1 Open multi-provider delivery of TV services over IP networks

2 Introduction Content of the presentation 8 Introduction to DVB-IPI and its application to Medianet open system vision 8 Challenges in realistic application of this concept 8 Outcomes and conclusion 2

3 What is DVB? Digital Video Broadcasting project 8 Industry led consortium of over 260 broadcasters, manufacturers, network operators, software developer, regulatory bodies 8 Over 35 countries 8 Objectives: - Design global standards for delivery of digital television and data services. 8 Organization Steering Board Theme(s) Commercial module Requirements Technical module Workshops Proposal DVB votes Publish Blue Book (via ETSI) 3

4 DVB IPI : basics Home Network Reference Model Prime target of DVB IPI Phase 1 spec (high volume low cost equipement Dos not cover home networking 4

5 DVB IPI : multiservice DVB IPI Phase 1 Scenario 2 Two DNGs & Two Home Networks Service Provider A Service Provider B DNG A HNED A DNG B Multiple Home Networks One DNG per Home Network Home Networks not connected Single/Multiple Service providers Single/Multiple HNEDs per DNG HNED B 2 5

6 DVB-IPI : Operation DVB IPI 8 Main steps: STB network connection Network access initialization STB network configuration SD Entry Points discovery IP configuration + Service location (domain name) Base : DHCP Domain name resolution for discovering the DVB services entries. Base : DNS SP discovery DVB information collection Service provider(s) discovery information collection. Base : HTTP (pull) or IGMP (push) Service(s) offering Base : HTTP 6

7 Broadcast IP-TV Open multi-provider Architecture Encoder,splitter IP access Service 1 (TVBlue) : 4 TV channels DVB-IP Set-top box IP Home Network Service 2 (GoodTV): 3 TV channels SD&S service? SD&S server name Available services? TVblue (list channels), GoodTV (list channels) Join TVblue, channel2@ip Video@IP DNS Service discovery (SD&S) 7

8 IP television today Users get a full bundle : - ADSL modem, IP STB, DSL Access, Internet service, IP television - Television bouquet, Telco, hardware are unique vertical packages The system is engineered and developped by each Telco, with diverging options - HTML and browser based : close to IT model - Multicast DVB-SI based : close to broadcast TV model - Mixed models High investment and low flexibility - Long commitments needed by all stake holders 8

9 We had a dream.. Step 1 : Purchase a retail STB - video quality, ergonomy, brand Step 2 : Subscribe to broadband - speed, QOS, web hosting, mail boxes Step 3 : List and select TV services - Typology, VOD, pricing model Step 5 : Zap - automatic complete accurate channel list Step 6 : Discover and select extra services - EPG, content push, videophone 9

10 DVB IPI Advantages Solutions for Audio/Video service offerings and terminals (End-to-end solutions) Model for manufacturers, network providers, service providers, content provider & existing broadcasters. Interactivity is MHP, independent of the transport layer (DVB-S, DVB-T, DVB-H, DVB-IP, ) 8 For example, in Medianet we have added a MHP-PVR Common metadata, service descriptors and service discovery mechanisms: produce once but distribute several times 10

11 DVB IPI and Medianet 8 Transport of MPEG services over IP networks Content access + Content description (via EPG); MHP-PVR implementation in progress. 8 Structuring interoperability between STB, TELCO & ISP and TV service provider. 8 Ability to handle multiple service providers over the same access networks 8 Creating a stable core to for IP television subsystems STB, access network, services information base, electronic guides Mutualisation of core development and validation => reduced system cost 8 Better acceptance from end user and industry Harmonized interfaces, processes Mutual commitments of stake holders less driven by technical constraints Service bundling 11

12 Stairway to open system Open system Open basic services Services Adapted cores Advanced offer Advanced offer Full custom Customized equipment Basic offer Basic offer Full Specific Standard cores Basic retail STB Advanced retail STB 12

13 What we ve learn? DVB-IPI can replace many proprietary variants of service discovery and content distribution. For traditional broadcasters (DVB-S or C) DVB-IPI is easy to deploy (Full SI TS supported, same source of content). DVB-IPI is convenient to provide interactive and multimedia services (MHP middleware can work with DVB-IPI). Guidelines for DVB-IP Phase 1 Handbook (IPI 2038): This document is targeted to be used by anyone wishing to understand or implement the DVB-IP specification. (Approval at next IPI meeting on 29th of November) 13

14 IPTV and HN Home networking soars on broadband explosion 8 DVB actively developping missing standards IPTV and IP HN provides unique possibility to grow the market through: 8 Leverage IPTV experience through IP HN - When you buy additional IP devices, enjoy content in them through your existing networked STB 8 Leverage IP HN experience though IPTV content - When you subscribe to IPTV service, enjoy content on existing IP HN devices everywhere Challenges: 8 Seamless interoperability between IP STB and IP HN devices 8 Horizontal retail business models based on open standards (DVB-IPI, DLNA,, together!) 14

15 Outcomes and perspective Outcomes 8 Medianet open model is possible with DVB-IPI approach 8 This concept is applicable to realistic embedded environment as fused in mass volume deployements 8 DVB-IPI implementation guidelines enhanced with Medianet results Perspectives 8 Keep on feeding Medianet results to DVB-HN and IPI 8 Promote Medianet open model for IP television system 8 Use Medianet approach to address multi-network systems e.g. satellite/ip hybrid 8 Jump to industrial phase: create and deploy IP television systems based on Medianet concepts 15
