Action/Title Safe Area
The Action Safe area is the area that's visible on most
TV sets. It's roughly defined as 90% of the image area,
which translates to a 720 x 540 rectangle centered on
an 800 x 600 pixel screen. The Title Safe area is a
subset of the Action Safe area; it's the area that's
likely to be visible on even the most badly adjusted
TV sets. It's roughly defined as 80% of the image area,
or a 640 x 480 rectangle centered on the Director stage.
(The official formulas for specifying these areas are
much more complex, but the 90% and 80% figures are commonly
used rules of thumb.)
Aspect Ratio
The ratio between picture width to picture height. NTSC
has an aspect ratio of 4:3 or 1.33:1. This ratio defines
the width of the video image as being 1.33 times wider
than its height. This ratio between width and height
will always be the same no matter the size of the image.
Content
Materials assembled to form a displayable message. Specifically,
media files and text that are created internally or
externally to FireSign Studio then used to convey a
message through FireSign Player on a display screen.
DVI
A computer standard for graphics display.
FireSign Player
Software/hardware package that generates the digital
message based on the information that you have provided
in the FireSign Studio. Each Player runs independently
and can be configured to present your messages on various
types of displays.
FireSign Server
Software/server package that coordinates the interaction
and scheduling for all messages and screens in your
environment. All Studio and Player components connect
to the Server via a network. Only one FireSign
Server is needed per installation.
FireSign Studio
Software application that is used to create, configure,
and schedule the message content for your FireSign system.
Format
The assigned pixel dimensions, aspect ratio, and orientation
for a Segment, Schedule, or Player. FireSign
can
accommodate
4:3H,
4:3V, 16:9H, and 16:9V and others. Formats can be added
and changed through the FireSign Server interface.
Hex Color Codes
Hex, short for hexadecimal, is a base 16 numbering system,
which mixes letters and numbers (0-9 then A-F), so that
a three digit number (in this case numbers between 0
and 255) can be expressed as a two digit number. Hex
values can be used to represent the RGB values of colors.
These numbers appear as 6 digit (or 6 place) values,
with each 2 digits representing the Red, Green, or Blue
values. For example, a green background would be (0,
255, 0) in RGB, and 00FF00 in Hex.
IP address
Internet Protocol address. The location of a particular
connection to the Internet, expressed as four series
of digits separated by dots. A computer connection registered
with a DNS has a domain name associated with its IP
address.
Media Item
Any single piece of media such as a video clip, image,
animation, or audio clip. One or more of these items
may reside in a Scene.
NTSC
The broadcast video standard used in North America (for
National Television Standards Committee, the group that
devised the standard in 1953). Other broadcast standards,
such as PAL and SECAM, are used in other parts of the
world.
Orientation
Vertical (portrait) or horizontal (landscape).
Pixel Dimension
The size of a computer display screen expressed in horizontal
pixels by vertical pixels (H x V, or 800 x 600, for
example).
Preview
Use this function to see a simulated Player output on
the Studio screen.
RGB Color Codes
RGB stands for Red, Green, and Blue. You can compose
any color by mixing various amounts of these colors.
Every color available to a computer can be specified
by choosing an RGB set of values. To specify a color,
select a value between 0 and 255 each for R, G, and
B. For example, White is specified by (255, 255, 255),
while Black is (0, 0, 0). Pure Red would be (255, 0,
0), etc.
Scene
A display of arranged media compromised of one or more
media items. Scenes may be thought of as the individual
unit to a Segment.
Schedule
An arrangement of Segments with start and end times/days
assigned.
Segment
An arrangement of Scenes. May also be thought of as
a linear "presentation", where a collection
of Scenes may be composed to serve a particular
audience, event,
or subject.
Transition
Selectable graphic effects that are generated between
Scenes.
URL
Abbreviation of Uniform Resource Locator, the global
address of documents and other resources on the World
Wide Web.
VGA/SVGA/Wide-VGA
A computer standard for graphics display.
