IP and Broadcasting Systems Convergence

Radio Broadcasting

The AM Signalling System (AMSS), now a published ETSI standard [2], has been designed within the DRM Coding and Multiplexing (DRM-CM) group. It uses low bitrate phase modulation of the AM carrier to add a small amount of digital information to existing analogue AM broadcasts on short-, mediumand long-wave, giving similar functionality to that provided by the Radio Data System (RDS) on the FM ba...

Joint Resource Management of Cellular and Broadcasting Systems - Research Challenges

One of the ways towards provision of low-cost mobile multimedia entertainment is to make possible the sharing of the wireless resources among multiple operators of different radio access technologies. Here we discuss opportunities for new system architectures enabled by sharing the resources belonging to the cellular and broadcasting systems, namely the spectrum and the infrastructure. The goal...

Observables for Mobile and Wireless Broadcasting Systems

We discuss the presence of localities in observables for process calculi for mobile and wireless broadcasting systems in the context of weak barbed congruences and demonstrate that observability of the locality of a broadcasting node may be unsuitable when abstracting from node mobility, a natural abstraction current calculi agree upon. The discussion is carried out through a calculus bAπ, a co...

Data Hiding Scheme for Amplitude Modulation Radio Broadcasting Systems

This paper proposes a data hiding scheme for amplitude-modulation (AM) radio broadcasting systems. The method of digital audio watermarking based on cochlear delay (CD) that we previously proposed is employed in this scheme to construct a datahiding scheme in the AM domain. We investigate the feasibility of applying the method of CD-based inaudible watermarking to send inaudible additional mess...
