Watermarks in video signals or the accompanying audio track are used to associate video objects in a video sequence with object specific actions or information. A video object refers to a spatial and temporal portion of a video signal that depicts a recognizable object, such as a character, prop, graphic, etc. Each frame of a video signal may have one or more video objects. The auxiliary information is embedded in video or audio signals using "steganographic" methods, such as digital watermarks. By encoding object specific information into video or an accompanying audio track, the watermarks transform video objects into "watermark enabled" video objects that provide information, actions or links to additional information or actions during playback of a video or audio-visual program. A similar concept may be applied to audio objects, i.e. portions of audio that are attributable to a particular speaker, character, instrument, artist, etc.
1. A method for encoding substantially imperceptible auxiliary information into a video signal including at least one video object, the method comprising:steganographically encoding object specific information about the video object into the video signal; and associating the object specific informat
1. A method for encoding substantially imperceptible auxiliary information into a video signal including at least one video object, the method comprising:steganographically encoding object specific information about the video object into the video signal; and associating the object specific information with an action, where the action is performed in response to user selection of the video object through a user interface while the video signal is playing.
