The success of HTTP adaptive streaming is undisputedrnand technical standards begin to converge to commonrnformats reducing market fragmentation. However, otherrnobstacles appear in form of multiple video codecs to be supportedrnin the future, which calls for an efficient multi-codecrnsupport for over-the-top services. In this paper, we review thernstate of the art of HTTP adaptive streaming formats with respectrnto new services and video codecs from a deploymentrnperspective. Our findings reveal that multi-codec support isrninevitable for a successful deployment of today's and futurernservices and applications.
