HTTP Based Adaptive Bitrate Streaming Protocols in Live Surveillance Systems

University essay from Linköpings universitet/Institutionen för datavetenskap; Linköpings universitet/Institutionen för datavetenskap

Abstract: This thesis explores possible solutions to replace Adobe Flash Player by using toolsalready built into modern web browsers, and explores the tradeoffs between bitrate, qual-ity, and delay when using an adaptive bitrate for live streamed video. Using an adaptivebitrate for streamed video was found to reduce stalls in playback for the client by adapt-ing to the available bandwidth. A newer codec can further compress the video file sizewhile maintaining the same video quality. This can improve the viewing experience forclients on a restricted or a congested network. The tests conducted in this thesis showthat producing an adaptive bitrate stream and changing codecs is a very CPU intensiveprocess.
