BROADBAND VIDEO WITH SYNCHRONIZED HIGHLIGHT SIGNALS

摘要

A broadband video layer is integrated with a separately encoded highlight layer configured for presentation in a first window of a video display. One or more visible objects in the video layer are associated with corresponding fitted highlight shapes in the highlight layer. Appearance of the shape object in the video layer is synchronized to appearance of an associated highlight shape to define highlight events. A context may be defined for each highlight event. Occurrence of highlight events may be represented by icons or markers in a video progress bar. Contextual information may be presented in a second window synchronized with the highlight events.
