We're heading for the stars. Obviously we still have to manufacture it, but let's be honest, after looking at those schematics does anyone doubt that we'll get there soon? BTW, that @ is me looking out a porthole, wearing a spacesuit.
About time, but nothing special

This isn't that amasing. Firstly this is done using a CPU and a DSP. No ogg specific hardware is mentioned. Secondly the chip isnt even a chip but a FPGA implementation. They can show that it works but mapping it out is another chalange if you want to keep it very power. Basicly what they have done was to pick up a core and stick it on an FPGA then compiled ogg/vobis for that CPU's ISA. Place a bit of a bootloader and something to handle the I/O and its done. No magic.
One more point for the open source community

Hopefully this will be just one more step towards commercially available, open source-based devices. I can't wait to get my hands on one of these devices, personally.
I wonder if any of the big vendors will pick them up?
What rock have you been living under: Ogg Vorbis is a new audio compression format. It is roughly comparable to other formats used to store and play digital music, such as MP3, VQF, AAC, and other digital audio formats. It is different from these other formats because it is completely free, open, and unpatented.
Ogg Ogg is the name of Xiph.org's container format for audio, video, and metadata. Vorbis Vorbis is the name of a specific audio compression scheme that's designed to be contained in Ogg. Note that other formats are capable of being embedded in Ogg such as FLAC and Speex.

It works the same way all OSS does. Someone wants it and thinks it should be free. So they write it on their own free time and put it on the net. Somebody else goes "oh, good idea, let's make it do this too," and adds to it. Repeat until you have an audio format powerful enough that a company feels it's worth implementing in a chip.
Now, the company doesn't have to pay anyone, so it's much cheaper than developing MP3 chips. They're gonna make money by fabricating them and selling them to other companies which want Vorbis decoding (It's not ogg vorbis: ogg is the container format.) Or, at least, that's what the fab/design company is gambling on.
Then, the player manufacturer, who bought these chips, puts them in players and sells them to a public for some enormous amount of cash. I say enormous because MP3 CD players are $40 in Target now, and frankly a 10 gig hard drive isn't that many CDs (especially now that CaseLogic sells CD cases whose sides are speakers.) Okay, the 60 gig models still have some appeal, but when we get portable DVD MP3 players, it's *over.*
I mean, shit, then I'll be able to keep my whole audio collection on six discs. (RIAA notice: I still have all the CDs they came from, with the exception of a few which have suffered pets, so back off in preemption, you self appointed gestappo. Do something useful and constructive with your dollar, instead of making yourself the butt of "look what DirecTV/SCO is becoming" jokes. Assholes. Maybe find a musician that isn't paint by number.)
In the meantime, the parent was modded insightful? Interesting I could see (I don't think it is, but there's a sensible stance for it.) But what insight did s/he provide? Do you people pay attention when you moderate?
I'm gonna go back in my cave and grumble at the walls for a while. f'ing rock.

Seems to me the chip is not a reality.
A design for it is.
Which is merely one step past "idea".
By now I know i dont have first post, but shout outs to whoever does.
I don't need no instructions to know how to rock!!!!
