AN ANALYTICAL APPROACH TO ANALOGUE-DIGITAL TRANSITION IN RADIO AND TELEVISION BROADCASTING
The International Telecommunication Union (ITU) has directed some countries of the world to migrate from analogue to digital broadcasting service before June 17, 2015. This transition has many challenges which have been approached in many ad hoc ways by several countries. This study is aimed at formulating a model that could measure the degree of success of the digital transition programme at any stage of the process. It uses control engineering approach, particularly the state variable analysis, to direct the preparation and implementation of the transition exercise. Success factors which include: teamwork across the value chain (T), strong leadership (L(t)), effective communication strategy (C) and sufficient financial resources for the transition (R), are identified as the key parameters of the transition. The result from the model simulation shows that the degrees of success of the transition programme when the inputs are bad, poor, fair, good and excellent are 18.40%, 36.80%, 55.2%, 73.60% and 92.00% respectively. The study is significant in that it develops a model that could measure the degrees of success of the programme, when the success factors (inputs) and the initial conditions (ıı), are known. A model for sustainability of digital radio and television broadcasting is left for future research.
