Hi Joe

First what an exciting product.  I am a day one (pre bought on amazon) osd1 user and I just got my evaluation system up and running. Could you perhaps share a little on your roadmap and next milestone objectives?

2nd, am I understanding correctly that the IO will only use IDE drives?

3rd Gigabit ethernet is cheap now. Why are you limiting it to 100mbs. Seems to me that the very nature of hd storage is a fat pipe no matter what.

Kind Regards

Can I ask if you are talking about the OSD2 - developer board, or the Neuros Link, the current consumer product?

I'm sure Joe can furnish you with more details than I ever could, but I can relay info I've gleaned from various sources.

First off, the OSD2 board is hardware complete, but does not yet have a nice consumer plastic-y case, instead coming in a mini iTX development case. Why the delay?

The codecs are being developed by Texas Instruments, maker of the DM6446 Davinci chip which powers the OSD2. High definition codecs push the CPU to the max, and require skillful use of the resources available, so are tricky to develop, and thus takes time. So Neuros are waiting for TI to finish this job, so that with the core playback & recording features up, then they can build a GUI & sell sell sell!

I can't supply an ETA for this, but I'd hope by Q3 something may appear.

I believe the board supports SATA hard drives, see
http://wiki.neurostechnology.com/index.php/OSD2.0_HD_Specifications
GigaBit ethernet is a bit unnecessary IMO, not many consumer grade routers support it, and I see no massive benefit to the OSD2's feature-set.

Hope this answers some of your questions. Note I'm not a Neuros employee, so E&OE Smiley

Ridiculous!. I have been running Gigabit Ethernet for eight years+ (mid-2000), back when a 5-port GigE switch was $250.
Now the cost has gone down to $40-$45 in the small "desktop switch" variety(for placing under a desk/workspace)

See:
Netgear 5-port Gigabit desktop switch - $45
http://www.amazon.com/gp/product/B0000BVYT3?ie=UTF8&tag=showitem06-20&linkCode=as2&camp=1789&creative=9325&creativeASIN=B0000BVYT3

300 Mbps Gigabit Ethernet->Wifi-N wireless router $89
http://www.amazon.com/gp/product/B000VIT0G6?ie=UTF8&tag=showitem06-20&linkCode=as2&camp=1789&creative=9325&creativeASIN=B000VIT0G6

LaCie 500Gb Gigabit Ethernet/USB external HD: $153
http://www.amazon.com/gp/product/B000YHGLDY?ie=UTF8&tag=showitem06-20&linkCode=as2&camp=1789&creative=9325&creativeASIN=B000YHGLDY

So Gigabit Ethernet makes a LOT of sense for home networks, specially now that WiFi is faster than Fast Ethernet and that cheap as chips external hard drives are coming with GigE.

A GigE is less than $15 per chip (or was three years ago)
http://www.commsdesign.com/new_products/showArticle.jhtml?articleID=194200022

Sticking to 100Mbit fast Ethernet only makes your device look old and underpowered.

If the device is able to operate at USB 2.0 speeds (for instance, when you plug an external USB 2.0 hard drive) why create an artificial bottleneck on the network port?

Well let me defend my point of view more concisely. I really should have typed:

Quote
GigaBit ethernet is a bit unnecessary IMO, and not many consumer grade routers support it

The initial part of the sentence I believe is more relevant. If the OSD2 is designed to play & record content up to 1080i, then the ports on the board should be fast enough to stream the file. So doing some rough math:

1920x1080x29.97fps x Qf estimate[1] of about 0.27 = 16.8Mbps

for video data alone. Adding in sound and container data, the stream rate should be well within the actual capability of 100Mbps ethernet. So Gigabit is unnecessary for the OSD2's core functionality.

Staying on the core functionality notion, while it will be nice to plug in your external USB hard drive into the OSD2 and have it shared on your network, that's not what it is for. It's not optimized for transferring files from USB2 to ethernet, and the 300Mhz CPU may be the bigger bottleneck.

One thing I think the OSD2 does need is 802.11n support, because that will future-proof it much more so. (I consider it akin to the USB1.1 port on the OSD1 - its greatest hardware weakness)

But you are right in that Gigabit ethernet is the way forward, especially considering High Definition video files that we'll need to deal with. However such products are still more expensive than the 100Mbps routers in my local PC store, and consumers mostly prefer faster wireless IMO.
-G

[1] This is based on rough estimate from OSD1's MP4 algorithm, where 1 hour of 640x480 content at 2000kbps = 1GB, implying a Qf of roughly 0.27. I imagine the OSD2 will have a better compression algorithm so this value will be lower, but this is worst case.

Thank you for your update on OSD2... TI delays causing the development to "stall" until is it resolved we will see Command Line Interface only and expect Nothing more than this until TI resolves the issues.

Anxiously waiting...
