Abstract

A transmission arrangement is provided with a first and a second mobile transmitter for transmitting an information signal to a receiver. The first transmitter is adapted to store subsequent blocks of the information signal in subsequent IP (Internet Protocol) information blocks (IPB) and to transmit the IP information blocks as first information signal via an IP transmission path to the receiver. Furthermore, the first transmitter is adapted to transmit a second information signal derived from the first mentioned information signal in subsequent information blocks as a second transmission signal via a second transmission path to the second transmitter. The second transmitter is adapted to derive an error correction signal from the second transmission signal and to transmit the error correction signal in IP information blocks as a third transmission signal via a third transmission path to the receiver. At least the second mobile transmitter includes a smartphone operating system. Deriving the error correction signal in the second transmitter can be realized by already converting the information signal in the first transmitter into an error correction signal, and the second transmitter merely derives the error correction signal from the second transmission signal.

Claims

1. A transmission arrangement provided with a mobile transmitter, for transmitting an information signal, e.g. an audio information signal, to a receiver, the mobile transmitter being adapted to store subsequent blocks of information of the information signal in subsequent IP (Internet Protocol) information blocks (IPB) and to transmit the IP information blocks as a first transmission signal via a first transmission path to the receiver, wherein the transmission arrangement is further provided with at least a second mobile transmitter, that the first mobile transmitter is further adapted to transmit a second information signal derived from the first mentioned information signal, in subsequent information blocks as a second transmission signal via a second transmission path to at least the second mobile transmitter, that at least the second transmitter is adapted to receive the second transmission signal from the first mobile transmitter, to derive an error correction signal from the second transmission signal and to transmit the error correction signal in IP information blocks as a third transmission signal via a third transmission path to the receiver, the first and third transmission path running via different transmission networks, and, that at least the second mobile transmitter comprises a smartphone operating system.

2. The transmission arrangement as claimed in claim 1, wherein the first mobile transmitter is adapted to transmit the first information signal via the second transmission path to the second mobile transmitter, and that the second mobile transmitter is adapted to receive the first information signal from the second transmission path , to convert the first information signal in the error correction signal and is adapted to store subsequent blocks of the error correction signal in the IP information blocks of the third transmission signal.

3. The transmission arrangement as claimed in claim 1, wherein the first mobile transmitter is adapted to convert the first information signal in the error correction signal and is adapted to store subsequent blocks of the error correction signal in information blocks of the second transmission signal, and to transmit the second information signal via the second transmission path to the second mobile transmitter, and that the second mobile transmitter is adapted to receive the error correction signal from the second transmission path and to convert the second transmission signal into the third transmission signal.

4. The transmission arrangement as claimed in claim 1, wherein the first mobile transmitter comprises a smartphone operating system.

5. The transmission arrangement as claimed in claim 1, wherein the error correction signal equals the first information signal transmitted via the first transmission path.

6. The transmission arrangement as claimed in claim 1, wherein the error correction signal is derived from an XOR processing step carried out on the first information signal.

7. The transmission arrangement as claimed in claim 6, wherein an XOR processing step is carried out successive blocks of the first information signal to derive the error correction signal.

8. The transmission arrangement as claimed in claim 1, wherein the IP information blocks which are transmitted via the first and third transmission paths all include the same first Destination IP address, which first destination IP address is the destination IP address of the receiver, and the information blocks transmitted via the second transmission path include a second destination address, which second destination address is the destination address of the second transmitter.

9. The transmission arrangement as claimed in claim 1, wherein the IP information blocks transmitted via the first transmission path include a first UDP port address, the IP information blocks transmitted via the third transmission path include a second UDP port address, which first and second UDP port addresses equal the port addresses of a first and second port, respectively, of the receiver, the information blocks of the second information signal include a third port address, which third port address is the port address of a port of the second transmitter.

10. The transmission arrangement as claimed in claim 1, wherein the first, second and third transmission paths are mobile phone transmission paths.

11. The transmission arrangement as claimed in claim 1, wherein a transmission path is a mobile phone transmission path and another transmission path is a Bluetooth or a WLAN transmission path.

30. The transmission arrangement as claimed in claim 1, wherein for realizing the second transmission path between the first and second transmitter, an initiation step is carried out using NFC or a QR code.
