Abstract: A media device pre-fetches media data that is likely to be retrieved. An example media device includes a memory for storing media data, and one or more processors implemented in circuitry and configured to receive information indicating at least one data structure of a plurality of data structures that is likely to be retrieved by a plurality of user devices operated by a respective plurality of users, the data structure including media data, and retrieve the media data of the data structure before receiving requests for the media data from the user devices. The information may be included in, e.g., a manifest file, a special Parameters Enhancing Delivery (PED) message, and/or a separate track of a video file multiplexed with other tracks of the video file.

Abstract: An example device for generating quality measurement reports includes one or more hardware-based processors implemented using digital circuitry, the processors being configured to execute a middleware unit and a target application for media data. The middleware unit is configured to receive media data via broadcast or multicast from a server device, generate reception reports covering the reception of the media data according to received reporting directives, deliver at least part of the media data to a target application of the client device, receive quality of experience (QoE) reports from the target application, and provide contents of the QoE reports to a reception reporting server.

Abstract: Systems and techniques are described for processing media content, such as samples of sparse media content whose sample durations can be unknown at the time of decoding the samples, include obtaining, at a current time instance, a current fragment comprising at least a current time component. From the current time component, a modified duration is obtained for at least one media sample, the modified duration indicating a time duration by which a presentation of a previous media sample of a previous fragment is to be extended or reduced in relation to the current time instance. The at least one media sample is presented for a time duration based on the modified duration.

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.
