This paper presents the 1ST RELY project which aims at Integrating Satellite Digital Radio Broadcasting (S-DB), terrestrial cellular technology and EGNOS satellite navigation

This document reports on a carefully designed set of fixed and mobile reception tests in Mexico City on the DRM (Digital Radio Mondiale) system at a frequency in the uppermost shortwave broadcasting band – around 26 MHz – for local broadcasting. The testing was done during July 2005. These were not operational tests; that is, neither the transmitter antenna, nor antenna location, nor transmitte...

Wireless communication is used in many different situations such as mobile telephony, radio and TV broadcasting, satellite communication, and military operations. For all these situations, a frequency assignment problem arises with application of specific characteristics. Different modelling ideas for every problem features, have been developed such as the handling of interference among radio s...

We consider the problems of deterministic broadcasting and gossiping in completely unknown ad-hoc radio networks. We assume that nothing is known to the nodes about the topology or even the size of the network, n, except that n > 1. Protocols for vanilla model, when n is known, may be run for increasingly larger estimates 2 on the size of the network, but one cannot determine when such a protoc...

Examining QoS at the end-user level for multimedia broadcasting systems often reveals weaknesses at the specifications of the systems that degrade the overall performance, and of course the satisfaction level of the user of the services. It is the scope of this paper to examine the characteristics of Eureka’s DAB system at the services level, and present some extensions to this system that have...

PB Core is the result of the public broadcasting metadata initiative (PBMI). It is an effort of the public radio and television broadcasters to develop a schema for the description of their assets. PBMI is under the auspices of the Corporation for Public Broadcasting. The paper discusses the user-centered development of the schema, the elements of the PB Core, the application profile, and the f...
