Abstract

The proposed invention allows for the creation and distribution of video which has been edited to allow multiple viewing paths through the video. Meta-data associated with the video defines multiple "video depths" or video detail layers which a viewer may choose, from a synopsis or highlights, to the full video with all scenes and details included.

Variable Depth Video Distribution

Currently, video based media is generally authored in a finite, linear fashion by a content creator. When the audience views this video it must be played in a linear fashion, exactly as it has been authored, with the level of depth and detail of the video determined by the content creator. The current drawback of this method is that the content audience has no option of tailoring the media experience to their level of interest. Content providers also have no way to stitch additional sequences of video for future expansion without reauthoring and redistributing the entire video.

This invention describes a method for dynamically adjusting the length and detail of a video. When a content creator is authoring a video, different scenes within the timeline would be marked with metadata for the class or detail level identifier of videoclip or scene. When a user chooses to watch the video, a choice is given, allowing the user to choose different levels of detail, and subsequently video length, before starting the video. A video player or, video server, would be configured to understand this new type of video metadata and automatically play and skip segments as defined by the level of detail chosen. Rather than simply playing a video from start to finish, and perhaps fast forwarding to reduce the overall play length, a user may simply choose a level of detail in the beginning and have the video play through, automatically skipping segments not included in the chosen level of detail. This method offers advantages to users by providing the ability to tailor the viewing experience to the amount of interest a user has or the amount of time a user has. It also offers advantages to the content creator by being able to easily create multiple versions of the video content through tagging and metadata. This opens up the potential of reaching a wider variety of audiences without having to edit multiple version of a video for separate distribution.

The method for implementing this invention begins during content creation. While a video is being edited, scenes are marked with metadata and are assigned a level of detail or content descriptor indicator. This process may involve more editi...
