Leader Electronics announces additions to the feature set of the LVB440 IP Analyzer. The instrument’s IP traffic and signal monitoring resources are now supplemented by signal generation tools plus the ability to monitor and analyze “SR Live Metadata”. This enhancement adds support for JPEG XS ST 2110-22 compression analysis, closed captioning measurement, 7.1 and 5.1 surround sound, and loop-mode continuous capture of data packets.
Operators can create placeholder reference signals locally using the integral GUI or remotely via NMOS. SDR and HDR signals such as chroma bars can be configured for specific video resolutions or refresh rates, including a user-definable video or audio ident, saving time during system setup or alteration. Placeholders can also be created to represent video and audio sources that will be needed later in the production timeline. Network connections, such as remote OB or studio sources, can be tested prior to the start of a live broadcast.
Leader added support for “SR Live Metadata” decoding and display to its ZEN series waveform monitors and rasterizers in Q4 2019 and is now extending this capability to the LVB440 for use in IP network evaluation. “SR Live for HDR” [Reference 2] forms part of the broadcast production workflow when content is transcoded from 4K HDR or HD HDR. Using metadata sourced from each camera, the LVB440 enables production staff to identify and correct potential issues quickly and effectively.
The LVB440 is controlled through an HTML-5 browser and provides full support for up to eight local or remote users. It offers production teams the ability to perform real-time checks of streams at various resolutions across multiple locations.
When connected to primary and secondary networks, the LVB440 can monitor and analyze redundancy within the SMTPE ST 2022-7 standard, which is used to ensure seamless protection switching. Tools are also provided for PTP clock analysis, including clock source detection, timing accuracy and individual flow path latency. SMPTE ST 2110, ST 2022-6 and ST 2059-2 PTP standards are also supported, as well as open networked media specifications.
