The increase of digital media formats fostered the creation of interactive multimedia applications, including the development of multi-user interactive scenarios. There are many spaces where digital interactive multimedia artifacts are consumed by groups of people, such as homes with Digital TV, theaters with Digital Cinema and conferences with interactive lecture presentations. In this thesis, a platform to support the execution of distributed hypermedia applications is proposed aiming at these spaces of collective digital multimedia consumption. The proposed platform uses the NCL language as the application description format, since it is a hypermedia glue-language that supports the concept of multi-device applications following a declarative abstraction level. The platform establishes a reference software architecture, defining mechanisms and interfaces for heterogeneous device integration. A prototype is implemented and validated against different usage scenarios, in which hypermedia applications use media resources coming from and going to multiple devices.
