從過去十年中，多媒體技術已經取得了長足的進步。因此，防止這些多媒體資料被任意拷貝也成為數位內容產業的一大挑戰。所以最近幾年出版業者與數位娛樂產業的首要任務，就是制定出有效的內容保護機制，並建立良好的數位版權管理系統。在多媒體數位內容發行系統中，物理內容發行系統是其中的一個方式，例如使用數碼多功能影音光碟或是藍光光碟…等等。而高階內容訪問系統(AACS) 則是一種用於這類高畫質數碼多功能影音光碟和藍光光碟的限制訪問與防拷貝的技術，而在這個對於數位出版商來說具有挑戰性的時代，這項防拷貝技術更是扮演了一個至關重要的角色。
在本文中，我們提出了一項針對可錄式介質的AACS防拷貝架構的分層式設計，其特點為無須從AACS的授權管理者拿到認證金鑰。這將會為非AACS的授權會員企業提供一個強大、高相容性且高性價比的內容保護機制。本文中也提及了如何在非AACS認證的影音撥放器上撥放有AACS保護機制的藍光可錄光碟的技術。藉由本論文提出的技術，將能夠方便得讓許多中小型非AACS會員企業也能夠在藍光可錄光碟上添加AACS保護。

Multimedia technology is the essential part of home entertainment and it makes a great progress from last decade. Content distribution systems are essentially content protection systems that protect premium multimedia content from being illegally distributed. So, it becomes a challenge for digital industries to give protection to their content and the physical distribution system. Devising effective Content Protection mechanisms and building satisfactory Digital Rights Management (DRM) systems have been top priorities for the Publishing and Entertainment Industries in recent years. Advanced Access Content System (AACS) is intended to restrict access to and copy protection of HD-DVD and Blu-ray, which is playing a crucial role in copyright protection during this challenging era for much-renowned companies.
In this thesis, we propose a step-by-step design that adopts the AACS copy protection architecture for recordable media, without getting key authorization from AACS LA, which will provide a robust, high compatible and cost-effective content protection system for non-AACS LA enterprise. We emphasize on how to play the BD-R with AACS protection on an unauthenticated AACS player. The result of our design is to protect the BD-R with AACS, which can be easily used by the small and medium non-AACS LA enterprises.
