Abstract

Systems, methods, apparatuses, and computer readable media may be configured for establishing at least one session for delivery of multimedia. In an aspect, a first transmission of data fragments of a first component and a second transmission of data fragments of a second component may be transmitted and synchronized for presentation. If an inactivity event is detected the session may be maintained while reducing bandwidth consumption.

Claims

1. A method comprising:

establishing a session for delivery of;

a first component of a multimedia content item; and

a second component of the multimedia content item,

wherein the first component and the second component each comprise a different one of video, audio, or data components of the multimedia content item;

providing, during the session, data fragments of the first component synchronized with data fragments of the second component;

determining an inactivity event during the session; and

after determining the inactivity event;

maintaining the session in an active state;

causing delivery of the first component be stopped; and

continuing to provide the second component while delivery of the first component has stopped.

2. The method of claim 1, further comprising:

determining an activity event while the delivery of the first component has stopped; and

after determining the activity event, resuming delivery of the first component.
