Introduction
Many developing countries are in the process of deploying fibre optics, therefore deployment of digital television (TV) over fibre optics is envisaged. Digital TV signals carried over fibre optics would conform to Recommendations [ITU-T J.185], [ITU-T-J.186], [ITU-T J.83], [ITU-T J.382], among others, but the proper selection of Recommendations is essential to meet the requirements of each country.
