When many of us here were battleing out the complexities of manual controll or lack of, it seemed that there were some differances in how the cams reacted. Although this could be put down as user error in the experiments it could be a sign of different firmwares. Our cam would always revert to 1/30th shutter at 720p and 1/60th when in 480p.
I have searched the net the best I could, have found one site where the guy had turned of edge enhancement on his PAL PD1. If this could be done for an HD1 it would make this cam a real bargin.
Please keep us posted if anyone finds anything.

Yeah, I've seen the guy's edge enhancement bit change for the PD1. I've emailed him too to see if he has discovered anything new since then. According to the thread that he's on, JVC had something to say about his modifying the firmware and that's why that particular thread slowed down; but the babelfish translation leaves alot to be desired and I can only pick out bits and pieces from the original French text (I took two years of French in high school; alors, je ne comprende pas boucoup). I checked the HD10U's manual for any "legalities" of moding the camera and couldn't find any. I don't think hardware carries "licensing" restrictions like computer software has.

I basically have two goals with HD10U: 1.) enable concurrent manual override of aperture and shutter, 2.) to see if there is a 25p (or even the rumored 24p) recording mode. If it's easy enough, I'll look into image settings to see if I can reduce the contrast of the 10U to bring out details in black and minimize the brightness clipping... something more logarithmic rather than "cinematone".

Murad, I'll get back to you with how to tell what firmware is installed on the camera when I get access to one again sometime next week.

Dear Xander, Patrick,

How can I get a copy of the service manual? Is it available as a PDF file? I bought my HD-10 about a month ago and am interested in exploring what is
available thru service menus. The camcorder has already made a trip to
JVC for repair and I am not feeling good about it. It corrupted two tapes
thathad important recordings. There may be some information in the
service manual that I could use.

Thanks.

The service manual isn't going to tell you how to modify the camera unless you're an electrician. Then you'll have to use resistors or whatnots to mod the camera to change the signal. The service manual is really nothing but disassembly directions to get to the components; it also contains the entire bill-of-materials ("BOM") for the camera, so if a technician needs to order a part, he has all the part numbers.

THERE ARE NO SERVICE MENUS ON THE HD10U.

The JLIP connector that is used for servicing the camera is not the normal JLIP device that ships with consumer camcorders for video capture and control. The "service menus" are actually a separate piece of software that runs on a PC. The technician makes the mods on the pc and then uploads it to the camcorder via the JLIP port.

To find out which bits do what, I've been making changes using the menu options and then downloading the EEPROM data to compare with the original data I downloaded before I began. I haven't figured out how to write back to the EEPROM.

I haven't read through all this, but there is a way to program the PD/HD cameras through hidden serial port, and people are using it for frame-rate (PD1) and other camera settings. There is information on the camcorderinfo site, and I think I posted information on it (and links to the original French site) in the dvinfo alternative information imaging forums.

Anyway you could be of help by remembering and reposting the info or a least providing us with a link?

Links from "kandinsky" has a lot of info..

Yeah, I've seen the guy's edge enhancement bit change for the PD1. I've emailed him too to see if he has discovered anything new since then.
I apologise for not coming back earlier. Life took me away from PD1 for awhile! I am planning to do some more hacking asap.

I don't have any secret knowledge about PD1 apart from service manuals (schematic and exploded views.) I have made a JLIP cable and was playing around with EEPROM contents, trying to correlate to the known EEPROMs of other JVC cameras. That gave very scarce and useless information (mostly recording circuits settings, etc)

In the end I have started to alter every single byte of EEPROM to see what happens. I have run across few interesting areas: something looking like image softness, colour matrix values (how RGB colours are deduced from Green-Yellow-Cyan-White matrix) and colour correction.

As everybody else I was hoping to get 24p or 720p25 but I did not find anything that looks like that. It is not a single bit that needs changing but a host of parameters: timing, CCD offsets, number of pixels per line, recording density?

I was really hoping to compare EEPROMs of PD1, HD1 and HD10 but I only have PD1 at the moment...

