HTTP adaptive streaming (HAS) has become the technology of choice for delivering video content over the Internet. We first show that when multiple HAS clients share a network bottleneck, bad things happen. To address the problems, we present a number of solution approaches. Second, we discuss the ways to achieve consistent-quality streaming. Third, we look into some of the recent developments in DASH and CMAF standards. Throughout the talk, we describe a number of open research issues and discuss future directions in this space.HTTP adaptive streaming (HAS) has become the technology of choice for delivering video content over the Internet.
