Sony MiniDisc DV Cam Does Java, Ethernet 61
Lifewolf writes: "Sony's new DCM-M1 digital video
camcorder stores up to 20 minutes of MPEG2 video, 4,500
still images, or 260 minutes of ATRAC encoded audio onto a
MiniDisc. Even more interesting, the camcorder features a
Java 2.0 GUI and an Ethernet port so you can download your
files from the built-in web server." Now all you need is a hot chick or two, a lot of bandwidth, and a macro virus and you're in business!
Versatile cameras. (Score:2)
The one problem, well, not really a problem, just something that I'm disatisfied with is the lack of being able to upgrade features. I mean, all the features it has are integrated very well, it just doesn't have much expandibility, for a world which develops so quickly technologically.
I also have TiVo, which is a very nice device. The part of TiVo that's really appealing is the fact that every time they decide to integrate a new feature, they can do so by updating the software. This is made possible since it's running linux. It is also open-sourced, so hypothetically, you could add you own features to it! This, is the type of expandibility I'm speaking of.
I wonder if cameras will choose to integrate anything like this. I mean, not being able to check for software updates every time they check their schedules, but something parallel to this level of versatility. Having a java webserver is one step in the right direction.
Anybody have any idea what I'm saying?

I just came back from japan, where MD has almost taken over from CD as the audio format of choice, and I wish that the rest of the world went the same.
The biggest problem with CD's is that they're not robust - they've gotta be kept in the case, no fingerprints, scratches etc. - I want to be able to throw a CD on the pile when I'm finished listening to it.

Like I said above, I haven't noticed any quality loses with recording MP3s. Do they sound as good as if I had recorded from a CD? No, but this is the MP3 compressions fault, not ATRACs. Do not toss MD out the window just because it's compressed.
You can't blame either codec for the (relatively) poor quality of twice-compressed audio. They (MP3 and ATRAC) use different psychoacoustic models -- you know this -- which inherently will introduce more artifacts to the signal. If, hypothetically, MP3 were to be worse at pre-echo control and the ATRAC-flavor-du-jour were worse at reproducing high-end frequencies, it seems obvious that the two problems would both be evident in a file compressed with both codecs.
Even compressing MP3 to MP3 will produce poor results. The poster to whom you were replying has a valid concern with this practice, especially since Sony seems to be wanting people to do exactly this, with their line of Memory Stick ATRAC recorders that come with PC-based MP3 decoders. I personally would also be interested in an MD player that played MP3 files natively from cheap MDs.

It's kind of ironic that my MDs, which are supposed to be inferior quality to CD because they're compressed, sound tons better than the actual CD. I guess it's because Sony and Sharp aren't putting out crap MD players/recorders.
WHen pushing it as an audio format it has to go uphill against CD and it only offers size and durability as advantages (CDs are pretty durable) and it costs more.
MD has pretty much taken over Japan. Almost everyone has at least one and it has eclipsed CD sales. I would like to see the same thing happen in the US, but Sony seems oblivious to the oppurtunity that it has. You pass up size like it doesn't matter. I can tell you that sticking a portable MD, earbuds, and 3 MDs (222 minutes of music) is very, very convenient. Try doing the same with CDs. Durability is also important, and CDs are not durable. Try this: throw your CD around the room 10 times, use it for a hockey puck in your driveway, and scratch the bottom with a knife for good measure. Is your CD usable? If you did the same with an MD, would it be? Last, MD is not expensive. Sure, portable/components cost more than most portable CD players (for now), but the discs themselves sell for less than $2. The players are also 10x better in quality than any CD player I've ever owned.

The possibilities, as these utilities improve and drop in price, are magnificent. A kid in school could suddenly have more than just a 'voice' on a website. A protestor could share with the world, first-hand, what is occuring between him and the police (such as during the WTO incident). If you're stopped by an office, you can just flip the switch on this baby and have instant proof if anything unprofessional occurs. You could share your daughter's soccer game with her father who is across the country -- in real time.
But one of the greatest things I can envision about this would be for urgent situations such as natural disasters and military operations. Imagine cheap, unlimited access to what is basically a high-fi webcam to tell your wife goodnight, while you're getting under the covers, instead of from some busy commons or mess-hall that you have to share with a million other people.
Most importantly, imagine Mardi Gras . . . No more waiting for the photos of naked breasts to appear randomly on the internet. Suddenly, they're streaming from Joe Schmoe's MiniDisc recorder right to his website... Like I said, the possibilities are pretty endless.
The problem right now, of course, is that $2500 is a lot to spend. Even $1000 would seem pricey. And the camera itself doesn't look very comfortable. Perhaps if there were a way to easily transition it from a standard handy-cam setup to a more typical flat-standing camera that you could set on a surface somewhere and get in front of (like you would with a little Logitech webcam, strapped to the top of your computer, or elsewhere), it would be easier to handle.
It also says that images, once transferred to your computer, are in 640x480 resolution. That isn't horrible, but it doesn't say whether it can achieve higher resolution than that. In other words, do they mean that if you want to store 4500 images, it has to be done at 640x480? Or is 640x480 literally the highest resolution any single image can reach? For $2500, I'd want a finer quality.

I bought a Mini-DV camcorder last fall, and at the time it was "last years" model. They've been around for quite some time.
It has firewire and serial connections, as well as S-Video and RCA video and audio jacks. It can do still images, and the amount of images is limited to the size of the MiniDV cassette.
Fun fun fun! What sounds interesting here is the interfaces - ethernet with a built in web server. sounds pretty darn cool. Still, I'd prefer firewire, I think. But the web based interface lets idiots use the camcorder, too.
Anyone who is interested more in still images is better off with a real digital camera, though. Sometimes those 640x480 jpegs just don't do it. I routinely scale them down to 320x240, which then look excellent. But since I only use the images for the web anyway, it works out fine.

Not necessarily. MPEG-2 compression is almost certainly done in dedicated hardware. Otherwise, you would need the equivalent of a P-II 300 or so just to get it to work, which would make it large, heavy, even more expensive, and pretty hot.
I guess the httpd and Java are done in software, so presumably there's a 32-bit CPU in the somewhere - but how fast it is, I'm not too sure. But there probably isn't much in the way of storage - most of the stuff will be done on flash ROM, I'll bet. Maybe you could hack it to store stuff in the memory for the video, but possibly not (depending on how the hardware interfaces with it).
IIRC, there is an Java API specifically for embedded devices (basically just taking out the less common/useful stuff, I guess). Though I don't know anything about Java so take that with a grain of salt.

You don't need an MP3 player that uses MD! Portable MD players/recorders have the ability to record from any source, whether an analog headphone jack or an optical TOSLINK. Just get a $2 1/8 to 1/8 miniplug cable from Radioshack and record your MP3s to your MD. It takes a bit longer than just copying the files to a MP3 player, but the sound quality of MD is phenomally better than the portable MP3 players I've heard.
