Announcement: High Dynamic Range Television: An advance in TV viewing experience
Monday 5th of September 2011
Researchers at the University of Warwick, together with partners: goHDR Ltd. and Altera® Toronto Technology Center have developed an embedded system that can be connected to existing televisions, allowing them to display High Dynamic Range (HDR) content.
HDR video captures a wider range of light intensity levels found in real scenes ranging from direct sunlight to lowlight images. HDR imagery offers a significantly enhanced viewing experience even when the higher contrasts are reduced (through appropriate luminance compression algorithms, known as tone mapping) for display on Low Dynamic Range (LDR) devices, such as in computer monitors or televisions. This enhanced experience allows the viewer, for example, to clearly see the details of a racing car when it enters or leaves the tunnel. Furthermore, the increased lighting of HDR content provides better depth perception, allowing a 3D viewing experience without the need to wear special glasses.
The partners will be showcasing the HDR-enabled TV at the IBC 2011 event in Amsterdam (hall 8, stand 8.G41) from 9-13 September. Started in 1967, IBC is now one of the premier annual events for broadcast professionals. Last year it attracted over 48,000 people from 140 countries.
Professor Alan Chalmers said:
“This project has brought together worldwide expertise in HDR imaging from the University of Warwick with the innovation and in-depth market knowledge of goHDR and Altera. Together the partners have demonstrated the technical and commercial viability of HDR enabled television.”
“HDR video has very large data and computational requirements. This creates significant challenges for video processing on a low power embedded platform such as a television or set-top box. Our project comprises highly novel system in which compressed HDR video content is carefully streamed from goHDR’s compression algorithm to an Altera Field Programmable Gate Array (FPGA) which exploits massive amounts of parallelism to achieve high processing rates at a fraction of the power required by other solutions. The goHDR’s compression is specifically designed for HDR video and is able to achieve at least 100:1 compression with minimal perceptual loss.
At IBC Professor Chalmers and partners will demonstrate the HDR-enabled system working with a standard LED TV. In addition to a demonstration of a variety of HDR footage, the short film, “Morgan Lovers” will be presented. This film was shot, manipulated, and can be displayed entirely in HDR. It was a collaborative venture with local film maker, Vermillion Films, and Morgan Cars.
