Tom: Definitely DirecTivo. It would be great if it were for one of the more affordable units like the Hughes GXCEB0T (same as the Phillips I believe) that can be had for $100 (new DirecTV customers) or $180 (existing DirecTV customers). More info here: http://www.orbitsat.com/cyberstore/p...sp?PID=GXCEB0T

Let us know, so we know which DirecTivo to get!
post #153 of 744
As far as modifying a DirecTiVo, all the current models use the same main board, so there soundn't be any differences in the SDI modification.

Thanks Bertrand.

There are quite a few players available for the mod. We will be sticking with the Panasonic, or rather chroma bug free, players for now. We will not be offering the kit to the end user for upgrade but will be doing the mods ourselves.

Denon 3300 is based on Panasonic A7. So it is chroma bug free.

We only sell modified players. And if we modify customers players, the warranty is lost.

Hi Tom,

I just noticed that my email reply to you with my Vigatec CCF attached had bounced. I wasn't ignoring your request http://www.avsforum.com/ubb/smile.gif
post #158 of 744
Could someone please clarify for me who will be selling modified SDI out DVD players in the US, and direct me to a place that I can find info and pricing in English and US dollars. Thanks for the help. The DaBooster Corp website is in French and pricing in Francs.

Tom:

I did not see the Panasonic RV80 listed. I thought it had the same chassis as the RV60? I have heard that the MPEG board is hard to reach though.

Let me know if you will service the RV80.

Rags
post #160 of 744
I doubt we'll do the RV80 - It is a pain to get to the MPEG PCB as it is under the transport. There will be many other players that are more viable. We will probably do just as Bertrand is - offer players and mods without warranties. We will announce pricing and start taking orders for the Denon 3000/Panasonic A7/Technics A10 soon.

I have one in front of me but can't figure out the pin outs with out a datasheet.
Take a look at the pin in on the ramdac. There is also some information on dxr3.sourceforge.net maybe. The datasheet for the ADV7175 (which I have on mine) is here; http://www.analog.com/techsupt/eb/li...5/adv7175.html

That page says; "The device accepts CCIR656 data and converts to Composite, Y/ C or RGB video signals in PAL or NTSC format."

I am very interested in this as well, but I would also like to try to make a shortcut and wire the CCIR656 signal directly into my bt878A, without goind the CCIR656 -> CCIR601 (SDI) -> CCIR656 route. It might be that it is difficult to do this without some form of buffering.
post #162 of 744
buffers are cheap and cheerful these days. You only have to get the loading right...ONCE. Then you are done.

So, this is actually the first time I stop in on this thread. I haven't read it yet. I was trying to leave at least one stone unturned, as I hate having done or understanding everything. But now it seems I have been pushed into a corner on this one. So, finally, I look at this thread. OK. Where do I get a SDI to 656 converter chip? standard 8 bit (parallel out) serial converter chip? they are pretty cheap. What is available with the proper handling?

I've just read half the thread, and it seems as if things are fully centered around the idea of converting to SDI, when the conextant chip on the TV/tuner cards will handle 8 bit parallel streams. Why not just leave it in the parallel mode and transmit that, and avoid all this hassle? The Zoltrix tuner card is already set up for such. I believe two wire would have to be put in place, or the clocking info is not fully ported. I haven't taken a full look at the requirements though. Basically, in this specific case, screw the SDI and leave it parallel. make sense to me. any opinions on the viability of that?
post #163 of 744
Ken,

This is an easy one, no offence intended! :)

All the interest in serial communications lately an a wide number of fields - computers, TV, anywhere high data rates are required - is because parallel signals skew during transmission. The various signals in a parallel transmission all arrive at slightly different times. For example, that ATA100 cables are limited to less than 1 meter length, even with alternate ground lines in the (ribbon) cable to improve things.

If you wanted to run parallel 8-bit raw video at HDTV rates (1.5Gbps? - not sure) you'd be limited to cable lengths of no more than 1m, I think. Someone who actually has the relevant qualifications can fill in the blanks. But if you want to run 10 feet or more, serial is the only way to go.

