• What is AACS MCAS?o AACS LA will operate the AACS Managed Copy Authorization Service that will be

a service for Content Companies to utilize if they choose not to use a third-party or proprietary Managed Copy authorization service

o Primary functions of AACS MCAS include authorization and tracking of Managed Copies

o Content Companies will be able to use AACS MCAS to register (i.e. create) basic Managed Copy offers for consumers

o Consumers will be able to initiate and complete the Managed Copy process on a Managed Copy Machine (MCM) that communicates with AACS MCAS

o Support services for Content Companies and consumers will be included with AACS MCAS


AACS MCAS Overview

• How does it work?o The following diagram depicts the process at a high-level


AACS MCAS Overview

• What will it provide?o Content Companies will be able to…

o Define the price structure for offers

o Define offer periods to control the duration for which an offer will be valid

o Define the number of copies permitted (copy limits) for an offer

o Report on transactions made by consumers

o Access Back-office support for assistance with disc/offer registration and transaction reporting

• What is not provided?o No delivery/hosting of content

o No hosting for Content Company applications, images, etc.

Disc Registration in MCAS

• Before registering offers in MCAS, disc registration needs to be performed

7

Disc Registration

●Content Certificate ID

● Content ID

●Deal Manifest File



• Content Certificate ID (CCID) vs. Content ID (CID)o The Content Certificate ID uniquely identifies the content on a disc and is the

combination of the AACS LA assigned Applicant ID and the Content Sequence Number

o The Content ID also uniquely identifies the content and shall contain a registered number obtained from ISAN

o MCAS requires either the Content Certificate file (containing the CCID) or Content ID to be included with disc registration

o Consideration needs to be made as to which identifier is on the actual media

o It may be likely that Content Certificate files need to be obtained from disc manufacturers/replicators whereas Content IDs may already maintained within current Content Company operations

8



• Managed Copy Manifest File vs. Deal Manifest Fileo Managed Copy Manifest File (mcmf.xml)

o Used by the MCM to identify the files on the disc needed to process the Managed Copy

o Recommended to be stored on the BD-ROM disc if the BD-ROM disc is made ready for Managed Copy

o Deal Manifest File

o Used by the MCM to identify the necessary files on the disc to process the Managed Copy

o May be used in place of the Managed Copy Manifest file

o As opposed to being on the disc, this file can be uploaded via the MCAS Back-office interface

o If uploaded, it is sent to the MCM along with the offers

o It is anticipated that current BD-ROM discs may not include a properly formatted Managed Copy Manifest File that would support the Managed Copy process; however, the Deal Manifest File can be used to remedy this

o If the Deal Manifest File has been uploaded, the MCM will use it instead of the Managed Copy Manifest File

9



• Managed Copy Manifest File vs. Deal Manifest File (cont)o MCUi

o MCUi is the identifier of the Managed Copy Unit which is a particular offer of content

o Individual MCUi’s will be needed to relate each offer of content to each Managed Copy Output Technology (MCOT) being offered

o In simple terms, the MCUi is an identifier for a piece of content to be copied combined with the MCOT that can be used to create the copy. For example, a main feature on a pre-recorded Blu-ray disc that can be copied using WM-DRM/PlayReady.

10



• Serial Numberso Serial Numbers can optionally be used to further control offers

o For example, Serial Numbers can be used to control copy limits related to specific offers

o If registered, the Serial Numbers can be either:

o The PMSN included on pre-recorded media

o “Sticker Codes” provided separately from the physical media (e.g., a sticker in the packaging)

o Serial Numbers (PMSN and Sticker Codes) can be generated using a Ksn based algorithm as per AACS specifications or a different algorithm to produce un-guessable numbers

o The use of Ksn is recommended, however, when Ksn is not used, a Serial Number list must be uploaded via the Back-office interface

11


Offer Components in MCAS• Price

o Identifies the price and associated country and currency

• Serviceo Identifies the copy count limits (when Serial Numbers are used) and valid offer date ranges

o Includes references to Prices

• Service Groupo Includes multiple Service definitions

• Offero Identifies the MCUi and any Serial Number dependencies

o Includes references to Service Groups, MCOTs and Audio/Video parameters

• Offer Groupo A method of grouping offers in order to share a common copy limit

Planning Considerations

• Content Companies will need to determine…o Where to obtain and how to manage Content Certificates and Content IDs for

discs

o How to create and manage Deal Manifest files

o How playlist files will be identified

o How the actual files will be created

o What internal groups/resources will structure the pricing, services and offers

o What internal groups/resources will perform the various Back-office operations

o How APIs may potentially be used and the timeframe to build client applications that use the APIs

