coralbay.tv releases UHD Playout with New High-Density HDR Pipeline and GPU Acceleration

 

LEEDS, UK, 1st April, 2026 — coralbay.tv, a leader in cloud-native playout, today announced a significant update to its coralPlay video pipeline. The latest release introduces comprehensive support for Ultra High Definition (UHD) and High Dynamic Range (HDR) workflows, delivering a leap in channel density and agility for broadcasters.

 

As the industry transitions to higher resolutions and more vibrant color spaces, coralPlay now provides full support for UHD 4K 2160p (BT.2100), including HLG at p50 and p59.94. To ensure seamless integration into existing hybrid environments, the update includes built-in HDR-to-SDR conversion (and vice-versa). This utilizes a mathematically precise, deterministic conversion process to maintain the absolute integrity of the original source, avoiding the unpredictability of AI-based scaling.

 

Technical excellence remains at the core of the coralPlay architecture. This update introduces full support for 10 and 12-bit color depths. To handle the massive throughput required for real-time UHD we have implemented an optimized compositor utilizing AVX2 and AVX512 instruction sets.

 

“Our goal is to provide the most efficient and versatile playout solution on the market,” said Peter Hajittofi, CEO at coralbay.tv. “By leveraging GPU acceleration for encoding and HTML graphics rendering, we are achieving industry-leading performance. On an Amazon EC2 g4dn instance, coralPlay can run a full UHD channel using as few as five CPU cores, offering our customers incredible cost-efficiency in the cloud.”

 

Unlike alternate solutions that rely on pre-rendering video, coralPlay’s real-time video pipeline offers total flexibility, allowing broadcasters to make frame-accurate changes to schedules or graphics right up until the point of transmission, which is a critical requirement for live, reactive playout environments.

 

Key Features of the Update:

  • Enhanced GPU Utilization: Support for HEVC (GPU) codecs and GPU-assisted HTML5 graphics rendering.
  • High-Density Encoding: GPU-driven encoding for secondary records, transport stream video, and WebRTC previews to maximize channel density per instance.
  • Advanced Signal Processing: A new “frame rate matcher” and video deinterlacer to seamlessly convert p25 to p50 and i50 to p50.
  • Cloud Optimization: Minimal CPU footprint on AWS g4dn instances, significantly reducing operational overhead.

The latest version of coralPlay is available immediately, offering broadcasters a future-proof path to UHD and HDR playout without sacrificing the responsiveness that defines coralbay.tv.
