The idea is to get the final framebuffer to extend into the VBI section of the signal where the teletext data usually is sent. Then it's just a matter of formating the pixels right.

Any idea, how they might be abused to achieve teletext or any other other effect?
It does not seems so but not evrything is controlled by registers, I know from libogc that there are a lot of stuff that can be controlled by sending I2C commands to the Video Chip but it's not very documented.Quote
Is there something that indicates Widescreen signaling support?

It'd be great for debug info. I know it's capable of placing the text anywhere on the screen, and (though I've only ever seen it when a crappy signal was messing up the text) displaying in multiple colours. So you'd have some nice debug output that can be toggled from the TV remote.Quote

Ah, now I understand. My bad, sorry. But what would you display in the generated teletext? Could you have a page for System Info, a page for memory observation, etc?

I am not completely sure that teletext requires that the data is written in blanking lines, just that's where everyone does it. Some, if not most, of the decoders shouldn't even care about what line the data is on, they just chose to use the blanking lines since they where not displayed.

Source? Almost all my TV-channel's have Teletext, and all new TV's in store have teletext support and I think they won't drop it for a long time.Quote

just to point out, most tvs wont support teletext in a few years anyway since teletext is being dropped by tv networks and tvs themselves
