Abstract

A communications system is provided in which code word pairs are distributed within the audio of a television or radio programme (or the like). Each pair of code words includes an ID code word that is the same for a given programme and a synchronisation code word that is unique within the programme. A portable user device is able to synchronise itself to the programme using the embedded synchronisation code words.
