Abstract

First data is transmitted between a central radio station and at least one transmitter, where the first data is in first data fields of data packets and useful data is in second data fields of the data packets. The first data fields in this context are pre-reserved by the central radio station for the transmission of second data between the transmitter(s) and the receivers.

Claims

1. A method for transmission, comprising:

transmitting data packets between a central radio station and a plurality of receivers via at least one transmitter, the data packets having first data fields and second data fields,

wherein the first data fields contain first data to be communicated between the central radio station and the at least one transmitter,

wherein the first data include operational data assigned to the at least one transmitter to control each transmitter by the central radio station,

wherein the second data fields contain useful data to be communicated between the central radio station and the plurality of receivers, and

wherein, in the at least one transmitter, at least a portion of the first data in the first data fields is overwritten with second data to be communicated from the at least one transmitter to the plurality of receivers.

2. The method for transmission according to claim 1, wherein the useful data are video data and/or audio data of a digital television or radio signal according to the Advanced Television Systems Committee standard.

3. The method for transmission according to claim 1, wherein the first data between the central radio station and the at least one transmitter include operational data assigned to at least one targeted transmitter to control each targeted transmitter by the central radio station.

4. The method for transmission according to claim 1, wherein the first data between the central radio station and the at least one transmitter are operational data, for at least one targeted transmitter, to control each transmitter by the central radio station, the operational data being at least one:

of software-update data, configuration data, data for remote diagnosis, data for remote servicing, data for remote inspection, and control data for remote action.

5. The method for transmission according to claim 1, wherein the first data between the central radio station and the at least one transmitter include operational data of an operational information system between the central radio station and the at least one transmitter.

6. The method for transmission according to claim 1, wherein the second data between the at least one transmitter and the plurality of receivers include data for channel estimation, for synchronization of the receivers with the at least one transmitter and for signal equalization.

7. The method for transmission according to claim 1, wherein the first data are transmitted for each transmitter.

8. The method for transmission according to claim 1, wherein either one of a given partial volume of the first data or an entire volume of the first data is determined respectively for one of the transmitters and displayed by addressing to the respective transmitter.

9. The method for transmission according to claim 1, wherein the first data are transmitted in every data-stream packet between the central radio station and the at least one transmitter.

10. The method for transmission according to claim 1, wherein the first data are transmitted in every n^th data-stream packet between the central radio station and the at least one transmitter.

11. The method for transmission according to claim 1, wherein the first data are transmitted acyclically between the central radio station and the at least one transmitter.

12. A transmission system, comprising:

a central radio station transmission unit, in a central radio station, operable to transmit data packets between the central radio station and a plurality of receivers via at least one transmitter, the data packets having first data fields and second data fields,

wherein the first data fields contain first data to be communicated between the central radio station and the at least one transmitter,

wherein the first data include operational data assigned to the at least one transmitter to control each transmitter by the central radio station,

wherein the second data fields contain useful data to be communicated between the central radio station and the plurality of receivers, and

wherein, in the at least one transmitter, at least a portion of the first data in the first data fields is overwritten with second data to be communicated from the at least one transmitter to the plurality of receivers.

13. The transmission system according to claim 12, wherein the useful data are at least one of video and audio data of a digital television or radio signal according to the Advanced Television Systems Committee standard.

14. The transmission system according to claim 12, wherein the first data between the central radio station and the at least one transmitter include operational data assigned to at least one targeted transmitter to control each targeted transmitter by the central radio station.

15. The transmission system according to claim 12, wherein the first data between the central radio station and the at least one transmitter are operational data for the operation of individual transmitters by the central radio station, the operational data being at least one of:

software-update data, configuration data, data for remote diagnosis, data for remote servicing, data for remote inspection, and control data for remote action.

16. The transmission system according to claim 12, wherein the first data between the central radio station and the at least one transmitter include operational data of an operational information system between the central radio station and the at least one transmitter.

17. The transmission system according to claim 12, wherein the second data between the transmitters and the receivers include data for channel estimation, for synchronization of the receivers with the transmitters and for signal equalization.

18. The transmission system according to claim 12, wherein the first data are transmitted for each transmitter.

19. The transmission system according to claim 12, wherein either one of a given partial volume of the first data or an entire volume of the first data is determined respectively for one of the transmitters and displayed by addressing to the respective transmitter.

20. The transmission system according to claim 12, wherein the first data are transmitted in every data-stream packet between the central radio station and the at least one transmitter.

21. The transmission system according to claim 12, wherein the first data are transmitted in every n^th data-stream packet between the central radio station and the at least one transmitter.

22. The transmission system according to claim 12, wherein the first data are transmitted acyclically between the central radio station and the at least one transmitter.
