Simultaneous analog and digital video output?

Does anyone know for sure whether the integrated DVI-I port on a MBP can (or cannot) generate analog (VGA) and digital (DVI-D) signals simultaneously?
P.S.
If you are curious why I am asking this question, it is because I would like to have my MBP displaying (same data) simultaneously on the Apple HD Cinema display (DVI-D) and a VGA projector in my office. And if the MBP can output both signals at the same time (i.e., using all pins on the DVI-I connector), then the following clever DVI-I to DVI-D/VGA splitter would do the trick:
http://www.pccables.com/cgi-bin/orders6.cgi?action=Showitem&partno=01780&rsite=f .01780
I am assuming if this works at all, then the MBP will dumb down to the resolution supported by the VGA projector on the DVI-D output (just as it does for the internal display).
Tx, -CR

Depending on which version of the MBP you have, this may work under Windows. But it does not work under OS X. There has never been driver support for it.

Simultaneous analog and digital waveform read with PXIe-6361 and BNC2120 ?

Hi there,
I am trying to collect both analog and digital signals from a PXIe-6361 linked to a BNC2120, using the attached VI. I am running Labview 2011 64bit. This is the first time I am working with digital input. On the 2120 board, I have the digital input BNC cable connected to User Input 1 and wire between the screw terminal of UserInput 1 and the P0.1 (Digtial I/O) screw terminal.
I have two questions related to this:
1) When I try to run the VI in its current state, I get the following error:
Error -89137 occurred at DAQmx Start Task.vi:3
Possible reason(s): Specified route cannot be satisfied, because it requires resources that are currently in use by another route.
Property: RefClk.Src
Source Device: PXI1Slot2
Source Terminal: PXIe_Clk100
Required Resources in Use by
Task Name: _unnamedTask<6>
Source Device: PXI1Slot2
Source Terminal: None
Destination Device: PXI1Slot2
Destination Terminal: RefClockInternal
Can anyone point me in the right direction for troubleshooting this?
2) I would like to combine my regular waveforms and the digital waveform into one array which would then be written to file. I can't figure out how to combine the two different waveform types...can anyone give me a hint on this?
Thanks for your help,
Claire.

Hi ClaireJ,
Sounds like a reference clock conflict. This KnowledgeBase (KB) talks about this error when using simultaneous sampling. Also, might want to check the device routes in Measurement and Automation Explorer (MAX) as discussed here. Finally, if you are routing your PFI line over a RTSI connection, this error can occur. This KB discusses it.
As to your second question, this post should help.

Airtunes - Analog and Digital output at the same time?

Howdy,
This may seem strange to ask, but can the Airport Express output audio in digital and analog formats at the same time? Is there a strange splitter cable that could do this for me?
I recently learned that most AV receivers with digital inputs cannot output digital sources to their analog zone 2 outputs. The usual work-around is to connect their digital sources to the receiver by both analog and digital cables.
Mikael

I just learned the same thing. Does connecting the digital and analog connections to your reciever work ? Did you connect them to the same source or assign different sources for each? Thanks,

Analog to digital video

Does anyone know the quality difference between the analog to digital video converter in the Canon Elura 100 camcorder vs stand alone converters. I own an Elura and am converting older Hi8 video to my Mac and it is hard to find specs on these devices regarding resolution, sampling rate, etc. Has anyone noticed any problems with video converted using the Elura ?

Faedo,
Cheapest ways:
1. Do you have a DV camera? If you do and it has "digital in" then you can take the output from your VHS player, route it through the camera and into your PC. The manual would explain if it is a feature.
2. Secondly, search ebay for Dazzle Hollywood DV Bridge. This is a hardware converter that takes the analogue and does the conversion for you.
Good luck.

Enabling Simultanious Analog and Digital Audio Signals

My apple TV runs through a Yamaha receiver. It is hooked up with component video and digital audio cables. I also need to hook analog audio to my receiver so it can play outdoor speakers through zone 2 (which only recognizes analog signals). Zone 2 does not work when I hook both digital and analog cables. Called Yamaha and they said to look for a setting on Apple TV that enables simultanious analog and digital audio signals. Does anyone know if/how this can be done? Or any other way to make the analog zone work without losing digital on the main zone?

AFAIK, the analog audio on the ATV outputs all the time. The audio output setting in the ATV just determines whether the digital output is Dolby or PCM. Try turning off Dolby in the ATV audio settings and see if that makes a difference. If not, the problem is probably elsewhere.

USB for analog to digital video input?

