DPG Media deployed Yella Umbrella’s Stellar Suite inside its secure infrastructure to automate subtitle QC, enforce layout standards, and streamline open and closed caption workflows for broadcast and streaming platforms.
DPG Media, a leading Benelux broadcaster, required a secure, internally hosted solution to ensure subtitle quality, streamline QC processes, and support both open and closed caption workflows. Yella Umbrella deployed The Stellar Suite inside DPG Media’s isolated infrastructure, enabling automated quality checks, consistent layout enforcement, and efficient editing within a controlled, high-security environment.
As subtitle volumes increase and distribution platforms diversify, broadcasters require higher accuracy, consistent styling, and reduced manual intervention. DPG Media identified the need for a modern subtitling environment capable of:
– Automated quality validation
– Unified handling of open and closed subtitles
– Precise layout enforcement
– Deployment within an isolated, high security infrastructure
Yella implemented The Stellar Suite entirely within DPG Media’s protected internal network:
– Controlled access, auditing, and authentication
– Integrated with internal media pipelines and automation systems
This architecture ensures complete data sovereignty, aligning with DPG’s high-level security policies while maintaining the performance and flexibility of Stellar’s cloud architecture.
The implementation features a comprehensive QC engine that performs automated validation of:
– Line length, reading speed, and segmentation
– Subtitle overlap and timing conflicts
– Safe-area compliance and spatial layout
– Punctuation, syntax, and style conformity
Issues are surfaced through a centralized QC Dashboard, enabling editors to move directly to flagged subtitles. This reduces human error and compresses final-check timeframes.
DPG Media’s subtitle standards were formalized into style profiles, enabling:
– Automated application of corporate layout rules
– Consistent formatting across all programmes
– Reduced reliance on manual visual inspection
This ensures high-fidelity presentation for both broadcast and streaming platforms.
Stellar supports DPG Media’s dual output requirements:
– Open subtitles
– Closed subtitles
Workflows operate from a single master Task, minimizing duplication and guaranteeing consistency across distribution channels.
Efficiency is enhanced through:
– Customizable widgets for waveform, QC, timing, and video preview
– Extensive hotkey configuration for rapid navigation, timing edits, and segmentation
This enables expedited editing while maintaining precision, particularly under tight broadcast deadlines.
The on-premise deployment of The Stellar Suite provides DPG Media with a secure, automated, and standardised environment for subtitle production. The integration of automated QC, style-driven layout enforcement, unified subtitle workflows, and advanced operator tools has significantly improved quality, consistency, and throughput while meeting DPG Media’s strict security requirements.
