Description

GigaCaster video gateways provide a cost effective, versatile and efficient solution for delivering digital TV content over IP networks.

ENENSYS’ video over IP gateway is suitable for delivering over IP networks any MPEG content from one point to another point (contribution) or from one point to multi-point (distribution).

GigaCaster high density video gateways can handle the carriage of up to 8 MPEG-2 Transport Streams (MPEG-2 TS) in ASI to IP direction or in IP to ASI direction. Each MPEG-2 TS can include either MPEG-2 or MPEG-4 (H264) video content in SD or HD format.

When broadcasting over Single Frequency Network, ENENSYS has implemented a patented technology that copes with any IP network issues and guarantees a reliable SFN broadcasting without external 10MHz reference.

Applications:

  • Point-to-point video delivery
  • Deliver any MPEG content from satellite, cable source
  • Transmission sites interconnections
  • Reliable SFN broadcasting over IP
  • Radio Link sites interconnections

Benefits:

  • Front panel : Ease operation and maintenance
  • Versatile : ASI>IP or IP>ASI
  • Multi-standard : ATSC, DVB-T/H, ISDB-T
  • Video agnostic : MPEG-2 or MPEG-4/H.264
  • Scalable : From 1 ASI port up to 8 ASI ports
  • Unique patented SFN preservation
  • High throughput : Up to 100Mb/s per ASI
  • Reliable : Hardware based for 24/7 operation

Characteristics:

  • Up to 8 DVB-ASI ports
  • Gigabit ethernet port for IP distribution
  • Optional SFP port for Fiber optic distribution
  • RTP / UDP support
  • Unicast and multicast support
  • DVB-IPI FEC compliant
  • Pro MPEG Forum CoP#3 / SMPTE 2022
  • Clock & drift correction
  • Network jitter removal
  • IGMP v2/v3 support
  • Full SNMP v2 support
  • Real-time monitoring
  • Fault relay alarm
