Interfaces between dash aware application and dash client for service interactivity support

A device for receiving media data, the device comprising:

• one or more user interfaces for presenting media data;
• and
• one or more processors implemented in circuitry and configured to execute a Dynamic Adaptive Streaming over HTTP (DASH) aware application and a DASH client, wherein the DASH aware application is configured to:
• subscribe to DASH events of a DASH event stream via a first application programming interface (API) between the DASH aware application and the DASH client, the DASH events being carried in-band with and separate from video data of a DASH media stream, the DASH events including data for interactivity-related content to be visually presented to a user of the device and to allow the user to interact with the interactivity-related content, and wherein to subscribe, the DASH aware application is configured to send data to the DASH client via the first API, the DASH aware application being configured to process data for the DASH events;
• receive data for one or more of the DASH events of the DASH event stream from the DASH client via a second API between the DASH aware application and the DASH client, the data for the one or more of the DASH events specifying the interactivity-related content, the interactivity-related content comprising content that is unrelated to media content selection;
• and
• present the interactivity-related content via the one or more user interfaces of the client device.

A device for receiving media data, the device comprising:

• means for executing a Dynamic Adaptive Streaming over HTTP (DASH) aware application to subscribe to DASH events of a DASH event stream via a first application programming interface (API) between the DASH aware application and a DASH client, the DASH events being carried in-band with and separate from video data of a DASH media stream, the DASH events including data for interactivity-related content to be visually presented to a user of the device and to allow the user to interact with the interactivity-related content, and wherein the means for executing the DASH aware application to subscribe comprises means for sending data to the DASH client via the first API, the DASH aware application being configured to process data for the DASH events;
• means for executing the DASH aware application to receive data for one or more of the DASH events of the DASH event stream from the DASH client via a second API between the DASH aware application and the DASH client, the data for the one or more of the DASH events specifying the interactivity-related content, the interactivity-related content comprising content that is unrelated to media content selection;
• and
• means for presenting the interactivity-related content.

A non-transitory computer-readable storage medium having stored thereon instructions that, when executed, cause one or more processors that execute a Dynamic Adaptive Streaming over HTTP (DASH) aware application and a DASH client to:

• subscribe, by the DASH aware application, to DASH events of a DASH event stream via a first application programming interface (API) between the DASH aware application and the DASH client, the DASH events being carried in-band with and separate from video data of a DASH media stream, the DASH events including data for interactivity-related content to be visually presented to a user of a device including the DASH client and the DASH aware application and to allow the user to interact with the interactivity-related content, and wherein subscribing comprises sending data, by the DASH aware application, to the DASH client via the first API, the DASH aware application being configured to process data for the DASH events;
• receive, by the DASH aware application, data for one or more of the DASH events of the DASH event stream from the DASH client via a second API between the DASH aware application and the DASH client, the data for the one or more of the DASH events specifying the interactivity-related content, the interactivity-related content comprising content that is unrelated to media content selection;
• and
• present, by the DASH aware application, the interactivity-related content via one or more user interfaces of the client device.
