In this paper, The monitoring system for TV advertisement is implemented using video watermark. The functions of the advertisement monitoring system are monitoring the time, length, and index of the on-air advertisement, saving the log data, and reporting the monitoring result. The performance of the video watermark used in this paper is tested for TV advertisement monitoring. This test includes LAB test and field test. LAB test is done in laboratory environment and field test in actually broadcasting environment. LAB test includes PSNR, distortion measure in image, and the watermark detection rate in the various attack environment such as AD/DA(analog to digital and digital to analog) conversion, noise addition, and MPEG compression. The result of LAB test is good for the TV advertisement monitoring. KOBACO and SBS are participated in the field test. The watermark detection rate is 100% in both the real-time processing and the saved the processing. The average deviation of the watermark detection time is 0.2 second, which is good because the permissible average error is 0.5 second.

In this paper, it is implemented the monitoring system for TV advertisement using video watermark. The functions of an advertisement monitoring system are automatically monitoring for the time, length, and index of the on-air advertisement, saving the log data, and reporting the monitoring result. The performance of the video watermark used in this paper is tested for TV advertisement monitoring. This test includes LAB test and field test. LAB test is done in laboratory environment and field test in actually broadcasting environment. LAB test includes PSNR, distortion measure in image, and the watermark detection rate in the various attack environment such as AD/DA(analog to digital and digital to analog) conversion, noise addition, and MPEG compression The result of LAB test is good for the TV advertisement monitoring. KOBACO and SBS are participated in the field test. The watermark detection rate is 100% in both the real-time processing and the saved file processing. The average deviation of the watermark detection time is 0.2 second, which is good because the permissible average error is 0.5 second.

A Smart TV device is either a television set with integrated internet capabilities or a set-top box for television that offers more advanced computing ability and connectivity than a contemporary basic television set. In recent years, there has been a popularity rose up on Smart TV (Smart Television) usage at home. This paper present the intelligent production status boards using features and functions of smart TV in shop floor. With the proposed status boards, we can reduce installation and operating costs of the existing production status boards. In addition, This article present the system that can line monitoring without equipments as CC TV.

국내에서는 새마을 열차, 지하철 일부 구간에 TIT 기술 기반의 IP-TV 방송 서비스를 제공되고 있으나, 교차 실행 시간 구간에서 메모리 누수 및 오버플로우가 빈번히 발생되어 서비스의 신뢰성 약화에 주요한 원인이 되고 있다. 본 논문에서는 물리적 실행 환경이 열악한 TIT 기반의 IP-TV 플랫폼의 연속 동작의 신뢰성을 향상시키기 위해 Monitoring module과 Reset module을 개발하고 재생 시간이 실험을 통해 7.2% 향상시킬 수 있었다. 특히, Monitoring module은 기존 시스템(8)의 문제점인 S/W Fault에 기인된 Dead Lock 상태를 극복하기 위해 H/W기반의 Reset Module을 추가하여 서비스 차원의 결함 허용(Fault Tolerance)을 제공하였다.

This paper presents the necessary elements and data flow in developing a monitoring system of energy usage for apartment houses with a Smart TV. Energy consumption data in each home are collected and analyzed in the HUB station by way of measuring instruments. And the amount of energy usage, such as electricity, gas, hot water, heating, water and other utilities are displayed through the Smart TV application. Energy consumption Database in the HUB station are processed and displayed in the browser of a Smart TV through XML, JAVASCRIPT and Flash. Smart TV users can get the energy consumption status through the energy consumption analysis display of the Smart TV application and improve the energy efficiency by comparing the usage patterns with neighboring houses. And the application display energy usage information, consumption ranking, rates to user as well. Furthermore, usage of last month or year can be compared to help to reduce the energy usage. The proposed system can provide the information about the amount of energy use to be reduced and the warning on the waste of energy.

The purpose of this study was to analyze information about food and nutrition topics presented throughout the television broadcast media, thereby suggest the optimal communication method to give right information to the general public. To perform this study, total sixteen monitoring people were recruited and trained through monitoring practice before and during the study . Five domestic TV channels were selected to be monitored, for six months. For the best efficiency, all the monitoring people were divided into 8 teams based on the regional consideration. The statistical analysis of data was completed using SAS program. The main results of this study are as follows. First, the total reporting cases of information about foods and nutrition were 237 , among which about 30% was classified as appropriate and 70% as inappropriate based on the trained monitors' evaluation. Second, the analysis of contents about incorrect informations showed that the insufficient descriptions of terminology and contents were the highest. And insufficient scientific evidences, incorrect contents excessively entertainment-oriented, no provision of alternatives , improper selection of expert advisors were followed. These results suggest that systematical monitoring should be continued to reduce the frequency of incorrect communication thereby give the right information in food and nutrition area to the general public. And there should be a closely cooperated system to provide the professional information to broadcasting production team by establishing the strategic program. In order to do that, most importantly the advisory team should be organized to professionally connect mass media to corresponding specialists. In addition, more educational programs about food and nutrition should be developed to provide right information to the general public.

1994년 미국에서 최초의 디지털 방송인 DirectTV 서비스를 시작하여, 현재 다양한 방송 서비스 분야로 확산되고 있다. 국내에서는 새마을 열차, 지하철 일부 구간에 TIT(Tranport Information Technology) 기술 기반의 IP-TV 방송 서비스를 제공하고 있다. 그러나, 구동 S/W가 교차형 연동 실행되어 프로그램의 실행이 정지되거나, 교차 실행 시간 구간에서 메모리 누수 및 오버플로우가 빈번히 발생되고 있다. 이러한 실행시 발생되는 시스템 Fault는 재생 손실 시간을 가중시켜 방송 서비스의 신뢰성 약화의 주요한 원인이 되고 있다. 본 논문에서는 물리적 실행 환경이 열악한 TIT 기반의 IP-TV 플랫폼을 감시하기 위해 모니터링 시간 구간을 형식화하고, S/W 기반의 TIT Monitor를 설계 및 구현하였다. 그리고 적용 실험을 통해 14.3%의 재생 시간이 향상되었음을 알 수 있었다.

본 논문에서는 개발된 편광방식 스테레오 모니터링(KAERI-PSM) 시스템의 성능을 평가하기 위해 6 D.O.F의 퓨마 로보트를 이용한 원격조작 실험을 수행하였다. 카메라의 관측각도를 달리하는 3가지 원격조작실험은 6명의 실험자가 힘반향 조이스틱을 사용하여 로보트 암을 (1) 직접 (2) 일반 모니터 (3) 동기방식 스테레오 영상 모니터 및 (4) 개발된 편광방식 스테레오 영상 모니터를 통하여 보면서 6가지의 조합된 방법으로 총 36번 수행하여 걸린 평균 시간과 평균 에러 발생 수를 비교하는 것이다. 실험 결과 스테레오 영상 모니터를 사용한 원격작업은 일반 모니터를 이용했을 때 보다 훨씬 짧은 시간에 정확히 수행할 수 있었으며, 물체 이동에 대한 카메라의 각도가 실험의 주요한 변수가 됨을 알 수 있었다. 또한 동기방식과 편광방식의 비교에서 속도와 정확도 면에서는 두 방식이 비슷했으나 눈의 피로도로 인한 작업의 안정성 측면에서는 편광방식이 우수함을 알 수 있었다.