(Of course, I may know just enough to be dangerous... I'll defer to experts in the field. :D)

post #164 of 744
Another straightforward question. I seem to remember different formats being thrown about. One of them seeming quite like that of the DVD encode format, as far as it's digital transfer. Is it possible, to transfer the DVD parallel stream right to the TV capture card (up to 24 bit word length), in a parallel buffered pull from the DVD's IDE cable? the internal distances are close enough. And, if a capture card can be modified easily enough, it might prove interesting to use Dscaler program algorithms on improperly flagged DVD's. this seems to be the primary use for dscaler. And, if possible, but mostly a wiring job, I'm game. tiny wires don't scare me. I'm the kind of guy who fixes motherboards and swaps surface mount IC's (200 pin count VLSI IC's have been done). No big deal.

If I have to make a tiny board, with the buffer (for the bus pull) IC,and then the ribbon cable that attaches to the conexant 878A (the chip supports a 24 bit data path, at up to 20 mbit , if I recall correctly) pins on the capture card, that's no big deal. Suddenly, we have a package of algorithms for DVD use that where previously unavailable to the HTPC user, and a whole baseline for creating our own scaler functions on the HTPC platform.

I'm game if someone wants to help out. The big problem I see, is the fight for the bus, or how to enable the DVD drive in the HTPC, without enacting a DVD software function. Basically, get the DVD drive running and controlled, but, no bus use by the DVD as far as data transfer goes. Oh well, more nonexistent software.
post #165 of 744
Also, transfer rates and speeds are at SD levels in this case, not HD, so the data is rather limited in bandwidth.

I just realized I am talking about the creation of the one box HTPC based DVD solution, with remote control, and hgih horespower CPU's in use on the mobo, and the VGA card..where the lates generation that is to be realeased is SUPPOSED to have component video function.More than half of the software is in place already. most of the capture cards come with a remote control interface.

Hmmm.......
post #166 of 744
Ken,

What you're proposing sounds feasible to my limited experience in cable transmission, but I think you're missing one or two steps.

Data on the DVD is (usually) stored in encrypted form (our friend CSS), and in any event the audio and video streams are multiplexed in the file. The file contents - the data you would pull from the drive unless I'm missing something fundamental - would need to be decrypted and the VOB transport stream demultiplexed into MPEG-2 (video) and AC-3/DTS (audio) streams before the MPEG-2 data is then decoded into raw video.

Once you have the raw video, of course, you can feed it into the 878 chip, right? But it seems to me that we're talking about a full-on MPEG decoder card being required between the DVD drive and the video input card.

That's not to say that it wouldn't be just 2 or 4 chips on a tiny daughterboard, but it's more than just a buffer.

Perhaps a better approach would be to simply return to your original idea of parallel data transmission between a DVD player and the PC - you'd still need a buffer for this to force alignment of the incoming parallel data to a clock edge - and restrict the cable length spec.

Gee, this is starting to sound awfully Rock-ish, and perhaps further discussion would be better in a new thread as it no longer has much if anything to do with SDI.

- David Eddy
post #167 of 744
Yeah. I thought that from the first that only the parallel run of the signal might be feasible. Short cable run...and some signal alignment. Ie., clocked buffering. the trick is..what chip? Start looking, I guess.
I can do this sort of thing, but, I prefer hardcore physics by a wide margin. you know, making something out of nothing, literally. All this stuff has been done before, so....I have a hard time keeping interest.
post #168 of 744
just pushing it to the top, so that when i have to read it to research, I don't have to do it through a search. A bit more convienient.

Question:

it appears as if the Panasonic RP-56 DVD player I bought has the SAGE FL2200 chip in it....interesting. Anyone know where the tech manual on this chip can be obtained? Is it available at all?
post #169 of 744
Hi Ken,

You might check with Mark Fontana: I believe he at one time researched the possibility of adding external inputs to the Fli2200 and then capturing its output in a digital form.

