16. Part 1 The Chillout Architecture

17. Language requirements • Chillout is written in the Java programming language. • Java is an outstanding language • it possesses excellent cross-platform capabilities • it is supported by many international companies operating in various fields. • plenty of Open Source software Development Tools available • any other programming language could be chosen instead of Java • cross-language implementations are starting

18. Software architecture/1 • Because of the nature of Digital Media technologies and business models, only a toolkit approach for DRM can succeed • users may • chose a subset of the IDP tools • configure them (as specified in the specification) for their specific needs • ...use them straight away 

19. Applications Auxiliary library Core library Java platform Software architecture/2

20. Software architecture/3 • Java Platform Layer: • the Java running environment on which Chillout software depends on. It comprises of the Java Development Kit (JDK), Apache Tomcat servlet container the Apache Axis SOAP implementation, the Java Media Framework, etc. • Core library: • library of classes implementing the Primitive functions defined in the Technical Spec­ification. This software is normative as much as the IDP-2 specification [3], in the sense that the two are meant to be technically aligned. • Auxiliary library: • library of classes encapsulating the functionalities that every device must have when operating in a real environment. These modules may be replaced by those a developer needs. • Applications: • sample applications including a number of Devices, such as a SAV, a Content Creation Device (CCD), a License Provider Device (LPD), a Content Provider Device (CPD), etc.

21. Chillout Source code Organization

22. Part 2 The Chillout Core Library

23. Overview of the Core Library • The Chillout Core Library is made of the following classes: • the Represent classes • the Package classes • the Protocol classes

24. Chillout Core

25. The Represent Classes • The Chillout Core library provides a set of classes to easily generate any XML structure defined in IDP, and conversely to extract any information contained within. • This is achieved by employing an Open Source software tool called Java Architecture for XML Binding (JAXB): • offline: to generate the classes to handle XML • at runtime: to • Un-marshal XML structures to Java objects (the instances of the classes generated from the schemas). • Marshal Java objects into XML structures. • Verify if the incoming xml document is valid or not according to the schemas

26. The Package classes • The Core library provides a set of functions to • bundle media resources with the DCI and other information in a file named DCF • extract this information from a DCF. • The DMP Content Format is based on the MPEG-21 File Format. • The Package classes allow any Java application to access the information contained in a DCF or to create a DCF based on data in input.

27. The Protocols classes • Devices in a media Value Chain require a standard protocol to communicate. • The description of the various protocols is done in WSDL. • The Core library provides a set of functionalities to generate and parse the XML messages exchanged between devices while performing a Protocol • The Open Source Axis tool is used to send and receive such messages over the SOAP protocol

28. Part 3 The Chillout Auxiliary Library

29. What is the Auxiliary Library • It comprises of those classes encapsulating the functionalities of a number of modules required for devices to operate according to the IDP specification. • Commercial applications may well decide to implement those key DRM components in a proprietary way, even in hardware. • Chillout at this stage only provides a reference implementation of them.

30. Auxiliary Library Components • The Security Manager: • a module incorporating all those functionalities such as securely storing digital certificates and licences, performing operations involving Digital Signatures, etc... • The DRM Processor: • a SAV module in charge of instantiating and managing the DRM Tools protecting a media resource • DRM Tools: • modules performing DRM functions such as decryption, key management, etc.

31. Auxiliary Library Components

32. Part 4 The Chillout Application / Devices

33. Devices overview • Chillout provides a set of devices that are easy to configure and run. • This helps promoting adoption of Chillout and the DMP specification by enabling those users • not experienced in the DRM field • not enough skilled in programming • working for small companies to experiment with a technology that so far could only be used by those experts in the field. • The Applications category contains source and executable Java code built on top of the Core classes, and integrated with Auxiliary classes.

41. Chillout vs. AD#7 • Chillout: an OSS implementation of the DMP IDP specification, managed by an active open source community dedicated to foster adoption of interoperable DRM. • DMP Chillout itself can create an open and fair security infrastructure that can be employed for a variety of uses. • By mapping the evolving Chillout to a fixed Reference Software shell, Fixed DMP AD#7 can assist various DMP implementation in a active manner
