ABSTRACT:
A method of auditing operation of a television appliance consistent with certain embodiments involves detecting an event that triggers an audit; generating a fingerprint value, wherein the fingerprint value is function of the television network characteristics at an authorized installation location; comparing the fingerprint value with a stored reference value; if the fingerprint value is within specified limits of the stored reference value, permitting the television appliance to carry out a normal operational function; and if the fingerprint value is outside of specified limits of the stored reference value, inhibiting the television appliance from carrying out a normal operational function. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
