Service Following allows cross-referencing to other modes of reception of the same programme, such as AM, FM, and other DAB ensembles. Receivers allowing this function will automatically switch to other modes of reception if the current one becomes unavailable (e.g. when leaving the coverage area).
Guidelines for Service Following were seen to be outdated by the WorldDMB Technical Committee. As a result a task force headed by Klaus Probst, SRG SSR was set up to oversee the process of compiling a new document of recommended rules for correct operation. Other representatives involved in the task force were Arqiva, Audi, BBC, Bosch, Continental, Fraunhofer, Frontier Silicon, Global Radio, IRT, J&K Car Electronics, and PURE.
This document aimed to give a better definition of what is mandatory, what is optional, what broadcasters must do and also what receivers must do, and was based on real cases submitted by the members of the Technical Committee.
A draft document redefining these parameters was approved during the February Technical Committee meeting. Subject to the approval of the WorldDMB Steering
