5. The system of claim 1 , wherein

the first media device comprises at least one of a television, a radio, an advertising kiosk, and a jumbotron, and

the second media device comprises at least one of a smartphone, a tablet, and a smart watch.

6. A system for providing a second screen experience to an end user, comprising:

a first media device comprising one or more processors and a memory, the one or more processors configured to execute a set of program instructions stored in memory, the set of program instructions configured to cause the one or more processors to:

receive a broadcast signal encoded with primary audio/visual (AV) data and steganographic metadata;

generate a primary audio/visual signal based on the primary AV data via an output device, wherein the output unit includes at least one of a display or speaker, the steganographic metadata extracted from the broadcast signal prior to generating the primary audio/visual signal with the output device of the first media device;

extract a payload, via an extraction module, from the steganographic metadata within the broadcast signal; and

transmit a steganographic metadata signal, via a low energy bluetooth transmitter contained within the first media device, to a second media device, the steganographic metadata signal including the extracted payload, the first media device configured to dynamically change an emitted bluetooth signature of the low energy bluetooth transmitted based on the steganographic metadata encoded within the broadcast signal,

wherein the second media device is configured to generate a supplementary AV signal with an output unit of the second media device, the supplementary output signal based on one or more data identifiers within the extracted payload.

7. The system of claim 6 , wherein the generating a supplementary audio/visual signal with an output unit of the second media device comprises:

generating an audio notification associated with the primary AV signal with one or more speakers of the second media device, and

generating a visual notification associated with the primary AV signal with a display of the second media device.

8. The system of claim 6 , wherein the generating a supplementary audio/visual signal with an output unit of the second media device comprises:

displaying a selectable link associated with the primary AV signal on a display of the second media device, and

displaying an advertisement associated with the primary AV signal on the display of the second media device.

9. The system of claim 6 , wherein the one or more processors of the first media device are configured to:

receive the primary AV signal with one of a microphone or a camera of the first media device, and

extract the payload of the steganographic metadata from the primary AV signal.

10. The system of claim 6 , wherein

the first media device comprises at least one of a television, a radio, an advertising kiosk, and a jumbotron, and

the second media device comprises at least one of a smartphone, a tablet, and a smart watch.

11. A system for providing a second screen experience to an end user, comprising:

a first media device comprising one or more processors and a memory, the one or more processors configured to execute a set of program instructions stored in memory, the set of program instructions configured to cause the one or more processors to:

receive a broadcast signal encoded with primary audio/visual (AV) data and steganographic metadata;

identify one or more content identifier (ID) markers within the steganographic metadata of the broadcast signal;

identify supplementary content associated with the one or more content ID markers within a supplementary content database; and

transmit a steganographic metadata signal, via a low energy bluetooth transmitter contained within the first media device, to a second media device, the steganographic metadata signal encoded with the identified supplementary content the first media device configured to dynamically change an emitted bluetooth signature of the low energy bluetooth transmitted based on the steganographic metadata encoded within the broadcast signal;

wherein the second media device comprises one or more processors and a memory, the one or more processors configured to execute a set of program instructions stored in memory, the set of program instructions configured to cause the one or more processors to:
