Abstract: Detecting tampering of an incoming cable to which a network interface unit (NIU) is connected by testing for the reflected signal that is present when the signal being transmitted to the head end is not connected to a properly terminated coaxial cable. In particular, by comparing the phase of the transmitted signal from the NIU with that of the reflected signal, a distinction can be made between a signal that travels many feet before being reflected back and a signal that reflects back right or near the connector of the NIU. Only the latter is used as a stimulus to indicate tampering since the first is likely caused by cable personnel disconnecting the cable further into the network. The key difference between the two types of reflected signals is the time delay of the reflect signal with respect to the transmitted signal from the NIU.

If the receiver can successfully establish a secure connection with the pay-TV service provider, vendor, or credit card provider and the billing information is successfully transferred, then the merchandise can be shipped or the appropriate signals can be sent to the receiver to activate the service that the customer has selected.

Abstract: A method and system are provided which allow for automatic execution of applications on a receiving station (109). As applications may provide their own interface, this interferes with the desired consistent interface a user has when “zapping” from channel to channel. Therefore, execution of applications is disabled when a user selects a channel, and enabled whenever it is determined that the user is actively viewing the selected channel. This happens when, for example, the channel identifier (202) is removed from the screen, or the last element of a menu bar (203) or other on-screen display element is erased. A timer, reset whenever the user provides input, and increased every second, can also be used. When the timer exceeds a certain value, it can be assumed the user wants to view the selected channel, and application execution can be enabled.
