The "brain" in a digital signage system is the content management server. In digital
signage systems, the media players are retrieving instructions and content from a
central server. Producing files including these instructions for the media players
is a vital part of the tasks for the content management server. In this chapter I
describe a sample digital signage system created to show how to handle one in practice.
Screenshots from a demonstration system provide the reader with some basic knowledge
about handling of a digital signage system and what needs to be considered when choosing
among the hundreds of digital signage systems available today.
Various architectures for digital signage systems and how these architectures affect
the content management system are also discussed in detail. Finally the chapter includes
streaming experiments that the reader can do using freeware software. Various aspects
of introducing live streaming into digital signage systems are discussed along with
HDTV signal formats.
Chapter 8 contains 25 full-color illustrations.
The content management server is the heart of the digital signage system.
