If you plan to manage more than a screen or two, you will probably need some way of accessing them and changing their content remotely.
There are two popular ways to do this. First is by using a subscription-based service (called software-as-a-service, SaaS or cloud-based signage),
where you own no infrastructure and pay a company a monthly, quarterly or annual fee for access to all the technology needed to manage your signs,
usually via a web-based portal you would access with a web browser. Alternatively, you might prefer to purchase the server software and hardware
and manage the system yourself. This is commonly referred to as using a self-hosted or premise server solution.
Generally speaking, if you want every screen in a given venue to show different content, you will need one dedicated media player per screen.
If you plan to install multiple screens that show the same content in a given venue, you may be able to use only a single player, and use video distribution
equipment to split and distribute the same signal to multiple screens. Note that we haven't included the cost of any distribution equipment
in this estimate calculator.
Site surveys are usually performed by the company you contract with to do your screen installations. A technician will go to each site, study
the floorplan, note the location of required power and connectivity sources, and take notes and photos to attach to the installation plan. Generally speaking,
if you don't own or operate the venues you will be installing into, you should perform site surveys a few weeks before your planned installation date.
Whereas normal high-definition (HD) content is either 720 pixels tall (720p) or 1080
pixels tall (1080p), ultra high-definition or UHD content has about four times as much
data, with a typical resolution of 3840 x 2160. It's often called 4k, either because
of the nearly 4,000 pixels width of resolution, or because it's about 4 times the data
of a conventional 1080p stream. While 4k content can be exceptionally sharp, it requires
a very large amount of storage space, uses a large amount of transfer bandwidth between
the player and its central server, and needs more expensive high-speed hardware and
UHD-capable displays.
The vast majority of digital signage applications do not benefit
from using 4k content. Note that smaller screens are generally not available in
4k resolutions, so we ignore those in the estimator.
