Digital Video Channel Elimination and Insertion System

Part Number:
DVISm Digital Video Insertion System

, ,


The DVISm Mini encoder/multiplexer with RF output is an optimized all-in-one solution for inserting security cameras and locally generated content into an MDU, hotel or commercial property in digital format. The hardened, cabinet style form factor, scalable MPEG-2/H.264 HD/ SD encoder cards, demod card and integrated channel deletion filter allows the DVISm device to be tailored to any insertion methodology. The optical transmitter module enables insertion functionality into various FTTx architectures.


  • Dynamic PID monitoring engine prevents outages of pass through and inserted programs due to PSI changes introduced by DAC/DNCS or EdgeQAMs
  • “One-click” configuration download and upload for fast and easy bulk configuration management
  • Enhanced graphical interface includes step-by-step feedback during QAM tuning process
  • RF bypass switch bypasses deletion filter and restores original QAM in case of power failure or unit reboot
  • Cost-effectively insert locally generated MDU content (e.g. security camera or localized advertising) in digital format (MPEG-2/H.264, SD/HD, QAM/IP)
  • Ideal for spectrum reclamation or MDUs provisioned with digital-only set-top boxes (DTAs)
  • Scalable wall mount solution: up to 6 SD (or 3 HD) programs can be multiplexed onto a QAM channel
  • Satisfy any digital insertion methodology: blank QAM from headend, locally deleted QAM at MDU, and underutilized QAM (add/drop) from headend – see functional application diagram
  • Integrated QAM channel deletion filter (filter is optional)
  • Fully integrated audio/video encoders, demodulator, multiplexer and QAM modulator/RF upconverter
  • Hot-swappable 1 and 2-channel encoder cards, QAM demodulator card and IP output card
  • Possibility of mixing HD and SD encoder cards within the same chassis
  • Allows users to deliver up to 6 SD (or 3 HD) baseband A/V inputs (e.g. security camera or local content) via multiplexed MPEG-2/H.264/QAM to the MDU in a cost-effective and efficient manner; field-scalable with plug-in 1 or 2-channel encoder cards
  • HTTP-based GUI allows for easy set-up and control without the need for proprietary software installation
  • Remote access and SNMP monitoring available via integrated RJ45 Ethernet interface
  • MDU hardened wall mount enclosure with lockable front door
  • Very flexible and easy expandable – all features are in one box with front access to all modules and connections
  • Includes the following operational modes (set through GUI): IP output only, IP+QAM output simultaneously, and QAM output only (please see appropriate data sheet for IP/QAM specs)
