Making an WMVHD File
Only the ISHD can play WMVHD files. WMVHD is a compressed video
format. There are a variety of tools and formats for encoding WMVHD. You
can learn more about it at http://www.wmvhd.com/
What Is An MPG File?
MPG is short for
MPEG, which
stands for Motion
Picture Experts
Group, the
organization that
codified the
audio/video
compression scheme
used in the
Information Station.
The Information Station plays MPG files that contain digital video
encoded in high-resolution by an algorithm known as “ MPEG-2” .
Many encoding systems produce MPG files, but not all MPG files may
be played on the Information Station. Many MPG files are designed
for playback in a small window on a PC, or for transfer over the
internet. These MPG files are generally of very low resolution at slow
frame rates.
The Information Station is designed to accept MPG files encoded at a
resolution of 704 or 720 x 480 (NTSC) and 704 or720 x 576 (PAL).
The Information Station can play MPG files encoded at bit rates up to
15.0 Megabits per second
. Since higher bit rates equate to better picture
quality, we encourage you to encode your video at the highest bit rate
supported.
How Do I Make an MPG File?
The most important step in creating video for your application is to perform the
highest quality MPEG encoding of your source material.
Encoding professional-quality MPEG material is more of an art than a science.
The person encoding the material must be experienced and the hardware well-
chosen, so users deciding whether or not to encode their material themselves
should put a lot of thought into what would best suit their needs.
