JVC Announces Media-Centric Pocket PCs

An anonymous reader writes "infoSync World writes about two new high-end Pocket PC models from JVC, the MP-PV131 and MP-PV331. Running on Windows Mobile 2003, the Pocket PCs boast 128 MB SDRAM, built-in Wi-Fi and MPEG4 video and audio streaming and capture capabilities. The new devices are also equipped with software for use along with JVC camcorders. The new models will be available in the U.S. in September at $499.95 US and $599.95 US respectively"

It goes without saying

I would imagine that almost all future "high end" PDAs and Pocket PCs will be heavily media-centric - considering that most already are (the biggest selling points that marketers tend to focus on when advertising their newest hand-held is MP3 playback, image veiwing and manipulation, digital photography, and video capture and playback). Afterall, the PDA has long since evolved past a simple calculator and phone book. I always assumed that many average users upgrade to a Pocket PC for more power, power which is usually required to drive digital media (sure, you can play MP3s on a PDA, but high end media and their associated tools tend to require more power then a low end Sony Clie).

Too expensive

[Graspee_Leemoor]

Is it just me, or is the price of PDAs creeping up and up?

It doesn't affect me because I stopped using PDAs some time ago because of issues with battery life. I'd sooner trust my notes, addresses etc. to paper these days than an electronic device- and I'm a geek!

I smell a smash hit.

It works with JVC cameras and boasts WiFi, which means that small television stations can now act like the pros. Doing live broadcasts that require many angles--like sporting events--requires cameras with expensive antennas, etc. Now, these small stations simply add this $500 device and they're good to go.

Ah, advertising. Now it all makes sense.

"a typical camera goes at about 10MBytes a second, right?"

Wrong. 25 Mbit/sec is the rate at which consumer camcorders transfer video over Firewire. That's a little over 3 MBytes/sec. Pro DV formats (DVCPro, etc.) are 50 Mbit/s (6+ MBytes/s). 802.11b is 11 Mbit/s, which includes all the overhead and so your actal data throughput is considerably smaller.

Second, consumer cameras do NOT allow you to transcode on the fly, and so they CANNOT spit out video data at lower rates. When you run your MPEG-1 spots, those have been transcoded by a standalone PC (probably) to a lower bitrate, and a different encoding method.

You're now asking a PocketPC 2003 handheld to do real-time, on the fly video transcoding. It doesn't have the horsepower, and it's not stable enough for a production environment. Plus, you've got to have some way of switching between cameras for live events, which means DEcoding the data at the receiving end - figure on a PC per camera. If you're not going to switch live, then simply sticking a DV tape in each camera and doing everything in post is much simpler and more reliable.

Third, "more than acceptable" quality is fine if you're doing cable advertising. It looks like shit when you're doing live production. Looking "not bad, considering" doesn't get you return gigs.

So, to sum up:

Video bitrate is too high for WiFi.

PocketPC can't transcode in realtime.

Transmitted video over WiFi has to end up in a form that can be switched.

Simply putting tapes in the camcorders is MUCH simpler if you don't need to switch live anyway.

You might consider changing your .sig.

When will the CE line end?

[arth1]

The differences from old Windows CE aren't that much, except for added multimedia functions, wireless functions and CPU and memory speed.
The loser, now as with earlier new PDA OS versions, is battery life.

When will they do something about this? When they find out that MPEG4 is only useful if the battery actually last through a long movie?

i'd like to see...

A cheap machine ($200-$250)
NO video (adds expense)
MP3 player
802.11g
-- easy ad hoc connection mode with nearby friends
-- IM / IRC ad hoc over the 802.11
-- email via any open 802.11 WAPs
-- share tunes (like with Kazaa), ad hoc over the 802.11
-- simple PK crypto for "private" IM conversations
Java on board (so apps/games can readily be written)
small keyboard (like on palm titanium)

Is that hardware price point impossible for the features?

Yes, but...

You're almost comparing apples to oranges. That PDA that ran on 2 AA batteries for 4 weeks had:

• 4 shades of black
• 4 Mhz processor
• Had Address book, Notes, Calendar, To-do list, calculator.

Now, my Toshiba e740 with the extended battery has:

• Color screen capable of full-screen video
• 400 Mhz processor
• Address book, Notes, Calendar, To-do list, graphing calculator, universal remote, e-mail, full web browsing (with Javascript), and two expansion slots for hardware or up to 1 GB each of memory.
• I stream and control audio wirelessly from my computer to my e740 which I can then listen to whenever I'm connected to the internet.
• The battery lasts 11 hours of constant wifi usage

Now, these are two completely different beasts and the one concession that has to be made is battery life. Everything else is much better in the new handhelds.
