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

Lawo’s vm_dmv is a new virtual module (VM) for Lawo’s V__matrix IP routing & processing platform, complementing the existing vm_mv, 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_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 18 SDI inputs) or network (2x 40GbE) I/O. These sources are downscaled by the vm_mv64-4 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 (or two UHD mosaics) with up to 64 sources/PIPs each (128 each in UHD). 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_dmv64-4 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 infinitely 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.
