Yui Inoue, Takeshi Maruyama, Junichi Katayama, Seiya Funaoka

The Fiber To The Home (FTTH) communication system for CATV, using the Passive Optical Net-work (PON) system, can allow an efficient network. In addition, the IP broadcasting system is provided over managed networks and ensures the same quality as the conventional Radio Frequency (RF) system, thus enabling service provision with minimal picture degradation and delay even when many people simultaneously view real-time broadcasting content. In order to make an IP broadcasting system practical, we will introduce supports for the PON system, methods which enable to objectively evaluate that the system meets the quality specified in the technical standards, and the initiatives to improve the efficiency of the system.
