GSC: Standardization Advancing Global Communications2

IPTV IS HERE!Despite daunting technical, commercial and partnership challenges – -- BT is on target to launch IPTV services to its 8 million U.K. broadband subscribers in the next several months. “The work is done and the trials are under way,” said Clive Selley, CIO of BT Wholesale speaking at Billing & OSS World in Miami. “The potential prize is very large; the challenge is to find new ways of packaging content that is attractive.”

IP-based television will change the way consumers watch TV while opening a new competitive choice for millions, said Lea Ann Champion, senior executive vice president of IP Operations and Services for SBC Communications Inc. (NYSE: SBC) at a U.S. House Energy & Commerce Committee hearing about the future of new technology. "The simple elegance of IP technology is that it allows various broadband applications to communicate and work together to enhance the capabilities of otherwise separate services," said Champion.

T-Online Hungary, a group member of Deutsche Telekom and Hungary’s largest Internet access provider, has selected Alcatel and Microsoft TV as the suppliers for an IPTV pilot project. The trial will have three phases: a technical lab trial, two field trials and a public

market trial.

AT&T Inc. will offer its TV service in 15 to 20 additional markets by year's end, the company said. The telecom will launch the service in Houston next, with additional markets in other regional markets coming online in the third quarter, an AT&T senior vice president said.


Technical Possibilities to “Change the Game” with IPTV

• Video on any IP device: PCs, PDAs, even wireless phones

• Every TV in the house has digital quality video• VoD and DVR serving every TV in the house• Any Video Display device can have multiple

video windows on it• Faster digital channel changes• More flexibility on programming and content


IPTV Definition• Secure and reliable delivery to subscribers of entertainment

video and related services. – Live TV, Video On Demand (VOD) and Interactive TV

(iTV).

• Services are delivered across an access agnostic, packet-switched network that employs the IP protocol to transport the audio, video and control signals.– Not Video over DSL.

• In contrast to video over the public Internet, with IPTV deployments, network security and performance are tightly managed to ensure a superior entertainment experience, resulting in a compelling business environment for content providers, advertisers and customers alike.– Not Video over Public Internet.


ATIS’ IPTV Interoperability Forum (IIF)• March 2005 - IPTV Exploratory Group (IEG) established by the ATIS

Board of Directors to assess the technical and operational opportunities and challenges surrounding deployment of IPTV

• June 2005 – On recommendation of IEG, ATIS Board established the IPTV Interoperability Forum (IIF) as part of ATIS Board’s priority work to:– Bring focus and coordination to standards work needed for IPTV– Resolve issues that may impede adoption of IPTV– Provide venue for interoperability activities– Assess IPTV issues in light of NGN directions

• IIF Mission: Enable the interoperability, interconnection, and implementation of IPTV systems/services by developing ATIS standards and facilitating related technical activities


IIF Focus

Address the Highest IPTV Priority Items for the Industry:1. Overall reference architecture for IPTV2. Industry accepted standardized metrics and

requirements for content security (digital rights management) and the quality of content delivery (Quality of Customer Experience)

3. End-to-End QoS functionality to support multiple services (voice, video and data) on the same network

4. Interoperability standards and testing of components in the video delivery network


ARCH Task Force• IPTV Architecture Requirements document – Now Available

– Define requirements for IPTV architecture, considering:

• Service Descriptions and Capabilities

• Models for Content Sourcing

• Models for billing and settlement arrangements for video services

• Content security

• Network Architecture models (Core, Access, Home) [not just network layer and below]

• Application Architecture models (Service Enablers, App servers, Resources, API and Protocols models, Device functions models)


• IPTV Architecture Requirements document – Now Available(Continuation of previous slide's list of considerations addressed by document)

• IP network supporting infrastructure required to support IPTV. E.g., Domain Name Services (DNS), Network Time Protocol (NTP), network access authentication (RADIUS/LDAP)

• Evolving nature of terminal devices (multi-resolution support)• Models for advertising insertion• Models for viewership reporting to advertisers• Service integration (e.g., caller id on the TV screen)• Content location mechanisms (e.g., Electronic Program

guides, search capabilities, directories)• Content metadata assumptions and requirements (e.g.,

XML/MPEG 7)

ARCH Task Force (cont’d)


• IPTV Architecture Requirements document – Now Available(Continuation of previous slide's list of considerations addressed by document)

• Content transformation services (e.g., changing resolution via MPEG 21 Digital Item Adaptation)

• Interactive TV services (e.g., audience polling, information services15, games)

• OAM of the IPTV infrastructure ( e.g., at the MPEG layer)• IPTV protection/redundancy mechanisms (e.g., at the MPEG

layer)• IPTV interworking between wireline-based distribution networks

and wireless access networks• IPTV Architecture Roadmap – July 2006• Ethernet Packet Loss and its effect on Streaming Video – July 2006• Phase 1 Architecture Reference Model – October 2006

ARCH Task Force (cont’d)


DRM Task Force• Goal: enable wide range of IPTV business models while

keeping IPTV content secure

• IPTV DRM Interoperability Requirements – Now Available– Server side DRM interfaces, layers, and systems

requirements specification– Client side DRM interfaces, layers, systems, and

operational environment requirement specification– Scope: for initial receiving set-top box or digital video

recorder in customer premises (home, business, etc.)

• IPTV DRM Interoperability Specification – March 2007

• IPTV DRM Requirements for Distributing Content in the Subscriber’s Authorized Service Domain – March 2007


• IPTV QoS Metrics Framework – July 2006– Conceptual framework defining QoS metrics for IPTV service delivery

on end-to-end basis. – High level overview of other aspects of QoS definition to be addressed

in future (e.g., Quality of Customer Experience (QoE) model, key metrics and values, measurement and planning tools, measurement methods, timing and synchronization).

• IPTV QoE Model – October 2006– Addresses entirety of customer interface and interaction with a service

(activation and consumption). – Provides tool for service providers in service planning and ensuring

service performance from a user centric view.– May include both subjective and objective metrics.– Will attempt to identify various reference contexts in which such

measurement can be made (e.g., FR/NR).– Customer support, customer response time, billing accuracy, service

ordering lead times not included.

ATIS Proposal for HIS

• ATIS proposed that IPTV be listed as a High Interest Subject (HIS) on the November 8, 2005, GSC Heads of Delegation (HoD) conference call.

• HoDs approved IPTV to be a Joint GTSC/GRSC “Other Topic” for the GSC-11 meetings.

• ATIS has completed, and is in the process of completing, a number of deliverables for IPTV, as IPTV is a rapidly developing technology.

• ATIS proposes that IPTV be elevated to the status of an HIS and that ATIS be the Prime PSO (PPSO) for IPTV.

ATIS - ipdr.org process• ipdr.org collects IPTV requirements for protocol and encoding on billing and

accounting related issues. These requirements are used to enhance the IPDR documents for IPTV.

• ipdr.org provides protocol and encoding requirements to ATIS committees.

• ATIS Committees (TMOC, IIF and OBF), working with ipdr.org, develop IPTV-specific supplement to TMOC requirements documents for all packet-based services and incorporate information into the IIF Reference Architecture.

• ATIS committees define intercompany business applications for IPTV billing/accounting and settlements, ensuring compatibility with TMOC architecture interface protocol and requirement specifications for packet based services.

• ATIS committees obtain international standardization from the ITU where appropriate.
