    Vector quantization (VQ) is a popular class of image encoding techniques which finds valuable applications in developing economical, low bit-rate video conferencing and multimedia products for the consumer's market. A new algorithm known as the side match vector quantization (SMVQ) had been proposed to enhance the visual quality of traditional VQ techniques by reducing the blocking effect based on local edge information. We show that despite the success of SMVQ in encoding still pictures, it does not perform equally well with interlaced video signals which contain motion contents. To overcome this problem, an algorithm known as the hybrid side match vector quantization (HSMVQ) algorithm which enable existing SMVQ to be applied to encode interlaced video signals with improved visual quality is developed and presented. Typical results obtained with HSMVQ, as compared to SMVQ are presented to demonstrate the feasibility of the approach View full abstract»

    This paper describes the revised versions of the three recording/playback interface systems from the previous ones. Modifications were required to meet the current HDTV transport data formats which were significantly changed in accordance with the Grand Alliance (GA) specification. The interface is also modified to accept both 8 VSB and 16 VSB modes. It has three types of interface application: the first interface is for the GA-HDTV transmitter to D3 digital VTR, the second is for the GA-HDTV receiver to HD-VCR and the third is for the HD-VCR to D3 VTR. The interface hardware was fully developed and used for the GA-HDTV systems laboratory testing in April, 1995 at ATTC and field testing in Charlotte, North Carolina View full abstract»

    The paper investigates some new systems concepts for future HDTV systems, and proposes a powerful personal computer (or workstation)-based software-oriented information management system located between the receiver and display systems of the HDTV system in order to take advantages of the high-quality display system used in multimedia information services. From the systems integration viewpoint, and information manipulation and management considerations, the information management system has been proposed at a conceptual function level, which intends to integrate a variety of HDTV transmission systems and to receive high-speed BISDN-based multimedia information services. The systems architecture for this proposed information management system has been figured out at a very high level View full abstract»

    An investigation, based on subjective tests according to ITU Recommendation 500, was carried out to correlate the TV contrast-definition parameters to the subjective quality perceived by the viewers. The results show that high definition pictures (HDTV), with reduced contrast, and standard definition pictures (SDTV), with high contrast, are of comparable quality. Tests were carried out with the HDTV design viewing distance equal to 3 times the screen height (DVD=3H). A test using the preferred viewing distance (PVD) was also carried out. PVD is a subjective parameter and a function of screen height. For the 38", HDTV, 16/9 screen used in this test, PVD was 5.2 H. The results show that the design of new displays for HDTV should guarantee a large screen with adequate contrast in order not to make the higher definition contribution ineffectual View full abstract»

    Operation of single-carrier and multiple carrier systems under conditions of deliberately introduced echoes is examined. Problems in addition to intersymbol interference, which is specifically alleviated in multiple carrier (OFDM) systems with guard intervals, are examined. It is shown that the only advantage of coded orthogonal frequency division multiplexing (COFDM) is in the case of simple binary modulation of its individual carriers, which is not adequate to carry the data required for digital television View full abstract»

  • IC design of an adaptive Viterbi decoder

    We implement an integrated circuit (IC) design for a decoder of a 64-state binary convolutional code. The decoder is based on a reduced-state adaptive Viterbi algorithm (VA) for which the decoding speed is faster than the standard VA while the error performance remains almost the same. With the adaptive VA, less bits are needed to store and to calculate the metrics of the decoding trellis and less power dissipation is needed, as compared to the standard VA. The IC design is based on a 0.8 μm CMOS technology. The number of quantization levels in the decoding is Q=8 View full abstract»

  • Power and spectrally efficient modulation for PCS and satellite TV broadcasting

    A power and spectrally efficient modulation which increases the transmit output power and reduces the interference among adjacent channel users in PCS and satellite TV broadcasting applications is presented. This modulation named filtered quadrature phase shift keying or “FQPSK” can be nonlinearly amplified using class C amplifiers allowing a 7-10 dB increase in transmit output power compared to QPSK modulated systems. This gain in the output power leads to a wider transmission coverage in satellite applications, longer battery life and reduced radiation for PCS users View full abstract»

    A prototype of a foldable-display system (FDS) that uses two active-matrix liquid crystal displays (LCDs) has been developed. The display images can be inverted and an automatic viewing-angle-control function lets users on both sides of the FDS see the image clearly. By using the FDS as a face-to-face communicator, the authors demonstrate its potential as a standard multimedia platform View full abstract»

    The purpose of this paper is to investigate and construct a new generalized framework for VOD transmission on future high-speed BISDN in order to make every multimedia-based server serve the same information service to large volume of users simultaneously by using some new concepts and mechanisms of UNIX. The socket mechanism of 4.3 BSD UNIX, playing a critical role in the framework, has been studied. The software developments have already been made. In addition, some future works on the generalized framework have been pointed out briefly View full abstract»

The objectives of the file system design are high throughput and low loss rate. A hard disk device driver and a file system are modified and tuned for A/V recording. The new file system can have up to 60% performance improvement over the traditional file system. Performance results from our experiments are presented and discussed View full abstract»

    An ultrafast, all-digital method for phase synchronization and coherent carrier recovery is presented for time division multiple access (TDMA) and code division multiple access (CDMA) burst data communication systems. A new adaptive phase tracking (APT) method, presented and analyzed in this paper, uses a hard-limited IF signal in a feed forward configuration for carrier phase detection and recovery. A novel new technique of phase window filtering is presented as a means to combat noise induced phase errors, and improved the performance of a digital controlled phase shift oscillator by 7 dB. Experimental measurements show APT provides robust bit error rate (BER) performance within 1 dB of the theoretical binary phase shift keyed (BPSK) and tenths of dBs of an ideal hard wired clock. APT achieves acquisition within one- to four-bits-5 to 10 times faster than present requirements. A low power, low cost single chip fast carrier synchronization and demodulation solution for QPSK, GMSK and GSM compatible OQPSK and Feher's quadrature phase shift keyed (FQPSK) and binary phase shift keyed (FBPSK) systems are also presented View full abstract»

    This paper proposes a novel data retrieval scheme that achieves effective utilization of disk bandwidth for designing fully interactive video-on-demand systems. The main distinctions of the proposed data retrieval scheme are (1) it requires no extra disk bandwidth to support interactive features such as fast forward search and fast backward search; and (2) it is based on a data placement scheme that can effectively utilize disk bandwidth during normal-speed playback View full abstract»
