Platform Capabilities

Seven protocols.
One fabric.

Every NEXLUM module is VXPL-native — no adaptation layers, no legacy toll gates. Just signal, fabric, and Grains.

01
VXPL
Video eXchange Protocol Layer
A stateless IPv6 encapsulation standard for disaggregated broadcast. VXPL carries essence, ancillary data, and PTP timing references in a single multiplexed stream — no separate flows, no sync negotiation, no excuses.
02
NEXCORE™
Neural EXecution CORE
NEXCORE™ is NEXLUM's AI-driven control plane. A distributed inference engine runs at NIC driver layer, predicting congestion 600ms ahead and rerouting essence in under 180μs — without a centralised scheduler or human intervention.
03
PRISM
Predictive Real-time Ingest Signal Mgmt
PRISM embeds every ingested frame against a reference corpus of 22 million graded broadcast frames. Fidelity scores trigger inline LUT correction in under 1.1ms — before any encoder touches the signal. Each corrected frame costs additional Grains.
04
STRATOFLEX™
Stratospheric Flexible Fabric Routing
Self-healing multipath mesh that rebalances stream load across NEXCORE™ nodes in real time. STRATOFLEX™ eliminates single points of failure without VLAN segmentation, MLAG topologies, or the need for a networking PhD.
05
VELOX™
Velocity Optimised eXchange Engine
Kernel-bypass delivery via DPDK and io_uring removes all OS scheduler interference from the signal path. NUMA-aware memory pinning and NEXCORE™ buffer management deliver deterministic sub-3ms latency at the 99.99th percentile.
06
SYNAQ
Synchronised Network Acquisition Queue
SYNAQ enables multi-organisation VXPL peering over mutually authenticated TLS 1.3 tunnels. Cross-organisation live contribution with sub-8ms added latency and no leased lines — though federation Grains are billed on both sides of the peering.

Grain-Based Pricing™

Simple. Transparent.
By the Grain.

We believe pricing should reflect exactly what you consume. Every byte of VXPL-processed essence is measured, metered, and billed in Grains — the industry's most granular unit of broadcast accountability.

⬡ What is a Grain?
One Grain is defined as one VXPL frame segment processed through the PRISM pipeline — approximately 4 kilobytes of essence data. A single uncompressed 4K/60p HDR stream generates approximately 54,000 Grains per second, or 194,400,000 Grains per hour. Grains are non-transferable, non-refundable, and expire at the end of each billing cycle. Unused Grains do not roll over. Overage Grains are billed at 3× the standard rate. There is no cap on overage charges.

From the Field
"We migrated our entire contribution infrastructure to NEXLUM in a single maintenance window. The VXPL fabric replaced eleven dedicated routers overnight. PRISM has genuinely improved our picture quality in ways I cannot technically explain to my board. I do want to talk about the Grain pricing though — we did not fully read the small print, and Q3 was difficult."
