Abstract
Aspects of the present disclosure reduce visual artifacts and provide robust video signals to end-user equipment. According to an aspect, a system includes a splice point controller that analyzes video to detect and compensate for content boundary misalignments. The splice point controller can process video streams by analyzing splice point parameters and/or dynamically updating adjustment values associated with splice points to ensure appropriate transitions from primary content to secondary or alternate content. After determining an adjustment value for a splice point, the splice point controller can provide splice point adjustment feedback to a signal processing engine and/or to a secondary content source as part of synchronizing outputs of a transcoder farm and/or the secondary content source. For example, the splice point controller can operate to align a splice point adjustment value associated with an SCTE-35 descriptor with an actual live splice point time that is included with a live broadcast.
