The European Broadcasting Union (EBU) has chosen Video Clarity’s ClearView Extreme 4K video quality analyser for use in numerous research projects. The technology is being used for interactive research forums, standards projects, seminars, and working meetings to advance the use of 4K video format processing in next-generation television formats.
The Extreme 4K analyser combines high-rate playback and side-by-side analysis with perceptual video quality measurements. It provides native, interactive visual comparison playback of two independent sequences that can be compared in multiple viewing modes such as side by side, A minus B, or split mirror on a single monitor.
The analysers enable the EBU to perform visual and measured quality testing on new processing technologies and new IP infrastructure deployments for 4K resolution. The ClearView 4K logs and saves every test, enabling EBU engineers to recall every finding instantly for additional visual confirmation. The data also provides a historical record of the work that can be used in presentations at developer seminars and as background for study papers written by the EBU as it formulates technical standards.
"As broadcasters and service providers investigate next-generation services such as UHDTV, a critical success factor will be testing and analysis tools that can support emerging formats such as 4K. Therefore, much of our research efforts are focused on the quality testing required for 4K broadcasting, especially as it relates to new encoding technologies such as HEVC," said Adi Kouadio, senior project manager, EBU. "ClearView 4K's ability to make visual comparisons and measure the quality of a source versus a processed version of any video type is essential to our research efforts and was of great use establishing the right contribution profiles for the FIFA World Cup 4K transmissions."
