A HIERARCHICAL LAYERED MODEL FOR DVD AUTHORING SYSTEM

A hierarchical layered model for the implementation of DVD authoring s ystem is proposed in this paper. By employing the hierarchical model, each object can be handled separately in the higher level of the hiera rchy and the DVD format-specific bit stream can be generated in the lo wer levels. An object building tool that maintains a list of the hiera rchical dependencies among DVD objects together with the actions to be applied to these objects is also proposed to ensure the consistency o f the objects between the different layers of the hierarchy, and For t he verification of the produced title sets, a reference player model i s proposed. The issues in implementing a model for DVD authoring syste m are discussed, and the needs of the authoring system model are addre ssed from the view point of object encapsulation and data formatting. The proposed model provides an efficient structure in terms of adaptab ility and flexibility for DVD authoring.
