  • MPEG-2 Program Stream real time decoding at an aggregate bandwidth of 160Mbps
  • Higher aggregate bandwidth can be achieved by adding expansion modules
  • Variable bit rate MPEG-2 decoding supported
  • Decodes at both D1, half D1, SIF and CCIR-601 resolutions
  • Both NTSC and PAL are supported in the same machine
  • 8 to 36 streams in a single low profile small footprint chassis
  • Industrial grade chassis
  • High MTBF Ultra SCSI hard drives to store digital content
  • Optional hot swappable drive array
  • Optional patent pending software RAID module
  • Closed captioning on each channel
  • 3:2 Pulldown for film rate support
  • Automatic playback based on a pre-defined schedule
  • Full range of networking and expansion options
  • Allows remote system management
