Abstract:
1. A method at least partially implemented by a computer, the method comprising: receiving a user selection to switch from a first timeline-altered media stream to a second timeline-altered media stream; accessing a time-compressed stream object corresponding to a data unit, currently being rendered, of the first timeline-altered media stream; identifying, from the time-compressed stream object, a presentation time of a primary media stream whose timeline has not been altered, the presentation time indicates when the data unit of the first timeline-altered media stream is to be rendered, the presentation time being independent of a delivery time that indicates when the data unit is to be delivered to a rendering client; accessing an index table to identify an offset into the second timeline altered stream corresponding to the presentation time of the primary media stream; and rendering or streaming the second timeline-altered media stream beginning at the location identified by the offset to present the second timeline-altered media stream to a user.
