The ETSI Technical Body TC TISPAN focuses on enhancing IPTV solutions for both fixed-line operators and user mobility across diverse access technologies. Collaborating with DVB, it aims to standardize technologies that connect managed IP networks with retail receivers. Key initiatives include developing content distribution network specifications, addressing IPTV security, and improving service features. As media consumption evolves, TISPAN and TC MCD are working to ensure interoperability and resilience in IPTV services while exploring strategic directions and addressing industry challenges.

Transcription de la présentation

  1. IPTV in ETSI Presenter: Richard Brennan, Vice-chair TC TISPAN Global Standards Collaboration (GSC) GSC-15

  2. Introduction (1) • TC TISPAN works as a traditional ETSI Technical Body.The goal of TISPAN for IPTV is to provide solutions for fixed lines operators, and for mobility of the user and switch to different access technologies. • 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. Introduction (2) • TC-Media Content Distribution (MCD) is the ETSI technical body in charge of guiding and coordinating standardization work aiming the successful overall development of multimedia systems (television and communication) responding to the present and future market requests on media content distribution. • TC MCD is addressing the domain of interoperability of content distribution and the related services in a converged environment supporting IPTV, Mobile TV and broadcast TV.

  4. Current Activities - TC TISPAN • Content Distribution Network architecture specification • IPTV Security study • Evolution of protocols for R3 IPTV features to allow attractive, differentiated IPTV services (e.g. Bookmarks, PPV, Playlist features...)

  5. Current Activities - JTC Broadcast • ETSI TS 102 034: “DVB; Transport of MPEG‑2 TS Based DVB Servicesover IP Based Networks” revised as commercial requirements evolved. New Functionalities in rev. 1.4.1: • Support for Remote Management and Firmware Update Services (RMS-FUS) ETSI TS 102 824 • Support for Content Download Services for user (pull download) or service provider (push download) initiated download of content items to the Home Network End Device (HNED) • Optional retransmission mechanism to provide for protection against packet loss of RTP streams • Regionalization metadata to enable a Home Network End Device to acquire the region in which it is located (CellID assignment) • ETSI TS 102 905: “Technical Specification for DVB Services in the Home Network Phase 1”

  6. Current Activities - TC MCD • The following activities are on-going: • Standardization work outside ETSI • 3D gaming graphics delivery • Content Delivery Network • EPG distribution • Subtitles distribution

  7. Strategic Directions - TISPAN • Evolve IPTV services. • Offer solutions for IPTV and CDN for NGN as network choice. • Improve Resilience, Scalability and Flexibility of IPTV solutions.

  9. Strategic Directions - MCD • Complement other ETSI activities in the field also from the Content Providers prospective. • TC MCD is in contact with other relevant bodies within and outside ETSI, and try to foster a modular and harmonized standardization environment aiming to coordinate efforts and prevent duplication of activities.    

  10. Challenges - TISPAN • Is targeted advertising for Broadcast services feasible? • IPTV roaming/Interconnection? Remote Access IPTV quality sufficient? • How to integrate IPTV "Over-the-top" services? Successful business model? • Flexible and Secure IPTV DRM.

  11. Challenges - JTC Broadcast • Industry shift from pure broadcast and pure IPTV systems to hybrid (broadcast/broadband/Internet) systems and pure Internet TV distribution • DVB-IPTV solution developed for managed IP networks • No commercial deployment fully compliant to DVB-IPTV • But many building blocks deployed and referenced by other SDOs e.g.: • SD&S and BCG referenced by ETSI-TISPAN, Open IPTV Forum • AL-FEC referenced by ITU-T, ATIS-IIF, ETSI-TISPAN, Open IPTV Forum • NGN dedicated IPTV subsystem reuses all applicable DVB-IPTV technologies

  12. Challenges - MCD • 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 new value chain

  13. Next Steps & Actions - TISPAN • Finalisation of TISPAN Release 3 issues. • Define the protocols of a CDN • Handle urgent challenges impacting business case(s) for IPTV. • Studies around NGN as network choice for IPTV, CDN.

  14. Next Steps & Actions - JTC Broadcast • Functionalities completed or under development for a new revision of ETSI TS 102 034 in 2010/2011: • Fast Channel Change • System Renewability Messages • Revision of published specifications, e.g. DVB-IPTV profiles and guidelines documents • DVB looking at unmanaged IP networks and hybrid (broadcast/broadband/internet) systems which may lead to new ETSI deliverables. • Investigate technology options to deliver DVB type content over the Internet to a large number of CE devices (includes game consoles), PCs or mobile devices • Application and services delivered over a hybrid infrastructure. DVB has started to look into a new version of the MHP/GEM for hybrid.

  15. Next Steps & Actions - MCD • Going from the start up to full steam mode. • Involve more participation from non traditional standard contributors. • MCD’s ambition is to consolidate its positioning as an active forum where all players in the value chain can come and contribute.
