  1. International Telecommunication Union ITU-R Activities in Multimedia Broadcasting Gérald Chouinard (Vice-chair ITU-R WP 6M) (email: gerald.chouinard@crc.ca)

  2. ITU-R Study Groups • SG1- Spectrum Management • SG3- Radiowave propagation • SG4- Fixed Satellite Service • SG6- Broadcasting Services • SG7- Science Services • SG8- Mobile, Radio Determination (Terrestrial and Satellite) • SG9- Fixed Services • SG6- Broadcasting Services

  3. Study Group 6: Broadcasting • WP6P - Content production / postproduction • WP6R – Recording for production, archival and play-out • WP6A – Program assembling and formatting • WP6M – Interactivity and multimedia • WP6E – Terrestrial delivery • WP6S – Satellite delivery • WP6M – Interactivity and multimedia

  4. WP6M – Interactivity and multimedia • Requirements for interactive radiocommunication broadcast services and systems • Approaches and requirements in multimedia production, coding and multiplexing • Interfaces to webcasting including the supporting data services

  5. Key activities of WP 6M • WRC 2005: multimedia spectrum requirements • Identify service features for interactive broadcasting • Identify return link capacity requirement for interactive broadcasting • 7 Questions to be answered from WRC 2000 • definition of Multimedia service • Expected spectrum requirement • Identify spectrum requirement for multimedia(Joint effort with WP 6E, SG 1, SG 8 and SG 9) • Multimedia TV broadcasting (terrestrial/satellite) • Develop worldwide presentation and execution environments for DTV interactive rendition (XML presentation, JAVA execution engine, EPG, local and remote interactivity, content tagging, copy control) • Multimedia Mobile Broadcasting terrestrial/satellite) • DAB and return link by PCS (e.g., GSM/GPRS)

  6. Attributes of Broadcasting • Broadcasting: program streaming • real time QoS is very important • Broadcasting has been “push technology” and advertisement supported services for many decades • Broadcasting has been dealing with multimedia for many decades: sound, video and data • Broadcasting is used to IPR management of content (paying royalties) • Broadcasting: close to content production, applications and rendition on user terminal

  7. 7 Questions from WRC’2000 • What is your understanding of the term "terrestrial wireless interactive multimedia systems" and its scope? • What specific characteristics (operational and technical) are considered to make a system suitable for terrestrial wireless interactive multimedia applications? • What are the various applications and technologies that may fall under terrestrial wireless interactive multimedia systems? • What is the current situation regarding spectrum use by the applications and technologies identified in question 3 above?

  8. 7 Questions from WRC’2000 (cont’d) • What are the sharing scenarios with respect to other uses of the same spectrum? • What are, if any, the regulatory impediments to the development of terrestrial wireless interactive multimedia systems? • What are the possible trends in this area in the next 5-10 years and how will they impact on responses to the above questions?

  9. Thank you!
