SmartGate ATSC

ATSC 3.0 Broadcast Gateway

SmartGate ATSC is the new ENENSYS Broadcast Gateway
for ATSC 3.0 delivery, fully virtualized and providing IP
stream adaption, PLP (Physical Layer Pipe) allocation,
SFN timing, in-band control and signaling to all the
modulators in the ATSC3.0 network.

Applications

  • Synchronization of ATSC3.0 modulators for SFN broadcasting

  • Automatic configuration of ATSC3.0 exiters

  • Provides service-specific robustness thanks to Multi-Physical Layer Pipes (PLP) and Multi Sub-Frame management:

    • Mobile broadcasting
    • SD, HD and 4K Broadcasting

 

Highlights

Managing all types of modulation

Using Multiple Sub-Frames and/or Multiple PLP (Physical Layer Pipes) provides service-specific robustness according to the delivered services.

1+1 seamless redundancy

1+1 redundancy mechanism that guarantees a seamless switch-over in SFN and MFN to avoid any TV black-out during switch-over operation between 1+1 redundant redundant SmartGate or STL TP delivery network.

SFN Management

SmartGate enables SFN broadcasting over ATSC3.0. It provides the timing signaling information to all modulators to generate the same data at the very same time over the same frequency.

Software based & virtualized

SmartGate ATSC enables broadcasters to install & manage their ATSC 3.0 Core Network infrastructure directly into a public, private or hybrid (on premises) cloud and then to win in scalability, enhance the ATSC3.0 Core Network speedy recovery time and save cost & spaces.
