[vorbis] Vorbis for PlayStation

[Mercier, Dave]

I'm not so sure the PlayStation 1 would have the power to handle Ogg. It's a
33 MHz MIPS 3000 in there. There is no floating point support. Integer math
isn't entirely speedy. It's basically about 100 times slower than a
contemporary CPU. There is a GTE coprocessor chip that can do faster math
stuff, but it's designed for geometry, and I'm not sure you could make Ogg
math work on it.

The PlayStation2 on the other hand would have plenty of power to handle Ogg.

Aside from the CPU, I think the bigger issue is how to deal with Ogg's on
CD's. First off, the CD with the player on it must be a licensed PS2
product, and the media has to be pressed and encrypted by Sony I believe
(unless your PlayStation is chipped). Then you have to switch in a regular
non encrypted CD - I'm not 100% sure this is possible unless it's been
chipped - although my gut feeling is maybe it is. As well, even if there was
a player, it's going to be a commercial product, and you will have to pay
$$$ for it. 

Really if this was something desirable and didn't involve much hassle, I
think you at least would have seen some MP3 players for PS1/2 quite some
time ago. I certainly would appreciate my PS2 being able to handle MP3's and
Ogg's but I'm not sure it's going to happen any time soon because of all the
roadblocks. Anyway, I'm not 100% sure about some of this stuff so don't let
me stand in your way from writing one.

Thanks,
Dave.

Hello.

Some friends of mine were playing with a PlayStation one day.
And after playing some Games they pushed a normal Audio CD into that
thing - and the music began to play. A crazy idea came into
my mind.

Just imagine: There are millions of PlayStations spread worldwide.
If it was possible to port Ogg to PS this could help to bring
Vorbis where we want it to be: Millions of families were
able to play Ogg-CDs in their living-rooms.

Does a PlayStation have enough computing power to decode Ogg Vorbis?
Is it possible to port a decoder to that platform? What
about license fees?

I know that porting the codec to PlayStation is not sufficient.
We also need a Player-Application that has to be on every
CD as we can´t upgrade the PS-firmware. So it is necessary
to write a tool that creates Ogg-PS-CDs, too.

Ideas?

bye,

Maik Merten
