Method and device for recognition and arbitration of an input connection
First Claim
1. A TIP, RING, RING, SLEEVE (TRRS) device for dynamic pin allocation of a TRRS controller in response to an audio device connection, comprising:
- a processing unit communicatively coupled to one or more multimedia connections consisting of TRRS headphone audio, universal serial bus (USB), and a proprietary serial protocol; and
an audio jack communicatively coupled to the processing unit over a TRRS line connection consisting of a Tip line, a Ring 1 line, a Ring 2 line, and a Sleeve Line,wherein the processing unit, upon insertion of an audio device by way of an audio connector inserted into the audio jack, automatically recognizes and arbitrates a dynamic pin allocation on the audio jack to accommodate a multimedia type of the audio device thereto inserted, wherein the processing unit detects an audio configuration of the audio device by way of current and load sensing through the audio jack, wherein the processing unit, upon detection of a connector type of the audio connector of the audio device, independently assigns data lines to or from the audio device to pins utilized for the TRRS line connection in accordance with the connector type detected, and wherein the processing unit, upon detection of a microphone signal, reconfigures the pins based on the microphone signal.

Abstract
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.

10. A TIP, RING, RING, SLEEVE (TRRS) controller for managing and delegating dynamic pin allocation of an audio jack in response to an audio device connection, comprising:
-
a processing unit communicatively coupled to one or more multimedia connections, consisting of TRRS headphone audio, USB and a proprietary serial protocol; and wherein the TRRS controller is communicatively coupled to the audio jack over a line connection consisting of a Tip line, a Ring 1 line, a Ring 2 line, and a Sleeve Line, wherein the processing unit arbitrates and negotiates multimedia connections and converts between multimedia types and formats to provide for universal connectivity, and wherein the processing unit detects an audio configuration of an audio device by way of current and load sensing through the audio jack, wherein the processing unit, upon detection of a connector type of an audio connector of the audio device, independently assigns data lines to or from the audio device to pins utilized for the line connection in accordance with the connector type detected, and wherein the processing unit, upon detection of a microphone signal, reconfigures the pins based on the microphone signal. - View Dependent Claims (11)
