I'm hoping some of you D2V enthusiasts can shed some light on a problem I'm having with video on a used D2V I just acquired. The unit has the latest 3.09 firmware and was very clean, purchased from a highly reputable seller.

I'm seeing video artifacts (mainly horizontal lines but I've also seen what appears to be pixel noise) generated by the D2V most noticeably around the edges of graphical images and text overlayed on video.

The artifacts also manifest themselves in regular video around the edges of clothes and people especially when they are moving. Basically, the HDMI (1 or 2) output of the D2V looks terrible from any source.

When I connect my cable box (HDMI) direct to the TV using the same cable that was running from the D2V, no artifacts - the image is completely clean. So it's not cabling, not my TV, and not the sources. The problem tracks to the D2V.

The pic of my TV screen at this link shows the problem. If you download the original image and zoom in you can see the artifacts easily.

Notice the horizontal lines to the right of the red box, around and inside the 'p', to the left of the blue box, to the left of the 'e' in "Gopher" and to the right of the 'e' in "Defies", around the '#' sign, and embedded in the letters in the text of the scroll box in the bottom of the screen.

These artifacts are generated by the D2V from all HDMI sources I feed into the it - Apple TV, Oppo BDP-105 playing DVD or Blu Rays, cable box, etc.

I've tried changing all the parameters in the Video Configuration. They are set to auto now but I changed everything and nothing gets rid of these artifacts.

Is there something I need to do in the D2V configuration to fix this? I've tried everything I could find to change and what concerns me greatly is that HDMI sources direct to the TV - not passing through the D2V - look great. When I run them through the D2V they are loaded with artifacts.

Thanks in advance for any suggestions.

Chris

I suggest to start that you Reload Factory Defaults and then re-install the firmware. During the install process, disconnect all your HDMI devices (Sources and display) from wall power to insure you have no live HDMI connections. Afterwards, do *NOT* reload any Saved settings. Instead, make just the minimal Setup changes needed to get video output to your display. Do *NOT* make any changes in the Video Source Adjust menu. Just in Setup.

Now, go into Video Source Adjust (press and hold the "7" key) and scroll right to the Patterns tab and select a pattern such as Color Bars. This is internally generated, independent of any Source device. Do you still see the artifacts?

If so, exit Video Source Adjust (Back button) go into Setup and temporarily change your output resolution to 480p (not 480i). 480p is the "simplest" signal for HDMI to carry. Go back into Video Source Adjust and check again. If the artifacts are still there, call Anthem Tech Support and show them your picture. It is possible the video board connections may have shaken loose in shipment, but the type of artifact you are seeing is not one I've seen before.

If the problem is gone at 480p, then try 1080i and then back to 1080p. If the problem is gone at 1080i but present at 1080p that's pretty strong evidence of an HDMI bandwidth (i.e., cabling) problem.

In Setup > Video Output Configuration try changing the Data rate to 8-bit. Also check the HDMI Sync setting to see if the alternate choice works better.

If the re-install you started with seems to have cured the problem, then continue entering the rest of your settings manually. I.e., do not use your Saved settings. If you still have no problem after re-entering all your settings then you may have had corrupted settings to start with.

As you bring up each Source, test it. If the problem happens with each Source but does NOT happen with the internally generated Patterns, then there's an HDMI problem on the Input side of things. This time test with the Source set to send 480p to the Anthem and see if only higher resolutions have the problem. Call Anthem Tech Support with the results.

What other changes are needed?


Ed

As mentioned in one of my earlier posts, it would be nice to have more options for configuring the measurement results with custom filters (peaking, high/low shelf etc. like the Tag AV192r ten years ago), maybe even to be able to manipulate the resultant curve (like the current Audyssey Pro) , an improved "front end" rather than one based on s-video would also be nice, you know, using HD instead of lower than SD. How about being able to see what's happening below 20Hz, as has been requested a few times on this forum. Multiple sub support (independent settings and measurement) with better bass management including phase check and settings (although this may be limited by the HW).
It's not as if any of the above is new technology, it has or is being done already.
The above are all SW based, and just need competent programmers... There are lots more possibilities, just look at some of the other kit that's available, but let's just stick with the simple things for the moment.

