    Abstract: An example device for retrieving media data includes a memory configured to store video data; a video decoder configured to decode the video data; and one or more processors implemented in circuitry and configured to: determine that a media presentation includes first video data at a first spatial resolution and second video data at a second spatial resolution, the second spatial resolution being different than the first spatial resolution; receive a first portion of the first video data at the first spatial resolution for a first playback time; send the first portion of the first video data at the first spatial resolution to the video decoder; receive a second portion of the second video data at the second spatial resolution for a second playback time later than the first playback time; and send the second portion of the second video data at the second spatial resolution to the video decoder.

    Abstract: A client device (e.g., user equipment or “UE”) may be configured to engage in a media communication session, such as a WebRTC session, with another client device. The client devices may separate a quality of service (QoS) specification from a QoS flow definition, to allow for separate interactive connectivity establishment (ICE) negotiation. The QoS specification may cover all segments of a connection for the media communication session. For example, QoS may be requested for a case where a server (e.g., a Traversal Using Relay Network Address Translation (TURN) server) is hosted by a mobile network operator (MNO). The QoS specification and the QoS flow description may be linked.

    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: An example device for presenting media data includes a memory configured to store media data defining one or more virtual objects in a virtual scene; and one or more processors implemented in circuitry and configured to: receive a scene description of a bitstream including the data describing the one or more virtual objects in the virtual scene and a scene anchor, the scene anchor representing a correspondence between the virtual scene and a real-world presentation environment; determine the correspondence between the virtual scene and the real-world presentation environment using the scene anchor; and present the one or more virtual objects at locations within the real-world presentation environment according to the determined correspondence.

    Abstract: An example device for retrieving media data, the device comprising: a memory configured to store scene data and image data; and one or more processors implemented in circuitry and configured to: receive data for a bitstream indicating that the bitstream includes one or more overlay images, the overlay images comprising either a single static image to be presented with scene data that remains constant while being presented frame-by-frame with frames of the scene data or an image sequence that repeats with a regular periodicity while being presented frame-by-frame with the frames of the scene data; receive the one or more overlay images from the bitstream; receive the scene data including one or more scene images; and present the scene images and the overlay images.

    Abstract: A device for processing video data can be configured to receive a configuration record for decoding a bitstream of the video data, wherein the configuration record for the bitstream includes a toolset indication syntax element that includes information identifying, from a set of video decoding tools, tools that are required to decode the bitstream associated with the configuration record; based on the toolset indication syntax element, determine whether to retrieve the bitstream associated with the configuration record; and based on the determination to retrieve the bitstream associated with the configuration record, retrieve the bitstream and outputting the bitstream to a video decoder for decoding.
