"state-of-the-art direct-to-tower SFN distribution platform"

use cases with significant satellite bandwidth savings:


    platform enables parallel DTT & DTH by single transmission
    inexpensive entry of satellite DTH operators into terrestrial Digital TV networks
    DVB-T2 (MI) & ISDB-BTS:

    • DTT - direct to TV transmitters
    • DTH - satellite home users
      what presents entire satellite capacity savings for DTH service
    • generates SFN adapted TV signal from DTH broadcasting at TV transmitters


    enables "insertion of regional advertisements into national TV" at TV tower
    enables single transmission for national TV channel with multiple regional advertisements, efficient insertion of regional advertisements into national TVs


    platform enables single transmission of national TVs present in multiple regional broadcasts.
