Abstract: A device for retrieving media includes a memory configured to store media data of a media presentation; and one or more processors implemented in circuitry and configured to: retrieve a manifest file for a media presentation indicating that container parsing of media data of a bitstream can be started at a resync point of a segment of a representation of the media presentation, the resync point being at a position other than a start of the segment and representing a point at which the container parsing of the media data of the bitstream can be started; use the manifest file to form a request to retrieve the media data of the representation starting at the resync point; send the request to initiate retrieval of the media data of the media presentation starting at the resync point; and present the retrieved media data.

Abstract: In embodiments of systems and methods for managing end-to-end Quality of Service (QoS) in a communication path spanning a first communication network and a second communication network may include determining by a network element of the first communication network an end-to-end QoS requirement for communicating packets from a packet source to a packet destination via the communication path, determining by the network element a QoS provided by the second communication network within the communication path, and configuring the first communication network to provide sufficient QoS to support the end-to-end QoS requirement based on the QoS provided by the second communication network.
