3. Highlights from Presentation 1 “MPPA Views on Secure Home Networking”
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

4. Highlights from Presentation 2 “Finding A/V Content on the Home Network: UPnP/DHWG”
Overview of Digital Home Working Group (DHWG)
Summary of DHWG Approach:
Deliver design guidelines based on open standards
Provide a common baseline of media formats
Accelerate market acceptance through compliance and verification testing
Review of DHWG Use Case Scenarios:
Digital Home Player (DHP) as User Interaction Endpoint

6. Highlights from Presentation 4 “Advanced Content Distribution Trial 2003 in Japan”
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

7. Overview of issues in the session
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

8. 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
12/1/2018

9. Follow-up actions
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

10. Conclusion
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
