Remarks
Returns the parent input ID.
A TV input may have a parent input if the TV input is actually a logical representation of a device behind the hardware port represented by the parent input. For example, a HDMI CEC logical device, connected to a HDMI port, appears as another TV input. In this case, the parent input of this logical device is the HDMI port.
Applications may group inputs by parent input ID to provide an easier access to inputs sharing the same physical port. In the example of HDMI CEC, logical HDMI CEC devices behind the same HDMI port have the same parent ID, which is the ID representing the port. Thus applications can group the hardware HDMI port and the logical HDMI CEC devices behind it together using this method.