HDV is moving in fast so probably the motivation to squeeze more out of PD1 will be disappearing really fast keeping in mind that as a camera, PD1 is pretty mediocre (dark sensitivity, colour gamut, energy consumption)... Unless, of course, there is still an interest.

What do you think and where do you suggest we go next with PD1?

I am still very interested since I just got my HD1 in June. I'm a bit scared to do a dump of the HD1 but if the cable is right for you to do it on the PD1, I think I should be able to do a dump for you to compare.

Is your JLIP cable the same as the one featured in this links picture?

http://pagina.vizzavi.pt/~ng93827a/JVC/

I'm hoping to reduce the edge enhancement on the HD1.

Is it possible for us to send you eeprom dumps for comparison?
I think the main intrest lies in in the fact that the HD series is still the only progressive HDV on the market, and if the edge enhancement of the HD1 could be corrected to match the HD10, it would make it a steal on the used maket.

Anyway you could be of help by remembering and reposting the info or a least providing us with a link?

Sorry, I was going on a trip when I posted, and I have just got back, and am going out again, and have much to do for a while. Use search on my threads in Alternative imaging forum here. and look though the JVC HD forums over at www.Camcorderinfo.com there have been people posting there. The link posted here is to the French site, but one of those people is at camcorderinfo, and another with the separate project adjusting PD1. I wish you luck, I am not interested in the old JVC's rather wait to see new JVC's (or HC1). Any news on the PD1/HD1/HD10 replacement (the model under the HD100)?

Re-edit:

Just looked at updated repair net link, and yes, Looks like both mentioned there, and Leo is one of the people I meant.

Thanks. I had already searched and found the threads.

OK, after few days of trawling the eeprom data I have finally found the parameter that controls the sharpening itself. Originally I was altering some colour values that seems to have been bringing the contrast down therefore reducing the amount of edge enhancement but it was still there around bright lights, contrasty edges, etc. The drawback was that it has thrown the colours off.

Now I have finally found the way to actually switch the sharpening off. In fact there are two independent sharpenings: vertical and horizontal. Each of them can be smoothly controlled from total off to total on, producing horrible oversharpened image. Default settings are at about 200 steps out of total 64K.

Have a look at the two B&W frame grabs at the bottom of the page:
http://www.lbodnar.dsl.pipex.com/video/

Softer image has sharpening completely turned off. I seem to like it more.

I can now move on to finding HD1 to play with. :)

If somebody can send me an eeprom image of HD1 or HD10 it would help the process a lot, however this would require a cable which is a pain to make (or buy.)

Do you, guys, think it is worth spending time on it or HD10/HD1/PD1 are gone out of active use?

Great work Leo. I personaly think this is a very worth while project. These cams are still the only HDV progressive cams on the market, and soon to be the only models under $6000 USD. The HD1 has become quite the bargin especially in the used market, Ebay ect.. and getting rid of the EE will make that cam a steal!
I will do my best to get the eeprom image.

Question on the cable needed for the HD1 to get to the eeprom, is it the same one as the one for JVC's DV cams?

I agree with Ken that the HD1 is a bargain once these edge enhancement and sharpening can be turned down or off.

Please continue the efforts, Leo.

Leo - it's good to have you on board!!! You are definitely going to be an asset on this hacking project.

I took a brief look at the new images you posted with the enhancement turned off. Now, I understand why JVC decided to leave it on. The image with no EE looks like "soft focus". The HD10U is a bitch to focus on the low-res viewfinder and LCD screen, so JVC must've done the EE to make focusing manually easier (I always knew focus was good when I saw the EE). But I do concur that it has a very film-esque look to it which I think is what this group is after. The black and white image reminds me of the softness of Canon's XL-1 and 1s.

Allen - to dump the EEPROM, the JLIP service cable posted on pagina.vizzavi.pt needs to be used. The regular JLIP cables don't work (or at least they didn't work for me). Use the JVC EEPROM Manager to download the ROM. I have been in contact with Paulo Ramos who wrote the JVCEM and am trying to get more info out of him.

