I seem to remember people saying that Zurg's red eyes in the opening scene of Toy Story 2, where Buzz is fighting Zurg was a definite indicator of the chroma bug.

This is the best discription I've seen of it:

For all the concern about it, it seems like a pretty minor issue.

That's exactly what I was looking for!!! I take it most processors fix the problem... Rock, HD Leeza, DScaler... so it's a moot point now...right?

The Chroma filter of DScaler can fix the chroma bug problem.

Nacho,

It all depends on the datastream present. A picture of the interior can be helpful, but when there is a video encoder present, you cannot see on the picture what datastream it's using because these modern video encoders support multiple datastream modes. Only probing with a scope can determine if modding is possible.

regards,

Roberto

I have read somewhere that is "like" the Humax 5100 and the 5100 is SDI modifiable.

The doubt now if is the DVD and the Sat receiver use the same encoder, Don´t you?

sorry but have to ask....

which dvd players are eligible for the SDI mod and which ones aren't. In my case, the SDI mod for a Panny XP50 is what i need. The mod should work but i have to ask.

In your web page

http://www.pmsvideo.com/index_topic....ath=/1636/2523

you talk about the National Semiconductor SDV020EVK SDI Board but is still in Preliminary Status at the National web page.

Anybody knows when it will be abailable?

Nacho.

P.D.: Only $100:)

Nachin,

The sd020evk is based on the clc020 chip. This is an old version of the clc021. I don't think this board is available anymore.

Roberto

Thank you Roberto.

The new ones
SD021-3EVK
SD021-5EVK
are also non available or preliminary status,
There is a realease date for them? and more important ...

Which are the correct for each player?

I have also see the SD901EVK receiver,

Could we in a future modify our DVD recorders to record the SDI signal from our mod SDI satellite receivers?

And about the HDTV
SD130EVK
SD131EVK
Dou you think are they compatible with DVD players?

Nacho.

I haven't seen one using the new development boards. However there are a number of forummembers who are selling comparable sdi transmitter boards. for example the board of atman is very reasonable priced and is shipping worldwide. Also forummember Tester007 is going to sell sdi transmitter boards, however i don't know his pricing.
btw these boards can only be used when the player has a bt656 datastream available. All other players can be categorized into 2 groups;

1) no datastream exposed, for example the latest versions of cheap dvd players using a single chip solution where the analog video is coming directly from the chip. There is no way you can add a sdi output.
2) no bt656 datastream. If you are lucky it's a bt601 stream with vsync and hsync. Other possibilities are unmultiplexed videostreams with whatever sync signals present.

This tread got reactivated again by Mavromatis by his quest to get a SDI mod for his Pioneer DV07. It has resulted in a mod which accepts a bt601 stream with hsync and vsync. However we noticed these kind of videostreams and sync signals are not well defined by standards. You have to modifiy the code of the fpga for every different player.

The SD901EVK receiver could be used to mod a dvd recorder with a sdi input but it all depends on the recorder ;)

the national hd-sdi chipset could be used to modify a dvd-player, but why use it when sd-sdi chipsets are still available.

I have found one place to buy the SD021-5EVK card with 5 volts operation.

Anybody knows if is indicated for the Panasonic RA82 or other DVD player?

Just to give you all an update... Roberto, Dan and myself successfully converted a bt.601 stream to bt.656... so my Pioneer DV-F07 300+1 DVD now outputs perfect SDI. YEA!!

The intent was to make this solution available to everyone, but we have noticed (like Roberto stated in a previous thread) that timing is different across devices. So we are working on a device that will solve this and possibly make it a drop in unit for all devices. We now understand how this all works and think there is a way make it universal. The outcome should be an easy and inexpensive solution to get SDI out from any device that has an accessible bt.601 stream. Everyone should be able to watch the best possible picture at a reasonable price. We will call it... "THE ULTIMATE SDI MOD".

