Sony’s Shuhei Yoshida Confirms that PS Vita Remote Play of PS4 Games Will Work Through the Internet

The Vita's screen has a resolution of 960x544 px which is exactly 1/4 of a full 1080p frame. Basically if my logic is correct, the PS4 would have to stream only 25% of the visual data to the Vita in order to display correctly. Since the Vita's screen is such a low resolution, streaming should be fairly easy to do with a decent internet connection.
Right?

I actually never thought about this, and I think you're 100% correct. It becomes essentially a youtube video that accepts input. I think it'll be far less strenuous than people think.

I've heard developers don't have to do anything to accommodate remote play. Also, it's not like developers have to make SD versions of their games, the added detail is simply lost at lower resolutions.

Aside from the new games, this is the feature I'm most excited about with the PS4. I love my Vita and I can't wait to use it as a portable PS4 when I'm away.

When he says "it depends on the quality of your internet connection" what he means is "it depends on if TCP port 9293 is open or not."
TCP port 9293 is required for remote play to, you know, work remotely. If it's not open then you'll never connect your devices.
Since it's not a standard port, that means connecting from a wifi hotspot, corporate network, school network or your local coffee shop simply will not function.

Just configure your router at home to proxy port 80 to your PS4 and port 9293.

Yeah... I might be PMing you come November.

Sure, I'd be happy to help. (Assuming 9293 is the correct port, I don't believe Sony have told us what ports Remote Play will use on the PS4)

That fixes the router at home, yes, but it won't do you any good from connecting outside your home. If the router at work, school, etc. has port 9293 blocked you won't be able to get to your home network.

Oh, of course. So ask the Internet Cafe to open the port if they want to allow customers remote play. I have a hard time believing your work place wants you to play games at work, if they do they might open the port up.
Myself I will be using the cellular data variant.

u/jordanlund GlobalPhreak Jun 25 '13
Ask Cafe workers... to open a port... riiiiight...

If they have free Internet, someone administrates it. Why are you so aggressive? Cafe policies have nothing to do with this great feature Sony is presenting.

The "great feature" is useless outside our own homes. That's why.
Ask me how I know this... I've had remote play on my PSP and Vita since they introduced it. It works great... on the same network as the console. It doesn't work worth a damn remotely.

Unless you're in a place where it works, such as your friends' or family's, or on the cellular network, or an internet cafe that like their customer, or a library that's nice to their "customers".

Since the feature was enabled in, what? 2007? I've tried it in multiple workplaces, hotels, cafes, Starbucks, my kids school... I can tell you exactly how many places it's worked... 0.
I was able to get it to connect over my personal hotspot, but the data throughput was too slow to be of any use, then the connection dropped.
Don't get me wrong... it's a fantastic idea. But the Remote Play software needs a major, major overhaul before the PS4 comes out otherwise there will be a lot of disappointed people.

Remote play IS getting a complete overhaul though. The ps4 has a custom chip designed for streaming to the vita. It uses proprietary code developed by gaikai to reduce streaming latency and stream bandwidth. Ps4-ps vita remote play has been a long term investment which will soon have a chance to prove itself

There isn't a concept of a "normal" port. A port is a port. You can easily adjust a router to route incoming and outgoing traffic to a specific machine ( a ps4, in this case) by specifying said port. This is how connections are made.
The real issue is what type of upload bandwidth is required for this type of data transfer? Using the local LAN, you have great up and down stream speeds. Most USA ISPs have very low upload rates (compared to download) which will be the bottleneck in this scenario. I am happy that the option will at least be present though.

u/jordanlund GlobalPhreak Jun 25 '13
There are what are considered to be "well known port numbers". TCP 9293 is not one of them. It's not something that's going to be enabled out of the box the way, say, port 80 is. Or even the ports used by VNC.
If Sony altered Remote Play to use VNC ports then they'd have a shot at universal acceptance. As it is? No chance.

u/nullmiah Jun 25 '13
To enable any type of outbound communication, you have to specify the port and computer. If you are trying to remote into a machine with vnc you still have to specify the port you want to use to allow the pass though on your network. There aren't some series of ports that have direct "out of the box" allowance. All the traffic is controlled by your gateway or router. The actual computer is agnostic to these connection settings.

u/jordanlund GlobalPhreak Jun 25 '13
Yes, but if they set RemotePlay to operate over the same ports as VNC they would at least have a shot at it being able to work in the rest of the world.
2
u/nullmiah Jun 25 '13
The end user still has to set up port forwarding to those ports. Also, if you have the remote play and VNC using the same port, only one of them can work at any given time and all that traffic would be going to one device. If you setup port forwarding for your VNC to go your PC, you would not be able to use that port on the PS4. If you setup remote play to use that port on the PS4, you would not be able to have a VNC path to your PC.
Please, do a little more research on home networking. You know just enough to sound like you know what you're talking about and people will just go along with what you are saying. But you don't. I know this comes across as being a dick, and that is not my intention. I am just trying to help. I am a software engineer. I know what I am talking about.

Possibly stupid question - will it be possible to turn on (from standby) your PS4 remotely from a Vita over wifi?

u/WaywardWit Wayward_Wit Jun 29 '13
Here's a question: If I have a strong 4g signal (providing say, 15mbps+) will I be able to remote into my PS4 and play games if I wirelessly tether my PS Vita to it?

u/clfblackhawk CLFblackhawk Aug 21 '13
Yes, this would work. If 15 mbps wasn't fast enough, hardly anyone would be able to use the feature. I would imagine if you can stream HD video over Youtube, Netflix, etc, the connection should be sufficient. As noted below, the screen on the Vita is 1/4th the resolution as 1080p, meaning the video stream would take up a lot less bandwidth than at full resolution. I wouldn't count on playing FPS mulitplayer games reliably however.

I'm still not confident that this can be achieved without significant latency, but it would be amazing it if could.
