V__matrix – Software-defined IP-Routing, Processing & Multi-Viewing Platform

Flexible - forceful - future-proof

Some call it cloud, some call it virtualization – we call it: V__matrix. This new IP broadcast video core infrastructure product will change your idea of what a broadcast facility looks like from legacy to future, quickly transforming any broadcast installation into a flexible, future-proof production facility, addressing a wide range of workflows and supporting your transition to a totally IP-based environment.

V__matrix is the first of its kind. Free from the restrictions of legacy hardware platforms it offers a completely virtualized real-time routing and processing infrastructure. Instead of connecting single purpose modular products in elaborate production chains the V__matrix is based on data center principles of flexibility, fabric computing and COTS economics and makes these available to any live production broadcast environment. Whether an OB truck, a TV studio or a broadcast operation center, V__matrix creates a fully virtualized core infrastructure.

The V__matrix ecosystem is based on generic high capacity FPGA based core processing modules upon which Virtual Modules (VM) are loaded to create the functionality required. Multiple cores are connected through redundant 40GE (or 4x10GE) Ethernet interfaces to an IP network to form a distributed IP routing and processing matrix that provides frame-accurate, clean switching just like a legacy baseband matrix.

The V__matrix ecosystem scales linearly from tens to thousands of I/O and processing functions which make it ideal for any size live broadcast facility, small or large. Capabilities easily scale as well. An entire production workflow can be remapped in minutes when requirements change from production to production. The functionality of any processing blade can be exchanged, enabling system capabilities to easily be modified or upgraded to address your constantly changing business requirements. The V__matrix pool of generic processing blades provides ultimate flexibility; with software-defined functionality they can be configured and called upon to handle the peaks and troughs of seasonal production demands.

With Lawo’s innovative licensing model, Virtual Modules can be assigned to a particular processing blade or be stored in an on-site license server allowing for unprecedented flexibility.

Virtual Multiviewer Modules for V__matrix

vm_mv – 4K Multiviewers

The V__matrix vm_mv24-4, vm_mv18-4 and vm_mv16-4 virtual modules (VMs) provide high quality multiviewer functionality to the V__matrix ecosystem when loaded onto a c100 processing blade.

Capable of handling both IP and SDI sources the V__matrix multiviewer virtual modules can monitor uncompressed 4K/UHD, 3G, HD and SD video as well as both embedded and discrete audio while generating pixel perfect mosaics with ultra-low  latency.

The vm_mv24-4 can monitor up to 24 simultaneous sources from a combination of IP or SDI video while the vm_mv18-4 and vm_mv16-4 can monitor 18 and 16 sources respectively. All three multiviewer VMs can generate up to 4 x 3G output heads (1 at 4K) and scale and display any source on any output head without limitation. The same source can be displayed on multiple output heads at different resolutions. The output heads can be configured as either HD, 3G or 4K and output over IP as ST2110/2022 or, using the modular I/O rear-plate, as SDI.

The V__matrix multiviewer VMs were designed to be controlled by Lawo’s groundbreaking touch operated confi guration system “theWALL”. This unique HTML5 based GUI makes mosaic confi guration with borders, colors, UMDs, tally etc a simple case of drag and drop.

Distributed 4K IP Multiviewer

Lawo’s vm_dmv is a virtual module (VM) for the V__matrix IP routing & processing platform, complementing the existing vm_mv16-4, vm_mv18-4 and vm_mv24-4 multiviewer line-up. It turns the V__matrix C100 software-defined processing blade into a distributed, infinitely expandable, true IP multiviewer.

The vm_dmv is based on a distributed architecture where multiple modules network together. These modules could be hosted together in the same V__matrix frame, in different frames or even at different geographical locations. Basically anywhere as long as they are networked together via IP.

Every vm_dmv256-4 has an input stage capable of receiving up to 24 sources of any combination of 4K/3G/HD/SD which is limited only by the physical (up to 12 SDI inputs) or network (2x 40GbE) I/O. These sources are downscaled by the vm_dmv and returned to the network as IP (RFC 4175) encapsulated mipmaps.

In parallel to the input stage, every vm_dmv also features an output stage capable of creating up to four 3G mosaics (one 4K mosaic) with up to 64 PIPs each (128 in 4K). The output stage compiles a mosaic from the appropriate mipmaps needed, automatically taking into account the size the user requests for the PIPs. The output stage can both use mipmaps that it has generated by its own input stage or by subscribing to other mipmaps from the network.

As any vm_dmv can use any mipmaps from any other vm_ dmv on the network it scales linearly with each vm_dmv that is added to the network which results in an “infinitely” expandable and distributed multiviewer.

The result is not only the world’s first 1st infi nitely expandable multiviewer, it’s also a solution that significantly reduces rackspace, weight and power-consumption. In addition, Lawo’s V__matrix platform is already renowned for its software-defined functionality where C100 blades can be changed at run-time by loading different virtual modules.
