Abstract: Embodiments are described herein for providing infrared (IR) coverage in a media system, IR codeset selection, and/or calibration of IR blasters. In one aspect, a triggering event is detected and an action to be performed by a device is determined. It is determined that the device is controllable using IR signals. An IR command signal including instructions to perform the action is transmitted to the device. In another aspect, a codeset is selected. A determination of whether a signature signal associated with a device indicates a state corresponding to a command including an IR code of an IR codeset transmitted to the device is made. If so, the IR codeset is associated with the device. Otherwise, another command including an IR code of another IR codeset is transmitted. In another aspect, an IR blaster is calibrated based on whether a signature signal indicates a state corresponding to a transmitted command.