Dolby volume is a joke, I'm amazed that anyone is actually using it as it just distorts the sound.

Read Me - v3.xx Upgrades.txt 15k .txt file
I think the 50v/D2v 3D is a great product. It meets all my needs and with the latest firmware has very few bugs. With the new will come more bugs, and perhaps another 1000 pages to read here. Right now I'd rather enjoy the stability of a mature product as evidenced by the recent quietness of this thread (except for the "upgraditis" itches).

Welcome to the club Chris,

You can also use the INFO page in this menu to see what video format is being input and output:

Be aware that the setting area you enter by pressing #7 is for the source you were or are currently viewing

The video processor could be changing the color space and format to something your TV is not happy with. Using AUTO for color space, format and data length is not a good idea. Unless you have the "3D upgrade" installed and set to bypass each source "OUTPUT = THROUGH", you need to become intimately familiar with what each setting does and how your TV reacts to them.

They never jumped on the 3d craze they gave pass thru and at that stage you may as well feed only audio to the box for all your 4k video (whatever that maybe). Why would you push for 4k pass thru if you want to push for something push for 8k or you will be back here in a year.

This crystal ball I have made the Pentium 100 I bought in 1995 upgradable until to day. I just need a new mother board, ram, power supply, video card, Blu-ray burner, ssd drive, sata drive and my old case did not fit all the new technology so a new case and there future proof. It was my 286 in 1987 that I made the mistake on. This is a way of life for technology and if you can't afford the high end game get out of it now when you can. My wife would love me more if I could biggrin.gif.

You may see a new video board but bet it will not be the great price that we got for 3d pass thru. I would like an 8k video processing board (not pass thru) with top of the line processor please. That is when they come full circle with the design of the processor and it has come into its own, if not it will only be the best for 30 seconds. Look at the life span of gaming video cards. A modular avpro little your desk top just slap in a new video card and you are ready to go.

Hi there - I'm trying to get an iTach IP/Serial device to work with my D2v. I have had a URC MSC-400 working over Serial for a few years now, and it's been flawless (I had to program the serial codes myself from the spreadsheet), but it's only one-way. Limitation of the URC system.

I've been converting over to Roomie, which has been solid for IR devices (using the iTack IP/IR devices), using Roomie to control the iTach. For IR devices, I've had no problems. But I can't get the iTach IP/Serial to work with my D2v.

I've tried baud rates from 152K down to 1200, no luck. I've tried N/8/1 and N/8/2, also no luck.

The serial cable I'm using is the same one I use with the Keyspan to update the D2v, so I'm assuming it should be fine and is the proper type? The main difference is the iTach has a serial port, so I'm using the serial cable without the Keyspan in this case.

I can fall back to IR control, but I'd really like to get serial working again, and have the two-way feedback.

Thanks in advance for any help, guidance, or ideas on diagnosing!

FWIW, I got it working. I had to set the iTach to 115200 N81 no flow control. I then used my custom plist, or you can download the one posted in the thread and synch it with Dropbox. Seems to be working for power, volume, and source selection, will test later with the various menus.

Now I just need to get my Sony VPL-VW60 working over IR (although maybe I should try serial?), and get my HomeSeer fully integrated, and I'm good to go!

Haven't been following this thread for a while - but I have a D2v, and was wondering if the HDMI upgrade is out there for general availability (for 3D/HDMI 1.4x) and worth it? And what I should expect to pay, roughly? I don't do 3D, but figured the HDMI handling should be improved.

Any thoughts?

