Lawo’s V__matrix platform sees an update released for the vm_udx application that turns V__matrix C100 software-defined processing blades into up/down/cross converters with up to eight paths of format conversion and up to four 3D LUT colour space conversion paths.

In the light of a rapidly growing trend towards remote maintenance, vm_udx’s web UI allows operators to monitor which video content is currently processed by a given C100 blade. The new Live Video Preview display allows users to visualise the video content received by an SDI or IP input, or the output of a processing stage, directly in vm_udx’s web UI.

Lawo V_matrix vm_udxIn response to vm_udx user requests, Lawo has enhanced the +hdr colour space 3D LUT conversion engine. Each of the four vm_udx paths now features tetrahedral interpolation for conversions between a variety of colour spaces.

To support flexible audio workflows, vm_udx adds a range of new features. A newly designed downmix engine with 2,048 mono-equivalent inputs into 256 mono-equivalent summing buses can be freely configured for flexible mono or stereo summing as well as dedicated 5.1 > stereo or 7.1 > stereo downmixing.

The digital gain range for all audio levelling instances has been extended to support level adjustments between –∞ and +24dB. In addition, vm_udx is able to interface with a Madi environment simply by adding the optional +madi licence and communicating with the SDI rear plate connected to the processing blade that hosts the Up/Down/Cross Converter. BNC connectors can be software-switched to Madi in almost any combination.

The new release further supports metadata workflows with an advanced ancillary-data handling engine. Able to handle ANC data in 2110-40, 2022-6 and SDI signals simultaneously during the conversion process, users are free to keep, or remove, individual DID/SDID contained in the ANC payload.

The new +tc_gen licence generates time code flavours from PTP or other time sources and provides up to three independent generators. Generated Ancillary Time Code (ATC) formats, which can be embedded into TX and SDI outputs, include VITC1, VITC2, and LTC. Linear Time Code (LTC) can be generated as a digital audio signal.

‘With this new release, the vm_udx app boasts advanced audio and ancillary data handling which complements its powerful up/down/cross video feature set,’ says Lawo Senior Product Manager for Media Infrastructure, Stephan Türkay. ‘The software-defined nature of Lawo’s V__matrix ecosystem inherently means that its feature set can evolve as market requirements change. This flexible approach allows V__matrix users to operate at the cutting edge for many years to come.’
