摘要： A filtering method and apparatus in which an input signal is subjected to an analog filtering step, then an analog to digital conversion step and finally a digital filtering step to produce a filtered output signal. The pulse response of the digital filter is the mirror image of the pulse response of the analog filter and the cascaded filtering steps result in a filtered output signal which exhibits little or no group delay or phase distortion. The digital filter may be a FIR filter. Also disclosed is a phase error correction method whereby a pulse is inserted into a circuit or data stream prior to a group delay imparting device or function, a pulse response of the group delay imparting device or function is measured prior to a phase correcting device or function, mirror image filter coefficients are calculated using a window function and then incorporated into a phase correcting filter arrangement.

摘要： An East-West switching transistor is coupled between a flyback transformer primary winding and a horizontal deflection output transistor circuit to control retrace energy to obtain an East-West modulation of the deflection current amplitude as required for East-West pincushion raster correction. A pair of series coupled first and second capacitors forming a capacitive voltage divider are coupled to a retrace resonant circuit that includes the deflection winding via a sampling switch, during a first half of a retrace interval, to produce a first ramping capacitor voltage in the first capacitor from a portion of a retrace pulse voltage. The first capacitor is coupled to an East-West pincushion raster correction current source for producing a second ramping capacitor voltage in the first capacitor that ramps in an opposite direction. A comparator is responsive to the capacitor voltage for controlling a conduction interval of the East-West switching transistor.

摘要： A higher order phase loop filter includes an integrator consisting of an adder (25) and a delay element (31) arranged in a feedback loop between the output port of such adder and one of its input ports. Signal to be filtered is applied to a second input port of the adder. A detector (30) is coupled to the output of the adder to detect limiting values, which, when detected, conditions the detector to reset the current value in the delay element of the integrator to a fixed value such as zero. Resetting the delay element momentarily lowers the order of the filter and speeds system response time in the presence of noise.

摘要： A block-matching method for generating motion vectors performs block matching on successively higher resolution images by refining motion vectors determined in a lower resolution image. At respective higher resolution images, search areas of limited search range are defined via a motion vector associated with corresponding image areas in the immediately lower resolution search. For at least one level of image resolution, the search blocks are overlapped to provide a plurality of search areas of limited search range for performing block matching searches for each block in the next higher resolution level.

摘要： A method and apparatus for generating an interactive component data stream, representing an application program, for an audio video interactive (AVI) composite signal, is disclosed. The method comprises the following steps. First, program files representing the application program are generated. Then, flow data defining the data structure of the interactive component is generated. Finally the data stream is generated by selectively inserting program files into the data stream in response to the flow data. Apparatus for generating such an interactive component data stream comprises a source of program files representing the application program and a source of flow data defining the data structure of the interactive component. A flow builder selectively inserts files from the source of files into the interactive component in response to data from the flow data source.

摘要： A phase detector of a phase-lock-loop circuit measures a phase error between an output signal of an oscillator and a synchronizing signal. When a difference between the phase error that is measured in a pair of horizontal line periods exceeds a first magnitude, that is indicative of phase error inconsistency, the phase of the oscillator output signal is not corrected and the phase-lock-loop circuit operates in an idle mode of operation.

摘要： A digital video signal processing system includes apparatus for concealing errors which might occur in reproduced images due to image data lost during signal transmission. The system includes circuitry for detecting transmitted video data, generating error signals if errors are present in segments (transport blocks) of the received data, and excising segments having errors from the data stream. The received data is applied to a decoder/decompressor system which decodes and decompresses the transmitted video data according to a predetermined sequence and applies the decompressed video data to a memory (for subsequent display or recording, etc.). The decompressor is responsive to the error signals for altering the predetermined sequence.

摘要： A select line scanner for a liquid crystal display includes a plurality of cascaded stages each having an input terminal and an output terminal. Each stage includes a push-pull output circuit including pull up and pull down transistors driven with separate control signals. A further transistor has its conduction path coupled between the control electrode and a point of potential of sufficient value to turn the pull up transistor off. The control electrode of the further transistor is coupled to an output of a succeeding one of the cascaded stages to insure that the output of the respective stage cannot drift to an on state.

摘要： Organ pipes distortions, caused by parasitic ringing in a horizontal deflection current are suppressed by forming a current pulse in a current injection arrangement. The current pulse is coupled to a junction terminal between a terminal of the horizontal deflection winding where a high retrace pulse voltage is developed and a low voltage terminal of a linearity correction inductance. A high voltage terminal of the linearity correction inductance is coupled to a horizontal output transistor. The current pulse begins prior to the end of retrace and ends during the trace interval. A modulation network is coupled across the linearity correction inductance for providing a low impedance current path to the current pulse.
