• This presentation is not a new proposal concretely researched.

• Just, an introduction of other SDOs’ status on Interworking between Home Network and IPTV– ITU-T, Open IPTV Forum, DVB Project.

• Then, a new standard item to be researched is briefly introduced.

• I hope to propose officially a new standard item in next October meeting after researching concretely.

Prelude



• The HN has become a preferred environment for many end users to receive multimedia services in the home.

• Thus, IPTV services are likely to be delivered using home networking technology.

• In order to provide IPTV users with good user experience and to bring down the costs, IPTV devices need to interact seamlessly with the HN and with each other on the HN.

• For that purpose, a standardized HN architecture and technology supporting IPTV services might be essential.

entities

– HGI(Home Gateway Initiative) based approach

• Objective and Scope– HNs and IPTV-related entities are defined, and interfaces

between these entities are identified.

ITU-T Q.21/16 (H.622.1)

•Components– Primary Domain (IP-HN-P)

• Deals with IPTV-related IP traffic between the access network and the IPTV terminal device (IPTV TD) including audio and video streams

– Secondary Domain (IP-HN-S and PR-HN-S)• IP secondary domain(IP-HN-S) based on IP protocols

– Ex) IEC 62481 (DLNA) Application Area

• Non-IP secondary domain(PR-HN-S) based on non-IP protocols

– Ex) IEEE 1394



ITU-T Q.21/16 (H.622.1)

•Components– IPTV terminal device (IPTV TD)

• IPTV set-top box

• DMS in case DLNA application area

– Home network terminal device (HN-TD)• Terminal devices that do not directly interact with the

service or network provider may be used by the end-user to use IPTV services on the home network (A traditional TV)

• DMP (Display device) in case DLNA application area



ITU-T Q.21/16 (H.622.1)

•Components– Delivery Network Gateway (DNG)

• A gateway between AN and HN

• Home gateway, Residential gateway and so on are used for the same device

• Providing crucial functions for services on the HN

• Implementing the DNG function (DNGF) that is the set of functions that mediate between the network and service provider domains and the IPTV terminal function (ITF)

– Packet processing and interfaces of the DNG• The packet processing in the sense of QoS and multicast at

the gateway device, which are important aspects for IPTV, is not mentioned in ISO/IEC 15045-1.

• A [ISO/IEC 15045-1] compliant device is required to meet requirements of H.622.1.

– Security consideration • In addition to the protection of devices and information,

designing a [ISO/IEC 15045-1] compliant requires the operational aspects of IPTV services, for example, content protection.

A New Standard Item@ ISO/IEC JTC1 SC25 WG1



Motivation of New Standard Item

• The HN has become a preferred environment for many users to receive multimedia services, such as IPTV, in the home.

• Today or in near future, Telco based or Cable based primary IPTV service providers will put a residential gateway (RG) in the HN to provide various consumer-facing services.– Using the RG, 3rd party or retail IPTV service providers as

well as primary IPTV service providers can implement more advanced and innovative customer service features.

• A new standard item on HES based RG might be required for supporting IPTV services in HN.



New Standard Item

• Local IPTV Service Platform (LISP) on Residential Gateway (Tentative title)– can play a role of a conceptual platform to provide

programming interfaces and functionalities to enable 3rd party or retail IPTV service providers to deliver home network related local IPTV applications and services to end users in the home network.

– can communicate and interwork with primary service delivery platforms to create more value for (Telco based or Cable based originating) primary IPTV service provider as well as end users in the home network.

– can be a “patch on” solution of the residential gateway for HES(ISO/IEC 15045-1), that is, not a “built in” solution.



New Standard Item

• What can be home network based local IPTV applications and services through LISP on RG? – Home Control & Automation Services

– Home Media & Information Services

– Healthcare Services

– Internet Telephony

– Public Interest Services

– Portal Services

– Targeted Content Distribution

What to do for a New Standard Item?

• To define functional requirements for the LISP on RG in the home network environment – Architecture, Security(Authentication), 3rd Party Service

Provider Management, User Information Management, Content Management, Access Control, Accounting, etc.

• To provide interfaces and functionalities to enable 3rd party or retail IPTV service providers to offer home network based local IPTV applications and services though the LISP on RG.



Conclusions

• Today’s presentation has not been a new proposal concretely researched.

• Just, an introduction of other SDOs’ status on Interworking between IPTV and Home Network– ITU-T, Open IPTV Forum, DVB Project.

• A new standard item to be researched has been briefly introduced.



Conclusions

• The new standard item should be a “patch on” solution of the residential gateway for HES(ISO/IEC 15045-1), that is, not a “built in” solution in order to preserve interoperability of the original ISO/IEC 15045-1 specifications.

I hope to propose officially a new standard item in next October meeting after researching concretely.
