What we have here is a new technology Intersil Techwell is launching here at ISC West called Security Link Over Coax or SLOC. What it is, is it's a combination of analog video and IP high-definition digital video.

Today, we've announced that Sony is the strategic partner for SLOC. They've adopted SLOC. In fact, we're showing a Sony SLOC integrated IP camera here. Basically Sony sees the benefits of having hybrid camera technology that combines analog and IP high-definition video together. And the ability to leverage the existing coax infrastructure out there in the world.

We're very excited to work with them as a strategic partner and an early adopter of SLOC technology.

The benefit of SLOC is that we're taking both analog video and compressed IP digital video, summing them together and sending them out over a single coax cable. So it's basically a modem fi technology. And the benefit to this is that you're able to leverage existing Coax infrastructure which most cabling out there in the world is already coaxial and also extend distances.

Ethernet can go probably about 100m through SLOC over Coax so you can go 300m to 500m.

Another benefit is that we're sending the analog video with the IP video so it's giving you live video capability, no latency, IP video has a compression, IP transmission time in a decompression time. So you're going to get several seconds of latency, whereas the analog video is virtually zero latency. It's real-time video.

One other benefit that we should mention is in terms of redundancy, so if the IP network is flooded or crashes for some reason and the servers go down and you have no more IP network, you have a redundant analog video feed where you're going to be able to keep that camera video going and record that analog video while the IP video goes down, until it comes back online.

So you're basically taking all the best parts of traditional analog CCTV and combining it with all the benefits of the new technology of high-definition IP video.