In addition to flow control, the other usual culprit for problems with RS-232 control is whether the controller wants the RS-232 settings in the Anthem set to ECHO BACK input sent by the controller. I.e., is the controller expecting to see just the responses to each command sent or the combo of the echo of what it sent followed by the responses. Change this in the RS-232 part of Setup. Be sure to turn echo back OFF before trying to do ARC setup stuff. For firmware installs, the install must be preceded by a Reload Factory Defaults in the Anthem, which, among other things, also leaves the RS-232 Echo turned off.

Did you already check to see if you are entitled to a reduced price upgrade? If you are I would say it's worth it, even if you don't use 3D, for the increased resale value and updated HDMI handling as you say. If you have to pay full price for it then maybe not.

And what about the software that ran on your "Pentium 100"... you can still use that today!
Windows 8 will even give superior performance on old hardware.

Why is everyone focusing on hardware, it is the D2v software development that has not moved forward. Done properly, the HW can last for many years with SW/FW introducing new features, functions and performance improvements, it is this area that Anthem do not seem to be exploiting. Or maybe they are and have great plans for the future, but there does not seem to be any evidence to this effect.

Windows 8 does not run on a Pentium 100 .... not enough ram slots. It was only tongue and cheek to begin with and software will never fix hardware short falls. The sigma design VXP may never process a 4320P signal if the standard does remain at 16:9.

Regards

EDIT:

I should have added it does do a excellent job conditioning and feeding it to my 1080P. When I do get an 8k set than maybe I will still be sending this processed 1080P to the set and let it do the transformation. It depends what they come with when they are released. 4K I can skip in the blink of an eye and not regret it.

I have the same issue with headphones. Terrible hiss on all the headphones I own. Auido-Technica, Grado and Sony. It is disappointing that a product at the level of the D2v can't deliver performance that even a basic receiver has no trouble with.

I was just echoing the fact that noise starts when the digital source processing is engaged (source and display turned on, PCM indicated, no disc playing). It is virtually silent until then, so I don't think it's noise on the power line (dimmers have no effect on it). Turning off the source or display does not stop the noise once it has started.

I didn't say that it does, please read my post more carefully.

The fact is, most programmable devices benefit from software and/or firmware upgrades in their lifetimes, the D2v has had few upgrades (debatable if it has had any at all) of this nature despite being on the market for so long... this is what I am commenting on and so far nobody has said anything to indicate otherwise...

Just got my Anthem AVM 50v 3D and am using Oppo BDP 105 for blu ray. I don`t want over processed video so I want to use Oppo processing only, how do I set Anthem to pass through? Alot of settings with the Anthem if any of you have any set up tips, that would be appreciated. I have Paradigm Signature 6`s and C3 for cc I think ARC set my front and center crossover to 60hz, that seems a little high to me. When I adjust that down to say 40hz do I have to set sub crossover to 40 as well, or does sub crossover bypass take care of that?

Sounds like you need to read a bit here and the manual, than tinker with your settings, once you know them, let your anthem than your player process and see what you like better for your setup.

Bottom line is if you read a bit here you will know NEVER MESS WITH THE ARC SETTINGS when done right (read here 1st post and your manual) this is something that is perfect that you should not mess with.

Totally agree that the software definitely lags the hardware. You would think at least disable source would be in the options. Was not indicating anything to the contrary in my OP. What I was saying was to think that this hardware will process 4k is a bit beyond the original purchase agreement. We all know technology advances and I for one hope my last anthem with be 8k video with HHHD audio. biggrin.gif

post #40372 of 42717
Thank you man! That`s just what I was looking for. I know I need to read the manual more, I am not the techiest of guys and the manual talks over my head some. According to Bob`s attachment the actual disc is pretty important for serial number syncing. I have had problems with PBK (not recognizing sub and mic) I have gotten a new computer and instead of loading the PBK disc I just downloaded newer version of PBK from Paradigm and wondered why it didn`t work. Thanks to Bob and yourself it sounds like I need to use disc first then download newer version of PBK. Thanks a lot to both of you.

