Abstract<\/strong><\/span><\/p>\n

Digital videos have become omnipresent along the last few decades. Besides the many applications adopting video technologies, entertainment has grown rapidly due to the massive adoption of streaming services such as Netflix, Amazon Prime, Disney+, Globoplay, and many others. The COVID-19 pandemic further pushed the demand for video services related to home office and remote education. On top of that, users’ demand for ever-increasing video quality and immersion lead to higher resolutions (4K and 8K UHD), frame rates (60 fps, 120 fps), and color depth (HDR). The huge amount of data necessary to represent such contents brings a series of challenges related to video transmission and storage. In this scenario, efficient video compression becomes mandatory. This talk will present the basic concepts of video compression used in current video encoders, as H.264\/AVC, HEVC, VP9, VVC, and AV1. The main algorithms and techniques to efficiently compress a video will be presented, as well as a generic video encoder and the complete process from an input video (uncompressed) to an encoded video stream. A brief introduction to the main encoding tools of the state-of-the-art video encoders will be discussed.<\/p>\n
