Project description

MediaMòbil Project was developed in cooperation with three important Catalan universities: Universitat Politècnica de Catalunya (UPC), Universitat Pompeu Fabra (UPF) and Universitat Ramon Llull (URL) together with some companies like Cromosoma and Tempos21. Its aim was to investigate about the mobile technologies needed to develop advanced multimedia applications in the mobile area. Several tools and modules were implemented; being a multi-player game over mobile using GPS localisation features the final demonstrator.

DMAG activity

Our work consisted in the implementation of a mobile DRM solution that selects and combines different mechanisms from both MPEG 21 and OMA DRM, making the necessary adaptations in order to be able to provide a functional solution for the mobile environment. In particular, the following elements from both standards were used:

  • OMA DRM REL licenses
  • An adaptation of the MPEG 21 REL (Rights Expression Language) Authorisation algorithm
  • A simplification of the MPEG 21 ER (Event Reporting) mechanism for being used by the mobile