I found out that JVC uses Tao Group's Elate RTOS to control their camcorders; page 70 of the HD10U's user manual states: "The Camcorder is a microcomputer-controlled device." It might be possible to program functionality into the camcorder since it's running an "operating system" on a microcontroller, not just a bunch of ASICs doing all the work. Anybody know how to get a copy of Elate without paying developer fees? And I don't mean "pirating" either... just a single user license for like $100 or something like that.

I'll be checking the thread every now-and-again, but I got a DP job coming up and have just been buried in preproduction crap and production is starting early August, so I probably won't be able to devote a whole lot to the thread and the ROM hack until late August or even September.

Keep the ball rolling!!! I think this thread might be organizing the talent needed to give us the HD camcorder we really wanted out of JVC.

Do you, guys, think it is worth spending time on it or HD10/HD1/PD1 are gone out of active use?
Yes, when cheaper competitors are released the secondhand price should be much less. I understand the newer HD1's might have improved performance in their sensors.

Personal request, any information on the possibility of 24fps conversion, or enabling gain (the reason it is stuck at 35lux) or the manual controls?

Thanks

Wayne.

..

I wish it were so, more likely it is a customised version of Elate for the camcorders that is not compatible with most others (you could still probably get around this on another Elate development package, but likely to be time consuming to do anything elaborate). The Amiga software player is based on Elate, I think that is available for $100 development kit (www.Amiga.com).

The camera might still have functionality locked in ASIC chips, and Elate might do little more than run applications beside them. Look at the data sheets for the central third party DSP that runs the camera, if it allows programming, a programmers manual for it would be a good place to start. You can probably find it's name from the HD1 announcements.

Thanks

Xander, I am glad we can pull the efforts together!

Softness: even taking CCD fuzziness out of equation you are still looking at the image produced by average quality lens on an area the size of few match-heads. I would compare the result to Super8. Anyway, it is much more convenient to increase the sharpness during postproduction if necessary. I am definitely happier with softer image. Again, some sensible degree of sharpening is OK but it will still show up as black contours around washed out areas like horizon or street lights. I will doublecheck if LCD image has the same softness as written on tape.

I am happy to reverse engineer the code if I could only extract it from the microcontroller (something I do for pleasure for years!) I feel they have two microcontrollers - main one with internal flash memory and mpeg chip with its software inside onboard flash chip. Again, so far we are only looking/playing around with the parameter memory, so to say .ini file for the camera, while its internal software is still completely unknown. There is a serial I2C protocol bus on the service connector (with a line called "Flash WR") but how do I use it?!

In theory I am not afraid to mess up EEPROM memory as I have its full copy and if needs be I can simply reprogram it back either in-circuit or having desoldered it off the board. If I mess up uC program flash memory, the camera will become a doorstop...

Anybody who has any ideas or hints, please speak up - let's move this forward!

I have tried to get JLIP protocol details from Paulo but he basically told me to go and find them myself. There are generic details of the protocol around but his software uses undocumented commands to switch into service mode. I also have service software for other JVC cameras (not for PD1/HD1) and it allows to read/write EEPROM too. I have logged serial protocol commands and it seems that Paulo and JVC software use slightly diffrent commands. JVC software also has some interesting features like monitoring live CCD sensor exposure matrix (6x6), focussing matrix and other useless stuff...

Personal request, any information on the possibility of 24fps conversion, or enabling gain (the reason it is stuck at 35lux) or the manual controls?I have a feeling that there is no single switch that would enable NTSC/PAL or 24 operation. There could be literally hundreds of memory locations to adjust with time/pixels/frequency parameters. I can comment on the possibility after I will have compared PD1 and HD1 or HD10 EEPROM memory dumps (I have PD1.)

Service manuals show the only difference between the three models are in controller chip index (like 12345-A or 12345-B) however this could be simply due to a fact that naturally chip revisions move forward (service manuals are from different dates.) Again, it could be simply a reference to a preprogrammed chip contents. If chips can be re-flashed, one can simply be turned into the other.

