmel Mountain in Israel which we’ve had the need to setup and transmit a live video from event and do it fast so we just setup with the kit. I would just like to add one thing that I think that is the basic trend for broadcasters today, I think that fast setups and wide distributions are the main features needed today because I think that most news agencies and most content owners would prefer to have their video available fast rather than to choose a complex production environment that the moving van would supply and if you need to have wide distribution all over Israel, Israel is small but in other countries you can’t network the whole country with an ability to transmit live within say up to half an hour from the event if you’re using an OB van. If you’re using a kit, a small backpack kit, that could be carried by every broadcaster, every camera holder, every reporter on location to just setup and transmit very fast—I think that’s where the market’s going. That’s where the contents going. [Timestamp: 10:4]

Well that certainly appears to be where it’s all going. All right it’s Eitan Ortal with Go-Live and the new kit built around the Niagara 2120 from ViewCast. Eitan, thanks for being with us.
Thank you very much for the opportunity to speak to you Bennett.
