    A description is given of a still video transceiver that transmits full-colour still pictures to anywhere in the world over the general world-wide telephone networks. The system uses highly efficient picture coding that compresses picture data to about 3 bit/pixel with little degradation of quality. This accomplished by the combination of discrete cosine transform (DCT) and entropy coding. Highly ... View full abstract»

    A fully integrated satellite tuner is described that can receive all channels from European satellites transmitted using PAL, SECAM, or D2MAC. The main receiving unit is connected to two antenna amplifiers that separate the left and right signal polarizations. Two low noise amplifiers are installed at the parabolic antenna, and establish a low-loss match for different lengths of antenna cable. The... View full abstract»

    A digital field memory was used in a MOS video camera imager as an electronic variable shutter to obtain variable exposure time in the range from 1/5000 to 1/2 second. A 1.5 Mb field memory was used with a 280-kilopixel MOS imager. The memory was inserted between a gamma corrector and an encoder, so that quantizing noise was minimized. An inexpensive system was developed with 6-bit digitization fo... View full abstract»

  • Digital IC functions with differential cascode voltage switch circuits

    Publication Year: 1988, Page(s):905 - 907
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (152 KB)

    A circuit-design technique for CMOS differential cascode voltage-switch (DCVS) circuit cells is briefly described. The cells are implemented in CMOS technology. DCVS and conventional gate logic implementations are compared. It is reported that the CMOS DCVS circuit cells require a smaller layout area than conventional gate logic. In the DCVS circuit of this example, 48% less silicon area was requi... View full abstract»

    A bar-matrix layout for displaying English alphanumeric characters and Greek alphabetic characters is presented. The layout uses 14 segments and two dots (giving a total of 16 elements) and is designed so that, with selective illumination of various elements, all the numeric and alphanumeric as well as Greek alphabetic characters can be displayed along with some special symbols. The display requir... View full abstract»

    A single-chip NMOS data line decoder for the European Video Programming System (VPS) is described. Video cassette recorders with a built-in VPS receiver can record a TV program under the control of a TV transmitter broadcasting an identification code along with the actual program. The code is transmitted in TV line 16 (the European Broadcasting Union data line) during the vertical blanking interva... View full abstract»

    A technique is proposed to align automatically a color television designed with a new family of integrated circuits that incorporate internal control registers which may be a set using a serial bus. Registers internal to the various components of the system store digital values which are converted by internal digital-to-analog converters to analog control voltages and currents. All of the register... View full abstract»

    Examples are given to show how modulation coding for magnetic recording channels can be used to generate various codes for compact disc recording. The particular (2,10) code now used in compact discs is known as eight-to-fourteen modulation (EFM). The overall rate is 8/17, however, since three code symbols are inserted between each block of 14 code symbols to ensure that the entire sequence satisf... View full abstract»

    It is argued that the use of matricial scanning, at the emission and reception levels with charge-coupled device (CCD) sensors and flat panels, allows for the consideration of synchronous systems for real-time stereo television viewing without glasses or lentricular networks. A summary is given of the six major advantages in using integral matricial scanning. These are: (1) better use of the passi... View full abstract»

    A general overview is presented of the FMX stereo broadcasting system that provides reduction of background and multipath noise without a loss of stereo separation. The FMX system reduces noise in stereo reception by compressing the stereo difference signal before transmission and expanding it to its original dynamic range at the receiver. The system uses the standard FM stereo composite format wi... View full abstract»
