    Abstract: An example device for retrieving media data includes a memory configured to store media data; and one or more processors implemented in circuitry and configured to: receive data indicating a packet loss signaling mechanism, the packet loss signaling mechanism comprising at least one of that segments are sent in chunks, that transport object identifiers (TOIs) are sequential, or that a last packet of an object assigned to a TOI has a specific flag set in a header of the last packet, a base URL, a maximum latency, or a synchronization point in a file delivery header; detect loss of a packet using the at least one of the packet loss signaling mechanisms, the lost packet including missing media data; generate a byte range request for the missing media data using information of the file delivery header; and deliver a proper media object to a media application.

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, a network may establish a multiple access (MA) packet data unit (PDU) session for a local area data network (LADN) and may reconfigure a registration area to map to a LADN service area. A network may establish an MA PDU session for an LADN, but may steer traffic to only one of two access links. A network may reject a request for an MA PDU if it is for an LADN. A user equipment (UE) may be configured to trigger a UE registration update or other location information if it leaves an LADN service area while in an idle mode with one access network and a connected mode with the other access network. A UE may request LADN registration, and the network may provide the UE with an indication that MA PDU sessions for the LADN are not supported.

    Abstract: In one example, a device for retrieving media data includes a memory configured to store media data, and one or more processors implemented in circuitry and configured to retrieve a file including the media data, web content formatted according to hypertext markup language (HTML), and data indicating how to synchronize the web content with the media data, and present the media data and the web content, wherein to present the media data and the web content, the one or more processors are configured to synchronize presentation of the web content with presentation of the media data according to the data indicating how to synchronize the web content with the media data.

    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.

    IPC: H04L29/06

    Abstract: An example device for retrieving media data includes a streaming client and a media presentation application configured in one or more processors implemented in circuitry. The streaming client is configured to determine a start time for an event message corresponding to an interactivity window during which one or more application-specific interactivity events can occur during presentation of media data, the application-specific interactivity events comprising times during which a user of the device can interact with the presented media data, determine an end time for the event message corresponding to the interactivity window, receive data representative of at least one of the application-specific interactivity events during the interactivity window corresponding to the event message, and forward the data representative of the at least one of the application-specific interactivity events to the media presentation application.
