vm_dmv - World’s 1st Flexibly Expandable True IP Multiviewer

Lawo’s vm_dmv is a virtual module app (VM) for Lawo’s 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, flexibly 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_dmv 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 Lawo LiveView™ IP streams.

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

As any vm_dmv can use any LiveView™ stream from any other vm_dmv on the network it scales linearly with each vm_dmv app that is added to the network which results in a flexibly expandable and distributed multiviewer.

The result is not only the world’s first 1st flexibly 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.

NEW: LiveView™ Decoding Engine
This server-based solution enables the V__matrix vm_dmv multiviewer to show both production (ST2110/ST2022-6) and
transmission (MPEG/OTT) formats on the same screen for complete end-to-end visibility. The LiveView™ Decoding Engine
integrates full frame rate MPEG-2/H.264/HEVC decoding for any Lawo LiveView™ enabled product.
