Definitions

  • the invention relates to an arrangement within a network system, whereby connection of new units to the network is facilitated so as to allow it to be performed by a layman.
  • the network system according to the invention is also designed such that a guaranteed network environment is obtained, whereby a service provider is provided with knowledge about the network environment into which an associated service module is fitted.
  • the TV services will be digital, with improved image quality and with a possibility for inter-activity, of searching for special programs, possibility of composing your own channel offering, etc.
  • the broadband system will enter our homes in the form of a wall outlet con-
  • nector In order to be connected, various types of hardware, service modules, are required, depending on what or which service(s) you want to utilise.
  • the Internet connection requires a PC with a connection module; the TV services require a Set Top Box (STB), which will probably be integrated directly into the TV sets of the future, etc.
  • STB Set Top Box
  • Many of these services will be developed successively, in time with the extension of the broadband network, and the users will probably start with one or a few services, and then buy more successively.
  • All the services will have to be connected to the incoming broadband connector, i.e. in time many services/appliances will be connected to this outlet.
  • the band- width per household allows simultaneous use of a large number of services, and the households will for example be able to surf on the Internet, have a telephone conversation and to watch TV, at the same time.
  • the technical equipment required today for interconnecting and configuring the service modules is relatively complex and requires more than a normal under- standing of how a computer and a network operate. Also with such knowledge, there are pitfalls, due to the technical compatibility between the components of the system not always being perfect.
  • the object of the present invention is to solve the problems associated with new connections to, and extension of, broadband services. At enterprises, authorities etc. there is usually somebody responsible for IT who can handle these procedures, but when users are to begin building up their own networks at home, it would be desirable to simplify the procedure. For the consumer it would be advantageous if connection to the broadband network could be realised like a modular system; easy to install and extend, and simple to use. Today, there are a number of problems associated with network systems, such as the Ethernet, which will become more evident when large portions of the population are to be connected to the broadband network.
  • the average person cannot build networks, which would be necessary in order to get the services without calling in an external installation engineer every time a new service is to be provided.

  • environment is meant e.g.:
  • Every service i.e. the service module that has to be arranged in the home LAN, requires a power supply, and you would want to avoid a separate power supply unit for each service. Furthermore, it ought to be possible to maintain the func- tionality of a service module and the upstream link during a power breakdown, without substantial extra costs.
  • the broadband suppliers must be able to approve of certain products, and to guarantee that a service is only utilising approved products, and that the upward link only comprises approved products. This constitutes a requirement in order for the supplier to be able to offer quality guarantees to his subscribers.
