"Dual-screen" on a tablet PC ?

[dvtr]

Hi all; fist of all i'm french so sorry if I do misspelling or poor english.

Here is my issue :

I would like to build an application that displays some buttons on the tablet AND at the same time it displays a video on the external screen / TV .

Some constraints:
- Android 2.X or 3.X
- external screen / TV via HDMI

Do someone know a tablet in the market that can manage that issue? It's something like a "dual-screen" because it has to display AT THE SAME TIME both on the tablet AND the TV something DIFFERENT.

Thanks in advance for your help

Kind regards

The upcoming Sony Ericsson S2 has dual screen function, but its not yet released.

when you say "dual screen function" it means that we will be able to display something on the main screen (TABLET) and something else on the TV ?

Isn't there any other tablet yet on the market that can do that?

oh wait, I may be thinking different. Its also released apparently on AT&T.

However considering that the tablet is already dual screen, you would probably be able to show on TV one screen, while use the other for something else. Here's a link to what it looks like:

Thanks, but do you know if we can manage something with a tablet already in the market like the asus transformer ? I mean it has a output HDMI, where is the limitation to display something on the tablet and at the same time something else on the tv screen? is it a soft or hardware limitation? Is there really none tablet pc already in the market which a developper has already built an app that can do that?

Is there an easy way to use an external HDTV with your tablet?

we have chosen the Asus transformer's tablet.

Who knows where can we get some API supports (a website or wiki or something) for video (trough HDMI) application ?
