- Abstract
- 레이어드 디비전 멀티플렉싱을 이용한 방송 신호 프레임 생성 장치 및 방법이 개시된다. 본 발명의 일실시예에 따른 방송 신호 프레임 생성 장치는 코어 레이어 신호 및 인핸스드 레이어 신호를 서로 다른 파워 레벨로 결합(combine)하여 멀티플렉싱된 신호를 생성하는 결합기; 상기 멀티플렉싱된 신호의 파워를, 상기 코어 레이어 신호에 상응하는 파워로 낮추는 파워 노멀라이저; 상기 코어 레이어 신호 및 상기 인핸스드 레이어 신호에 함께 적용되는 인터리빙을 수행하여 타임 인터리빙된 신호를 생성하는 타임 인터리버; 및 피지컬 레이어 파이프들(Physical Layer Pipes; PLPs)의 사이즈 정보 및 상기 코어 레이어 신호와 상기 인핸스드 레이어 신호에 공유되는 타임 인터리버 정보를 시그널링하기 위한 프리앰블을 포함하는 방송 신호 프레임을 생성하는 프레임 빌더를 포함한다.
