Abstract

For a multimedia ring network (A) interconnecting a plurality of units (B), for example built into a vehicle, to be adapted automatically to expansions or reductions with respect to the unite (B), there is a unit serving as the man/machine interface (C), which is built up from an application plane (A⁴), an interface (E), an access plane (F), a data plane (G), a transmitting and receiving unit (H), a function catalog (I) and a program generator (J). Commands input by a user into the application plane (D) are converted to data telegrams in the data plane (E) and fed into the network (A) by the transmitting and receiving unit (H). The addressed units (B) transmit reply telegrams back to the man/machine interface (C), where they are visually displayed in the application plane (D) for the user. The program generator generates the programs belonging to the functions of the network described in the function catalog (I) and transmits them to the interface (E), to the access plane (F) or to the data plane (G).

Claims

1. Method for controlling a plurality of units (B) interconnected in a ring network (A), having a unit serving as the man/machine interface (C), having an application plane (D) for the input of commands by a user and for the display of information received from the network (A), having an interface (E) that connects the application plane (D) to an access plane (F) in which the commands input by the user into the application plane (D) are converted and transmitted to a data plane (G) in which data telegrams are generated and which forwards information received from the network (A) to the application plane (D) for display, having a transmitting and receiving plane (H) that feeds the data telegrams generated by the data plane (G) into the network (A) and forwards data telegrams received from the network (A) to the data plane (G), having a function catalog (I) in which the functions of the network (A) are described, and having a program generator (J) that generates the programs for the various functions and transmits them to the interface (E), to the access plane (F), or to the data plane (G).

3. Method according to claim 1 or network according to claim 2,

characterized in that, upon expansion or reduction of the units (B) of the network (A), a link is effected or exists between the function catalog (I) and the program generator (J) on the one hand and the interface (E), the access plane (F), or the data plane (G) on the other hand.

4. Method according to claim 1 or network according to claim 2,

characterized in that integration of the function catalog (I) and the program generator (J) into the man/machine interface (C) is effected or exists.

5. Method or network according to claim 4,

characterized in that description of the applications of the application plane (D) in the function catalog (I) is effected or exists.

6. Method according to one of claims 1 to 5,

characterized in that provision for a multimedia network is made or exists for the network.

7. Method or network according to claim 6,

characterized in that incorporation of the multimedia network (A) into a vehicle is effected or exists.

8. Method or network according to one of claims 1 to 7,

characterized in that interconnection of the units (B, C) of the network (A) via an optical bus is effected or exists.

9. Method or network according to claim 7 or 8,

characterized in that provision for at least one radio receiver in the network (A) is made or exists.

10. Method or network according to one of claims 1 to 9,

characterized in that description of the functions stored in the function catalog (I) in XML format, ASCII format, or other format is effected or exists.

11. Method or network according to claim 9 or 10,

characterized in that a command for the storage of the name of a selectable station or program is input or can be input into the application plane (D) by the user, that the input command is transmitted or can be forwarded via the interface (E) to the access plane (F), where the command is converted or can be converted for the data plane (G), that a data telegram associated with the command is generated or can be generated in the data plane (G), which data telegram is fed or can be fed into the network (A) by the transmitting and receiving unit (H), that the data telegram is received or can be received by the radio receiver, that the radio receiver, pursuant to the command, feeds the name of the selected station or

program into the network (A) as a reply telegram or that the name of the selected station or program can be fed by the radio receiver, pursuant to the command, into the network (A) as a reply telegram, that the transmitting and receiving unit (H) receives the reply telegram and forwards it to the data plane (G), which forwards it to the application plane (D), where the name of the selected station or program is displayed, or that the reply telegram can be received by the transmitting and receiving unit (H) and can be forwarded to the data plane (G), whence it can be forwarded to the application plane (D), where the name of the selected station or program can be displayed.

12. Method or network according to claim 9, 10 or 11,

characterized in that description of the tuner search function of the radio receiver is effected or exists as a function in the function catalog (I).

2. Ring network (A) interconnecting a plurality of units (B), having a unit provided as the man/machine interface (C), having an application plane (D) for the input of commands by a user and for the display of information received from the network (A), having an interface (E) by which the application plane (D) is connected to an access plane (F) in which the commands input by the user into the application plane (D) can be converted and forwarded to a data plane (G) in which data telegrams can be generated and by which information received from the network (A) can be forwarded to the application plane (A²) for display, having a transmitting and receiving plane (A³) by which the data telegrams generated by the data plane (G) can be fed into the network (A) and data telegrams received from the network (A) can be forwarded to the data plane (G), having a function catalog (I) in which the functions of the network (A) are described, and having a program generator (J) for generating the programs for the various functions for the interface (E), the access plane (F), or the data plane (G).
