Viewing
videos is a processor intensive and hard drive demanding
process. Large video files require higher end machines.
To view videos we suggest the following minimum
requirements:

I
can't see the videos once they are downloaded.
In
order to see the videos you must have the correct
plugin and the correct codec installed. The videos
in this web site are QuickTime videos. Go to www.apple.com
and download the latest QuickTime player. The correct
codec should be installed along with the QuickTime
player. If not, you can download the correct codec
from www.sorenson.com. The codec we use is Sorensen3.
If you have installed (and reinstalled) the above
files then make sure your screen resolution is at
least 800x600 and your color depth is 16 bits (thousands
of color) or better. Slow machines (< 500 MHz)
machines may not play the larger videos correctly
due to the videos large size. The large videos require
a fast hard drive, lots of RAM, and a fast CPU.
Try the videos on another machine to see if you
need to upgrade your machine.

How
are the videos named? (Video Naming Convention)
The video list uses a naming
convention to allow you to search for the type of
video or animation you wish to find very quickly.
The naming convention uses a format developed by
the ASE and SCA. The file name uses the standard
ASE/SCA format so be sure to save the files in their
own separate directory or you will overwrite the
files of the same name. Each directory contains
the abnormality-severity text.
probe location
- probe view - echo mode
An underscore _ is used between
each parameter. For example, if the probe located
in the mid esophagus (ME) and the probe view was
a 3 chamber view (3CV) and the echo mode was pulse
wave doppler (PWD) the file description would be:
ME_3CV_PWD
The following table shows the naming convention
abbreviations and their meaning:

| Why
do the videos appear darker on a LCD monitor or a
portable computer? |
| |
| LCD monitors on
home desktop systems or portable computers have decreased
contrast when compared to CRT (big, old) monitors.
Because of this decreased contrast the videos will
appear dark. Try decreasing the ambient lighting
(view them in a dark room) and turn the contrast and
brightness on your monitor to maximum. |
| |
|
Why
are the videos on my Apple/Macintosh machine darker
than a Windows machine?
|
| |
| Because of the method
Apple/Macintosh's display images and videos, the images
and videos will be darker than on a Windows machine.
Try decreasing the ambient lighting (view them in
a dark room) and turn the contrast and brightness
on your monitor to maximum. |
| |
|
Why
are the popup videos not popping up or not playing?
|
| |
| The popup videos
(when you click the 1X,2X,3X,4X links) may not popup
correctly if you have anti-popup windows software
installed. While the anti-popup or anti-ad software
works on popup ads, it also prevents our web site from
popping up windows. Most of the anti-popup software
will have an exception setting which allows popup
windows to occur from a "trusted" web site.
Please enable this setting by adding our web site www.e-echocardiography.com
to the "trusted" section. |
