Chapter 8 - Video, IPTV, and Digital Signage Systems

Abstract

This chapter deals with video distribution systems, digital signage systems, and IPTV systems in building systems. The best example of enterprise video distribution is cable television where a service provider is distributing video programming to its customers. Within a building the video distribution network is distributing video and informational content. The content may be re-broadcast content from a cable television company but may also be advertisements, public safety information, archived educational programs, live video feeds, entertainment, and energy information. A typical deployment of video distribution in a smart building involves: digital television transmitted over a TCP/IP-based data network; digital video distribution that transmits and receives MPEG video streams; distribution and transmission of digital video in a broadcast, multicast or unicast mode; a media retrieval system, allowing authorized users to schedule and stream video programming on demand; management and reporting system; and inputs to the digital video distribution system. Digital signage is an application on IPTV systems that broadcasts content to a viewer (as opposed to static signs). Basic components of a digital signage system include displays, media processor and controller, management workstation, and content.
