Leader Launches LVB440 High Bit-Rate IP Packet Monitor
Leader Electronics announces a new addition to its range of video and audio test equipment. The LVB440 IP Analyzer allows efficient analysis of SD, HD, HD HDR, 4K and 4K HDR data flow over media networks of any size.
 
Designed to monitor and analyse high-bitrate media traffic in broadcast production studios, OB vehicles, master control facilities and transmission networks, the analyzer supports data rates of 10, 25, 40 and 50 gigabit/s, extending up to 100 gigabit/s via dual interfaces. The core processor is more than capable of handling the 48 gigabit/s data rate required for full bandwidth source 8K.
 
Housed in a compact 1 U chassis, the LVB440 is controlled via an HTML-5 web browser and provides full support for up to eight local or remote users. 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 program viewers.
 
When connected to primary and secondary networks, the LVB440 can monitor and analyse redundancy within the SMTPE ST 2022-7 standard which is used to ensure seamless protection switching. Tools are also provided for Precision Time Protocol 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 as well as Networked Media Open Specifications are also supported.
Intuitive packet display analytics including single or multiple stream correlation allow operators to identify errors quickly and easily. Media metadata and deep packet analytics can be displayed. Also provided are traditional colorimetry measurement tools, including a vectorscope with ITU Rec. 601, 709 and 2020 compatibility for checking chroma saturation issues that can arise in mixed standard and HDR environments.
 
A flow-overview function allows any data flow or signal stream on a network to be bonded into a single viewing configuration comprising video, audio and ancillary data. This combination can then be stored as a preset for later recallUp to eight stereo-pair audio channels can be metered and monitored. The AES67 standard for audio over IP and audio over Ethernet interoperability is supported. 
 
Included as standard with the LVB440 is the Widglets API HTML5 video monitor which allows the LVB440 to be deployed for wider applications. Waveforms from multiple cameras can be supervised via a single HTML5 video monitor view. The resultant data can be shared by production team members co-operating across multiple locations.
 
Available as an option, the Instrument View Engine allows a user's 11 inch Apple iPad Pro mobile workstation to be deployed as a colour-accurate touch panel. The kit provides advanced analytics, making the LVB440 easy to use in any production environment.
