IP/VC 3540 MCU: How to eliminate the local image on the local endpoints?
FACT: When creating a multipoint call using an MCU, the local image has been sent to the local endpoint which may result a slow connection since the video packet were sent to the origin.
QUESTIONS:
1. How can we prevent the local image to be sent to its original endpoint?
2. If it does happen, does it consume more bandwidth?
- In a symmetric conference that is setup to allow for 320K video would allow for 320K in and out. It does not get divided in half to produce 160K in and out.
- The EMP has additional features above and beyond the RMM. You can see if the EMP is registered with your MCU by going into the administrative interface of the MCU and clicking on the Registered MPs tab. You should see both the MCU MP and EMP that is your system is using.
- In a continuous presence conference 5 people would need to be in a conference in order for the local image to fall off the screen. This does not really eliminate the participant from the conference; it basically masks their image from being sent since they are not one of the primary speakers. If that person does talk the will show back up in the one of the four squares.
- The only reasoning that I could possibly give for the local image looking good on the Polycom is that it may be sending back the original image to the local party. If you were to have another unit dial into the conference how does the image look?
- Without the Audio Transcoder card you will only be able to handle G.711 Audio. Advantages of the Audio Transcoder card are that it allows you to transcode from G.711 to the following audio codecs.
The IP/VC 3540 audio transcoder modules for the MC03A and the MC06A provide the following features:
= Translates to G.722 codec
= Translates to G.723 codec
= Translates to G.728 codec
= Translates to G.729 codec
= Translation for up to 30 ports simultaneously

How to eliminate the "Ping" sound when starting and stopping videoing
How to eliminate the "ping" sound when starting and stopping a video on iPhone. Thanks.
I asked my friends on Facebook and one came up with the answer... I just had to flip the little "ring-silent switch" on the side of the iPhone to cut the "Pinging" sound! There's probably another way but this works!

How to eliminate the thumbnail picture from a .TIFF picture?
I apologize but could not think of a more suitable forum to ask the question - if someone has an idea for a better place, I will appreciate.
When I create a picture with my (Nikon) camera in the TIFF format, it appears that the picture file contains in addition to the full blown picture, a reduced version of the picture, something like a large thumbnail vrsion of the picture. I found it by trying to create a PDF file of the .TIFF file - Acrobat created a two page file, one with the full picture and one with the reduced picture. It looks that I can't tell the camera not to embbed the thumbnail version.
So my question is, from someone who is familiar with the .TIFF file format, how to eliminate that thumbnail version from the .TIFF file. Must be somewhere (hopfully one) location in the file that when modifying it it eliminates the thumbnail picture from Acrobat's view into the .TIFF file.
As to the question why not simply erase that undesired page from the PDF file - the answer is that I actually going to assemble many (hundreds) such pictures into one PDF file. Acrobat will put all those pictures such that each main picture will be followed by its own thumbnail and therefore I will have to select manually each single thumbnail page before erasing them, extremely tedious. If I could process it at the individual .TIFF file as describrd above, I could easily write a program that does this modification to all my .TIFF files with one invokation.
Many thanks,

Each time I start iPhone or iPad I get a message: 'Password required/ Enter the password for the CardDAV account'. Can anyone tell me what that is about and how to eliminate.
Also this began happening the same time my Yahoo mail account was hacked which resulted in my mail program (on mini) to fail. It crashes on startup.
ThanksThanks Steve that did it on my iPad. It was the yahoo account. Im beginning to think that Yahoo is dangerous. It was the hacking of my Yahoo mail account that started these problems. My mail account on my mini still does not work. I posted the problem here and got real professional advice but to no avail it still doesnt work and I cant re-install the OS because Im in China and their Great firewall keeps the net too slow.

