One of them was me, i.e. no existing player will be able to handle it.
And I stick to what I said.
Diogen.
I would say it would be difficult but not impossible. I can think of a few ways they could do it. It would have to be out of band data. You would have the normal video stream for backwards compatibility then a separate data stream that old style players would ignore as a computer data file that would have the extra data in it.
If it were so impossible, why is there so much buzz about it now? I admit it would be an awkward fix to use out of band data, and would require some processing power on the player to handle putting the 2 data streams together. Perhaps it will be some half baked gimmicky scheme, but it will be interesting to see if it does indeed come out.
