仕様書体系を大きく分けると　配信サービス仕様群と　サービスアプローチ仕様群から構成されます。
配信サービス仕様はどのアプローチでも共通の仕様となるような構成です。
ＡＲＩＢ規格でいうと、いわゆるＳＴＤに相当する位置づけです。　
そのなかに　ＶＯＤ、ダウンロード、ＩＰ放送の仕様があります。
サービスアプローチ仕様は、　ＡＲＩBでいうとＴＲに近い位置づけで、運用規程を含んだ仕様となっています。
放送連携、インターネットスコープ、ＣＤＮスコープの３つの仕様があり、
図の矢印は、放送連携やインターネットスコープでは、ＶＯＤとダウンロードに対応できることを意味します。ＣＤＮでは、ＶＯＤ、ダウンロードに加え、ＩＰ放送にも対応します。
ＩＰ再送信だけは、１つ特別な扱いです。ＩＰ再送信は、サービスアプローチ仕様を
含んだ形で、これだけで、ＩＰ再送信サービスを実現する仕様として成立しますが、
ＣＤＮスコープの他の配信サービスとの統合運用において、ＣＤＮスコープ仕様と
関連性を持ちます。
