A Viable Passive Optical Network Design for Ultrahigh Definition TV Distribution

Advances in OptoElectronics, Volume 2013, Issue 1, 2013., 2013
International Telecommunication Union (ITU) has recently standardized ultrahigh definition television (UHD‐TV) with a resolution 16 times more than the current high definition TV. An increase in the efficiency of video source coding or in the capacity of transmission channels will be needed to deliver such programs by passive optical network (PON).
