ASI Input Module for DQMx ASI Input Module for DQMx

DQMx (Digital QAM Multiplexer) accepts up to four inputs in ASI, 8VSB, and QAM formats, and delivers one output in QAM format in the 54-864 MHz range. Two types of input modules are available (ASI and 8VSB/QAM), and any combination of input modules is allowed – for example, DQMx can be equipped with 2 ASI and 2 8VSB/QAM input modules. Each ASI input module can process up to twelve channels, not to exceed 270 Mbps. Each 8VSB/QAM input module can process up to twelve channels, not to exceed 19.4 Mbps for 8VSB or 38.8 Mbps for QAM 256. The QAM-modulated output can contain up to twelve channels, not to exceed 38.8 Mpbs when operating in QAM 256 mode.

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.

FEATURES AND BENEFITS

  • Accepts up to 12 unencrypted MPEG-2/H.264 Single or Multi-Program Transport Streams (SPTS or MPTS) in ASI format, each up to 270 Mbps
  • Provides 1, 2, 3, or 4 MPTS output streams when operating in Single, Dual, Triple, or Quad IP Outputs Modes respectively
  • Provides comprehensive GUI-based monitoring and control via standard Web Browsers
  • Performs PCR (Program Clock Reference) correction, null packet insertion, and deletion
  • Supports EAS (Emergency Alert System) input on ASI Input port 12
  • Supports Uni- and Multi-cast thru RTP/UDP protocols
  • Supports ARP, IGMPv2, and ICMP protocols
  • Supports user-defined PSIP configuration

Each ASI input module can process up to twelve channels, not to exceed 270 Mbps. Each 8VSB/QAM input module can process up to twelve channels, not to exceed 19.4 Mbps for 8VSB or 38.8 Mbps for QAM 256. The QAM-modulated output can contain up to twelve channels, not to exceed 38.8 Mpbs when operating in QAM 256 mode.

    FEATURES AND BENEFITS

  • Maintains MPEG-2 mapping if the input ASI stream is removed and the same stream is added later (for example, after a power cycle)
  • In addition to PAT, PMT, and MGT tables, supports the RRT, STT, and VCT tables of the MPEG-2 transport stream
  • Automatically re-maps duplicate PIDs, program numbers, and minor channel numbers
  • Maintains mapping with new PAT/PMT/MGT versions and same programming
