Short summary of DVB-internal Workshop on
Network and Service Convergence held on
June 6th in Frankfurt

Agenda of DVB Convergence Workshop
Session 1: Convergence seen by key players in the market
Session 2: Convergence seen by the DVB ad-hoc groups active in the
world of IP such as CM-IPTV, TM-CBMS and TM-IPI
Session 3: Integration of closely related DVB technology
Session 4: Options for Convergence in DVB
Session 5: Mapping of common core technologies in both worlds
and presentation of options how DVB could handle
convergence
Session 6: Discussion of options and first conclusion

(IT/Network)
Building blocks and related technology choices
Metadata (Content/ Information for the user about the availability of services, their
Service Guide)
content, and options to purchase access.
e.g. DVB BCG, DVB IPDC ESG, OMA BCAST SG
Service Protection / Protection of the service against unauthorized access. Protection
Content Protection
of the content against unauthorized consumption and distribution
during its whole lifetime (incl. after recording). Achieved by a
combination of Media Encryption and Key Management.
e.g. DVB CPCM, OMA DRM, OMA BCAST SC, Marlin, IPSec, DVBCSA, ISMACryp, OSF, 18C
Delivery Protocols
Protocols for the delivery of real time media (audio-video
streams) and non-real time media (files).
e.g. MPEG2-TS, direct RTP, HTTP, FLUTE
Codec
Coding formats for audio and video mainly.
e.g. H.264, VC-1, MPEG2, HE-AAC, AC-3
Control Protocols
Protocols to control service selection/sessions
e.g. RTSP, IGMP, SIP, HTTP
Slide 4
Building blocks and related technology choices
Interactivity
Formats and instructions that allow the terminal to provide
interactive service components to the user.
e.g. MHP, CE-HTML, DVB-HTML, DIMS, RME, MPEG-LASER
Service
Provisioning
Methods that the end user / terminal can use to request /
purchase access to services.
Terminal
Provisioning
Methods that the service provider can use to configure the end
user’s terminals for reception of the service.
e.g. TR-69, OMA DRM
Convergence to single technology choices in short
and mid-term seems to be problematic
Slide 5
Example: Share common key technologies between the 3 DVB domains

Key topics that have been discussed:
Convergent Architecture for IPTV and IPDC
Convergent Services for IPTV and IPDC
Relation with other Standards Development
Organizations
A second workshop on convergence will be
organized later in the year
