EBU TECHNICAL - your reference in media technology and innovation DEFINITIONS
EBU TECHNICAL - your reference in media technology and innovation Definitions of Broadband, Broadband TV and IPTV Broadband is a means to distribute a variety of different services including television and VoD via two-way communication networks using IP (internet protocol). Broadband is a high-speed, high-capacity data transmission medium that can carry multiple signals by dividing the total capacity into multiple channels Broadband Television (BTV) is the provision of linear, scheduled television services and Video on Demand (VOD) services over a two-way broadband ifinfrastructure prov iddbided by te lecommun icat ions carr iers to en d consumers, who use the service via a set top box and display, or via an integrated TV receiver. ITU Definition of IPTV: IPTV is defined as multimedia services such as television/video/ audio/text/graphics/data delivered over IP based networks managed to provide the required level of QoS/QoE , security , interactivity and reliability. NOTE: European Commission considers broadband as any network with a capacity higher than 144 kbit/s. (sic!)

EBU TECHNICAL - your reference in media technology and innovation Conclusions of EBU study on Broadband TV in 2005
In 2004/2005 the EBU set up a Project Group BTV (Broadband Television), chaired by Lieven Vermaele. The results are given in the Article published in the EBU Technical Review in April 2005. Main conclusions: BTV has a great market potential. It is able to provide a bundle of media services (e.g. triple play) including IPTV - managed television services over IP based networks Internet TV – unmanaged television services. These TV services consist of Linear TV (channels) Video on Demand (()VoD) Near VoD and Catch-up TV Scheduled VoD (push overnight) Video Podcasting

EBU TECHNICAL - your reference in media technology and innovation IPTV characteristics
Similar service as cable Scalability problem – due to Vertically organised system: IPTV centralised model operator decides on content, Local services – no universal business model, quality level, service user didevices, et c Network bandwidth congestion – Closely managed system competition between different User devices are TV sets or home services networks at home Silo organisation of services Networks are secured, protected IPTV is proprietary – lack of and QoS managed standardisation IPTV offers “broadcast quality” Varying quality – dependence of services – generally high-quality user distance from local pictures including HDTV exchange
EBU TECHNICAL - your reference in media technology and innovation IPTV future trends – Enhanced IPTV
Integrated triple and quadruple play (TV, phone, internet, mobile) Linking of TV with communications: telephony , chat and videoconference system Phone directory on TV screen and click to dial Call logs on TV screen Direct over IP distribution – no MPEG-2 Transport Stream Multi-component IPTV systems Fast Channel Change – faster zapping times Integration of IPTV with open Internet Integration of IPTV devices into the home networks
EBU TECHNICAL - your reference in media technology and innovation Enhanced IPTV – a Follow-Me feature
Same media session – sequentially rendered on different devices Use Case: The user starts a video session on a mobile terminal while on bus Pauses the video while walking home Resumes the video session when at home on the in-home main TV screen The user is charged only once – a unique service session
EBU TECHNICAL - your reference in media technology and innovation Broadcast requirements for delivery in broadband networks
Many broadcasters provide regularly content for IPTV services Live broadcast channels (24/7) Special live events (football matches, rock concerts, Obama’s inauguration) Finished products (films, documentaries, dramas, etc) Broadcast content should always have the same look-and-feel on all platforms and end devices. Broadcaster’ s branding needs to be visible across all platforms. Broadcast content should be repurposed to suit optimally to different displays and pipelines. BdtBroadcast cont ttdtbent needs to be secured dd and prot ttdected. Visibility of broadcasters’ content in programme guides should be appropriate and adapted to media situation in a given market . Broadcasters desire to maintain end-to-end control of signal quality. No filtering of associated services and metadata is allowed.

EBU TECHNICAL - your reference in media technology and innovation Open Internet TV
Many consumers now access television programmes via the Internet Internet offers new , convenient ways to access television content New services, such as the BBC iPlayer, have proved very popular No doubt these services will continue to grow quickly At present, Internet TV services are mostly accessed via PCs This is ultimately limited, as users prefer to watch TV content on a television Therefore, broadcasters would like to integrate Internet TV services into their product portfolio It is about extending the range of content and services available on the tltelevi iision, whil e ma itiiintaining th“lthe “lean bac k” exper ience Both standalone and hybrid broadcast / Internet services are possible Manufacturers will integrate Internet TV in their consumer products – while not turning the television into a PC Broadcasters need to get services to mass market on CE devices –beyond current PCs!
EBU TECHNICAL - your reference in media technology and innovation Internet TV: issues to be addressed
Many incompatible technologies are used to deliver Internet TV services Operating systems: Linux , Windows , Mac Browsers: Opera, IE, Firefox Mozilla Audio/video codecs: Flash, Windows Media, Real, DIVX, H.264 … Delivery mechanisms: HTTP, RTP/RTSP, MMS, various P2P, other proprietary… Different service providers use different technologies On PCs, it is possible to access all these providers by installing many different clients This i s not f easibl e on CE dev ices – they cannot i ncl ud e all possibl e technologies currently used in the internet, a standardised subset is required
Conclusion: We need standards for delivery of internet TV services.
