One of the essential benefits of networks is a supporting of convergences such as the fixed mobile convergence (called FMC) and telecom-broadcasting converged services like the IPTV especially in the ITU-T Y.2000 series of Recommendations. This Supplement to the ITU-T Y.2000-series Recommendations on the scope of N-Screen service scenarios for the FMC provides various cases of N-Screen service scenarios. This Supplement uses the features defined in Y.2720 sup.14, Y.sof (Supplementary service scenarios for fixed-mobile convergence).
