Abstract:
In one example, a device includes one or more processors configured to determine that a manifest file for media content indicates that the media content includes a first period and a second period, that the manifest file indicates that the first and second periods are continuous, and that advertisement media data is available for insertion between the first and second periods, select a first adaptation set in the first period based at least in part on characteristics signaled for the first adaptation set, retrieve media data of the first adaptation set based on the selection of the first adaptation set, retrieve the advertisement media data, and retrieve media data of a second adaptation set in the second period that the manifest file indicates is associated with the first adaptation set based on the selection of the first adaptation set and store the retrieved media data to a memory.
Abstract:
Content (e.g., multimedia streams, audio-video streams, video files, text, etc.) may be delivered to receiver devices over a broadcast channel and/or via a broadcast network via components (e.g., servers, receiver device, software applications, modules, processes, etc.) configured to communicate the content in a manner that reduces the amount of information communicated over the broadcast network, reduces the amount network bandwidth consumed by the communication, meets precise timing requirements for the individual objects that are communicated, and enables each receiver device to receive, decode, and render the content without consuming an excess amount of that receiver device's battery or processing resources.
Abstract:
A proxy unit is configured to obtain mapping information that maps an identifier for media data to a resource location based on a service for retrieving the media data, wherein the service defines at least one of a plurality of types of transports for transporting the media data, receive a request for the media data from an application service client, determine whether the service is available, and, when the service is available, cause the application service client to receive the media data from a unit that receives the media data using the service from the resource location, based on the mapping information. In this manner, the application service client may receive media data from the unit (e.g., a middleware unit), which then receives the media data using a service that defines transport according to, e.g., broadcast or multicast transport, or another fashion (e.g., unicast) if the defined transport is unavailable.

Abstract:
The present disclosure relates to methods and devices for facilitating using a streaming manifest including a profile signal for content encoded based on a encapsulation format. An example method disclosed herein includes identifying structures associated with first media, wherein the first media is associated with a first streaming format. The example method also includes generating a streaming manifest for the first media, wherein the streaming manifest maps the structures associated with the first media to structures associated with a second streaming format, and including an indication with the streaming manifest, wherein the indication identifies the streaming profile used to map the structures.
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.