How to eliminate the alarm "Client License Limit Exceeded" in Lookout 6.0.2?
There are 18 Run Time Only Servers, with no clients, running the same application. Right after the installation of the Lookout 6.0.2 software this alarm didn't show up, but after some time it does in all the systems. It makes not too much sense to me because there are no clients at all, thus no client license was purchased and entered/registered.
How to eliminate this 'false' alarm?
Any help will be appreciated!The design is complex. Within the features, each system collects data in .csv format, and once a day moves a copy of the data collected to some place in the network. Also the systems print to file the events and alarms (once a day as well), then they are copied out with the database to the same place in the network. This folder containing the database and the events-alarms in the network is for other engineers to analize, make calculations, projections, etc. It is weird for me and for the others to have this alarm every day in the events-alarms files of each system.
Each system is independent, doesn't need to have connection with the other systems. There are no clients because the database collection is enough for us. The systems are VERY STABLE, no need to trouble-shoot (remote access), or even checking how they are working. Truly, Lookout shows a good performance with this application. By the way, the application is too extensive, complex, many different things are controlled and monitored, many different communication protocols are used: OPC servers, Serial connections, etc. General speaking, the overall result is excellent. This little, no-reason alarm is the only problem: "Client License Limit Exceeded".
I'll really appreciate any suggestion regarding this issue. -
How to eliminate the noise from the stepper motor
I’m using stepper motors to move a traverse on which a hot-wire anemometer probe is mounted. When the stepper motors are turned on, they induce noise on the analog signal of the hotwire anemometer, or of any other transducer, at multiples of 120Hz.
The stepper drives are P41 Series made by American Precision Inc. The P41 Series contains a power supply, a motor drive and a logic controller. The logic controller inputs are optically isolated and utilize the 5 VDC supplied internally by the drive.
An NI 6251 or NI 6024E DAQ card is used with LabVIEW to send digital output signal to the logic controller in order to step the motors.
The AI input channels of either NI 6251 or NI 6024E DAQ cards and LabVIEW are used to acquire the signal of the hot-wire anemometer. Different DAQ cards are used for the data acquisition and the stepper motor control and the noise is transferred through the laptop to the data acquisition card (analog signal).
All cables are shielded and the noise was confirmed to be conductive and not radiative.
There was no difference when measuring the analog signal with Differential or RSE.
As a test, the leads from to the drive’s logic controller were connected to the AI input channels in order to check the magnitude and frequency of the noise flowing to the DAQ card and were found to be 5 V peak-to-peak at 60 Hz.
Please let me know if you have an idea on how to eliminate this noise.It sounds like you have a ground loop issue. If possible, try totally isolating the stepper controller from the data acquistion AI more than you already have. This could include any of the following:
Ensure the optoisolation on the control lines fully separates the power and ground of the digital output and stepper input.
Use different grounds for the stepper power supply and the DAQ power supply/computer. Isolation transformers can help here.
Use lower inductance lines for the stepper controller. This will reduce the movement of the ground.
I suspect you have probably been over the above, so you are left with filtering the noise out of the signal. Since it has high harmonic content, a simple low-pass is unlikely to work well. Your best bet is probably to characterize it and use some sort of Fourier filtering. If the relative sizes of the harmonics are always the same, you can take the Fourier transform, find the height of the fundamental, use this to calculate the sizes of the harmonics, delete them from the Fourier transform, and do an inverse Fourier transform to recover your signal. Alternately, you can use a series of narrowband filters to remove the noise, although this will also remove any signal at the same frequencies. It is better if you can improve your circuitry to remove the noise.
Good luck. Let us know if we can help you more.

How to eliminate the extra line in the emaildody while using EMAIL_PLAIu200BN
Hi Experts,
I am using EMAIL_PLAIN option for extended notifications via SWNCONFIG. In the body of the email a horizantal line is getting displayed on the top of the email body. How to eliminate this line??
Thanks and Regards
Srini..Hi,
In tcode SE80, select BSP Application and put SWN_MESSAGE1 in text field. So, you can see plain_indiv and plain_multi HTML. If you click-on this you can see the layout and the standard horizontal line.
If you want to change it, you have to copy this BSP and create a Z one and change the layout. Now, in tcode SWNCONFIG, go to Message Template and change BSP-URL.

How to eliminate the column data which just has a special character
Hello All,
I working on a query which will query the table and returns only the meaningful data. In the table, I have the data like this
ID SearchWord
1 20A-1
2 Mainline
3 %

5 Little Rock, AR
When I select the data from this table, In the result set, I don't want to see '%' record, '-' record. If a SearchWord contains the special character along with other alpha numeric characters its fine. But if a record contains only special characters,
I wanted to eliminate them. How can I achieve this?
Thanks so much for all your help.SELECT *

WHERE SearchWord NOT LIKE '%[^0-9A-Za-z]%'
AND SearchWord LIKE @Yourparameter

How to eliminate the space between two analysis in the Dashboard?
Hi All,
I have created a Dashboard which contains 12 analyses arranged vertically. When i see the report in the dashboard section it contains some standard space between each analysis. So it looks like separate separate analysis arranged in dashboard. But i want it to look a single table is it possible by reducing the space between every analysis? If possible please let me know how to achieve this in clear manner.
Awaiting your valuable responses.
Thanks in Advance
ThenmozhiHi,
Yes,try to adjust the analysis view (table/pivot/chart view )Formating option...
FYI: try to align formating left,right,top/bottom padding and also try to reduce the width and height..
Please refer the below

How to eliminate the delay on my X-Fi Surround 5.1 external sound car
I just bought is. I finally am able to hear my keyboard through my headphones running from my computer.
Only problem now is the delayed response. I hit a note and 2 seconds later it responds.
Any ideas on how I can get the sounds to some through in real time.
I have a 2 sided stereo plug. One end going from the headphone jack on the keyboard (KORG triton)
the other end is pluged into the line in port on my <span class="mainlink">X-Fi Surround 5. sound card.
I have elminated the keyboard as cause. Ive tried adjusting sampling rates and I still get the same delayed response.
I originally had the audigy 2nx which never had the issue.
Any help would be greatly apreciated. Thank you.Hi Fabryc,

This happens when I get an email with a link attached. Also, every single time I open up the NEW version, it defaults to the "welcome to Firefox 4" page. Is there a way to make it stop doing that too? Did I just download the new version too soon, before the bugs were worked out?
Version 3.6.16 is opening....as it did when I clicked the link in your email message to me about this situation. The upgraded version (Firefox4) sits in my dock and the old version opens when I click on a link.

When I burn my iDVD there are several times it skips (hesitates) during the show. I have 431 shows in the show.
Any suggestions on burning a clean copy?Thats the problem with creating slideshows in iDVD. Slides in such a slideshow are considered to be Chapters and a Track can contain a maximum of 99 Chapters. Early versions of iDVD only let you use 99 images in slideshows. Newer versions let you use more images by linking Tracks together. The problem is, many/most set top DVD players will pause/freeze on Track changes - thus the hesitation you see after every 99 images.
The only way to avoid this is to create your slideshow as a movie in iMovie, or use a commercial program like Boinx's FotoMagico (that I use) or Photo to Movie that others here use.
