Question 5/9 - Functional requirements for a universal integrated receiver or set-top box for the reception of cable television and other services |
|
1 Motivation
Continued studies on universal integrated receiver or set-top box for the reception of
cable television and other services include all aspects of a universal integrated receiver
or set-top box with connectivity to the home network, including service definition, architecture, and specifications.
The future service environment will be both IP and broadcast based. It will be highly interactive,
and standardized technology will be critical in creating a convenient and interoperable solution for the consumer.
Because there are many broadcast and IP services available, a variety of functions will be
required by devices in the home. Due to considerations of consumer cost and convenience, it
is desirable that these functions be integrated into a single device. In order to provide this
wide variety of services in a manner that is acceptable to service providers, consumers, and
content providers, it is important to standardize a number of critical areas. These include
security, conditional access, protection against unauthorized copying, protection against
unauthorized redistribution (“redistribution control”), device provisioning and management,
quality of service, etc.
Furthermore, itis can be foreseen that the
various services within the scope of Study Group 9, that home users will be able to access over
the digital television infrastructure may be based on various service platforms (middle-wares) that support
proprietary applications. An architecture framework
would be necessary to bundle these middle-wares and to
assure cross-platform1 and multi-platform2 operation operations
among them. It would be very convenient to users if the
integrated receivers or set-top boxes would be designed to
exchange middleware dynamically and
to navigate among applications that users can access, or at least among the most widely employed ones.
The future service environment will be both IP and broadcast based. It will be highly interactive,
and standardized technology will be critical in creating a convenient and interoperable solution for the consumer.
2 Question
- What architecture will be required for the next generation set top box (STB)?
- How will broadcast and IP based service reception, via connection to the access network, be integrated into the next generation STB?
- What technologies will be required to accommodate service delivery over the home network?
- What security, conditional access, protection against unauthorized copying or redistribution is required for the next generation set top box?
- What provisioning and management tools will be required for the next generation STB?
- What type of quality of service will be required for the next generation STB?
- What protocols will be required to enable the next generation STB to interoperate with other devices in the home, including both IP and non-IP devices?
- What technologies will be required to present services to consumers in the next generation STB?
- What types of content management capabilities will be required for the next generation STB?
- What provisions can be made in order that the integrated receiver or set-top box may contain
a facility to exchange middle-ware dynamically and to navigate withinan
an application and among
applications. This would allow the receiver/set-top box to properly operate with
received services that reside in a variety of platforms and applications, thus
providing maximum operating convenience to the home user.
3 Tasks
Tasks include, but are not limited to the creation of an architecture document
describing interoperation among multiple applications and platforms by means of
converged mechanismsn architecture document by
20062009, and also the creation
of one or more specification documents by 2007 2012.
An up-to-date status of work under this Question is contained in the
SG 9 Work Programme.