• Release Functiono Disc, Offer, Service and Price data are created in a data staging environment

within MCAS when initially registered

o After data has been registered, a QC (quality control) verification process can be exercised to check that all data has been properly created

o After verification, a release function in the Back-office interface is used to migrate the data from the data staging environment to production where it will be available to consumers

Glossary of Terms

43

Term Definition

Back-office The application used to interact with AACS MCAS. Back-office users are AACS, Content Companies, and Alta Resources.

Content Certificate ID

The concatenation of the Applicant ID and the Content Sequence Number. AACS LA assigns a unique Applicant ID to each adopter who submits a request to AACS LA to create a Content Certificate. AACS LA assigns a Content Sequence Number to uniquely identify the Certified Content amongst that applicant’s content. The CCID is contained on the media and sent to MCAS by the MCM. MCAS requires either a CCID or a CID to be present.

Content ID The Content ID uniquely identifies the AACS Content to the Remote Server in an on-line transaction. The Content ID shall contain a registered number obtained from ISAN.If it is present and needed by the Managed Copy Server to distinguish between two different discs in terms of the Managed Copy obligations associated with each disc (as defined in the AACS License), then they shall have different ISAN or VISAN (versioned ISAN) numbers. The CID is contained on the media and sent to MCAS by the MCM. MCAS requires either a CCID or a CID to be present.

KSN A value used in the generation of serial numbers. AACS MCAS uses the KSN as a method to validate KSN generated serial numbers.

MAC Message Authentication Code

Managed Copy

Managed Copy is a mandatory feature included in the AACS Specification that allows consumers to make personal copies of discs protected with AACS.

Manifest file The Mcmf.xml file is an unencrypted file located on the Blu-ray disc that stores data used for Managed Copy. It contains the Content ID of the disc and any offers shipped with the disc.

MCM Managed Copy Machine. A consumer component (hardware or software) that creates a managed copy. The MCM is either tied to a licensed player or can exist as a stand-alone application. (MCM-enabled player/device) MCM connects with the Managed Copy Authorization Server through the Internet. MCM uses MCAS to authenticate the disc, receive authorization to make copies, and get offer information. Consumers use the MCM UI to view and accept offers, make payments, and make copies of the discs they own.


Glossary of Terms

44

Term Definition

MCOT Managed Copy Output Technology. Types of protection technologies that have been defined and approved by AACS LA for creating a Managed Copy. These are:

• AACS Prepared Video• AACS Recordable Video• Bound Copy Method• Content Protection for Recordable Media (CPRM)• MagicGate Type-R Secure Video Recording for Memory Stick PRO (MG-R(SVR) for M.S. PRO)• WMDRM v10 or later (including PlayReady).

In MCAS, the AACS Administrator configures the MCOT output types that are available in the system. Additionally, an MCM must support an MCOT in order to display an offer that requires the use of that MCOT.

MCU Managed Copy Unit. Specific pieces of content to be copied as part of offers retrieved from the Managed Copy Service or the disc Manifest file.

MCUi A label used to identify a Managed Copy Unit and the MCOT that can be used to create the copy.

PMSN Pre-recorded Media Serial Number. 128-bit value used for generating a MAC. The Pre-recorded Media Serial Number is optional for BD-ROM discs. If the media is an optical disc, it might be recorded in the Burst Cutting Area to enable Licensed Replicators to record unique values for each disc.

Serial Number

This is a value provided to the MCAS to identify the particular disc being copied.The Serial Number is either:

1. The PMSN included on pre-recorded media2. Provided separately from the physical media (e.g., a sticker in the packaging)3. Not provided

It is required that a Licensed Replicator use a Serial Number that is not easily guessed by the end user. If Managed Copy offers are dependent on the Serial Number, then Content Owners using the default Managed Copy Server either shall identify a list of valid values for the Serial Number, or these values shall conform to the constraints described in AACS Spec_Precorded_Final_0.952.pdf pages 42-43.

Sticker Code Any non-PMSN-based Serial Number that is entered by the end user. A typical example is a sticker associated with the packaging of the media.
