Leader Demonstrate Latest Advances In SDI and IP Test & Measurement At IBC 2022

Since the previous IBC show in 2019, Leader has added an IP-specific product to its range of test and measurement products: the LVB440 IP Analyzer. The company now offers a complete IP solution ranging from the LT4610 and LT4611 PTP generators through the ZEN Series LV5600 and LV7600 True Hybrid IP and SDI test and measurement instruments to the LVB440.

Leader's ZEN Series waveform monitors and rasterizers are widely used by studios, OB service-providers and postproduction facilities creating 4096 x 2160 pixel 4K DCI content for cinematic and streaming releases rather than 3840 x 2160 resolution UHD. The ZEN Series supports both formats so provides maximum freedom to transition between the two publishing standards. This is becoming increasingly important given the growing use of 4K DCI by online TV channels.

Making its IBC show debut, Leader's LVB440 IP Analyzer allows the analysis of SD, HD, HD HDR, 4K and 4K HDR data flow over media networks of any size. The LVB440 offers familiar visualization tools such as waveform monitoring, vectorscope, picture monitoring, allowing broadcast and production crews to manage real-time analysis and troubleshooting of IP-based network audio and video streams. Packet analysis of uncompressed video and audio is available with microsecond accuracy. Up to eight clients can view the analysis data in a standard web browser at the same time for simplified remote operation.

The latest version of the LVB440 incorporates new signal generation tools plus a customisable quad-split test and measurement display, featuring, waveform, vectorscope, picture and audio monitoring. Also making its IBC debut is the LVB440's ability to monitor and analyze Sony SR Live Metadata. SR Live Metadata can be embedded in SDI signals, MXF files, and IP networks, and by combining with compatible products, it is possible to prevent setting mistakes during conversion and simplify operations.

Additional LVB440 tools making their first IBC appearance include 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 feeds that will be required later in the production timeline. Network connections such as remote OB or studio sources can then be tested before the start of a live transmission.
