Hierarchy Embedded Content and Content Descriptors as Basis for Cross-Media Applications

摘要: The main goal of Cross-Media technology is to provide seamless delivery and access digital content, enabling optimal, user centred multi-channel cross-platform media services. Regardless the nature channel, homogeneous or heterogeneous, regardless platform, should be accessible efficiently at optimum quality over full available bandwidths independently terminal capabilities. If we accept that such services will based on applications are both network aware also aware, it necessary focus crucial issues related content processing. In this paper, argue development efficient underpinning systems need what call hierarchically embedded metadata. presented discussion relates engineering side describes how can used facilitate, if not achieve, overall concept. Three examples combining technologies ongoing developments produce metadata presented. Their application in discussed results computer experiments aiming demonstrate suitability these techniques reported.
