Interested in “true” interoperability, including content
protection mechanisms that secure content usage rights
A home network must securely manage content usage
rights
Compares and contrasts traditional content protection
mechanisms with the “Broadband Enabled World”
Summarizes threats, requirements, and usage rights
necessary for securing content on the home network
Reviews several forums engaged in establishing content
protection systems

Overview of a Ministry of Public Management, Home Affairs, Post
and Telecommunications (MPHPT) sponsored trial involving 10 Major
Japanese broadcasters, carriers, and vendors
Trial was made up of three component projects:
 Clearance system of copyrights
 Broadband content distribution system
 Content distribution in the educational field
Trial demonstrated:
 HDTV content multi-transmission via both 64-QAM and IP
 Various user navigation models using various forms of metadata
 Secured content distribution by RMPI

Overview of issues in the session



5/31/2016
Interoperability a several levels is very important
 Content interoperability for content protection
 Interoperability of consumer devices through open and
fair standards
Content protection is very important
 Through active measures that insure content usage
rights are respected
 Through passive measures, such as watermarking
Demonstration of content distribution over QAM or IP
through MPHPT trial

Recommendations

Open standards are clearly necessary to support interoperability and
broader adoption of home networks
ITU-T Recommendations J.190, J.191, and J.192 provide the basis for
a secure, managed home network which is necessary to provide
advanced multimedia services throughout the home
Digital Home Working Group (DHWG) is developing guidelines for
interoperability
These recommendations do not yet address the issues of content
protection
A requirements document for Digital Rights Management (J.DRM) has
been submitted to ITU and approved for progression
Continued work on J.DRM in ITU SG9 is recommended

Follow-up actions



5/31/2016
Establish a liaison relationship between ITU SG-9 and
both the Universal Plug-and-Play (UPnP) Forum and the
Digital Home Working Group (DHWG)
Adoption of J.DRM requirements document by ITU SG-9
Further work in developing specifications based on the
J.DRM requirements

The ITU-T Workshop on Home Networking and Home Services has
been very productive in highlighting key issues for standardization
The exchange of ideas and perspectives from around the globe has
expanded our scope of thinking
There are a large number of areas of standardization that can be
pursued
The Home Networking and Home Services Workshop has clearly met
its objectives:
 Promotion of developing international standardization on Home
Network
 Study possible and effective scenarios toward the integration of IP,
broadcasting and image information services
 Identify future requirements for international standardization and
collaboration with ITU-T/R Study Groups, SDOs, Forums, etc.
My sincere thanks to our hosts and workshop organizers
