本文件中规定的技术是描述感官效果的描述语言和词汇。 自适应引擎不在本文档（或ISO/IEC 23005系列）的范围内。 本文件规定了描述感官信息的工具的语法和语义，以丰富视听内容: -感官效果描述语言（SEDL）是一种基于XML模式的语言，能够描述感官信息的基本结构； -感官效果词汇表（SEV），一种XML表示法，用于描述触发人类感官的感官效果，如光、风、雾、振动等。

The technologies specified in this document are description languages and vocabularies which describe sensorial effects. The adaptation engine is not within the scope of this document (or the ISO/IEC 23005 series). This document specifies syntax and semantics of the tools describing sensory information to enrich audio-visual contents: — Sensory Effect Description Language (SEDL) as an XML schema-based language which enables one to describe a basic structure of sensory information; — Sensory Effect Vocabulary (SEV), an XML representation for describing sensorial effects such as light, wind, fog, vibration, etc. that trigger human senses.
