Digital broadcasting in areas with poor transmitting power

1 . A method for transmitting programs and/or data, said method comprising the steps of:

transmitting programs and/or data by a broadcast transmitter to a first transmission area having a first reception power and to a second transmission area having a second reception power;

receiving programs and/or data in the first transmission area by a receiving module of a retransmission unit;

converting the programs and/or data by a conversion module of the retransmission unit;

connecting a mobile communication device to an access node of a local wireless network having bidirectional communication in the second transmission area;

retransmitting the programs and/or data in the second transmission area via a communication interface of the retransmission unit to the local wireless network; and

receiving programs and/or data in the second transmission area by the mobile communication device via an interface of the mobile communication device to the local wireless network.

2 . The method according to claim 1 , wherein the programs and/or data are received in the second transmission area by the mobile communication device via the interface of the mobile communication device to the local wireless network and/or via the broadcast interface.

3 . The method according to claim 1 , wherein the mobile communication device is a mobile radio device for a GSM and/or UMTS mobile radio network, which mobile radio device is identified in the mobile radio network by an identification module.

4 . The method according to claim 1 , wherein the programs and/or data are of a type belonging to the group comprising DAB (Digital Audio Broadcast), DVB (Digital Video Broadcast), DVB-H (Digital Video Broadcast-Handheld) and GPS (Global Positioning System) types.

5 . The method according to claim 1 , wherein the mobile communication device transmits control and/or monitoring data at least partially via the local wireless network to a communication module of a broadcast provider.

6 . The method according to claim 1 , wherein the mobile communication device includes a mobile radio network interface used as a fallback interface to the communication module of a broadcast provider.

7 . The method according to claim 1 , wherein the mobile communication device includes an input device for selecting the programs and/or data to be disseminated.

8 . The method according to claim 1 further comprising the steps of:

transmitting a request for transmission of programs and/or data to the retransmission device from the mobile communication device upon entry into the second transmission area, and

retransmitting the requested programs and/or data from the retransmission unit via the local wireless network to the mobile communication device.

9 . A device configured to retransmit programs and/or data, comprising:

a receiving module configured to receive programs and/or data in a first transmission area,

a conversion module configured to convert programs and/or data into a different form, and

an interface configured to retransmit converted programs and/or data over a bidirectional local wireless network in a second transmission area.

10 . The device according to claim 9 , wherein the programs and/or data are of the DAB (Digital Audio Broadcast) and/or DVB (Digital Video Broadcast) and/or DVB-H (Digital Video Broadcast-Handheld) and/or GPS type.

11 . The device according to claim 1 , wherein the local wireless network in the second transmission area is a WLAN 802.11 network and/or a Bluetooth network.

12 . A mobile communication device, comprising:

at least one interface to a local wireless network having bidirectional communication; and

at least one broadcast interface configured to receive programs and/or data that are disseminated unidirectionally by a broadcast transmitter in a first transmission area having a first transmitting power and in a second transmission area having a second transmitting power, wherein

the mobile communication device upon entry into the second transmission area prompts the transmission unit to transmit programs and/or data over the local wireless network, whereby the transmission unit transmits the requested programs and/or data to the mobile communication device via the local wireless network.

13 . A transmission system comprising:

at least one broadcast transmitter, configured to disseminate programs and/or data unidirectionally

at least one retransmission device, which receives programs from the broadcast transmitter in a first transmission area having a first receiving power and retransmits the programs and/or data from a first transmission area having a first receiving power into a second transmission area having a second receiving power, the programs and/or data being retransmitted in the second transmission area to the mobile communication device via a bidirectional local wireless network;

a communication module of the broadcast provider as well as communication modules configured to facilitate communication of the mobile communication device with the communication module of the broadcast provider, wherein

the communication device comprises input elements which transmit input elements selection data, used to select the programs and/or data to be transmitted, to the communication module of the broadcast provider.

14 . The device according to claim 9 , wherein the local wireless network in the second transmission area is a WLAN 802.11 network and/or a Bluetooth network.

15 . The device according to claim 12 , wherein the local wireless network in the second transmission area is a WLAN 802.11 network and/or a Bluetooth network.
