If we remove connections marked by " * " signs, we obtain a "traditional” scenario when bundles are delivered to the gateway via Internet and interactive TV applications are delivered to the iDTV receiver via broadcast stream. If we add "*" connections, we obtain new interactions so that their combinations may carry new features.
  • Example features include: (a) delivery of HN bundles via broadcast stream; (b) management of Home Network via Internet; (c) download of some iTV applications via broadcast stream; and (d) use of a return channel for implementation of real interactivity.

  • downloading of iTV applications and HN applications to the iDTV receiver and the HN gateway may be implemented both via broadcast stream and via Internet.
  • this scenario includes both full interactivity and flexibility for possible new combinations of technical solutions.
  • a drawback is that not all consumers have Internet access, which is why it is reasonable to broadcast a mixture of applications that need a return channel and that do not need a return channel (like in scenario 1). Still, it may also be reasonable to produce applications that are compatible with both scenarios 1 and 2, i.e. the applications that implement all functionality in scenario 2, but may work without a return channel with restricted functionality.
  • a third scenario, Scenario 3 is an interactive broadcast model with a direct return channel to the broadcaster.
  • a return channel may be connected directly to the broadcaster (via a physical return channel -like terrestrial DVB-RCT channel as well as satellite DVB-RCS or cable DVB-RCC or DOCSIS, etc.).
  • Scenario 3 offers potential advantages and disadvantages. For example, an advantage of Scenario 3 is full interactivity like in scenario 2, without need of WAN (internet) connection. However, a drawback of Scenario 3 is that the physical implementation of the return channel is not simple for terrestrial and satellite networks. Yet, implementation of the physical return channel is quite convenient for cable networks. [0059] Turning now to Figure 13, another scenario, Scenario 4, relates to an Interactive broadcast model with connection to a Mobile Communications network.
  • the return channel is connected to the broadcast via the Mobile Communications Network.
  • IP addressing can be used both in mobile networks with switching of packets and in mobile networks with switching of channels (like in fixed dial-up access).
  • This scenario may be used for portable reception where a local network similar to home network is available (e.g. in cars and other vehicles, etc.).
  • This scenario also allows use of remote mobile communication devices that can allow consumers to configure home networks via broadcast gateway when out of the home.
  • Some examples of implemented prototypes are now described. One prototype delivers bundles to the OSGi gateway from the broadcast stream via broadcast carousel and an iDTV receiver. Another prototype accomplishes remote administration of the OSGi gateway from the screen of the DTV receiver.

  • a Bundle may be separated into several messages depending on its size.
  • the Bundle body can be Base64 encoded.
