ABSTRACT:
A broadcast signal receiver retrofit apparatus that receives broadcast signals, detects rating or category codes therein and compares the detected codes to a setting set in the retrofit device. If the comparison indicates that the incoming signal has a rating greater than that set or is of an undesired category the broadcast signal is blocked or an audio or visual alert is given. The retrofit device may be tamper-resistant to prevent disabling the device.
