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)

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
