Abstract
A scheme for managing bandwidth in a multi-client environment including one or more ABR clients and, optionally, one or more non-ABR clients. When a request for media segments from an ABR client device is detected, the manifest referencing multiple bitrate representations of a media segment is modified wherein references of all but a selected single bitrate representation are removed. The modified manifest referencing the selected single bitrate representation is provided to the ABR client device. Regardless of the selected single bitrate representation referenced in the modified manifest, a particular bitrate representation of the requested media segment determined responsive to a bandwidth allocation mechanism is provided to the ABR client device.
