Abstract:Video streaming, either in terms of Video On Demand (VOD) or live streaming, has grown dramatically during the past few years. In compare to traditional cable broadcasters whose contents can only be watched on TVs, video streaming is ubiquitous and viewers can flexibly watch the video contents on a wide variety of devices - from smart phones to laptops and large TV screens. Such ubiquity and flexibility is enabled by interweaving multiple technologies, such as video compression, cloud computing, and content delivery. As video streaming gains more popularity and dominates the Internet traffic, it is essential to understand how it operates and the interplay of different technologies involved in it. Accordingly, the goal of thispresentationis to unveil the mysterious processes of delivering a raw captured video to viewers’ devices. In particular, it will elaborate on the video encoding, transcoding, packaging, encryption, and delivery processes and survey recent efforts in academia and industry.
