Copyright © Digital Video Broadcasting Project DVB Short summary of DVB-internal Workshop on Network and Service Convergence held on June 6th in Frankfurt

Slide 2 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

Slide 3 Sorts of Convergence and their impact seen from the operator Service Convergence -Place-Shifting -Device Shifting -Remote Self Care Service Innovation Infrastructure Cost (IT/Network) Commercial Efficiency Technical Efficiency Marketing Convergence -Single Bill -Single Price -Cross-Service Discounts Convergent Architecture Applicative Broker Engine NGN/IMS architecture Seamless Network Management

Slide 4 Building blocks and related technology choices Metadata (Content/ Service Guide) Information for the user about the availability of services, their content, and options to purchase access. e.g. DVB BCG, DVB IPDC ESG, OMA BCAST SG Service Protection / Content Protection Protection of the service against unauthorized access. 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, DVB- CSA, ISMACryp, OSF, 18C Delivery ProtocolsProtocols for the delivery of real time media (audio-video streams) and non-real time media (files). e.g. MPEG2-TS, direct RTP, HTTP, FLUTE CodecCoding formats for audio and video mainly. e.g. H.264, VC-1, MPEG2, HE-AAC, AC-3 Control ProtocolsProtocols to control service selection/sessions e.g. RTSP, IGMP, SIP, HTTP

Slide 5 Building blocks and related technology choices InteractivityFormats 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 users 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 6 Example: Share common key technologies between the 3 DVB domains

Slide 7 Example: Reuse of DVB building blocks in TISPAN IMS-based architecture* *: There is a similar one for the NGN dedicated approach

Slide 8 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
