摘要： A method and apparatus within a television receiver for electronically aligning signals within the receiver by controlling support circuitry for an IF module. A control voltage source controls both video alignment and picture IF (PIF) mute functions. The DAC is coupled to a video level control circuit within the video amplifier circuitry of the television receiver. The control signal controls both the video level as well as a PIF mute circuit.

摘要： A dynamic component to input signal mapping system is disclosed that receives different types of input signals applied to a number of components and provides resultant output signals. The system includes input ports receiving the input signals, output ports providing the output signals, and a number of components processing the input signals, each of the components having at least one input and one output. The system includes a test signal source coupled to the components. Additionally, a signal analyzer coupled to an output of components analyzes response signals output from the components in response to test signals. The system is operative to map at least one component to receive at least one input signal based on the analyzed response. The system allows components on a semiconductor chip to be dynamically reconfigured for optimal processing of different types of signals, such as video and audio signals.

摘要： A signal of a desired channel is selected by a tuner from digital broadcasting is received by an antenna. The condition of the radio wave received by the antenna, which is judged from an AGC signal of the signal of the channel selected by the tuner, a Sync signal detected by a synchronization establishment unit and the number of errors which have not been corrected by a forward error corrector 10, is displayed on an indicator. The receiving direction or position of the antenna can be easily decided on the basis of the condition of the received radio wave of the antenna, which is displayed on the indicator, so that received video has a C/N within thresholds.

摘要： Combos comprising a display and a video recorder, which avoid a very bright image when switching from a standby recording mode to an on mode. In order to reduce cost, some combos include only one video circuit which is used by both the television and the video recorder, and which notably controls the level of its output signals directed to the display. This control is realized using a feedback loop that provides a feedback signal from the display. To avoid displaying a very bright image when switching the combo from a standby recording mode to an on mode, an amplification control circuit progressively revives an amplifier of the display.

摘要： A method for controlling a data set-up system in a display device comprises the steps of: maintaining an off-mode when electric power is supplied to the display device in order to store operation mode data in a memory; reading out predetermined identification information indicating a storage state of the operation mode data in the memory in the off-mode; comparing reference identification information, indicating a storage state of the operation mode data stored in a microcomputer in which the display device is normally operated, with the identification information in the off-mode data; and controlling operation of the display device according to a result of the latter comparison. With the above method, and with a data set-up system performing functions corresponding to the above steps, breakdown of a circuit due to damage in operation mode data is prevented.
