    Layouts for all possible shapes of Arabic alphabet characters are proposed for implementation using 5×7 dot matrices. A novel method for character generation is explained that reduces the total number of fonts required, thus reducing the size of the ROM. This system makes possible the display of legible text in its prevailing form. Since numerals present no problem of interconnection and of ... View full abstract»

    To effectively suppress deficiencies associated with the interlaced scanning, which yields a poor result in terms of the vertical picture resolution, a practical motion adaptive pro-scan line interpolator was developed. The system is composed of an intrafield interpolator, an interfield interpolator, three contour compensation filters, and a motion detector. For still pictures, the interpolated li...

    A practical hardware design of a two-dimensional (2D) analog filter proposed by M.A. Sid-Ahmed (IEEE Circ. and Syst., vol.36, p.153-4, Jan. 1989) is developed. The structure is implemented using charge coupled device (CCD) analog shift registers and wideband operational amplifiers. The operation of the filter is demonstrated by processing TV video images in real time. The 2D analog approach is eva... View full abstract»

    The authors investigate the mutual compatibility of the usual traffic announcement analog secondary broadcasting ARI (auto radio information) service and simultaneous digital secondary service, known as the radio data system (RDS), evaluating cross-interferences in the standard VHF-FM receiver without coherent detection. On the basis of the analysis and computer simulation the authors conclude tha... View full abstract»

  • Motion adaptive field rate upconversion algorithms for 900 lines/100 Hz/2:1 displays

    Publication Year: 1990, Page(s):149 - 160
    Cited by:  Papers (6)  |  Patents (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (812 KB)

    An algorithm for motion adaptive field rate upconversion is described. It applies one of two low-pass vertical filters to the source signal, depending on whether the source is moving or static. The theory justifying this approach is also presented. In the case of high-definition multiplexed analog component (HD-MAC) signals, the motion adaptive control can be derived from the transmitted digitally... View full abstract»

  • Two dimensional adaptive comb filter for IDTV with constant peak amplitude response

    Publication Year: 1990, Page(s):115 - 120
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (296 KB)

    A recursive adaptive comb filter structure is proposed that is composed of an infinite impulse response (IIR) filter with a peak amplitude response that is independent of the feedback gain (k). This feature avoids signal overloading in the receiver and in the encoder when the selectivity of the filter is high (k factor is high). Two chrominance and two luminance filter responses,...

  • True information television (TITV) breaks Shannon bandwidth barrier

    Publication Year: 1990, Page(s):142 - 148
    Cited by:  Papers (7)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (440 KB)

    Concepts from artificial intelligence and learning theory are proposed for use in a knowledge-based true information TV (TITV) system. In a knowledge-based TV system a store of images is learned prior to transmission. In learn mode an image from a television camera is stored into an encoding list which is then copied to a retrieval list at the receiver. The resulting transmission bandwidth is not ...

    A microprocessor-based controller for a vehicle air-conditioning system is described. It consists of a control unit resident in the vehicle to control the on/off switching of the engine and the air-conditioning unit. The control unit consists of a control panel which serves as a medium for the user to communicate with the microprocessor and a display to provide feedback to the user. A remote contr...

    A highly integrated compact disc (CD) decoder is described. The chip contains all the decoding functions, digital filtering, bit-stream stereo digital-to-analog (D/A) conversion, and analog post-filtering. The design makes use of a CMOS process that results in its having a single 5-V supply, an extended operating temperature range, and low power consumption to make the IC suitable for portable and...

  • Error performance for D-MAC data services

    Publication Year: 1990, Page(s):57 - 65

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (440 KB)

    Options for error protection within the D-MAC packet format are discussed. It is proposed that the packet-type byte be encoded using frame error correction (FEC), thereby increasing the robustness of the packet. Once FEC for the packet-type byte has been allocated, the choice of FEC for data broadcasting is limited to block codes whose lengths are integer multiples of the information block length....

    A bar matrix approach for electronic display of alphanumeric Hindi characters is described. The proposed layout consists of just 32 elements (which include the provision for matras) and thus gives rise to simpler circuits as compared to existing schemes. Schemes for implementing displays using light-emitting diodes (LEDs) or liquid-crystal displays (LCDs) are noted. Details of the CRT display of c... View full abstract»
