We are a group of independent broadcast engineers

About

We focus on automation and optimization solutions for broadcasters and post-production houses.

Open-source software creates a cornerstone of our work and we are proud of it.

While developing our own software, we also provide integration and training services for other OSS products.

Nebula

Our flagship - Nebula - is an open source media asset management and broadcast automation system.

Powerful and stable enough to run 24/7 multichannel TV or radio broadcast on-premises or in a shared environment with a great emphasis on simplicity, modularity, and speed.

Problemsolving

We solve problems. Thanks to our experience we obtain mastery over optimization and fixing workflows regardless of suppliers and existing technology.

We focus on making processes automated followed by cost reduction.

The software

Ingest

We normalize and transcode all incoming files to the production format.

This process includes metadata extraction, aspect ratio fixing, crop and rotation detection, smart frame rate and size normalization and EBU R128 loudness correction.

Manage

Nebula uses extendable, EBUCore based metadata model backed by a powerful database engine.

Python scripting allows limitless extensibility and automation.

Schedule

Nebula uses Dramatica engine - template based scheduler with a smart solving algorithm.

This enables automatic or semi-automatic playlist creation including "selector style" music blocks solving.

Playout

Using reliable hardware with CasparCG software, our playout servers are suitable for 24/7 multichannel playback in various resolutions and frame rates.

Graphics

In-house developed CG rendering library is the perfect complenent to CasparCG and enables rendering of tickers, complex charts or tables from assets metadata or any other data source.

Distribute

We are able to deliver high quality video stream to publishing point of your choice or to most streaming platforms our own CDN service.

Batteries included

Sport 5 master control room

We won't walk out after initial technology setup.

Our open, modular architecture allows maximum reusability of the existing technology on-site. We learn from each and every setup and work to share the knowledge we acquired during over a decade of experience.
