An overview of Blu-ray Disc application format for HD-movie distribution

1．DVD格式及其局限众所周知,DVD是一个非常成功的格式规范,在短短的几年里,它迅速地取代作为电影发布的VHS或 VCD格式而成为了市场的主流。但是,随着日益增长的应用需求,DVD格式所固有的局限性也越来越明显。比如:

Blu-ray Disc (BD) is the next generation optical dise format, currently being standardized by a large consortium of leading CE, PC, authoring companies and major movie studios. BD offers more than five times the capacity of DVD at 25 GB and 50 GB (dual layer). The BD application format addresses the limitations of DVD-Video by providing a complete user experience. The high storage capacity guarantees the best quality HD video available to the consumer. BD standardizes how content publishers can include executable applications on the dise to realize fully enhanced interactivity. This document will outline the aim of the BD-ROM standard and the design policy and introduce examples of specific functions.