Cheers,

I plan to offer them to members as kits once everything checks out OK. I will post again when the first article is tested.
Hi Robert,

Did you make any progress with the PCB? I have looked for the National eval board but they still seem to be out of stock, do you know of a source?

I will make a PCB myself if all else fails, but if you are prepared to sell me a couple then that would be a much better solution for me!

Are Immersive only offering an upgrade service, or is it possible to buy their board? I am in the UK and don't particularly want to ship a player to the states, and I can do it myself anyway...

Cheers,

post #173 of 744
Thanks for bumping this thread, will the National SDI daughter board also work for adding a SDI input ? It was mentioned in another thread that the iScan Pro chip has the 656 SDI input capability if a pin is shorted.

Now this would really be poor mans SDI, as a Dune with SDI at over $7000 is anything but.
post #174 of 744
Ok, I found some information on my STB made by Thomson, here is the information sheet on the STi5512 chipset

http://us.st.com/stonline/prodpres/d...e/dtv/5512.htm

Im not sure whether SDI will be possible for this;

Digital YCrCb output in 4:2:2 format

Outputs RGB with 10-bit DACs and CVBS, Y, C and component output (YUV) with 10-bit DACS

IEEE1284 port, or IEEE1394 A/V link layer interface

(Doesn't seem to have the DACS onboard itself, does this mean you can get a digital output at this stage ?)

Any feedback appreciated.

Edited;

National Semi also have an SDI Input decoder board, this could be put into a scaler yeh ?

Hi there!

Has anyone tried to apply a CLC020 to a DVB-S or DVB-T STB? Or even checked if it's possible?

Kalle
post #176 of 744
Hy Kalle, I have Nokia STB mod with SDI -- IMO it´s D-Box 9500 with Phillips chip SA... something.Other Boxes I don´t know to mod... .Of course you can ask Puschi from www:marwin.com here in Europe to fix that for you. Regards Jürgen
post #177 of 744
Thanks Jürgen! That's great to hear. I think I'll check if I can do it myself.

I've been digging around in the SDI arena today - a few facts, a couple of questions...

Gennum makes some SDI chips, and better still, some evaluation boards. EB9022A carries the GS9022 serialiser (parallel to SDI); EB7005 carries the GS7005 SDI receiver (outputs SMPTE125M), and so on... The GS7032 serialiser also contains an NRZ to NRZI convertor, and a bypassable SMPTE scrambler... would that help in a DVD SDI application?

Now, the question: is a good 'ole Sony 7000 SDI-modifiable? The fact that I have one knocking around is instrumenntal in my asking...

Neil
post #179 of 744
Finally this thread came back to life....... Jurgen, please talk to me about Euro SDTV box'es which are SDI'able. You have me falling over here.

BTW : Check out my website with the SDI section. I have all the info on the various Gennum and NS prototype SDI boards.

Yes, the Gennum chip sets are widely used for SDI applications. You want to keep the NRZI and scrambling in place for standard SDI. They make these bypassable for non-video applications.

The National / Comm Linear chips are gaining popularity because of cost and availability.

Then there are the classic Sony and Thomson 1600 series chip sets. These are still very expensive and have margional perfrmance compared to the new Gennum and National offereings . They have a captive customer base though because they were widely used until Gennum got into the game in the mid 1990s and they fail often.

Don't know about the Sony 7000. For any device to be modified it must...

1) Have 27mhz clocked raw video data in 422 format with EAV / SAV added.

2) If it's not multiplexed and seperate y cBcR, you need to build a mux.

3) If EAV / SAV is absent you need to build logic to add that as well.

4) Be careful of loading the video data buss. I buffered mine right at the tack in points with a small sub board. Otherwise the players internal encoder was being killed by wiring reflections. (I wanted to keep the players normal outputs functional with SDI in use)

5) Fortunatly if you are Altera or Xilinx savy and have the tools, these are fairly easy logic circuits and most current FPGA's have the needed speed.
