SYSTEM AND METHOD FOR MANAGING SEGMENT DELIVERY AND BANDWIDTH RESPONSIVE TO ENCODING COMPLEXITY METRICS

摘要

A complexity-driven adaptive quality scheme for managing segment delivery and bandwidth allocation in an ABR network. Segments for downloading to a requesting ABR client may be selected based on encoding complexity data associated therewith, wherein a virtual segmenter may operate to represent the media segments in a memory using associated pointers. In a bandwidth management configuration using a WFQ scheduling mechanism, delivery weights may be modified based on the complexity data.

1. A method operating at an adaptive bitrate (ABR) network node, the method comprising:
obtaining encoding complexity metric (ECM) information associated with one or more ABR representations of a media asset wherein the one or more ABR representations each comprise a stream of segmented content of the media asset encoded at a particular bitrate; and providing the ECM information to a stream delivery server for facilitating at least one of complexity-driven segment delivery and bandwidth management with respect to delivering the media asset to an ABR client device.
