The method enables uninterrupted audio data availability in low reception areas for enhancing the customer experience.

INNTOT TECHNOLOGIES PRIVATE LIMITED (KERALA, IN)

1. An audio data sharing method for radio broadcasting systems that comprises: sharing audio data using vehicle-to-vehicle (V2V) communication (104) and vehicle-to-infrastructure (V2I) unit communication (103) between units in a plurality of vehicles (101) and an infrastructure unit (100) in a low reception area for radio broadcasting, by means of tuner leasing; and forming a framework for message sharing between the units in the plurality of vehicles.

2. The audio data sharing method for radio broadcasting systems, as claimed in claim 1, wherein a structure of a V2V/V2I radio information frame used between the units of the plurality of vehicles and the infrastructure unit consists of a device identification (200), a tuned station (201), a broadcast standard (202), and an extra tuner availability (203).

3. The audio data sharing method for radio broadcasting systems, as claimed in claim 1, wherein when a vehicle of the plurality of vehicles requests to lease out a tuner to play a particular station (603), tuning a vehicle unit of the vehicle or the infrastructure unit to the requested particular station and sending an audio signal having the audio data of the same to the network (604).

4. The audio data sharing method for radio broadcasting systems, as claimed in claim 1, wherein a structure of a V2V/V2I request frame sent between two or more of the units of the plurality of vehicles consists of a receiver device identification (300), a transmitter device identification (301), a request type (302), and station information (303).

5. The audio data sharing method for radio broadcasting systems, as claimed in claim 1, wherein a structure of a V2V/V2I data frame sent between two or more of the units of the plurality of vehicles consists of a transmitter device identification (400), a station information (401), an audio codec (402), the audio data (403), an audio data length (404), and a packet identification (405).

6. The audio data sharing method for radio broadcasting systems, as claimed in claim 1, wherein a structure of a V2VV2I error message sent between two or more of the units of the plurality of vehicles from consists of a transmitter device identification (500), a receiver device identification (501), and an error response (502).

7. The audio data sharing method for radio broadcasting systems, as claimed in claim 1, wherein the V2V and V2I communication in valid signal areas sends information of extra tuners that can be used by other vehicles; at least two vehicles of the plurality of vehicles receiving this information can either request for a current tuned frequency (601) if they were also listening to a same channel or can request to lease out an available tuner to tune to a required channel (608).

8. The audio data sharing method for radio broadcasting systems, as claimed in claim 1, wherein: a. a transmitting vehicle unit of the units of the plurality of vehicles or the infrastructure unit will have a list of how many vehicles receive its data with a vehicle identification of each of the respective receiving vehicles; and b. the transmitting vehicle unit of the units of the plurality of vehicles or infrastructure unit will continue to send the audio data until a last receiving vehicle of the receiving vehicles requests to stop, wherein a stop request will be a request message.

9. The audio data sharing method for radio broadcasting systems, as claimed in claim 3, further comprising receiving a tuner request at the vehicle unit from at least two vehicles of the plurality of vehicles.

10. The audio data sharing method for radio broadcasting systems, as claimed in claim 9, further comprising determining a first requested vehicle of the at least two vehicles that sent the tuner request; assigning the first requested vehicle to the tuner; and sending an error message to the other of the at least two vehicles.

11. The audio data sharing method for radio broadcasting systems, as claimed in claim 7, further comprising sending an audio signal with the audio data of a currently tuned channel from a sending vehicle unit to a network if a request for the currently tuned channel is received at a vehicle of the plurality of vehicles.

12. The audio data sharing method for radio broadcasting systems, as claimed in claim 7, further comprising tuning a first requested vehicle of the plurality of vehicles to a requested station and sending an audio signal with the audio data of the same to a network if the first requested vehicle requests to lease out a tuner to play the requested station.

13. The audio data sharing method for radio broadcasting systems, as claimed in claim 12, further comprising receiving an error message at other vehicles of the plurality of vehicles aside from the first requested vehicle if the unit receives a tuner request from more than one vehicle.
