Leader deploys new features for LVB440 IP analyzer

Leader Electronics has announced new additions to the capabilities of its LVB440 IP Analyzer.

Designed to monitor and analyze high-speed multimedia traffic in broadcast production studios, reporting vehicles, main control facilities and transmission networks, the Leader LVB440 enables analysis of SD, HD, data streams, UHD and 4K over media networks of any size. Housed in a compact 1U chassis, it gives production teams the resources to perform real-time checks on a large number of streams and multiple resolutions in parallel across multiple locations. Operators have the ability to simultaneously study each media transport layer of an IP network, allowing problems to be rectified before they affect the quality of service seen by viewers. The LVB440 is controlled through an HTML-5 web browser and can be used 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 through dual interfaces.

Four new features are now available as standard. Existing models can be updated online to the latest version:

Compression analysis LVB440-SER22 – JPEG XS SMPTE ST.2110-22
JPEG XS offers a similar level of compression to the JPEG 2000 standard, with lossless compression between 10 and 15 times the original latency but much lower, allowing responsive real-time broadcast production. This makes the standard particularly useful when bandwidth is limited within a production network or when there is a lack of control over the timing accuracy that can be achieved between the leader and follower PTP clocks in long networks. distance between the studio and the place. The ability of JPEG XS to work over both PTP and traditional transport streams makes it a very flexible compression standard. This is fundamental to delivering content in an efficient and affordable manner, while ensuring high image quality. Essentially, JPEG XS allows broadcast networks to do more with less.

The encoding process itself introduces less than a millisecond of latency, unlike the 60ms typically associated with JPEG 2000. 60ms may seem short, but streaming video as part of a workflow adds up. quickly to a latency that control room personnel find excessive. JPEG XS promises to enable responsive and natural production. This was made possible by the extension of SMPTE ST 2110 to the ST 2110-22 standard for transporting compressed video. JPEG XS requires less CPU processing than most other algorithms.

The integration of JPEG XS compression analysis makes the LVB440 ideal for broadcast networks, production studios, main control facilities, OB vans and public places. The already large capabilities of the LVB440, supporting data rates up to 100 Gbps and therefore 4K output, gives broadcasters the flexibility to monitor complex and varied network configurations that consist of both IP elements and inherited. In this way, they can ensure reliable and high quality of service from anywhere in the world just by accessing the probe through an HTML-5 browser.

Closed caption measurement
Closed captioning is a process of displaying text with a television stream being broadcast to provide additional or interpretive information. It usually consists of a transcription of the audio portion of a program or an alternative translation of a primary audio language. The LVB440 now supports OP-47, CEA-608, and CEA-708 data analysis, including on-screen display and technical debugging.

Support for 7.1 surround sound, 5.1 surround sound and downmix to stereo pair
This feature adds 5.1 and 7.1 multichannel surround sound display capability as well as LUFS (Loudness Unit Full Scale) control mix to a stereo pair for remote control via a web browser.

Rolling packet capture measurement
This mode supports continuous capture of data packets in loop mode, simplifying troubleshooting if an error is detected.
