The authors have conducted the research to the hybrid digital object in order to meet the need of network multimedia applications which have interoperability,standard as well as the intellectual property protection function.Put forward the hybrid digital object model HDO_IDOP(Hybrid Digital Object in IPTV DRM Operating Platform) which includes the methods,semantics and management.The Petri model is adopted to establish the rights expression model of the HDO_IDOP_REL,and the mechanism of logical inference is established which makes the rights expression to be understood and explained by machine widely.
