Abstract

A mobile communication appliance (10) sets up a connection to a coordination device (20) via a first mobile radio link (12, 21). This is used to register a request for participation in a radio-based video chat. The mobile communication appliance (10) receives a participation confirmation and records a video signal. The latter is transmitted to a video server (30) via a second mobile radio link (13) for storage. Finally, the mobile communication appliance (10) transmits a message to the coordination device (20), with the message containing a reference to the video signal stored on the video server (30). This reference is forwarded to a transmission station (40), from which the video signal is broadcast as a radio signal (45).

Claims

1. A method for radio-based broadcast of a video signal, comprising:

establishing a link from a mobile communication device to a coordination device via a first mobile wireless link;

communicating a participation request from the mobile communication device to the coordination device via the first mobile wireless link;

receiving a confirmation of participation from the coordination device through the mobile communication device via the first mobile wireless link;

detecting the video signal, comprising an image sequence with audio data;

transmitting the video signal over a second mobile wireless link from the mobile communication device to a video server for storage of the video signal on the video server;

transmitting a message from the mobile communication device to the coordination device the message including a reference to the video signal stored on the video server;

forwarding the reference from the coordination device to a transmitting station; and

broadcasting the video signal through a transmitting station as a radio signal.

2. The method according to claim 1, wherein

after the step of communicating a participation request from the coordination device a check is performed to ascertain whether a time window can be reserved for broadcast of the video signal;

the confirmation of participation is positive or negative as a function of the check; and

detection and transmission of the video signal is performed based on the confirmation of participation.

3. The method according to claim 1, wherein the message comprises a text-based short message.

4. The method according to claim 1, wherein the video signal is detected with a camera integrated with the mobile communication device.

5. The method according to claim 1, wherein the transmission of the video signal is performed using packet-oriented transmission.

6. The method according to claim 1, wherein the transmission of the video signals is based on an H.324-based protocol.

7. The method according to claim 1, wherein the transmission of the video signal is performed by a multimedia messaging service.

8. The method according to claim 1, wherein transmission of the video signal begins during acquisition of the video signal.

9. The method according to claim 1, wherein the video signal is broadcast embedded in a partial area of a television image.

10. The method according to claim 1, wherein the video signal is broadcast as a full screen.

11. The method according to claim 1, further comprising displaying the video signal with a display system before the broadcast.

12. A system for radio-based broadcast of a video signal, comprising:

a camera for a acquiring the video signal;

a video server for storing the video signal;

a coordination device for receiving a request for broadcast of the video signal as a radio signal, sending a confirmation for broadcast in the response to the request, receiving a message with a reference to the video signal stored on the video server, and forwarding the reference;

a mobile communication device for transmitting the request and receiving the confirmation via a first mobile wireless link, transmitting the video to the video server via a second mobile wireless link, and transmitting the message with the reference to the stored video signal; and

a transmitting station for receiving the reference from the coordination device and for broadcasting the video signal as a radio signal.

13. The system according to claim 12, wherein the mobile communication device is designed to transmit the message as a test-based short message.

14. The system according to claim 12, wherein the camera is integrated with the mobile communication device.

15. The system according to claim 12, wherein the transmitting station is designed to broadcast the video signal alone or together with other video signals embedded each in one partial area of a television image.

16. The system according to claim 12, wherein the transmitting station is designed to broadcast the video signal as a full screen.

17. The system according to claim 12, further comprising a display system designed to display the video signal before broadcasting.

18. A mobile communication device configured to:

establish a link to a coordination device via a first mobile wireless link;

communicate a participation request to the coordination device via the first mobile wireless link;

receive a confirmation of participation from the coordination device via the first mobile wireless link;

detect a video signal comprising an image sequence with audio data;

transmit the video signal over a second mobile wireless link to a video server for storage of the video signal on the video server; and

transmit a message to the coordination device, the message including a reference to the video signal stored on the video server, wherein the reference is forwarded from the coordination device to a transmitting station for broadcasting the video signal as a radio signal.

19. The mobile communication device of claim 18, wherein the message comprises a text-based short message.

20. The mobile communication device of claim 18, wherein the video signal is detected with a camera integrated with the mobile communication device.
