Abstract

The ISDB-T(Integrated Service Digital Broadcasting Terrestrial) can be used in the multipath and impulsive noise, also it provide good performance over mobile reception environment since it use the OFDM(Orthogonal Frequency Division Multiplexing) based transmission technology and time interleaving technology. One segment and full segment are divided according to the number of the assigned segment. And one-segment broadcasting receiver can design and implement without high levels of technology than the full-segment broadcasting receiver using 64QAM(64 Quadrature Amplitude Modulation) since it uses QPSK(Quadrature Phase Shift Keying) modulation/demodulation. However, it has a constraint in the display size and resolution due to data-rate limits. In this paper, we design and implementation of full-segment ISDB-T receiver module which support HD resolution for set-top box, digital TV, navigation. In experimental results, the implemented full-segment ISDB-T receiver module was satisfactory for all of the desired functions.

ISDB-T(Integrated Service Digital Broadcasting Terrestrial)는 OFDM(Orthogonal Frequency Division Multiplexing) 기반의 전송기술 및 Time Interleaving 기술을 사용하고 있기 때문에 다중 경로 및 Impulse Noise에 대응 가능하며, 이동 수신 환경에서도 어느 정도 양호한 성능을 나타낸다. 원세그(One-Seg), 풀세그(Full-Seg)는 할당된 세그먼트 개수에 따라 구분하며, 원세그 수신기는 변복조 방법으로 QPSK(Quadrature Phase Shift Keying)를 사용하기 때문에 64QAM(64 Quadrature Amplitude Modulation)을 사용하는 풀세그 수신기와 비교하여 높은 기술력 없이도 구현 가능하지만, 영상 데이터율의 한계로 화면 사이즈와 해상도의 제한이 크다. 본 논문에서는 셋탑박스, 고정형 TV, 일체형 네비게이션 등에 적용 가능한 HD급 해상도를 지원하는 풀세그 ISDB-T 방송 수신 모듈을 설계하고 구현한다. 실험을 통해 개발된 풀세그 ISDB-T 방송 수신 모듈의 기능이 정상적으로 동작함을 확인하였다.