I have a USB-based Analog-to-Digital video converter that I used when I had my PC, for transferring old family video tapes to digital to burn DVDs.
Can I use this with my Mac with iMovie 08), or will the Mac only accept digital video via a Firewire input?

no, you can not use that device, because usb-devices need specific 'drivers', which in most cases are of no avail for Mac ..
but...
many harddrive-camcorders are connected via usb, and DO work with Mac..
if a device has both (miniDV camcorders), the video is only imported via firewire, the usb-connection is only in use for stills, those devices allow to record ...

One long repeating beep and no video output

Sometimes when switching on a system build with KT6 Delta , I get one long repeating beep and no video output. The problem usually is solved if I unplug the monitor cable from the vga card and plug it in again. Still, I am thinking why does this happen since the cable seems to be connected fine?

1 Beep: DRAM refresh failure
Explanation: The system is having a problem accessing the system memory to refresh it. Refreshing is done on all system memory to keep its contents active.
Diagnosis: This code usually means a problem either with the system memory or with the motherboard itself.
Continuous Beeping: Memory or video problem
Explanation: The system is producing constant beeping in no specific pattern, or a fast "ringing" sound.
Diagnosis: This is usually caused by a problem with the system memory, or possibly the video card. The memory is more likely--the system complains long and loud if it can't find any usable memory, as there is no way to even start the boot process when this is the case. The motherboard itself could also be the problem.

Start by looking around the examples that ship with LabVIEW (if you are
using LabVIEW).
Also look around zone.ni.com for general data acquisition information &
examples. A good site.

MBP video out to TV using DVI - both analog and digital?

I have a Macbook Pro 10.6.4 2008 Model with details are below on graphics card and display options. I am trying two hookups to televisions which may or may not be possible. Can anyone tell me if my DVI output on the macbook pro is capable of delivering an analog signal to my old sony tube tv with component inputs? Second part of my question is do I have the right dvi cable. I purchased a cable with 24 + 5 pin. This cable does not produce a picture on my analog or digital television. Just snow on the analog and no input on the digital. The cable that came with my macbook pro is a DVI to VGA converter and seems to be an 18 + 5 pin plug....with a few pins missing in the middle. Should I buy another cable with the 18 + 5 pin DVI to component or buy a cable to connect the supplied DVI to VGA converter - VGA to component. Please help I'm confused on many fronts.
Thanks

I made an account and am replying to this because i have the exact same computer as you and i was also at best buy at around 3pm wondering the exact same things you were! The DVI port on our MacBooks are different than the standard DVI ports. Freaking weiiiiiiiiiiiiiird! Get out of my head!!!!
I ended up buying a VGA cable and using the converter that came with my MBP because the DVI to VGA cables at Best Buy had a different VGA than what the MBP has.
Our goals were slightly different though, I wanted a cable so i can connect the MBP to my Toshiba 42inch HDTV. VGA works but doesnt support 1080p, only 1024x768, which is not a fullscreen resolution. So i will be returning the VGA cable tomorrow and looking for a VGA to HDMI cable, if that exist.
So, to answer your question, YES, buy a cable that has the same ports as our adapter, or just use the adapter that came with the Macbook.

Producer consumer with analog and digital inputs and outputs

Hi everyone,
I am working on a control system program for some practical test work. Currently I am working on the data acuisition component of the Labview program. My architecture is produced-consumer loops with a que. My system will have analog inputs, analog outputs, digital inputs and digital outputs. It's not a time critical sytem, but I would like all of the data acquisition to be synchronised. I have attached my program as it is at the moment. I am having trouble getting all of the data into the que since I have two data types. Also, I'm not sure if i've synchronised the four read/write sequences correctly. I would greatly appreciate if somebody could take a look at my program and give me some advice. Thanks in advance.
Solved!

control_v2_DAQ loop.vi ‏46 KB

Robert, the specific error that I get is:
Error -200462 occurred at DAQmx Start Task.vi:6
Possible reason(s):
Generation cannot be started because the output buffer is empty.
Write data before starting a buffered generation. The following actions can empty the buffer: changing the size of the buffer, unreserving a task, setting the Regeneration Mode property, changing the Sample Mode, or configuring retriggering.
Task Name: Heater testing lab digital outputs
This error occurs at the 'DAQmx write.vi' function. I just want to sent one sample per second, for each channel. I would like the producer and consumer loops to each run once every second.
I have attached part of my code with just the data acquisition and writing. Any help would be greatly appreciated.

Is simultaneous use of HDMI and Component Video outputs possible?

