ATIS IPTV Standards Development via
ATIS IPTV Interoperability Forum (IIF)
Submission Date:
July 1, 2008
Highlight of Current Activities (1)
• Completion or nearing completion of Phase 1 work activities
– Standards related to Quality of Service Metrics for 1) Linear Broadcast
TV and 2) Public Services
– Metadata specifications for 1) Emergency Alert Provisioning and 2)
Electronic Program Guide 3) Consumer Domain Device Configuration
– Remote Management of Devices in the Consumer Domain
– Interoperability for Secure Download and Messaging

2
Highlight of Current Activities (2)
• Phase 2 work is underway
– Server and Client Side APIs
– Security Robustness Rules
– Distribution of Content in the Subscriber’s Authorized Service Domain
– QoS Metrics for On-Demand Video Content
• Recent partnership agreement signed with MultiService Forum (MSF) for
Global MSF Interoperability event in October 2008
– Will test key IPTV building blocks related to authentication and
initialization at five test sites: Verizon, NCS and UNH-IOL in the USA
and BT/Vodafone in Europe and China Mobile in Asia
• At the time the IIF was created, interoperability verification was included in
the scope of its work
– This verification required major specification work to be completed in
order to define parametric test points for interoperability
– IIF documentation has progressed to the point of interoperability
verification and now allows for this aspect of the IIF work to proceed
3
Strategic Direction (1)
• The ATIS IIF standards development has been defined in three
phases:
– Phase 1: Implementation of a standard TV service experience over
IP networks.
– Phase 2: Transaction-based services, such as VoD (Video on
Demand), IPPV (Impulse Pay-Per-View).
– Phase 3: Interactive TV services, including consumer originated
video, multiplayer games.
• Whenever possible, IIF standards align with the work of other
SDOs, including the ITU-T, DVB, CEA, DSL Forum, and ETSI.
– Continue with SDO and ITU-T coordination and collaboration.
– Established important relationships with all of the leading
organizations working in the IPTV realm to share our end-to-end view
of the standards being developed.
4
Strategic Direction (2)
• ATIS IIF is developing standards within and across all of the
domains.

• Support both the IMS and web services approach to IPTV in the
NGN framework.
– The IIF’s High Level Architecture shall allow for both core IMS and
non-IMS approaches for IPTV in the NGN framework.
– The core IMS and non-IMS approaches shall be able to co-exist on
the same NGN framework.
– The core IMS and non-IMS approaches shall use common
components where possible.
• Timely completion of deliverables to support early deployment of
standardized IPTV.
5
Challenges
• In 2007 IIF agreed to develop and harmonize both IMS and NonIMS (web services) approach to IPTV.
• The IIF approach is based on different signalling and transport
protocols being used to access COMMON data structures.
• IMS and Non-IMS are not tangential approaches to the same
application rather, applications are driven by common data
structures that can be acquired via multiple methods.
6
Next Steps/Actions
• Complete currently defined work program (Phase 1 work, per IIF
Architecture Requirements and Roadmap).
• Creation of Phase 2 work items (Issues) has already begun (VoD,
Fast Channel Change, Hybrid networks etc.).
• Continue IPTV OSS/BSS work program.
• Continue to work cooperatively with external organizations,
especially the ITU-T, on aligning efforts and work products.
• Strategic agreement with the MultiService Forum (MSF) to test IIF
Phase 1 specifications at the Global MSF Interoperability (GMI)
2008 event.

Committee Work Program
• Comprehensive Work Program
– The ATIS IPTV work program is comprehensive, including work
planned or underway in areas such as architecture, multiple access
network technologies, security and digital rights, testing,
interoperability, metadata, operational support systems/business
support systems (OSS/BSS), identity management, quality of service
(QoS), and quality of experience (QoE).
• Aggressive/Robust Program Management
– The ATIS IPTV Interoperability Forum (IIF) has an aggressive
program management approach to driving standards development.
This robust program drives the development of IPTV standards in the
time and manner demanded by the business objectives of the ATIS
member companies and the global marketplace.
11
ATIS’ Market-Driven IPTV Work
Program
• Broad industry representation
– ATIS has representatives from the requisite industry sectors (service
providers, vendors, customer equipment manufacturers, etc.) leading,
supporting, and driving the IPTV work.
• Broad industry liaisons
– ATIS has established important relationships with all of the leading
organizations working in the IPTV realm to share our end-to-end view
of the standards being developed.
12
ATIS Committee Involvement
• IPTV, Primary (End-to-End) Responsibility:
– IPTV Interoperability Forum (IIF)
• IPTV OSS/BSS Work:
– Telecom Management and Operations Committee (TMOC)
– Ordering and Billing Forum (OBF)
– ATIS CIO Council (IPTV Working Group)
• IPTV Identity Management
– Packet Technologies and Systems Committee (PTSC)
13
IIF Mission
 The IIF enables the interoperability, interconnection, and
implementation of IPTV systems/services by developing
ATIS standards and facilitating related technical activities.
The IIF will place an emphasis on North American and ATIS
Member Company needs in coordination with other regional
and international standards development organizations.
14
IIF Scope
1. Coordinate standards activities that relate to IPTV
technologies. This includes providing a liaison function
between the various SDOs and forums that are each working
on important components for multimedia, but may not have
visibility to other aspects of the application.
2. Develop interoperability agreements, technical reports, or
other types of ATIS standards where appropriate.
3. Provide a venue for interoperability activities.
4. Provide a venue for the assessment of IPTV issues in the
context of NGN directions.
15
IIF Committees
IIF Architecture Committee
• The Architecture Committee develops IPTV architecture
requirements and specifications required to enable
deployment of a standardized, interoperable, access
agnostic NGN IPTV service.
IIF IPTV Security Solutions (ISS) Committee
• The IPTV Security Solutions Committee works with other
standards groups involved in content security activities,
with the end goal of selecting a single security method or
establishing a framework where multiple methods can be
utilized for an interoperable standardized security
solution for IPTV services.
16
IIF Committees (cont’d)
IIF Metadata and Transaction Delivery (MTD) Committee
• The Metadata and Transaction Delivery Committee
investigates the IPTV architecture to identify metadata
elements which require standardization including
security, connectivity and transport, and performance
metric metadata required for transport of time sensitive
information. In addition, the Committee shall specify the
encoding format for the metadata.
IIF Quality of Service Metrics (QoSM) Committee
• The Quality of Service Metrics Committee develops metrics,
models, tools, and techniques for measurement for quality of
service and quality of experience for IPTV services.
17
IIF Committees (cont’d)
IIF Testing and Interoperability (T&I) Committee
• The Testing and Interoperability Committee addresses IPTV
interoperability issues identified through analysis, planning,
trials, deployments, and operations, and provides
recommended courses of actions. In addition, necessary
test scripting and test planning for post-standardsdevelopment testing-events are developed to mitigate field
deployment issues.
