Abstract
A scheme for managing delivery of segmented media content in an ABR network, wherein bitrates of a manifest file may be selectively modified or removed based on a client device's video buffer characteristics. An ABR stream delivery server is operative to simulate the client device's video buffer in a streaming session and accordingly modify the manifest files to include metadata for media segments encoded at a particular single bitrate responsive to the buffer performance and other network conditions. Responsive to monitoring the video buffer characteristics of the media player during the streaming session, a selected single bitrate may be moved up or down to other bitrates of the manifest files.
