A hierarchical layered model for DVD authoring system

A hierarchical layered model for the implementation of DVD authoring system is proposed in this paper. By employing the hierarchical model, each object can be handled separately in the higher level of the hierarchy and the DVD format-specific bit stream can be generated in the lower levels. An object building tool that maintains a list of the hierarchical dependencies among DVD objects together with the actions to be applied to these objects is also proposed to ensure the consistency of the objects between the different layers of the hierarchy, and for the verification of the produced title sets, a reference player model is proposed. The issues in implementing a model for the DVD authoring system are discussed, and the needs of the authoring system model are addressed from the viewpoint of object encapsulation and data formatting. The proposed model provides an efficient structure in terms of adaptability and flexibility for DVD authoring.
