Abstract
A universal programmable remote is programmed for being used with a specific apparatus. A sequence of test codes is sent to the apparatus until the apparatus responds. The test codes comprise tags that are sent along. The tags fall all within a same narrow frequency band. An STB that is eavesdropping on the transmission is receptive to that band. The STB identifies the last tag and enables a server to identify the complete set of codes for the apparatus based on the tag. Thereupon the set is downloaded and programmed in the remote.
