 So I'll be here with a USB. Hi. Hi. How are you? I'm Jeff Ravencraft and I'm the President and Chief Operating Officer of the USB Implementers Forum, which is the industry consortium around here. And a few months ago you announced USB 4. We did two developer conferences, one in Seattle, and we just finished one in Taiwan in November. And this is our new branding strategy for USB 4 technology that's going forward. We're going to have a unified brand and look through all of USB 4. And these are the first images of our new brands. So with Type-C USB 3.1, 2.2, there's been a lot of activity. What's going to happen now with USB 4? USB 4 runs over USB Type-C. So what's going to happen with that? Is it more bandwidth or power? Oh, with USB 4? Yeah. USB 4 allows you to deliver... It's a huge aggregate pipe that delivers DisplayPort, USB 3.2, and PCI Express all over a single pipe. So it's an aggregate pipe that can carry all of those protocols over one pipe. And it all runs over Type-C. What does it mean? You can add PCI Express on there? Yes. What does it do with that fast memory, fast... I'm not a PCI Express guy, but like DisplayPort, for instance. We support DisplayPort today with alt mode for DisplayPort. But going forward with USB 4, you don't need alt mode. It'll just run Display. It'll just tunnel it over USB 4. So every USB 4 device has to have DisplayPort. It doesn't know. No, it doesn't have to have it. But if it hasn't, you can tunnel it over USB 4. Because sometimes it's a little bit challenging to know what device is supporting that. And this has to go into specs. It's no way to force them all to have it. So with USB 4 tunneling DisplayPort, does every USB 4 controller have to have DisplayPort in it? As a host, if you have a display, any other capabilities, you have to support DisplayPort. So the host, a PC host or a tablet host, USB 4 has to support DisplayPort. The device can choose whether it supports it or not. So what's different between USB 3.2 device and USB 4? It sounds like it's the same. Well, it's not the same. USB 3.2 cannot run 40 gigabit per second data-race. It can't tunnel PCI Express, DisplayPort over one tunnel. It's only USB. Now, we support alt mode for DisplayPort. And if alt mode is present, you can run it over a USB Type-C cable and connector. But that's not USB 3.2. That's DisplayPort alt mode. So in the previous generation, it would take up some of the bandwidth. It wouldn't have enough for all three at a certain time with full speed. Well, for Display, the USB performance doesn't really affect Display. So, yeah, but with USB 4, it has the ability to allocate the appropriate bandwidth to support Display, data, PCI, whatever it might be. All right. Any other demos about Display? Yes. So, this is a Samsung video. And the surface is getting power from the monitor over Type-C. And then, that surface can also run a complete OS from the Samsung smartphone. So, it has full PC capability being driven by the phone. So, it's not doing DisplayPort into the laptop, is it? No, it's running just a micro OS. So, it takes the OS in to the OS. So, we'll get the dex in. So, you gotta get a full PC capability from the smartphone over to the USB. And then, this video screen also ships to this monitor over Type-C. Well, how do they do this? It's just data. It's not this Playport. No, it's just data. It's just like working on your PC. But it's sending all the information from the screen. From this phone, yes. Yeah. Not using any DisplayPort type of thing. Yeah, you don't need DisplayPort to run a monitor. Yeah.
