  5. 4. IP Multicasting over DVB-T/H and eMBMS : Efficient System Spectral Efficiency Schemes for Wireless TV Distributions

    Master-uppsats, Institutionen för informationsteknologi och medier

    Författare :S.M. Hasibur Rahman; [2012]
    Nyckelord :eMBMS; DVB-T; Multicasting; system spectral efficiency;

    Sammanfattning : In today’s DVB-T/H (Digital Video Broadcasting-Terrestrial/Handheld) systems, broadcasting is employed, meaning that TV programs are sent over all transmitters, also where there are no viewers. This is inefficient utilization of spectrum and transmitter equipment. IP multicasting is increasingly used for IP-TV over fixed broadband access. LÄS MER