The camera might still have functionality locked in ASIC chips, and Elate might do little more than run applications beside them. Look at the data sheets for the central third party DSP that runs the camera, if it allows programming, a programmers manual for it would be a good place to start. You can probably find it's name from the HD1 announcements.For GR-PD1 camera:

main controller: NEC uPD70F3038F1A34 (flash version)
DV processor: JCY0172 (304pin BGA)
main bridge: JCY0173
DSP: YQ44920A
super encoder: NLC0459APB
lots of smaller ASICs (firewire, usb, DACs, ADCs, LCD controllers, etc)

NEC 703038 is a good start as it should be a generic controller and seems to be an overall managing controller but I can't find any info on it. When I was hacking Nikon F90X I got all the hardware and user manuals for their NEC chip directly from NEC.

correction: I did find NEC info but I think I did not find details of their FLASH programming (we actually want to read the flash memory.)

Just an FYI, what you guys are doing may void your warranty, and we at DV Info Net strongly suggest against doing that.

Thanks,

Heath

Lawyers and mothers. Ya just can't get away from them ;>)

Xander said it best. I will say one thing, someone tried to make his XL-1 24p, and after "slaughtering it," we didn't hear much. This is well before the XL-2.

heath

Yah, but we are JVC users. Much smarter. :>)

Question on the cable needed for the HD1 to get to the eeprom, is it the same one as the one for JVC's DV cams?It seems to be unique to HD1/HD10/PD1. The problem is in the connector itself. It is a very fine-pitched and hard to find part. I had to cannibalise one from a broken digital camera. Tried to get the cable from JVC but nobody sells them!

I have a feeling that there is no single switch that would enable NTSC/PAL or 24 operation. There could be literally hundreds of memory locations to adjust with time/pixels/frequency parameters. I can comment on the possibility after I will have compared PD1 and HD1 or HD10 EEPROM memory dumps (I have PD1.)

I think most of this stuff (except for gain) would require programming, pity that the component out was not live uncompressed, that would make the camera descent. For you guys in the US, 30fps is not so much of a problem for TV, so gain would be the more important one.

The PD1 should have uncompressed component out. The SD mode of the HD1/10 are.
My feeling is that the gain ability of the cam is quite limited. Upping the gain will probably incure massive video noise. The auto setting was probably tweaked to be as good as it gets.

HD component out would be good.

I understand there is particular problems with noise in the reds, and that the gain was lopped off to 0db (why the 35lux). But I would prefer (and with the newer sensor revision, if it exists) gain and some noise than a black image in some situations.

But I didn't buy a HD1 (I live in a 25p/50i market) has anybody heard of the HD1 replacement that is supposed to be due out soon, does it use the new 1/3rd inch Altasens? Wouldn't it be good if it turned out better than the Sony HC1. You know in the sensor industry there has been some good recent movements. Cirrus Semiconductor has bought both Fill factory and smalsensor, both use two versions of high latitude sampling, Fillfactory with high fill-factor and some other advancements. Altasens has the cheap 1/3inch mentioned, probably using their high efficiency low noise designs. Foveon is rumoured to becoming out with a cinema version for their x3 chip. So, they all have some thing to offer for interesting cameras (particularly if they include some of the features of their competitors).

A while back, I tried using the HD10U for greenscreen work and yeah, the whole image sensor seems riddled with red noise so the green screens looked a little grey and the macroblocking of MPEG-2 didn't help. However, thanks to Leo, he pointed out that the HD1/10 uses CMYW as the filter array on the CCD.

I did some research on that type of array and started looking at algorithms for color conversion (CMY -> RGB -> YUV). CMY has a better spectral response according to all the charts I've seen, but the fact there are multiple transforms to go through to end up with YUV might be causing some issues. I also wonder if it's true that the HD10U uses BT601 colorspace vs. the HD standard of BT709.

Sony makes their own CCDs and CMOSs. JVC has used AltaSens in the past, so chances are JVC will continue to use them since R&D efforts have already been established. As far as an HD1 replacement, I haven't heard anything; the only thing coming out of JVC that gets any mention is the 100U.

Perhaps JVC can't compete with Sony in the consumer market now that HDV is somewhat a toddler and out of infancy. JVC had HDV all wrapped up until the FX1 hit. They've always been kind of a bleeding edge/maverick of a company which is why so many people don't think too highly of them.

