The increasing demand and use of computers prompted extensive studies on implementing low cost and reliable pointing devices. The use of capacitive coupling technology allows wireless pointing devices to be reliable and do not require any battery. The proposed pointing device uses capacitive coupling technology to detect both the x and y position of the mouse/digitizer and also if any of the buttons were pressed. Detail analysis of the capacitive coupling signals and its performance in both the time and frequency domains were discussed. The proposed pointing device was built and implemented. The experimental results showed potential for commercialization of the wireless pointing device and its robustness.

This paper describes a new digital NTSC TV and audio signal transmission system in which circuit configurations are simplified and made more inexpensive than MPEG 2 on the basis of the subjective evaluation of the picture quality. An NTSC TV signal and an audio signal can easily be transmitted to the receiver at the same time, since the transmission rate is kept unchanged due to the insertion of the digital audio signal into the horizontal sync pulse of the digital NTSC TV signal. The proposed system has three features. Firstly, the system could give satisfactory picture quality enough to operate consumer-use visual appliances even though the quality of the reproduced pictures is lower than that of the normal digital NTSC TV picture codes obtained at a sampling frequency of 4.00/spl times/fsc with a quantizing level of 8 bits. Secondly, the system can satisfactorily transmit NTSC TV picture codes at a low transmission rate of 50 Mbps even if such an advanced compression technique as MPEG 2 has not been used. Thirdly, the system is used for transmission of the digital audio signals which are inserted into the horizontal sync pulse of the digital NTSC TV signal. A combination of edge-emitting LEDs (ELEDs) and single-mode (SM) optical fibers enable the system to easily transmit a digital NTSC TV picture signal together with digital audio signals over the distance of 10 km through the SM optical fibers.

In this paper, we propose an estimate of face orientation by detecting the eyes and mouth on a facial image. Our purpose is to develop a new vision-based human interface technology that uses face orientation to interact with humans. Our algorithm samples a range of skin colors and dynamically updates feature templates from the current input image. In addition, we estimate face orientation from the relationship between the detected facial features' positions. As a result, our system determined the correct location of both the eyes and the mouth for all four subjects more than 94% of the time.

This paper presents the ModuleC network architecture for information appliances (e.g., televisions, stereos, and VCRs). ModuleC reverses the PCMCIA (PC card) paradigm and places the computing and networking platform on a small form factor card that externally connects to peripherals and appliances. ModuleC-equipped information appliances provide the ability to move information both within the home, e.g., between different appliances, and between the home and the outside world. This connectivity not only provides a means for exchanging application-specific information-it also provides a vehicle for replacing and upgrading the appliance software. Essentially, this platform is a footing part way between the PC ($1000-$2000) and the embedded computer ($1-S10); in particular, it brings to the embedded environment the network access and dynamic programmability features of the PC.

Video compression is an indispensable element in multimedia communications systems. We simulate the H.263 video coder and pass the compressed data through a simulated mobile communication channel. Preliminary results indicate that the error control codes, such as BCH codes, are very useful for protecting the compressed data. In addition, the error correcting capability of the lapped orthogonal transform (LOT) is also investigated.

An HDTV plasma display with a large flat screen and high picture quality has been developed. The panel specifications, performance and the system configuration are described. The display uses a newly developed 42-inch diagonal DC-type PDP (plasma display panel) with 1920/spl times/1035 display cells. To reduce dynamic false contours, the most serious impairment for picture quality of PDP displays, a new panel driving method and signal processing have been developed. As a result, high picture quality is obtained not only for still images but also for moving images. Implementation as a practical HDTV receiver is described. The display paves the way for a commercial wall-mounted 1125/60 HDTV receiver.

We propose a new PN chip clock generator which employs two synchronous counters to achieve precise control of chip clock in a CDMA code acquisition and code tracking. The proposed clock generator provides a reliable clock without any glitch. Since the chip clock generator can be easily controlled into one of the states: free running, phase advance and phase delay, it can be used for both data processing and code synchronization.

The storage capacity of a DVD is at least 8 times that of a compact disc (CD) with the same disc size. However, the higher density has led to narrower tracks and pitches (distances between tracks). This requires an improvement of the follow-up capability within limits which are not detrimental to its stability and speed of the system. In this paper, some techniques pertaining to the DVD servo control system, which are critical but not identical to the CD-ROM system are reviewed and investigated. These include the one-beam push-pull tracking method used in tracking error generation, adaptive learning control algorithm for DVD pickup spindle motor tracking, and variable speed control of the turntable brushless DC motor.

Digital images require a large amount of data to be represented. To make image storage and transmission practical and economical, image compression has become a major issue. In the past few years, several image compression methods using fractal theory have been developed. These methods promise better performances for compression. One of the most efficient approaches is based on iterated function systems (IFS), and has been promoted by Barnsley (1988). The basic idea is that an image can be reconstructed using the self-similarity it contains. A way to speed up the encoding process is to implement parallel processing using PVM (parallel virtual machine) software. The system utilizes both static and dynamic load allocations to obtain substantial compression time speedup over the original, sequential encoding implementation. In this paper, considerations such as PSNR, compression ratio, compression time versus number of processors and the workload granularity are also presented.
