Scalable Application Description Language to Support IPTV Client Device Independence Based on MPEG-21

This paper presents a framework and a description language to ensure application interoperability for heterogeneous IPTV client devices with different capabilities by providing application scalability. To support device independent application in IPTV service environment, we suggest a new XML schema (named Scalable Application Description Language: SADL) based on MPEG-21 DIDL (Digital Item Declaration Language).
