The vast majority of video content existing today is in Standard Dynamic Range (SDR) format and there is a strong interest in upscaling this content for upcoming High Dynamic Range (HDR) displays. Tone expansion or inverse tone mapping converts SDR content into HDR format using Expansion Operators (EO). In this paper, we show that current EO’s do not(More)
In November 2014, MPEG released a new standard, named Green Metadata, that enables energy-efficient media consumption on consumer devices [4]. This standard specifies metadata for reduction of power consumption during encoding, decoding and display. It specifies in particular some metadata for energy-efficient media selection using DASH standard [3]. This(More)
Current increasing effort in the television industry towards High Dynamic Range (HDR) imaging has raised the issue of the compression of HDR content. Offering a higher peak luminance and wider color gamut, HDR video introduces new challenges to the state-of-the-art video codecs such as High Efficiency Video Coding (HEVC) or VP9, which have been designed and(More)
High Dynamic Range (HDR) is the latest video format for display technology and there is a strong industrial effort in deploying an HDR capable ecosystem in the near future. However, most existing video content today are in Standard Dynamic Range (SDR) format and there is a growing necessity to upscale this content for HDR displays. Tone expansion, also(More)
With the current progress in microelectronics and the constant increase of network bandwidth, video applications are becoming ubiquitous and spread especially in the context of mobility. In 2019, 80% of the worldwide Internet traffic will be video. Nevertheless, optimizing the energy consumption for video processing is still a challenge due to the large(More)
