Abstract: An apparatus for controlling a digital transport stream on a digital settop box has independent properties in network construction between a broadcasting HE equipment or VOD server and the settop box, by controlling network interfaces and streams for both an ATM network and an IP network on one xDSL settop box. The apparatus can smoothly cope with network construction by providing services in an ATM mode in an environment requiring high quality of service, and in an IP mode in an environment requiring a low network building cost. When the broadcasting is connected to the ATM network and the VOD is connected to the IP network, the apparatus can provide services without incorporating the networks. In addition, as compared with the ATM mode, the IP mode processes decapsulation and IP routing of an MPEG transport stream packet in a software type, and thus does not require special hardware. That is, both the ATM mode and the IP mode can be controlled in the same hardware construction as the ATM mode.

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.
