2 Introduction q ITU is the United Nations specialized agency for information and communication technologies ICTs. m ITU-T: ITU Telecommunication Standardization Sector m ITU-R: ITU Radiocommunication Sector m ITU-D: ITU Telecommunication Development Sector q Standardization work is carried out by the technical Study Groups (SGs) m develop Recommendations (standards) for the various fields of international telecommunications q SG16: Multimedia coding, systems and applications n Question 14: Digital Signage Systems and Services W3C TPAC meeting sgkang-2

3 Overview of ITU-T Q14/16 q Establishment of a new Question for Digital Signage m Proposed to establish a new Question for Digital Signage Standardization in May 2012 m Approved by WTSA-2012 (Dubai, ) n Q14/16: Digital signage systems and services q First ITU-T SG16 meeting (Geneva, ) m Rapporteur: Mr. Kazunori TANIKAWA (NEC/Japan) m Associate Rapporteur: Mr. Shin-Gak KANG (ETRI/Korea) W3C TPAC meeting sgkang-3

4 Overview of ITU-T Q14/16 q Tasks m Identify the use cases and requirements m Define functional architectures and its components to support use cases and requirements for DS systems and services m Define DS terminal profiles based on capabilities m Define a framework and protocols to provide content delivery function and audience measurement function for DS services m Define interface specification among functional components of digital signage systems m Define procedures and methods to interact between DS systems and smart devices such as smart phone and tablet PC m Define metadata and media formats of DS contents W3C TPAC meeting sgkang-4

5 q Tasks (Cont.) Overview of ITU-T Q14/16 m Define data formats for communications among terminals/devices in DS services m Define control functions for synchronous/asynchronous presentation of multiple displays/terminals m Define a framework and procedures to provide public service including emergency warning, based on DS systems m Modify and/or extend existing specifications under the ITU-T SG 16 responsibility to enable interoperable DS systems m Collaboration and harmonization with other SBs, forums and consortia to develop Rec. to support DS service W3C TPAC meeting sgkang-5

6 What is Digital Signage in ITU-T? q Definition of Digital Signage in ITU-T SG16 m Defined in ITU-T H.780 (Approved: June 2012) n H.780, Digital signage: Service requirements and IPTVbased architecture m A system that sends information, advertising and other messages to electronic devices (e.g., displays, speakers) in accordance with n 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 W3C TPAC meeting sgkang-6
