Not shure how the Sony PS3 and PSP connectivity works, but the remote play option wich allows for the PSP to display the PS3 games cannot be generated on the PSP.
The PSP has not the power to generate the PS3 gfx, even in low resolution, so the remote play option has to be some kind of streamming. I believe the PS3 renders the screen into the PSP resolution and streams in a flash movie or some other way. The PSP is only used as a screen and the buttons as input.

Although the N800 lacks the psp bottons and analogs, it would be nice if we could do remote play in it.

So?? Is this possible? Anyone willing to take a shot at this?

Interesting idea. The PSP remote play system apparently uses AVC and AAC streamed over a network. No idea how you'd go about it, though!

Well... Apparently video can also be streamed, and not just games.

It would be awesome to have an app that could do the same on the n800.

Music, video (but not DVDs or Bluray) can be streamed. Certain PS3 and PSN games can be streamed. All PS1 games, both downloaded and disc-based, can be played through Remote Play. Web browser and Playstation store is also supported.

But honestly, there's little point to bothering with all this when you realize the tablets can't really do much with all this and also just don't have the power to keep up.

The PSP is cheap enough these days anyways.

Well, cheap is not what matters.

A very small CRT TV is also cheap, and also a FM radio is cheap. A Mp3 player is also very cheap.

N800 does all of this, and software was made for it, so CHEAP is not an excuse.

Now, about the power to keep up. Since we are talking about a transcoded stream, and the N800 can do this very well (I use Tversity on my PC to stream to my n800 using Canola), we cannot talk about lack of power.

All that is required is some knowledge on the formats streammed so that the N800 can receive the image and audio (and they are not uncommon) and send inputs that can be acknowledged by the PS3 as the PSP buttons.

They're not uncommon? How do you know? It sounds as though you've already done some research; if you could post any links to your sources, it might help more people care. (I don't have any PS[123P], so while I've a passing interest, and might post helpful, useless, and/or annoying comments, I'm not gonna go dig this up. But I'd probably at least skim any resources you link.)

I haven't researched a thing... I cannot tell that for shure. All i know is what is in wikipedia. I hope this thread helps on figuring that out.

Wikipedia says: "Remote Play works by encoding a video and audio stream (most likely AVC and AAC)"

It's an intriguing idea, but I expect you'll need to wait until the PlayStation hacking scene manages to decode the protocol on PCs (assuming it's possible - it could be encrypted). Only once that is done can thoughts be made as to porting it to the ITs.

as of next week, firmware 2.20 for the ps3 will allow the psp to remote control the ps3 for music. Not sure about videos yet. I love to have a psp for that alone.
