Abstract

Various aspects of a method and system for audio data transmission are disclosed herein. The method includes selection of a frequency modulation (FM) band by a first electronic device. The FM band is selected to receive an audio portion of a multimedia content rendered at a display device. The method further includes receipt of a video description portion of the multimedia content, via the selected FM band.

Claims

1. A method for audio data transmission, comprising:

in a first electronic device;

receiving an authentication request from a second electronic device;

transmitting a response to said second electronic device based on said authentication request,

wherein said second electronic device authenticates said first electronic device based on said response;

selecting a frequency modulation (FM) band based on said authentication;

receiving an audio portion and a video description portion of multimedia content, from said second electronic device, via said selected FM band,

wherein said multimedia content is rendered at a display screen of said second electronic device; and

selecting said FM band via a user interface (UI) rendered at said first electronic device.

2. The method according to claim 1, wherein said multimedia content comprises at least said audio portion, a video portion and said video description portion.

3. The method according to claim 1, wherein said audio portion corresponds to a primary audio associated with said multimedia content.

4. The method according to claim 1, wherein said video description portion corresponds to a secondary audio associated with said multimedia content.

5. The method according to claim 4, wherein said video description portion comprises at least one of a first audio that describes a video portion associated with said multimedia content, or a second audio that describes additional information associated with said multimedia content.

6. The method according to claim 5, wherein said additional information comprises at least one of Electronic Program Guide (EPG) information, a trailer, a synopsis, a closed-caption, a sub-title, a title, a rating, genre information, or metadata content associated with said multimedia content.

7. The method according to claim 1,

wherein said audio portion is associated with a first set of audio characteristics, and

wherein said video description portion is associated with a second set of audio characteristics.

8. The method according to claim 7, wherein said first set of audio characteristics and said second set of audio characteristics comprise at least one of a pitch, a tone, an intensity, or harmonic content associated with said audio portion and said video description portion, respectively.

9. The method according to claim 7, further comprising transmitting said audio portion and said video description portion to a third electronic device via a short-range communication network.

10. The method according to claim 9,

wherein said audio portion is played back in synchronization with said video description portion, at said third electronic device, and

wherein said synchronization comprises an adjustment of said first set of audio characteristics with respect to said second set of audio characteristics.

11. The method according to claim 1, further comprising transmitting a notification, to said display screen of said second electronic device, based on a power level of a battery of said first electronic device that is less than a threshold.

12. A method for audio data transmission, comprising:

in a first electronic device;

transmitting an authentication request to a second electronic device;

receiving a response from said second electronic device based on said authentication request;

authenticating said second electronic device based on said response;

transmitting, via a first frequency modulation (FM) band, a first audio portion and a first video description portion of first multimedia content to said second electronic device based on said authentication,

wherein said first multimedia content is rendered at a display device of said first electronic device,

wherein said second electronic device selects said first FM band to receive said first audio portion and said first video description portion of said first multimedia content via said selected first FM band,

wherein said first audio portion is synchronized with said video description portion; and

assigning said selected first FM band, to said first multimedia content, via a user interface (UI) associated with said display device of said first electronic device.

13. The method according to claim 12, further comprising selecting at least one of a language of said first audio portion and said first video description portion based on one of a user preference received via said UI, a geographical location of said display device, or said first electronic device.

14. The method according to claim 12, wherein said first audio portion and said first video description portion are further transmitted to a third electronic device by said second electronic device via a short-range communication network.

15. The method according to claim 14, further comprising disabling at least one speaker associated with said display device of said first electronic device, based on a playback of at least one of said transmitted first audio portion or said first video description portion at said third electronic device.

16. The method according to claim 12, further comprising rendering second multimedia content at said display device of said first electronic device.

17. The method according to claim 16, further comprising transmitting a second audio portion of said second multimedia content via a selected second FM band.

18. The method according to claim 17, further comprising transmitting a second video description portion of said second multimedia content, to said second electronic device, via said selected second FM band.

19. A system for audio data transmission, comprising:

one or more processors in a first electronic device, said one or more processors configured to;

receive, via a transceiver, an authentication request from a second electronic device;

transmit, via said transceiver, a response to said second electronic device based on said authentication request,

wherein said second electronic device authenticates said first electronic device based on said response;

select a frequency modulation (FM) band based on said authentication;

receive an audio portion and a video description portion of multimedia content, from said second electronic device, via said selected FM band,

wherein said multimedia content is rendered at a display screen of said second electronic device; and

select said FM band via a user interface (UI) rendered at said first electronic device.

20. A system for audio data transmission, said system comprising:

one or more processors in a first electronic device, said one or more processors configured to;

transmit, via a transceiver, an authentication request to a second electronic device;

receive, via said transceiver, a response from said second electronic device based on said authentication request;

authenticate said second electronic device based on said response;

transmit, via a frequency modulation (FM) band, an audio portion and a video description portion of multimedia content to said second electronic device based on said authentication,

wherein said multimedia content is rendered at a display screen of said first electronic device, and

wherein said second electronic device selects said FM band to receive said audio portion and said video description portion of said multimedia content via said selected FM band, and

wherein said audio portion is synchronized with said video description portion; and

assign said selected first FM band, to said first multimedia content, via a user interface (UI) associated with said display screen of said first electronic device.
