Run-Length Coding과 Huffman Coding을 이용한 영상 압축기의 하드웨어 설계

In this paper, we modify Run-Length Coding(RLC) and Huffman Coding(HC) algorithm for use of image compression and design as a hardwired architecture. The algorithm of RLC and HC compresses different area of Multi-Resolution Analysis(MRA) that is represented by Discrete Wavelet Transform(DWT)[1-2]. RLC compressor and decompressor is simple so that is designed like a data-path flow. HC compressor's scheme is composed of 2 stage, the first one is generation of Huffman Tree. That needs many computations and times so that uses internal memory MACRO. The second one is making binary data using Huffman Tree. The decompressor of HC is also designed simply like that of RLC decompressor's data-path flow using Huffman Tree.

This study is to investigate the characteristics of products on mixing ratio of raw materials for scoria tile manufacturing. The water absoprtion of scoria tile decreased as scoria particle size decreased and a ratio of scoria/sand increased. And also thee water absoprtion of tile decreased as an amount of cement decreased. Smaller scoria particle size, smaller ratio of scoria and sand, and larger amount of cement enhanced strength and thermal conductivity of scoria tile. The surface pattern of scoria tile became various figures as a ratio of scoria and sand increased. Well mixing of large and small particles made surface pattern of tile diverse.

Biliary ascariasis results not only in biliary tract disease, but also in secondary stone formation, hemorrhage into biliaty tract, acute cholecystitis, biliary perforation, invasion to pancreatic duct, pancreatitis, he%atitis, and liver abscess. In recent, we experienced a case of biliary ascariasis with concomitant biliary stones, which was identified by ultrasonogram percutaneous transhepatic cholangiography, and computed tomography, thereby reporting it herein with a review of literatures.

Internet telephony provides voice communication services with added flexibility for multimedia extension at a lower cost compared to traditional telephone systems. We implemented an internet telephony system as an overlay network without a centralized server, using a distributed hash table (DHT). Compared to the current server-based internet telephony system, our system is fault-tolerant, scalable, and can be flexible extended to various services and advanced to integrated service. To demonstrate the high flexibility of our DHT-based internet telephony system, we made our system cooperate with web servers. Web users can check up others online states and establish voice communication sessions to online users at a mouse click. This technology can be tipplied to more complex services such as multimedia messaging or video conference service.

디지털 설계에 적합하도록 수정된 Anti-cloche 필터를 가진 디지털 SECAM encoder의 설계
이민우,김주현,강봉순 東亞大學校附設情報技術硏究所 2005 情報技術硏究所論文誌 Vol.12 No.2
This paper presents a new design method of Sequentiel Couleur Avec Memoire (SECAM) which is one of the normal broadcasting standards. The analog SECAM encoder is difficult to make a digital hardware because of a characteristic of Anti-cloche filter, pre-emphasis filter and FM modulation. So this paper proposes the modified filter and the rearranged FM modulation method for digital SECAM encoder. The proposed method makes it possible that the SECAM encoder can be implemented by a digital system like as National Television Standards Committee (NTSC) and Phase-Alternate Line (PAL).
ITU-R BT.470 표준을 만족하는 수정된 디지털 Video encoder의 설계
이민우,김주현,강봉순 東亞大學校附設情報技術硏究所 2005 情報技術硏究所論文誌 Vol.12 No.2
In this paper, we propose a modified design method of multiple standards video encoder which is supporting the National Television Standards Committee (NTSC), Phase-Alternate Line (PAL) and Sequentiel Couleur Avec Memoire (SECAM) broadcasting standards. The proposed encoder can make various broadcasting standard signals, such as NTSC, PAL and SECAM by using the appropriate sub-carrier and bandwidth. Also, in order to separate broadcasting signal into the luminance signal and chrominance signal, the proposed video encoder has Discrete Time Oscillator (DTO) and Low Pass Filter (LPF). So the signal processes with same function can be shared. According to the above state, we expect that the proposed video encoder could increase the hardware efficiency by using the improved method. Moreover, the proposed encoder uses a modified anti-cloche filter and SECAM data flow for applying the SECAM encoding algorithm to digital processing system. So, the proposed encoder can support the NTSC, PAL and SECAM which are using QAM modulation and FM modulation, respectively.
