1. A method, comprising the steps of:
determining that at least a first set-top device is non-responsive to a head-end via a communication channel established between the head-end and the first set-top device, when the first set-top device status is not received in the head-end when expected, wherein the first set-top device is capable of loading and executing an SAR module;
executing a search and rescue (SAR) module on the first set-top device upon determining that the first set-top device is non-responsive to the head-end;
attempting to re-establish communications between the first set-top device and the head-end by the SAR module executing on the first set-top device;
determining that said SAR module executing on the first set-top device is unsuccessful in re-establishing communications between the first set-top device and the head-end;
executing the same SAR module on at least a second set-top device operatively connected with the first set-top device via a local network upon determining that said SAR module executing on the first set-top device is unsuccessful in re-establishing communications between the first set-top device and the head-end, the second set-top device being responsive to the head-end;
collecting, by the SAR module executing on the first set-top device, information relating to an operational status of the first set-top device;
obtaining, by the same SAR module executing on the second set-top device, said information relating to the operational status of the first set-top device; and
sending, through the second set-top device, said information relating to the operational status of the first set-top device to the head-end.
