Abstract
This is directed to processing inputs received from an input mechanism to control media playback operations and volume. The input mechanism can include a first button providing inputs by shorting an electrical circuit, and a second button providing inputs by changing the resistance or tone detected or received by a processor. To process inputs, a processor can first detect and process short events from the first button, and subsequently process button events from the second button.
