Method and device for recognition and arbitration of an input connection
Embodiments herein enable fast and easy interconnectivity among multimedia accessories including mobile devices and other devices. There is only limited space on mobile devices yet there are numerous input connectors. The standard TRRS audio jack is one such input that has and remains common, primarily because it is the accepted standard for audio input; namely, headphones and earpieces for listening purposes. Embodiments herein describe an intelligent switch to that audio jack that permits for additional backward and forward compatibility. It transparently allows a user to insert analog or digital audio devices, such as earphones, without the need to manually reconfigure device settings. The device herein automatically converts between input connector types using the same input convention present on their existing mobile devices. Other embodiments are disclosed.
1. A device comprising:
a connection port configured to accept a Tip, Ring, Ring, Sleeve (TRRS) connector, wherein the connection port is attached to four pins, one pin each configured to electronically connected with the Tip, Ring, Ring, and Sleeve totaling the four pins;
a memory that stores instructions;
a processor configured to execute the instructions to perform operations, comprising:
receiving data from the four pins;
detecting an audio device by using the data from the four pins; and
assigning data lines to or from the audio device through the four pins.
2. The device according to claim 1 , wherein the data lines can be used to charge batteries of the audio device.
3. The device according to claim 1 , wherein the operations further comprise:
separating the data from the four pins into analog signals and digital signals.
4. The device according to claim 3 , wherein the operations further comprise:
converting at least one of the analog signals into a digital signal.
5. The device of claim 1 , wherein the operations further comprise detecting an audio configuration of the audio device by way of current and load sensing through the connection port.
6. The device of claim 1 , wherein the operations further comprise:
recognizing a dynamic pin allocation on an audio jack of the audio device.
7. The device of claim 6 , wherein the operations further comprise:
arbitrating the dynamic pin allocation on the audio jack to accommodate a multimedia type of the audio device.
8. The device of claim 7 , wherein the operations further comprise:
providing connectivity support in response to insertion of the audio device into the device.
9. The device of claim 1 , wherein the operations further comprise:
reconfiguring at least one pin upon detection of a microphone signal.
10. The device of claim 1 , wherein the operations further comprise:
multiplexing a data line on one pin with another data line of another pin of the device.
11. The device of claim 1 , wherein the operations further comprise:
overriding a default TTRS (Tip, Ring, Ring and Sleeve) pin setting to establish a data line.
12. The device of claim 1 , wherein the operations further comprise:
implementing a protocol for communication of data, executing an application, or a combination thereof, when the audio device is connected to the device.
13. The device of claim 1 , wherein the operations further comprise:
providing analog switching in conjunction with digital format conversion.
14. The device of claim 1 , wherein the operations further comprise:
reconfiguring at least one pin upon detecting a microphone signal.
15. The device of claim 1 , wherein the operations further comprise:
negotiating a communication connection with a multimedia service.
16. The device of claim 1 , wherein the operations further comprise:
converting between multimedia types and formats.
17. The device of claim 1 , wherein the operations further comprise:
relaying and buffering digital packets if the audio device is a digital earphone.
18. The device of claim 1 , wherein the operations further comprise:
interleaving or overlaying a detected microphone signal with a speaker signal.
19. The device of claim 1 , further comprising:
injecting a line signal, voltage, or current into the audio jack to assess a response of the audio device.
20. The device of claim 1 , further comprising:
conveying a communication request to automatically download device drivers or plug-ins to support the audio device.
