  • Improving AM Sound: The NRSC Standard

    Page(s): x - xvii
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1031 KB)  

    On September 5, 1985, the NRSC adopted a resolution to study proposals to standardize AM transmission preemphasis and AM receiver deemphasis with the objective of establishing an industrywide AM preemphasis/deemphasis voluntary standard. After twelve months of study, on September 10, 1986 the NRSC released a draft voluntary standard that proposed a specific AM preemphasis/deemphasis curve as well as a 10 kHz standard AM bandwidth. The bandwidth specification evolved from NRSC deliberation on the causes and cures of AM interference, and ways to technically encourage the production of higher fidelity AM receivers. After a three month public comment period, the NRSC, on January 10, 1987, formally adopted this standard and authorized its publication by the National Association of Broadcasters and the Electronics Industries Association.

    Page(s): xxiii - 97
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (2658 KB)  

    Two dimensional adaptive digital decoder has been developed. This decoder samples NTSC signal using burst locked sampling clock whose frequency is 4Fsc. Also the decoder separates the NTSC signal into luminance and two color difference signals using the newly developed 2D adaptive Y/C separation. View full abstract»

  • High Quality Digital TV With Frame Store Processing

    Page(s): 98 - 108
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (4431 KB)  

    Though the existing TV standard (NTSC) is a highly sophisticated method to transmit a color television signal without a wide frequency bandwidth, it has some intrinsic problems as follows. (1) Cross-luminance (hanging dots) and cross-color interferences These are caused by the incompleteness of a luminance/ chrominance separation. Hanging dots interference is caused by the cross talk of the chrominance signal into the luminance signal. On the contrary, the cross-color interference is caused by the cross talk of the luminance signal into the chrominance signal. (2) Line flickering and coarse scanning line structure These are caused by interlace scanning. Line flickering is very obvious at the edge where the image changes its brightness in the vertical direction. The coarse scanning line structure can be observed in motion pictures very well because they have only 262.5 scanning lines a field. View full abstract»

  • Design of Multiplierless FIR Digital Filters With Two to the N th Power Coefficients

    Page(s): 109 - 114
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1260 KB)  

    A new method of multiplierless finite impulse response (FIR) digital filter design by using two to the N th power coefficients is presented. This method is based on the cascading, "local correlation" and "windowing". The basic structure of these FIR filters is discussed, and several results of such filter design are presented in this paper. View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1844 KB)  

    We have developed the digital TV system IC line-up which consists of 2 MOS LSIs and 4 Bipolar ICs. Digital signal processing is carried out in 2 LSIs with 1.5um-rule CMOS technology, by which picture quality can be improved. It has been designed for both NTSC and PAL systems and it is adaptive for double-line scanning. View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (936 KB)  

    This paper outlines the architecture of a universal controller for DSP-chips. Influenced by RISC-ideas, this VLSI standard cell shows some characteristics which are uncommon to most micro controllers. Its computing power reaches 80 million operations per second. Fabricated in 1.5p¿CMOS the cell area is less than 6 mm2 when completed with a typical memory size of 128 bytes RAM and 2 kbyte ROM. View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (2549 KB)  

    A multiplierless algorithm for calculating the convolution of a Finite Impulse Response (FIR) digital filter is presented. The algorithm is based on the partial slicing of input data vector words and performing the convolution in a distributed fashion. A fast, flexible and hardware efficient architecture for implementing the algorithm is described. Simulation results of the prototype one tap filter are presented, demonstrating the high speed capability of the architecture. View full abstract»

    Demonstration is a joint project of the National Association of Broadcasters (NAB) and the Association of Maximum Service Telecasters (MST). It was initiated two years ago with the overall objective of assuring that terrestrial broadcasters would remain technically competitive with other video media. Specifically, this meant informing the industry of the progress of HDTV development and making the Federal Communications Commission aware of broadcaster needs for the delivery of HDTV. The first phase of this project concluded earlier this year with the successful operation of a high definition television (HDTV) broadcast station WWHD-TV in Washington, DC. View full abstract»

  • Channel Matching Techniques for 2-Channel Television

    Interest and progress in the area of high definition television (HDTV) has led to a wider aspect ratio image as an integral part of the evolutionary process. Encoder systems decompose the wide aspect ratio source image into a center 4:3 image and two side panels, maintaining compatibility with existing standards (NTSC) for the center picture. Transmission schemes then transmit the center image over a standard 6 Mhz TV channel (channel 1) and the panel information over another channel (channel 2). Decoders which accept the center and panel information recombine the signals to construct the original wider image. An example of this technique is utilized in the two channel ENTSC System [1]. Due to linear distortions, various parameters such as hue, saturation, black level, gain and static time delay must be normalized in both video signals before recombination of the wide aspect ratio picture. A description of techniques which employ insertion of a training signal at the transmitter and a microprocessor at the receiver, used to control these parameters is presented in this paper.

  • An Extended Definition Television System Using Quadrature Modulation of the Video Carrier with Inverse Nyquist Filter

    Page(s): 173 - 180
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (4989 KB)  

    A QUadrature Modulating Extended definition television system -QUME- , which enhances NTSC to higher definition , is proposed. The QUME system uses quadrature modulation of video carrier with inverse nyquist filter and creates an independent transmission channel (Bandwidth : 1MHz) without using additional channel resources. One of the features of QUME is that the multiplexed signal hardly interferes with the conventional TV receivers, and another is that there is no crosstalk between the multiplexed signal and the main NTSC signal. These features enable a wide aspect ratio image to be transmitted as well as high frequency components of luminance and/or chrominance signals, while keeping compatibility with the NTSC system.
