What is Digital Signage in ITU-T ?

q Definition of Digital Signage in ITU-T SG16m Defined in ITU-T H.780 (Approved: June 2012)

n H.780, “Digital signage: Service requirements and IPTV-based architecture”

m A system that sends information, advertising and other messages to electronic devices (e.g., displays, speakers) in accordance withn the time of day and n the location of the display, or n the actions of audience.

m Contents and their relevant information such as display schedules are delivered over networks
