1 Motivation
The cable television physical platform provides a capable means to deliver broadband network-based services to household networks. It is in the best interest of both consumers and cable 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 cable system.
In order to extend the fundamental bandwidth advantage of cable 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 cable operators, and extending the quality and security associated with cable network video service onto the home network is in the interest of cable operators as well as consumers.
An additional important consideration will be bridging IP based home network services to non-IP consumer electronics devices.
2 Question
- What performance characteristics should home networks possess in order to satisfactorily transport data streams associated with specific cable-based services as these streams are passed between cable 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 cable-based services as these streams are passed between the cable access network and the home network?
- What network management mechanisms should be employed to provision new cable network-based services to devices connected to the home network?
- What security mechanisms should be employed to provide protection of the home network?
- 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?
3 Tasks
Tasks include but are not limited to:
- Maintenance of existing recommendations J.190-J.192 (2006)
- Requirements document for distributing video over home networks, including consideration of management and provisioning, QoS, content protection, and user interface (2006)
- Requirements document for bridging of IP to non-IP domains (2006)
- One or more recommendations to address the issues identified in the requirements documents listed above (2007)
