범용 컴퓨터가 아닌 홈 네트워크로 연결된 정보가전용 실시간 시스템에 내장되는 운영체제인 정보가전용 실시간 운영체제는 디지털 TV, 웹 TV, WebPad, PDA, Smart Phone 등에 사용된다. 그러나 정보가전용 실시간 운영체제는 선점형 스케줄링, 멀티 태스킹 및 태스크간 예측 가능한 동기화 방법 그리고 짧고 제한된 인터럽트 처리와 작은 실행 이미지 등과 같은 특징들을 갖는다. 본 논문에서는 이와 같은 특징들을 만족하는 정보가전용 실시간 운영체제를 DVD 플레이어에 적용하여 설계 및 구현한 내용을 기술한다.

In this paper, we presented the concept and some methods to watch online video clips related to a TV program on atelevision which is called lean-back media, and we simulated our concept on a PC system. The key point of this research is suggesting a new service model to TV viewers and the TV industry, which the model provides simple and easy ways to watch online video clips on a TV screen. The paper defined new tags for metadata and algorithm for the model, then showed simple example using those metadata. At the end, it mentioned the usage of the model in the digital broadcasting environment and discuss about the issues which should handle as future works.

To overcome a scarcity of radio resources to mobile broadband service, the usage of TV white space gains much attraction around the world. This paper carries out an interference analysis either by performing realistic experiments or by executing statistical Monte-Carlo simulation to exploit interference probability. The results obtained from experiments are compared to those from simulations in order to clarify the coexistence of utilization of TV band devices (TVBD) in indoor circumstances. Along the execution of our experiment in the presence of DTV receiver, we apply to a variety of transmission parameters proposed in FCC for TVBD. According to experimental and simulation works, the allowable transmission powers of TVBD systems are exploited for the plausible which are coexist on the first as well as the second adjacent frequency bands. Throughout results, it can conclude that TVBD systems can be coexisted via achieving proper transmission powers depending on the locations of themselves without showing harmful interference to DTV reception.

'정보 초고속도로'는 TV시청형태에 많은 영향을 끼치며 현재 존재하지 않는 매우 창의적인 서비스가 제공된다. 그 규모는 수천억 달러에 이르며 거대한 시장을 조성하는데 하드웨어 설비 못지 않게 소프트웨어에 거대한 자금이 투입될 전망이다.