I know there are a bunch of you interested in a converter board right now, but it would be a pain for you guys to setup your system to compile verilog and then tweak the code until you find the perfect timing values. Plus, this would also require a JTAG cable to program the FPGA... adding to the cost.

So bare with us as we figure an easy solution for everyone... wouldn't it be sweet if all DVD players had SDI out as a standard feature and we didn't need to hack them!

Hi;This might be slightly off the topic, but maybe someone who has posted in this thread can give some insight to the following;
I have a few questions;
About the comparison(s) between SDI(sd/hd) and DVI. They're both
digital formats, although DVI can communicate in both directions.
SDI seems like the easiest one to implement, so why did the
industry opt for DVI. Was it because of the 2 way com. of DVI.
There seems to be alot of interest in SDI mods for dvd players
and digital boxs. Why not just mod them for DVI, or is DVI presently
by license only? I haven't done alot of research into DVI chips,
but it appears that only TI and Silicon Images are the only two
companys making DVI chips. The SDI mods seems to be getting great
results, as they should be, by bypassing the analog stages it should
be a huge improvement. So why did the industry not use SDI for a
format, or is that a loaded question with a 100 different answers.

The trend now seems to be that DVI is appearing as o/p's and i/p's
on alot equipment. Obviously these are compatable to be just be
connected together, ie; a DVD player directly to a projector, so why
the necessity for a piece of equipment in between these two, like
a Leeza or the aSimilator, for scaling etc. Could this not be easily
done in the front end of the projector, the DVI interface has the ability to ask the DVD/digital box what it's output is and then it could adjust the scaling accordingly to match the format of the display. After all, the projector already does the functions like 3:2 pull down etc etc, so why not the scaling too.
If more inputs are required-DVI inputs only of course, a simple input switcher (hence inexpensive) could be inserted between the two for this purpose. The ability to do the scaling too, may add a little more to the end price of the projector, but in this age of LSI chips it shouldn't add that much more and it should be a whole lot less than having to buy another piece of gear like a Leeza or aSimilator. Of course this would hurt the bottom end of some of these companys that market such eqiupment now needed for scaling purposes.
I hope the industry is headed in this direction in the near furture.
It's not like the manufacturers of projection equipment don't have
the know-how when it comes to implementing these changes into the projector.
One other note, there seems to be alot of people stating that using component connections gives better results than using Dvi connections when it comes to the i/ps for a projector.
Any feedback would be great.
Thanks.

Walter

wts,

SDI is a well defined pro-video standard with no copy protection implementation. The movie industry would never accept this standard for consumer products. Only because HDCP, DVI is accepted as a high definition digital output. DVI is primarily designed to drive a display device.

Why are the SDi mod's popular. Well there are a number of video processors (including SDI-Silk/Dscaler and H3D I/II) available which accept SDI. To get the best connection between you player and the processor you want to stay in the digital domain and avoid any unnecessary digital-analog-digital conversions.

Until recently there where no processors with DVI inputs and players with DVI output.
The biggest problem are the players with DVI output because they have to process interlaced video into progressive video. The processing in the player is only a part of the player and therefor subject to compromise in regard how production costs of the player are distributed.
A video processors soul purpose is to process video therefor no compromise has to be made. (of course it all depends how much the product retail price is) The same apply to projectors.

However with the introduction of the new highly integrated "video processor on a chip" chips could tip the scale in favor of integrated video processing solutions.

just my 2 cents.

regards,

Roberto

Atman... the F727 is the 300 changer... just like the DV-F07 Elite and it has a BT.601 stream (with hsync and vsync lines). I have both modded and they work perfect (with the FPGA mod). I don' think it's the same as the 626...but it's easy to find out... pop the cover off and see what type of encoder it has :)

Hi Danny,
Philips SAA7201 is a MPEG decoder used in sat receiver.
http://www.semiconductors.philips.co.../SAA7201_3.pdf
It seems that it outputs BT601. Can it be SDI-modified with your FPGA?
