Software-Defined NDI & IP Video Infrastructure for Modern Media Workflows

Altered Images is proud to be an approved Sienna partner, providing customers with access to one of the industry’s most comprehensive software platforms for NDI and IP-based broadcast infrastructure.

For over 30 years, Sienna has been developing innovative technology for the broadcast, post-production, live production, corporate and AV industries. Today, its software powers facilities around the world, helping organisations move away from traditional hardware-based infrastructure towards flexible, scalable IP workflows that can be deployed on-premises, in the cloud or as hybrid environments. Sienna is developed by Emmy Award-winning Gallery Sienna and is trusted by broadcasters, production companies and enterprise organisations in more than 50 countries.

Modernise Your Broadcast Infrastructure

As production workflows continue to evolve, organisations need infrastructure that is flexible, scalable and easy to manage.

Rather than relying on multiple dedicated hardware devices for routing, signal processing, monitoring and conversion, Sienna delivers these capabilities through powerful software applications. This enables broadcasters and production teams to build highly efficient IP-based facilities while reducing hardware requirements, rack space and operational complexity.

Whether you’re operating a traditional broadcast facility, expanding into remote production or building a cloud-first workflow, Sienna provides the tools needed to create reliable, future-ready production environments.

Key Sienna Technologies

ND Processing Engine

At the heart of the Sienna platform is the ND Processing Engine — a modular software environment designed to replace traditional broadcast “glue” equipment.

It combines hundreds of processing modules into a single platform capable of performing tasks such as:

• Signal processing
• Audio embedding and de-embedding
• Up/down/cross conversion
• Multiviewers
• Vision mixing
• Audio mixing
• Monitoring
• Recording
• HDR and colour processing
• Browser-based contribution
• Intercom
• Workflow automation

Because everything runs within a single software platform, workflows can be reconfigured quickly without replacing hardware, making it ideal for facilities that need flexibility and scalability.

NDI Router

The Sienna NDI Router provides a familiar routing experience for facilities moving from SDI to IP.

Designed to emulate traditional broadcast routers while operating entirely within NDI environments, it allows operators to route video sources instantly across a network using existing control systems, automation platforms and hardware router panels.

The router supports facilities ranging from small production environments to enterprise-scale installations with routing matrices of over 2,000 x 2,000 sources and destinations, all without creating network bottlenecks.

Cloud & Hybrid Workflows

Sienna has been designed with cloud production in mind.

Its software can run on-premises, within public cloud platforms or across hybrid environments, enabling teams in different locations to collaborate securely while maintaining low-latency production workflows.

This flexibility makes Sienna ideal for organisations looking to expand remote production capabilities or gradually migrate from SDI to IP without replacing existing infrastructure overnight.
