Abstract
Methods, systems, and computer readable media described herein may facilitate the detection and use of stitch points during trickplay navigation of a content stream. A multimedia device may automatically detect stitch points in a transport stream based upon PTS (presentation time stamp) discontinuities. The multimedia device may generate a slot table that organizes the frames of a piece of content into segments having sequential or linear PTS values. The multimedia device may compare a target PTS to the various PTS ranges of the slot table to identify a region to be searched for a metadata index associated with the target PTS. Once the target PTS is mapped to the appropriate metadata index, the multimedia device may fetch the appropriate frame for presentation.
