Abstract: An apparatus such as a television signal receiver, radio or other device provides an emergency alert function. According to an exemplary embodiment, the apparatus includes a tuner for tuning a channel frequency that provides emergency alert signals indicating an emergency event. A processor enables an alert output responsive to the emergency alert signals. A single user input button receives tactile user inputs to control the emergency alert function. The single user input button is the only tactile user input means integral with the apparatus that is capable of controlling the emergency alert function.

Abstract: An apparatus and a method for processing auxiliary data included in a video signal, in particular auxiliary data included in the vertical blanking interval of a television signal. The present invention recognizes that comb filtering of a television signal before processing the auxiliary data included in the television signal may cause corruption of the data. The present invention overcomes the problems associated with the data corruption by placing the takeoff point for the auxiliary data at a point in the signal path prior to the comb filtering. In an exemplary embodiment, the present invention also provides for switching between one of a plurality of signal sources while ensuring that the signal provided to an auxiliary data processor corresponds to the displayed signal and minimizing the additional hardware and software required with regard to prior art arrangements.

Abstract: A differential transconductance amplifier having a fixed value of differential transconductance provides a video output signal current directly proportional to the transconductance of the amplifier and to a difference between first and second differential video input signals supplies thereto. A pair of buffer amplifiers couples the video input signals to respective inputs of the differential transconductance amplifier via respective diode switches which provides Vber protection for the buffer transistors and provides bus isolation under power down conditions. An output circuit regulates the output voltage of the differential transconductance amplifier at a substantially fixed voltage and converts the output signal current to an output signal voltage. Advantageously, the receiver provides very accurate signal gain control unconditional stability, a wide common mode input voltage range, avoids the need for stand-by power and will not load the input bus under power-down conditions.

Abstract: In a projection television system, a blue phosphor roll-off compensation network is included in the emitter circuit of a common emitter configured transistor comprising the driver amplifier for the blue cathode ray tube. The roll-off compensation network includes a voltage divider connected between the emitter of the common emitter configured transistor and a source of a bias voltage, and a second transistor having its base connected to a point within the voltage divider and its collector-emitter path connected in series with a gain changing resistor between the emitter of the common emitter configured transistor and the source of the variable bias voltage. The voltage divider determines the level of drive current at which the second transistor is rendered conductive and thereby the point at which roll-off compensation is applied. The gain changing resistor determines the amount of compensation.