I'm a little wary of enabling gain on the HD10U for one reason: MPEG compression compresses better with no noise. If you crank up the gain, chances are the B-frames are gonna get screwed (misprediction due to the movement of noise). But it'll be nice to know at least we can control the gain once we find the bit. I think JVC left out gain control so it doesn't screw up their short-GOP compression (maybe gain breaks it).

I have more on my plate at the moment that I can cope with - e.g. I have found how to separate EE and sharpness. And I think I have found gain and knee control settings too. I need a controlled way to measure things that I am altering.

Colour conversion is a tricky beast. There is a good primer on WhGrCyYe matrix used in HD10 here: http://images.videosystems.com/files/127/305vssexpertise.pdf

You are right, Xander, there are so many stages in getting YUV that it is difficult to pick the optimal setting for all the stages. At the moment I have some great low light results but at the expense of colour saturation and separation.

Fundamental difference between 3 and 1 CCD cameras is that in 1CCD camera all four (or three) pixel colours are digitised by the same ADC and it is impossible to control ADC parameters (shift and gain) independently (i.e. on the fly). In 3 CCD camera you can pre-adjust the ADCs separately (gain is the first stage of ADC conversion process and is applied to analogue signal before the signal hits the ADC itself, even though it is done inside the ADC chip), therefore excess in one part of the spectrum , e.g. Red for flood lights will still allow Blue CCD chip ADC to use independent higher gain to pick up blue details.

What happens in 1CCD and especially with WGCY matrix, you have only one ADC and only one chance to set the gain to squeeze CCD output into ADC dynamic range. Naturally it is set to avoid overexposure. But because White pixels on WGCY matrix have nearly twice the sensitivity of Cyan, the ADC produces readings for Cyan pixels at only half of its dynamic range and it has later to be doubled in software. Thus noise is doubled too. Now if you consider that Cyan is opposite to Red and it is Cyan pixels that play major role in Red colours separation from the rest (Red = White - Cyan), this might explain bad handling and excessive noise in Reds in JVC cams.

Does it make any sense?

Perfectly Leo. Xander thanks as well. Gain like this is not a total loss, in guerrilla Documentary style, some sort of image in a dark place would be better than nothing.

Has anybody every broken one of these apart and applied a SLR lens through a condenser to get a brighter image, like some Canon Lens adaptors do for the XL1s?

"I have found how to separate EE and sharpness. And I think I have found gain and knee control settings too."
Wow, that is fantastic.

On a downside, untill someone can produce the needed cable for a decent cost, or provide a DIY for dummies, this experimentation may end at Leo. It has been said JVC does not sell the cable, so we need a solution for the masses (well the brave few.)

**Note**
I have reviewed the whole thread and realize it was stated that the plans at http://pagina.vizzavi.pt/~ng93827a/JVC/
are said to work with the HD JVC's. Good news. Does anyone want to add any tip'n'tricks to the info provided at this page?

Wayne - regarding removing the current lens and attaching a 35mm lens to the HD10, a friend of mine is working on such a thing right now. However, I think he's looking to attach a 2/3" lens since the multiplication factor will only be 2x instead of 7x (1/2" lens would be 1.3x, but I don't have one of those to give him).

Ken - the PD1/HD1/HD10's cable assembly from JVC costs $275. If there's enough people wanting to get one, I can perhaps place a quantity order and reduce the cost? I built the cable shown on the website noted above, but trust me, it's not worth the hassle (I'm a novice solderer and had issues). $275 is reasonable. :)

Xander, the chip in PD1/HD1/HD10 is ICX426AU which smells to me like a Sony part. They also have a gap in their lineup with that number so I assume it was a custom order.

So you have a cable!? I desparately need a dump of HD1/HD10 EEPROM to move any further. I was even considering buying one for the purpose of downloading it!

Xander,

We got two very similar threads going..

$275 is reasonable. My Paypal is ready to go.

I'm willing to provide the dump as fast as this transaction will go and that my GR HD1 wont blow.

