Probium QAM

Affordable yet comprehensive device for remote 24/7 full ETR 290 monitoring and error logging of QAM channels.  Decodes and monitors RF parameters and ETR 290 compatibility and errors in MPEG transport streams (PAT, PMT, NIT, SDT, CAT, TDT, and TOT).  With its powerful carrier search engine, it is able to find and analyze all available RF channels.  Detects missing audio or video streams.  Measures and reports via email the essential parameters of both RF and digital signals at an exceptional price/quality ratio.  RF coax input.

Professional Sixteen Channel Linux® Based Encrypted or Digital Clear QAM to IP Gateway that Integrates Our PC Bus Based QAM RF Receivers and De-encapsulates and Routes Selected or All Transport Streams to Any MAC Address via IP. Can Work as a Low Cost “Front End” in Small VOD Implementations. Typically the Desired Streams are Streamed in Real Time using UDP, RTP, or HTTP, via IP Multicast or Unicast Streams to IP Set Top Boxes (STB's), Video Servers, or Designated VLC or JW Player Equipped PC Clients for Viewing.
