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.

Abstract: Various implementations described herein are directed to technologies for providing uninterrupted playback of a content recording on a set top box during head end failures. The set top box detects a head end failure. An unavailability mode is entered during the detected head end failure. A head end recovery is detected. The unavailability mode is exited. A content unavailability skipper associated with the recorded content is updated. The content unavailability skipper includes instructions for playback of the recorded content.