I want to split the Apple TV video output to drive my main plasma TV when desired, but also to a smaller LCD TV for more frequent use to show what songs are playing thru Apple TV - as this is my common usage. It seems that with the HDMI cable plugged into the Apple TV, it does not drive the component output. Is there some way to do this or do I have to go for an HDMI splitter?

HDMI takes precedence over component, so you can't use both at the same time. if HDMI is connected it will use that.

No digital video output from XVR-300 in Ultra-45

I am switching from solaris 10/x86 to sparc. I have a new Ultra-45 with XVR-300 graphics adapter. It's running Solaris 10u4. The system was ordered as a standard configuration from the catalog.
The XVR-300 graphics adapter currently produces no digital output. My Sun A1240P0 24" monitor reports no signal on the DVI input. That is, there is no digital output at power on (boot ROM), during Solaris boot (terminal), nor after Solaris finishes booting (X).
The graphics adaptor uses a connector with two video outputs, and comes with a splitter cable with two DVI output connectors. I get no video output on either. The DVI cable I am using is the one that works when connected to the graphics adaptor on the old system.
I added a VGA adapter plug to connector 1 of the splitter cable, and was able to get an analog signal to drive the display via the VGA input connector.
The manuals for the Ultra-45 and for the XVR-300 make no mention of analog vs digital output. They both just say to connect the adapter to the monitor.
Since I can get analog output from the SVR-300, the card is basically working. The DVI cable and the monitor's DVI input work with another system. The only variables are the digital output from the XVR-300 and the splitter cable. (The splitter cable's analog signals work.)
How can I activate digital output and make it the default?

Converting analog to digital video

Does anybody know a cheap way to convert analog video (from a VHS) to digital video that can be burned on a DVD? A converter box is probably my best option as I have no digital camcorder, but I was looking for one under $150. So far the only ones I can find send the analog signal to the computer, where it is converted to digital by software. This would be fine, but the software is Windows only. I either need a converter box that converts the signal within the box and sends a digital signal to the computer, or one that comes with converting software for Mac. Preferably composite video (yellow, red, white), and preferably something that uses firewire, although if I have to I can use USB
Thanks,
Tom

Not sure what you mean by "breaks up in places".
In iMovie4, the maximum clip size is 2 gigabytes. When importing from a camera or converter, iMove will just start a new clip ever 9 1/2 minutes (2 gb), but you don't lose a single frame.
If you're getting irregular breaks, including the loss of video (may be hard to tell, if it's only a frame or two), you either have a cable problem (maybe just not plugged-in securely) or a VHS tape that is a bit out of synch. For that, you might need Time Base Correction, where the hardware will basically ignore the synch data on the tape and replace it with it's own. There are VCRs and video converters that have TBC built-in, but they're more expensive. There are also separate pieces of gear that do only that. I dunno whether digital cameras are available that do this.
First, I'd see if it happens with other tapes, then try another VCR, before spending megabucks on more gear.

In iLife08 what is best setting to convert avi 720 and digital video 1080i

What is the bottom line for best quality for 720 p TV.
1.) My import is digital video 1080i to i Movie 08 (full quality)
What should I use for sharing on AppleTV
- the preset Large (which is 960x 540)
- or some custom setting 25 fps at 1220x 720? ( H.264 display dimensions at 24/25 fps is 720p (1280x720) ) - or what should the setting be??
2.) Have Windows avi older 720 *480 video, what is best setting to convert this for Apple TV? The 640 setting on QuickTime premium is not very good
Thank you so much. Peter

Your best option if you are using NTSC footage in imovie is the export to/movie large (960 x 540) at 30 fps, the resolution won't go any higher and still work on the tv. Don't even think about changing the framerate to 24/25 fps, even though you'll be able to export to 720p (1280 x720) changing the framerate will make your video jerky.
If you are using PAL then yes you could export to 720p (even though the specs say 24 fps, 25 fps does in fact work as well), you could try a few tests yourself but I've already done them and IMHO there is so little difference between 960 x 540 and 1280 x 720 that it isn't worth messing about setting up and trying several manual exports to get the best results when you can click one button and be done.
So far a AVI conversion is concerned, I'd try mpegstreamclip, but saying that I can't really be sure. AVI is a container not a codec and I would need to know what codec is actually used inside the container to answer your question properly (Quicktime may tell you though). The problem with AVI is that it is simply so old (even microsoft abandoned it over 10 years ago), unfortunately in a small number of cases some of the codecs that were used in AVI are simply no longer able to be converted. Probably not so likely but at least you are warned.
