DVEO's DOZERbox Sends Error-Free Streams on the Internet
[Note: This sponsored interview was recorded at NAB 2014.]
Turn the public internet into a managed network. At the 2014 NAB conference, DVEO gave an impressive demonstration of how broadcasters can use the DOZERbox to send video streams long distances online with fantastic results. The demo put a stream that wasn't using DOZERbox side-by-side with one that was. The non-DOZERbox stream showed 30 percent packet loss -- "completely unusable," said Streaming Media contributor Shawn Lam -- while the stream sent with DOZERbox looked great.
After learning about the tunneling and packet recovery that makes DOZERbox work, Lam asked who the intended client is.
"Anybody doing live delivery," said Scott Grizzle, broadcast and streaming product manager at DVEO. "It’s distribution companies, encoders to a CDN. So that way, you know, there’s a question where you’re at, you want to make sure your feed gets to a CDN, perfect fit. Again, customers who need to transport daily media from one location to another location real-time in low latency or even TV channels. You know, the whole IPTV mode. You can get it to a distribution point over the rough areas and you can distribute from there."

Shawn: It’s Shawn Lam here for Streaming Media. I’m joined with Scott Grizzle from DVEO. We’re going to be talking today about the DOZERbox. What is it?
Scott: The DOZERbox is a guaranteed video delivery system. So we can take in IP streams, encode it to either send or receiver, or transmitter to receiver, and guarantee delivery. You can drop the internet. That internet drop of 30 percent without DOZER, and this one’s with DOZER. So you can see packet recovery, but also you could treat public internet like a managed network, so you hit less pops. So you set it upright, you’re going to have to reduce latency. We have customers in Cameroon who are getting feeds from Greece. They’re routed by internet, they have guaranteed delivery and they are exceptional. We have customers in Florida getting stuff from Russia, and things like that.
Shawn: Okay. That’s a dramatic difference. This is obviously completely unusable and this looks great.
Shawn: How does the technology work?
Scott: It is tunneling and, again, packet recovery. So when the video’s out there it asks for a new packet and out of the buffer. So since this is real small overhead, not like FEC, the timing, and it doesn’t send everything, it just sends what it needs. And so say, “This packet is missing, please send," boom, it’s there.
Shawn: Okay. And who’s the DOZER for?
Scott: Anybody doing live delivery. It’s distribution companies, encoders to a CDN. So that way, you know, there’s a question where you’re at, you want to make sure your feed gets to a CDN, perfect fit. Again, customers who need to transport daily media from one location to another location real-time in low latency or even TV channels. You know, the whole IPTV mode. You can get it to a distribution point over the rough areas and you can distribute from there.
Shawn: Okay. You guys also make the Brutus piece of hardware there. How does that integrate with that hardware?
Scott: Well, actually, the DOZER can be installed on any of our encoders. It is, the Brutus V, is a massive encoder that I designed to do 120 SD, 47 20s or 30 1080p's. So whatever you want to bring in, you can kick out. With a DOZER on there, you can make sure all those are going to any CDN of your choice, or that has the receive side or to another location, maybe for, you know, again, other locations.
Shawn: Yeah. That’s a lot of simultaneous inputs.
Shawn: Who’s going to be using that type of a device?
Scott: Cable telcos. IPTV, anything OTT. It’s going to be in the cloud. We have some people have, you know, the studios all over the world, they’re uplinking, sending it out to another location. They’re able to take that and actually use our decoder, the D-streamer, and bring those back to their HD-SDI solution. So they can actually bring IP in and distribute for public news. Or vice versa.
Shawn: So Scott, you have an Ad Serter. How does that integrate in with the Brutus V?
Scott: Well, the Ad Serter is a video overlay system that can do ad insertion, graphics and everything else. You can actually take the Ad Serter, take the IP feed out, feed it into the Brutus V, so now that one can be transcoded into, again, 120 SD or 40. There’s a EAS system built into it. So say you are watching your Netflix or something else on there and all of a sudden, or a Roku channel, and a tornado’s coming or a hurricane and they need to do, you know, the emergency alert or an Amber Alert. This can kick off those alert systems also. So now you’re not stranded like, you know, it’d be different than traditional TV. We don’t have the services. Now IPTV can have the same services as traditional TV.
Shawn: Okay. So this can be used on a Roku box application. What about in an airport environment?
Scott: Yes. I mean, so you can be watching TV. Airports can be using this to do the localized, you know, “This is sponsored by LG, Samsung,” so the sponsorship stuff on there. Anything that you have a closed caption audience, you can do different delivery mechanisms like that. Because it’s IP, or you can go about ASI or SDI, however you want to go, and you can distribute out through modulators or, again, or to a set-top box.
Shawn: Well, thank you very much, Scott, for an update from the DVEO booth here. We’re at NAB 2014. Thank you very much.
