Chapter 7 Digital Signage Broadcasting


This is my favourite chapter of the book. Here the bridge between the digital signage and the broadcasting technologies is built. Adding an element of broadcasting makes digital signage a fully featured new medium capable of providing any kind of non-real-time as well as near-real-time and real-time content to an unlimited number of locations. In other words, it has the potential of becoming the major consumer medium in the future. My intention here has been to show the difference between unicasting the way of communicating over the Internet and multicasting —the one point-to-multipoint way of distributing IP packets. Various alternatives of unicasting, including peer-to-peer solutions are discussed as well as different ways of implementing private multicasting networks.


Much attention is paid to the use of satellites to broadcast IP data nationwide as well as internationally. The satellite parts are a suitable introduction to this field for people that want to start using satellite multicasting. This chapter is really about linking the worlds of telecom and broadcasting together. It also shed light on the often-asked question about when to use broadband and when to use satellite.


Chapter 7 includes 37 full-color illustrations.
