HDR: PQ and HLG – Presented by the BBC
Original Airdate: 19 January 2017
This webcast is 90 minutes.
High dynamic range (HDR) promises to significantly enhance the viewing experience of audiences around the globe. The two HDR technologies supporting this promise are Hybrid Log-Gamma (HLG) and Perceptual Quantizer (PQ). How are they similar, and how do they differ? In this webcast, guest speakers Tim Borer and Andrew Cotton, both of the BBC, will present an objective summary of the two technologies in terms of technical parameters.
Attend the webcast and take part in a conversation about one of the industry’s hottest technology topics!
Dr. Tim Borer is a Lead Engineer at BBC Research and Development, currently focusing on aspects of UHDTV such as high dynamic range and high frame rates. He has worked in broadcasting industry for more than 30 years. Previously Tim led the video compression team at BBC R&D developing “Dirac” and the SMPTE VC-2 compression standard. Prior to the BBC he designed professional broadcasting equipment, including motion compensated standards converters and compression equipment, for both Snell and Harris. He is a co-developer of the BBC/NHK Hybrid Log-Gamma HDR solution. Tim holds degrees in video processing, electronics and physics. He is a Chartered Engineer (MIET), a senior member of the IEEE and a Fellow of the SMPTE. He is the inventor (or co-inventor) of about 20 patents.
