Now, in addition to growing interest in improved sound quality for broadcasting services, an ever increasing number of broadcasting services are being demanded and provided (public and private), and this in turn is leading to increased congestion of the existing broadcasting frequency bands (and thus diminished programme quality). These problems are compounded under mobile reception conditions, for which the VHF/FM was never designed or planned for.

The allocation of new frequency bands is a very difficult and time-consuming goal to achieve. Digital transmission techniques, which, when suitably applied, can lead to a more efficient utilisation of the frequency spectrum, provide a means of r