Ok one more question..is the JLIP connected behind that little secret square door next to the iLink port?

Leo, I'd be still willing to donate towards your efforts on finding all the adjustments.

Allen

$275 is reasonable. My Paypal is ready to go.

Ok one more question..is the JLIP connected behind that little secret square door next to the iLink port?Here is a picture of my connector: http://www.lbodnar.dsl.pipex.com/video/plug.jpg
I found the plug that is the right pitch but slightly larger, so I had to file it a bit then epoxied it to breadboard and soldered three tiny wires. It also has a MAX232 level converter at the other end of the cable.

I can make a few commercial quality ones if I find the right connector that would be the right size. However my current thought is about an inch-sized self-contained unit with Microchip's PIC controller inside, couple of push-buttons and maybe a LED, that can be plugged in the camera in the field for quick settings changes.

Yes, "the thingy" is behind that little secret door!

Tell him to use a condenser instead, that way you should get no magnification factor with the right condenser, and some stops more in light (with right lens). That may get him to 9 Lux with a very fast lens, maybe a good SLR could get down to 5 lux etc. There is a Canon adaptor that does this so you can use their 35mm SLR lens on the Canon in this way. Search for my first post on DVinfo (on increasing camera image brightness) and go down towards the end of the thread there should be a link to another thread that talks about that adaptor. There might be an aperture limit to how far you can open up to, where the microlens array distorts the image because the angle of light is too great.


Thanks

Wayne.

To all who are interested:

I can get a group discount for the official JVC service cable if I can order 5 or more. THe cost goes from $275 to $250. Email me off list is you want to order one.

Personaly I would rather bundle my $ into a group project like Leo's. JVC has been a corporate bit#h as far as even acknowledging or giving any respect to us early adopters. HD100 $ is all they see now, after advertising the HD10 as the filmakers choice for the last two years. Besides the JVC cable will still leave us at square one, where as Leo is proposing something that can really make the cam versatile without supporting a corp that is dropping their pants in our direction.
I may sound bitter, but truth be told I have emailed JVC corp more than once asking about reported firmware upgrades or some such that gives newer cams of the same model # improved performance. I have brought up that even people who have had repairs done have reported increased performance upon return. Never a reply. Ever.
I will personally do what ever I can to evolve a cam that I think is grounbdbreaking and under rated. I only wish JVC felt the same.
I have a strong feeling JVC is planning to reintroduce this same cam as a new generation with the improvements we lack. HD11 for the masses?

Ken

The staff may only know what head office tells them. I emailed and called JVC about the Altasens product on their website, and they knew nothing.

I would suggest it be best to see the local professional distributor with a service centre about it, and paying them to do it, maybe as part of a service.

Wayne

Good idea. I have had local JVC work done befor, I'm just not sure of the " wink factor" if you get what I mean. I know very well how things are supposed to be done, but I think it is time for the consumer to be treated as at least somewhat important. JVC as a Corp have been complete jerk-#@%'s as to supporting a group of people who by buying their product's which gave them a vote of confidence in the most primative days of HDV. This should not be overlooked, but it has. We built HDV, and JVC does not give a damn. Mr. Freed? It looks more and more like our confidace in JVC has been out of loyalty rather than education. A simple backing of these not so cheap cams would put JVC back into the respectability zone, but that seems like wishfull thinking from a company who forgets you as soon as your purchase is made.
There has been repeated evidance of firmware and hardware updates of the same model #'s but no akknowledgements as to any advancements to the very same product lines, Why? Do we not believe JVC could not come up with a successor to the HD10? Really? They were just so stuck on how to improve it ?
Or is it an example of using the early adopters to absorb the costs of putting out a new cam and pretending it is new?
My only point? The HD10 is ground breaking, and the company behind it sucks like no other. What a conundrum.

PS - Sorry for the rant, but come'on. Wtf!

The introduction of the HD100 might work in our favour - they might not be as protective over the triplet cams.

Let's just get HD1/0 dump to Leo somehow.

Looks like Xander is the best person to provide the HD1 dump to Leo.
