IPTV & Content Delivery in ETSI
Presenter: Chantal Bonardi
ETSI Secretariat Technical Officer

2. Introduction
After TISPAN and MCD closure, EP E2NA and TC NTECH took over the responsibility for the work on Content Distribution Networks (CDN).
ETSI via a specific agreement signed with DVB Project publishes DVB deliverables following approval by JTC Broadcast
The goal of the DVB IPTV deliverables is to specify technologies on the interface between a managed IP network and retail receivers, enabling the end user to buy a DVB-IPTV receiver in any shop, take it home, connect it to a broadband network, choose and consume DVB services available over the IP network. DVB’s interactive middleware specifications, DVB-MHP and GEM, also include IPTV profiles.

3. Current activities – E2NA/NTECH
Multi-screen convergence service
Interoperable and exchangeable CA-DRM
Content Distribution Network (CDN)
architecture published
protocol specification: ongoing
CDN-I requirements and architecture published

4. Strategic directions – E2NA/NTECH
CDN migration to Information centric networks

5. Challenges – E2NA/NTECH
The changing business model from traditional broadcast to internet/IPTV based distribution
The income for the content generators to be secured also in the future
Gathering inputs from all parties involved in the value chain

6. Next steps & actions – E2NA/NTECH
Finish the protocols for the CDN
Study the migration of CDN to information centric networks
CDN virtualization (in coop with the ISG NFV)
CDN as a use case for Autonomic Management  (GANA instantiation on the ETSI CDN Architecture)

7. Recent and current activities on IPTV – JTC Broadcast
Recent approval of DVB IPTV scrambler specification (TS )
This document specifies scrambling algorithms for IPTV services using MPEG2 transport streams
Current work on update of DVB IPTV specification (TS )
To provide a new functionality like in-home networking, fast channel change or system renewability messages (SRM)
Current work on update of Carriage and signalling of hybrid Broadcast/Broadband specification (TS )
To implement the necessary changes to align the document with the last version of TS

8. IPTV Next steps & actions – JTC Broadcast
Review of all DVB IPTV standards and revisions where appropriate, for instance to adapt IPTV (currently supporting IPv4 only) to IPv6.
DVB studies on:
MPEG-DASH
HEVC and UHDTV (from ITU-R) support in Broadcast
Companion Screen for GEM platform
CI Plus CAM (broadband and MP4 services, CAM resident applications)
3D TV enhancement through HEVC and UHDTV
HTML5 for GEM Platform
