SmartGate ATSC

ATSC 3.0 Broadcast Gateway - ATSC3.0 Scheduler

Software based & virtualized broadcast gateway to deliver any Linear & NRT contents over ATSC 3.0 network.

Applications

  • Linear & NRT contents delivery
  • Network synchronization & SFN broadcasting
  • QoS class scenario with multiple PLP

Highlights

Mastering the ATSC3.0 signaling

SmartGate is able to interface with an unlimited number of ATSC3.0 signaling servers & packagers, and manages automatically the ATSC3.0 signaling from the different LLS (Low Layer Signaling), including the automatic generation and delivery of the SLT (Service List Table) to ensure the exact description of the on-air services.

Managing all types of modulation

SmartGate supports all ATSC 3.0 modulation profiles - all modulation’s capabilities - from simple subframe and single PLP, to multiple subframe and multiple PLPs, including the advanced management of LDM (Layer Division Multiplex) to ensure the Single Frequency Network implementation. It allows Broadcasters to have the entire possibility to choose its signal coverage and robustness, targeting simultaneously multiple receivers’ capabilities within one RF channel; offering different business
models for a network.

Virtualized & scalable

By moving the legacy ATSCheduler hardware based platform towards a new software based & virtualized appliance (SmartGate), ENENSYS enable broadcasters to install & manage their ATSC3.0 Core Network infrastructure directly into a public or private cloud and then to win in scalability, enhance the ATSC3.0 Core Network speedy recovery time and save cost & spaces.

Secured & Innovative

ENENSYS has developed a patented technology ensuring a seamless 1+1 redundancy of 2 ATSC 3.0 SmartGate broadcast gateways providing the capability to switch from main to backup unit without any perturbation at the transmitter site – no desynchronization - even in SFN mode.
