Nowadays, billions of people worldwide use a wide variety of online video services every day. Applications range from videoconferencing and video streaming to social networks and surveillance scenarios. Concurrently, recent studies have found that in 2018, roughly 1% of the global greenhouse gas emissions could be attributed to these online video services, highlighting the need for research targeting energy efficient online video systems. In this talk, we give a broad overview on the energy consumption of these systems and discuss latest research and trendsetting ideas to reduce their carbon footprint.&quot;}\" data-sheets-userformat=\"{&quot;2&quot;:769,&quot;3&quot;:{&quot;1&quot;:0},&quot;11&quot;:4,&quot;12&quot;:0}\">Light fields are a plenoptic image modality that extend traditional 2D imaging by capturing both spatial and angular information, effectively introducing a fourth dimension to visual data. This additional dimensionality enables a range of advanced applications, including immersive media, post-capture refocusing, and enhanced low-light imaging. This talk introduces the fundamentals of light field imaging and presents the JPEG Pleno Light Field Coding solution, the first International Standard for light field compression. The discussion covers key aspects of the standardization process, including the design of the reference software, the conformance testing framework, and the current status within the JPEG committee. In addition to an overview of the standard, the talk highlights ongoing research directions and recent developments in compression techniques that contribute to the evolution of JPEG Pleno Light Field Coding standard.<\/span><\/p>\n<p><span style=\"font-size: 14pt;\"><strong>Biography<\/strong><\/span><\/p>\n<p style=\"text-align: justify; padding-left: 40px;\"><span data-sheets-value=\"{&quot;1&quot;:2,&quot;2&quot;:&quot;Christian Herglotz, Germany, received the Dipl.-Ing. in electrical engineering and information technology in 2011 and the Dipl.-Wirt.
