Abstract

A streaming abstraction system is described herein that provides application developers a client software development kit (SDK) on top of which to build smooth streaming solutions. The system reduces development time considerably and abstracts platform specific intricacies and protocol handling on the client. In addition, the streaming abstraction system makes it possible to monetize streaming content with advanced features like advertising and analytics and provides advanced capabilities like multiple camera angles, diagnostics, and error handling. In some embodiments, the streaming abstraction system provides an intermediate layer that operates between an application and an underlying client media platform. The intermediate layer manages smooth streaming protocol handling as well as interactions with the platform-specific runtime.

Claims

1. A computer-implemented method for interaction with an application from a client abstraction layer, the method comprising:

receiving a request to instantiate the client abstraction layer;

receiving a request to set a media source through the abstraction layer, wherein the media source identifies a server from which the abstraction layer can retrieve an identified media presentation;

downloading media associated with the requested media source on behalf of the application;

starting playback of the downloaded media on behalf of the application;

receiving an indication that a user action related to the media playback has occurred; and

modifying the media playback in accordance with the received indication of the user'"'"'s action,

wherein the preceding steps are performed by at least one processor.

2. The method of claim 1 wherein receiving the request to instantiate the client abstraction layer comprises identifying an instance of an object provided by the layer in a web page requested by a client browser.

3. The method of claim 1 wherein receiving the request to set the media source comprises receiving the media source in the request to instantiate the client abstraction layer.

4. The method of claim 1 wherein receiving the request to set the media source comprises receiving the media source from a client application call to a software method provided by the abstraction layer.

5. The method of claim 1 wherein receiving the request to set the media source comprises receiving a path to a manifest used for smooth streaming media.

6. The method of claim 1 further comprising, upon receiving the request to set the media source, sending from the abstraction layer a request to an identified server on behalf of the application to download a smooth streaming manifest for consuming the identified media presentation.

7. The method of claim 1 wherein starting download media comprises performing media setup and retrieval on behalf of the application without the application having to write specific programming code other than invoking the system with the location of the streaming media.

8. The method of claim 1 wherein starting playback of the downloaded media on behalf of the application comprises abstracting knowledge of particular codecs and smooth streaming protocols from the application.

9. The method of claim 1 wherein the abstraction layer provides application programming interfaces to the application for manipulating media to play, pause, and seek within the media presentation.

10. The method of claim 1 wherein receiving the indication of the user action comprises receiving an indication that the user requested to skip to a new location within the media presentation.

11. The method of claim 1 wherein modifying the media playback comprises performing one or more smooth streaming actions within the abstraction layer without input from the application.
