In the apparatus provided by the present invention, a TV signal received by a tuner or a video signal supplied by a VCR is fed to a moving-average correction circuit and a first FIFO circuit.

Abstract: A standards converter converts an input video signal having time codes from a first television standard to a second television standard. The time codes are separated from the input video signal to obtain hours, minutes, and seconds values and input frame numbers. The hours, minutes, and seconds values are stored in a memory. Output frame numbers are generated in a consecutive sequence, from a first frame number to a last frame number, starting at times that are synchronized with the start of the sequence of input frame numbers. The output frame numbers are combined with the hours, minutes, and seconds values stored in the memory to generate output time codes, which are combined with the converted video signal.

Abstract: A TV graphical user interface (GUI) is provided to enable a user to input antenna location information required for setting up a dish antenna. When the TV GUI is set in a dish set-up mode, the user may activate a U.S. map button to display a map of the United States or another area on the earth's surface. When a remote pointing device is directed at a point on the map that represents the current location of a satellite receiver, the TV GUI displays a regional map that shows in more detail a region where the receiver is located. When the user selects the receiver location within the regional map, the CPU determines the latitude and longitude values of the selected location, and calculates magnetic north and elevation angles for the antenna installation. To provide the user with visual feedback, the TV GUI may indicate the city nearest to the selected location, and a distance to the nearest city.

Abstract: In a video display terminal (VDT) adapter connected to a moving picture output device, inputting means inputs, from the moving picture output device, an input moving picture signal indicative of input moving pictures having brightness which changes drastically. Connected to the inputting means, picture temporal frequency attenuator means selectively attenuates a particular frequency band of the input moving picture signal to produce a smoothly-changing moving picture signal indicative of smoothly-changing moving pictures. The particular frequency band includes human sensitive frequency components. Connected to the picture temporal frequency attenuator means, outputting means outputs the smoothly-changing moving picture signal as an output moving picture signal. The particular frequency band may lie on a range not less than 7 Hz.

Abstract: An apparatus and a method for controlling video/audio modes in a video/audio outputting apparatus is provided, in which the audio mode is automatically set in relation to the video mode selected by the user. A judgment is made whether an inputted working command code is a video mode code or an audio mode code.

Then a value is set to the video mode code thus judged, and at the same time, a value is set to the audio mode. Meanwhile, if the working command code thus judged is a an audio mode code, then it is judged as to whether it is a custom mode, a standard mode, a movie mode, a music mode or a soft mode. Then a value is set to the audio mode code thus judged.

Abstract: Sync separator and video detector circuits, including a sync tip clamp having symmetrical and non-symmetrical clamps. The symmetrical clamp clamps the input video signal to a reference voltage during composite sync pulses, so the coupling capacitor discharge current is kept small between composite sync pulses. For startup, the non-symmetrical clamp employs an operational amplifier, diode and controllable current source to charge the coupling capacitor to a minimum desired level, and to discharge the capacitor e.g. when there is a change in DC level so that the output level is too high. A sync slicing detector is also provided, using two comparators. One comparator compares the slicing level with the clamped video and produces a properly sliced composite sync output, while the other compares the clamped video with a small reference voltage and produces a fixed sync output.

Abstract: Generation of digital cursors for serial digital television waveform monitors includes inputting hexadecimal values for the cursors by an operator via a front panel. The hexadecimal values are received by a microprocessor which loads them into appropriate registers of a co-processor. The outputs of the cursor registers in the co-processor are input to respective inputs of a multiplexer together with a digital signal representing a serial digital television signal. A select signal for the multiplexer is generated by a selection circuit that is enabled by a digital cursor ON command when the waveform monitor is in a cursor mode. The selection circuit at predetermined locations of the digital signal generates the select signal so that the appropriate cursor values are inserted into the digital signal at those locations.

A capacitor (42) is arranged as a shunt across the drain-source path of the FET and creates an oscillating circuit together with the ballast inductance (5).
