Abstract

What are referred to as set top boxes are employed for controlling interactive video services. In order to select and view video films stored in the network, a call set up to the appertaining memory device is automatically controlled from the set top box with the assistance of a standardized signalling method.

Claims

1. A method for connection control for interactive services that include a plurality of control devices, each of which is allocated to a terminal equipment, and a network node serving for through connection of information and to which a plurality of control devices and at least one memory device is connected, and via which information is conducted from the memory device to one of the control devices and vice versa using an existing connection, comprising the steps of:

automatically setting up a first connection from one of the control devices to the memory device using a standardized real time delivery method, said first connection being capable of broadband transmission;

setting up a second connection from said one control device to said memory device, said second connection being capable of narrow band transmission; and

exchanging broadband information over said first connection and exchanging narrow band information over said second connection for a duration of existence of said first and second connections.

2. A method as claimed in claim 1, wherein said narrow band information being exchanged over said second connection in said exchanging step is control information.

3. A method as claimed in claim 1, wherein said broadband information being transmitted over said first connection in said exchanging step is useful information.

4. A method as claimed in claim 1, wherein said first connection is capable of transmitting video on demand data as said broadband information, said broadband information being transmitted after an end of call set up via said first connection;

and said narrow band information being transmitted after an end of call set up over said second connection.

5. A method as claimed in claim 3, further comprising the steps of:

transmitting further useful information which differs from said useful information narrowband via said second connection.

6. A method as claimed in claim 1, wherein said step of exchanging information transmits information according to asynchronous transfer mode principles.

7. A method as claimed in claim 1, further comprising the step of:

indirectly addressing said memory using said control devices for call setup.

8. A method as claimed in claim 1, further comprising the step of:

implementing a time-dependent and volume-dependent charge calculation during a time span of an existence of said at least one connection.

9. A circuit arrangement for connection control for interactive services, comprising:

an intelligent network including;

a plurality of control devices;

a terminal equipment to which each of said plurality of control devices is allocated;

at least one memory device;

a network node operating to provide a through connection of information, said network node being connected to said plurality of control devices and to said at least one memory device, said network node conducting information from said at least one memory device to each of said plurality of control devices and vice versa using an existing connection;

said plurality of control devices and said at least one memory being operable for automatic call setup from one of said control devices.

10. A circuit arrangement according to claim 9, wherein said control devices are integrated into terminal equipment.
