New Features Added To Leader’s IP Analyzer

Leader Electronics announces new additions to the capabilities of its LVB440 IP analyzer.

Designed to monitor and analyze high-bitrate media traffic in broadcast production studios, OB vehicles, master control facilities and transmission networks, the Leader LVB440 allows analysis of SD, HD, UHD and 4K data flow over media networks of any size. Housed in a compact 1U chassis, it gives production teams the resources needed to perform real-time checks on large numbers of streams and multiple resolutions in parallel at multiple locations. Operators gain the ability to survey every media transport layer of an IP network simultaneously, allowing issues to be rectified before they impact the quality of service experienced by television viewers. Controlled via an HTML-5 web browser, the LVB440 can be operated by up to eight local or remote users. Data rates of 10, 25, 40 and 50 gigabit/s are supported, extending up to 100 gigabit/s via dual interfaces.

Four new features are now available as standard, and existing models can be updated online to the latest version:

  1. LVB440-SER22 - JPEG XS SMPTE ST.2110-22 compression analysis.  JPEG XS provides a similar compression level to the JPEG 2000 standard, with lossless compression of between 10 and 15 times the original but much lower latency, thus allowing for responsive real-time broadcast production.
  2. Closed captioning measurement.  Closed captioning is a process of displaying text with a broadcast television feed to provide additional or interpretive information. The LVB440 now supports OP-47, CEA-608 and CEA-708 data analysis, including on-screen display and technical debugging.
  3. Support for 7.1 surround sound, 5.1 surround sound and mix-down to stereo pair.  This feature adds 5.1 and 7.1 multichannel surround sound display capability plus LUFS (Loudness Unit Full Scale) monitoring mix-down to stereo pair for remote monitoring via a web-browser.
  4. Rolling packet capture measurement.  This mode supports continuous capture of data packets in a loop mode, simplifying faulting-finding if an error is detected.
