(modified former Question 10/9)
The in-home physical network platform provides a capable means to deliver
broadband network-based services to household networks. It is in the best
interest of both consumers and service operators to extend this fundamental
advantage of bandwidth to every possible networked device within the home. This
will benefit consumers by providing home network services connected directly to
the broadband content distribution system.
In order to extend the fundamental bandwidth advantage of access network to
all devices connected to the home network, it is necessary for home networks to
provide satisfactory Quality of Service and network management characteristics
so that ultra-wide broadband services (>50 Mbits/s) of the cable-based service
can be maintained.
In addition, home networks are emerging as a popular home distribution system
for entertainment content. Entertainment video delivery is a core business for
service operators, and extending the quality and security associated with
network video service onto the home network is in the interest of service
operators as well as consumers.
An additional important consideration will be bridging IP based home network
services to non-IP consumer electronics devices.
- What performance characteristics should home networks possess in order to
satisfactorily transport data streams associated with specific services as these
streams are passed between access network and the home network and across the
home network to the terminal device?
- What mechanisms should be employed in order to maintain the Quality of Service
(QoS) on data streams associated with specific services as these streams are
passed between the access network and the home network?
- What network management mechanisms should be employed to provision new
network-based advanced services to devices connected to the home network?
- What application management mechanisms should be employed to provision
advanced applications to devices connected to the home network?
- What security mechanisms should be employed to provide protection of the home
- What content protection mechanisms should be employed to provide safeguards
for content stored and distributed on the home network?
- What type of protocol conversions should be used for the purpose of seamlessly
interconnecting IP to non-IP domains?
- What enhancements to existing Recommendations are required to provide energy
savings directly or indirectly in Information and Communication Technologies (ICTs)
or in other industries? What enhancements to developing or new Recommendations
are required to provide such energy savings?
Tasks, to be completed by 2012, include but are not limited to:
- Maintenance of existing recommendations J.190-J.192
- Requirements document for distributing video over home networks, including
consideration of management and provisioning, QoS, content protection, and user
- Requirements document for bridging of IP to non-IP domains
- One or more recommendations to address the issues identified in the
requirements documents listed above
An up-to-date status of work under this Question is contained in the
SG 9 Work Programme.
Cooperation in the study of this Question should be established with Study
Groups 13, 15, and 16 and in particular, strong coordination will be needed with
