Abstract: 다계층식 데이터 스트림의 계층들 사이의 계층간 의존들의 신호전달이 설명된다. 한편으로는 계층간 의존들의 잠재적인 다양성의 너무 강력한 제한 및 다른 한편으로는 계층간 의존들의 너무 복잡한 시그널링 사이의 뛰어난 절충이 기본 계층 ID에 의해 표현 가능한 상이한 값들의 쌍들 사이의 상호-의존들을 나타내는 제 1 상호-의존 구문 구조 및 확장 계층 ID에 의해 표현 가능한 상이한 값들의 쌍들 사이의 상호-의존들을 나타내는 제 2 상호-의존 구문 구조에 의한 계층간 의존들의 기술에 의해 발견되었는데, 기본 계층 ID 및 확장 계층 ID는 다계층 데이터 스트림의 부분들이 관련된 층들을 지수화한다. 이러한 개념에 따르면, 한편으로는 시그널링 가능한 계층간 의존들의 증가된 다양성 및 다른 한편으로는 계층간 의존들의 시그널링을 위한 감소된 부가 정보 사이에서 강조가 이동될 수 있는데: 예를 들면, 각각 공통 기본 계층 ID를 갖는 계층들의 세트들이 "클러스터들"로 불리고, 동일한 제 2 상호-의존 구문 구조는 제 1 상호-의존 구문 구조를 통하여 서로 관련된 모든 클러스터 내의, 그리고 모든 클러스터 사이의 상호-의존들을 조절하도록 사용될 수 있다. 대안으로서, 한편으로는 클러스터들 내의, 그리고 다른 한편으로는 상이한 클러스터들의 계층들 사이의 계층들의 상호 의존들을 기술하기 위하여 제 2 상호-의존 구문 구조의 두 개의 인스턴스 생성이 사용될 수 있다. 증가된 다양성 또는 감소된 부가 정보 오버헤드에 대한 강조와 관계없이, 상호 의존 시그널링 개념은 시그널링 오버헤드를 낮게 유지하도록 야기한다.
