Abstract: An emergency alert message is included in a cable broadcast signal. The emergency alert message includes major and minor details channel numbers associated with a details channel. A details channel number is configured based on the major details channel number when the minor details channel number is set to a null value. Next, it is tuned to a channel frequency of a digital cable channel corresponding to the details channel number when the details channel number exists in a digital channel number list. Alternatively, the emergency alert message includes a details channel source field which indicates whether a details channel is a digital or an analog channel. Then, it is tuned to a channel frequency of one of a digital cable channel and an analog cable channel based upon a value of the details channel source field.

For example, different media content may be selected in response to the received broadcast data. The action may also relate to modifying the playback of the media content in response to the broadcast data. The device may also be configured to quantize values into ranges for selection of the appropriate media as well as modify playback of the media in response to the broadcast data.

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.

The ingress monitoring device (400) includes a processor (430) for resolving the reverse signals into predetermined sub-bands at a first resolution. A power computation circuit (435) computes a power level for each of the sub-bands.

Abstract: An interactive entertainment system enables presentation of supplemental interactive content along side traditional broadcast video programs, such as television shows and movies. The programs are broadcast in a conventional manner. The supplemental content is supplied as part of the same program signal over the broadcast network, or separately over another distribution network. A viewer computing unit is located at the viewer's home to present the program and supplemental content to a viewer. When the viewer tunes to a particular channel, the viewer computing unit consults an electronic programming guide (EPG) to determine if the present program carried on the channel is interactive. If it is, the viewer computing unit launches a browser. The browser uses a target specification stored in the EPG to activate a target resource containing the supplemental content for enhancing the broadcast program.
