IP<>ASI Transcoder IP<>ASI Transcoder

IPAT (IP ASI Transcoder) is a bi-direction IP ASI transcoder that accepts MPEG2/4-encoded input streams in 1000Base-T Ethernet (GbE) and ASI formats simultaneously. GbE input is transcoded to ASI output while ASI input is transcoded to GbE output.

FEATURES AND BENEFITS
ASI Input/Output interface

  • Supports Single or Multi Protocol Transport Services (SPTS or MPTS)
  • Performs PCR (Program Clock Reference) correction
  • Allows Null Packet insertion & deletionGbE Input/Output interface
  • Provides robust protection against IP network jitter and delay
  • Performs PCR (Program Clock Reference) replacement
  • Supports Uni- and Multi-cast thru RTP/UDP protocols
  • Supports IPv4, ARP, IGMPv2, and ICMP protocols
  • Supports variable and constant bitratesOptional RF modules
  • RF IN/OUT modules support both 8VSB and Annex A/B QAM modes
  • RF IN module accepts 8VSB free-to-air & NTSC CATV standard channels 2-135
  • RF OUT module provides NTSC CATV standard/sub-band channels 2-135/T7-T14
  • RF OUT module provides output level of +40 dBmV

    12:1 ASI-to-IP Multiplexer 12:1 ASI-to-IP Multiplexer

    MUX-12A-IP (12:4 ASI-to-IP Multiplexer; 12xASI > 4xIP) is designed for cherry-picking applications, allowing operators to create custom-made channel lineups by grooming standard-definition (SD) and high-definition (HD) programs on an as-needed basis. The multiplexer accepts up to twelve (12) unencrypted MPEG-2/H.264 inputs in ASI format and multiplexes them into up to four (4) MPEG-2/H.264 Multi-Program Transport Streams (MPTS) which are then encapsulated and assigned to up to four (4) IPv4 addresses in 1000Base-T Ethernet (GigE) format suitable for distribution over Cat-5 networks. Any two (2) of the four (4) MPTS output streams are also available in ASI format. Each ASI input stream can contain up to 20 unencrypted programs, for a total of 240 input programs. The GigE output can contain up to 20 programs groomed in up to four (4) MPTS output streams from any of the available 240 input programs, each MPTS output stream not to exceed 214 Mbps, and the sum of programs in all MPTS output streams not to exceed 20. The multiplexer is EAS-compliant (Emergency Alert System) – operator can assign ASI port #12 as an EAS input which, when activated, will override the content of all other ASI inputs. Comprehensive remote monitoring and control is accomplished via a GUI-based interface using any standard web browser.
