The invention relates to a use of an apparatus for configuring two or more communication-related parameters in a cable modem system. The apparatus comprises a processor, a cable television signal input interface for receiving one or more cable television signals, and a cable modem termination system unit for providing access to a communication network.

In a video imaging apparatus, a camera module includes the imaging unit and an imaging control unit that controls the imaging operation of the imaging unit according to imaging control values, and the imaging apparatus main body connected to the camera module via a connection cable capable of bidirectional communication includes an image signal processing unit that outputs frame images of a video in sequence from the imaging signals and generates the imaging control values for controlling imaging operation of the imaging unit from the imaging signals. The imaging unit can determine whether the imaging control values input from the image signal processing unit via the connection cable are abnormal imaging control values under influence of noise.

A method and apparatus in a noise cancellation system that receives a noise reference signal via a noise reference signal input port, and performs at least one of procedures a and b set forth below for reducing noise in a DSL data signal transmitted on a DSL transmission line to which the noise cancellation system is coupled: a.i.) creating a noise free representation of a DSL synchronization symbol repeatedly occurring in the transmitted DSL data signal, and a.ii.) reducing the noise in the transmitted DSL data signal based on the noise free representation of the DSL synchronization symbol and the received noise reference signal, and b.i.) analyzing at least one of the received noise reference signal and the transmitted DSL data signal to identify one or more frequency bands in which to de-emphasize noise cancellation in the transmitted DSL data signal, and b.ii.) causing the noise cancellation system to de-emphasize noise cancellation in the identified one or more frequency bands of the transmitted DSL data signal, responsive to the analysis.

RF signal amplifiers are provided that include an RF input port, a switching device having an input that is coupled to the RF input port, a first output and a second output, a first diplexer having an input that is coupled to both the first output of the switching device and the second output of the switching device, and a first RF output port that is coupled to an output of the first diplexer. These amplifiers further include an attenuator that is coupled between the second output of the switching device and the input of the first diplexer.

A method and an apparatus are used to target interactive virtual objects to subscribers in a television delivery system. Programs are selected and virtual object locations are defined in the selected programs. The virtual objects available for targeting are categorized and the categories are correlated to subscriber information to determine the optimum targeting of the virtual objects. The virtual objects may be targeted based on individual subscriber information or on information related to groups of subscribers. When a frame of a program includes a virtual object location, a default or an alternate virtual object is displayed. The virtual object location may change over space or time. The virtual object may be interactive, and may be used to link a subscriber to a remote location, such as an Internet web site. An operations center or a cable headend may generate a group assignment plan that assigns the subscribers' television terminals to groups, based on factors such as area of dominant influence and household income. A retrieval plan is then generated that instructs the television terminals to select the desired virtual object for display. The television terminals record which virtual objects were displayed, and report this information to the cable headends and the operations center. The reported information is used to generate billing for commercial advertisers, and to analyze viewer watching habits. Interactive virtual objects are received by the television terminal with directions on actions to be taken upon selection of the interactive virtual object. Actions may result in the initiation of processes locally at the television terminal, or communication with a remote site for the initiation of processes to be performed remotely. The invention uses upstream data reception hardware, databases and processing hardware and software, and corresponding features in the televisions to accomplish these functions.

A camera unit includes: an image sensor; a circuit board in which a signal processor circuit to process an output signal of the image sensor is formed; a cable including at least a signal conductor element and a ground conductor element and connected at one end to the circuit board; a metal housing component to accommodate the image sensor and the circuit board therein; and a metal component disposed at the end of the cable and connected to the ground conductor element. The ground conductor element is connected to both a ground terminal of the circuit board and the metal housing component in a vicinity of the end of the cable where the cable is connected to the circuit board. The ground conductor element is connected to the metal housing component through the metal component in the vicinity of the end of the cable.

Return loss due to excessive signal reflection into a cable television (CATV) network from an inoperative or abnormally operative terminal adapter is minimized, to communicate enhanced passive downstream signals to passive subscriber devices such as “life-line” telephone sets. A predetermined termination impedance is substituted for an active branch circuit of the terminal adapter whenever reduced input voltage, over-current or under-current conditions exist in the terminal adapter.
