Joop Talstra received his M.A. and Ph.D., both in physics, from Princeton University. After joining Philips Research in 1997 he worked on copy-protection methods such watermarking and encryption, for optical recording systems (DVD and Blu-ray) for almost 10 years. After a brief stint in lighting control systems he moved to Philips’ corporate standardization department, where since 2010 he has been heading the section handling standards in the consumer electronics space, such as for codecs, optical recording and connectivity.
High Dynamic Range (“HDR”) video is seen by many as the main next step in improved immersive experience for the consumer. A new video standard is needed to convey HDR video from the studio to the consumer. Such standard must not only provide high quality HDR video, but also:
· allow low-cost decoding to enable adoption by CE industry;
· have a minimal impact on existing transmission/storage channels, i.e. low additional bit rate compared to Standard Dynamic range (“SDR”) video;
· allow an efficient content creation workflow;
· address the wide variety of HDR displays that will be in the market.
Philips developed a parameter-based HDR system that fulfils these requirements. Philips HDR has been adopted as optional HDR technology for Ultra-HD Blu-ray.