From the setup menu SOURCE SETUP - for each source you have assigned to the Oppo (eg: DVD1) set the video output mode to THROUGH.

Thanks man. I PBKed my sub before ARC and the chart is the best I`ve seen. Hardly any delineation from target line. Am I right when I say less video processing the better? Any other tips for set up other than ARC the hell out of it and leave it? Maybe with Oppo settings.

DSD playback question: Thinking about purchasing a DSD capable DAC. Currently my setup is as follows: HTPC FLAC files in J. River media center (USB out) -> EMU 0404 (analog out) -> Anthem D2v (XLR out) -> Emotiva XPA-1's -> Martin Logan Spires. I have read up on some of the DSD capable DACs and want to ensure that I will be able to play the files through the Anthem D2v.

My main question is since the D2v does not process any DSD files does the DAC that I purchase need to have a dedicated pre-amp? I am wanting to go DSD directly to analog to the D2v. The setup would look as follows: HTPC (J. River DSD files played via ASIO drivers) (USB out) -> DSD DAC (balanced XLR out) -> Anthem D2v (etc, etc).

So basically if the DAC is outputting through balanced XLR's that should be an analog out correct?

Sorry, I know this is a bit OT but it is my favorite topic

You pretty much have everything setup correctly for playing hirez stereo music.
You would substitute a DSD capable DAC for the EMU0404. You can store the DSD files with your FLAC files and JRiver will stream both correctly.
The best way to set this up is accessing the music computer files via ethernet or USB to the DAC using Jriver, Then output to the D2v via balanced or analog cables.
The D2v output is via balanced or analog to your amp.
What ever source you use in the D2v , I use 2 chan balanced, you should be using Analog Direct as you do not want another ADC to DAC conversion.
The D2v will act as your preamp. Anthem has told me that the D2v volume control is not a digital control so no added distortion.
Playing hirez stereo you really do not need ARC or a subwoofer.
If your looking for a reasonable DSD DAC you might consider the TEAC 501 or the Mytek 192 stereo. I use the Mytek an it is fabulous.
It automatically switches from any Flac bitrate to DSD without any intervention.
I store the files on an external HDD connected to an optimized laptop connected to the Mytek Stereo 192 DAC
Using the ASIO drivers it is capable of playing double DSD (5.6 mHz ) music files.
There are many DSD files available for downloading with more being available everyday.
Or you can rip DSD files from SACD discs and eliminate the distortion from the optical player.
Using JRiver allows you to view and control your library with a tablet or smartphone.

You can find out much more here. Computer Audiophile Forum

That pretty much answers my question. I guess I just need to find out if the TEAC 501 supports ASIO 2.2. I will be using J. River as a player and I want to bitstream from the HTPC to the DSD DAC without any PCM downconversion. I know the mytek supports ASIO 2.2.

Call Anthem Tech Support. Your unit may need service.

Again, if there is hiss on any of the outputs, then something is wrong. The USUAL reason is external interference (RF, not ground loop). But if you've already done what you can to eliminate that as a possibility, then your Anthem may need service. Components do fail in all electronics.

There is nothing to fear from letting the AVM 50v/3D do video processing.

If you have the OPPO putting out 1080p video, and have the Video Source Adjust menu in the AVM 50v set to default values for the Input and Output adjustments, then the AVM 50v is not doing anything except for color space conversion math as necessary to match your specified output format to the Display. The OPPO has already done all the heavy lifting, and so there's no work for the Anthem to do.

Modern video processors do things only when there is work to be done.

Even if you decide you want to use Source Direct output from the OPPO, the video processing in the AVM 50v is as good as it gets.

This sort of testing can be a little misleading, as there are situations where the output is automatically muted, such as when the Anthem does not think there is a valid digital input stream on the input. Get in touch with Anthem Tech Support. They may be able to suggest some tests to nail down if this is an internal problem (unit needs service) or some form of external interference you've not yet identified.
