1. A multimedia device comprising:
a storage device containing a device map that maps, to each of a plurality of devices coupled to the multimedia device, an identification of an attribute indicated in identification data received from the device, wherein the plurality of devices includes an intermediate device coupled to the multimedia device via a first multimedia cable, and a sink media device coupled to the intermediate device via a second multimedia cable;
a multimedia port configured to receive identification data from at least one of the plurality of devices;
an attribute identifier configured to identify attributes in the received identification data;
a device correlator configured to associate the identified attributes with one or more of the plurality of devices using the device map; and
a power state determiner configured to determine a power state of the plurality of devices based on the association of the identified attributes using the device map, the determined power state for each device indicating whether the device is powered on or powered off.
