Abstract
For some years the BBC and other European broadcasters have been investigating systems for broadcasting radiodata labels from v.h.f. radio-broadcast transmitters. These data signals are primarily intended to aid radio listeners in tuning their receivers to a desired station orprogramme. Other applications, such as the transmission of simple messages, are also envisaged. Although no firm specification for radio-data has yet been agreed by European broadcasters, recent international field-trials of various proposed radio-data systems were a significant milestone in the development of a standardized radio-data system. These field-trials also confirmed that reliable radio-data reception is possible with low-cost receiver/decoders even under very adverse reception conditions.
