NDI® 6 (Network Device Interface) is the latest and most significant evolution of the industry-standard IP video protocol developed by Vizrt. While previous NDI versions were primarily optimized for high-speed local area networks (LANs), NDI 6 breaks those boundaries by natively integrating professional **WAN (Wide Area Network) connectivity** and broadcast-grade **HDR (High Dynamic Range)** color pipelines.

Note: While the standard ZowieBox operates on NDI 5.5, the next-generation ZowieBox Pro natively integrates NDI 6 (currently NDI 6.3), unlocking premium cloud and broadcast capabilities directly on-device.

Here are the key core advancements of NDI 6 and how they empower the ZowieBox Pro:

• Native 10-Bit HDR (High Dynamic Range) Support: NDI 6 introduces comprehensive support for 10-bit HDR video (supporting PQ and HLG formats). When encoding or decoding with ZowieBox Pro, this ensures true-to-life contrast, incredibly deep blacks, brilliant highlights, and a wider color spectrum. It meets the rigorous requirements of modern broadcast networks and high-end commercial productions.
• Built-In NDI Bridge (The WAN Revolution): Historically, sending an NDI stream to a remote studio across the internet required complex VPN routing or external hardware setups. NDI 6 solves this by integrating **NDI Bridge** directly into the core standard. ZowieBox Pro natively supports **NDI Bridge (Join)**, meaning it can securely connect and transmit its local NDI stream to an NDI Bridge host anywhere in the world over standard internet connections with extreme ease.
• Next-Level NDI® | HX3 Efficiency: ZowieBox Pro leverages NDI 6’s optimized NDI® | HX3 standard. It delivers pristine, visually lossless video quality that is virtually indistinguishable from Full NDI, but at a fraction of the bandwidth (typically requiring only 10% to 20% of the network overhead). This makes high-fidelity 4K60 IP streaming incredibly stable over standard network infrastructures.
• Enhanced Audio and Metadata Synchronization: NDI 6 drastically improves clock synchronization across multiple video and audio streams. When utilizing ZowieBox Pro’s multi-channel audio setups, NDI 6 ensures perfect lip-sync and precise timing between separate audio and video feeds, eliminating drifting issues in complex live multi-camera switchers.
• Better Network Congestion Control: The protocol updates in NDI 6 provide vastly superior handling of packet loss and network jitter. Combined with the ZowieBox Pro’s powerful hardware processing, your streams maintain rock-solid stability even on unpredictable or high-traffic shared networks.
