Abstract

A method for performing in-field discovery, diagnosis and/or repair of a set-top device includes the steps of: determining whether 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; executing a search and rescue (SAR) module on the first set-top device when it is determined that the first set-top device is non-responsive to the head-end; and re-establishing communications between the first set-top device and the head-end by the SAR module executing on the first set-top device.
