Does anyone know how to perform a hard reset on the

T165? That is, a reset that wipes all stored information

(especially 1394 devices) and boots up in the factory

default.


Most DVD players accomplish this by powering up with

a particular button pressed. Couldn't find anything

in the manual.

I really don't know the specific answer to your question Ron, but I know if my JVC30K is not powered on, the menu will not show it as being available.

When I press the firewire button, it does not show unless power is on the device.

Does the unit really store the device info? I don't know.

Yes, the T165 remembers every DVHS device that's ever been

plugged in to it's 1394 port and assigns it a number "DVHS1,

DVHS2, etc". It's just like the JVC 30K, where it assigns

I-1, I-2, etc. On the JVC 30K, you can reset the 1394

numbers and start over at I-1. I'm just trying to figure

out how to do the same thing on the T165.


It's not a problem, just a curiousity. Since I can change

my development board ID at will, I could potentially end

up with hundreds of ID's stored in the T165.


BTW, all 1394 devices with 5C are required to have

non-volatile storage for the some of the 5C functions.

Once you have some non-volatile memory in your system,

you can use it for other things like remembering attached

devices. The nice part of remembering attached devices

is that the 1394 software doesn't have to send all the

Configuration query packets every time, which cuts down

on bus traffic after a bus reset (which can get pretty

heavy in a network with a lot of nodes all trying to figure

out each others configuration).

OK Ron, you've spilled the beans. What sort of "development board" are you working on and what application do you have in mind for connecting to the 165?

Very interesting. Sounds like you are testing your development board as a PVR or scaler type of device...?


Does the MCDI deinterlacing compare favorably with Sage/Faroudja's DCDI? Any idea when products integrating DoMiNo are expected to first appear?

I hear that the MCDI deinterlace looks very good. It's

a more advanced technique than DCDI, so in theory it

should perform better. Unfortunately, the price point

of Domino is a bit high for mainstream DVD players at

$30 in big volume. So right now it's being targeted at

devices that need an MPEG-2 encoder, like DVD-recordable.

Interesting stuff Ron.

Thanks for that!

Ron,


Can this chip be used for a device that takes in RGBHV and/or Component Y,Pb,Pr HDTV signals and encodes them to MPEG-2 for transport over firewire to a recorder such as the JVC 30K??? I always thought that would be a GREAT product to develop and sell for use by anyone that has a standard HDTV STB that only has RGB or YUV out, with no firewire. Then anyone with any HD-STB could record to the JVC 30K or Mitsu D-VHS.

A single Domino MPEG-2 encoder can only handle SDTV

resolutions and possibly [email protected] It takes 3 Domino

chips in tandem to do 1920h x 1080v HDTV.
