Digital Radio Mondiale (drm)
The DRM system, and the primary audio coding used, have been described in previous articles of EBU Technical Review [2][3]. The system specification has been published by both ETSI {TS 101 980 V1.1.1 (200109)} and the IEC (PAS 62272-1) and is the subject of an ITU recommendation, BS1514. There is also a new draft ITU recommendation, BS1514-1, which includes minimum signal strength and protectio...
متن کاملIndirect DRM Evaluation Architecture
In this paper we consider some of the basic design principles that should support the development of future DRM systems. We begin by discussing some of the problems associated with current DRM environments, and how they might be alleviated through the adoption of an open architectural framework based on basic design principles. We then demonstrate a particular implementation referred to as the ...
متن کاملDistributed DRM System
There is no standardised framework for digital rights management (DRM). With the proliferation of DRM systems, there is an increasing need for portability across multiple platforms and DRM systems. Current DRM systems can also be considered incomplete. Some DRM systems are not scalable enough; some are too focused on a particular application/file format and most do not have adequate mechanisms ...
متن کاملAlternative DRM formulations
In this paper, we present two DRM formulations. For a pseudo–Poisson equation, if the right hand side is a linear operation on the dependent variable, we can derive a new DRM formulation. In comparison with the traditional DRM formulation for the same equation, the new one is much easier and more efficient. For the axisymmetric Poisson equation, we construct a DRM formalation by using the linea...
متن کاملPartitioning of a DRM Receiver
In this article we present the results of partitioning the OFDM baseband processing of a DRM receiver into smaller independent processes. Furthermore, we give a short introduction into the relevant parts of the DRM standard. Based on the number of multiplications and additions we can map individual processes on a heterogeneous multi-tile architecture. This architecture can meet both the computa...
