  • Publication number: 20060026628
    Abstract: A method and apparatus inserts virtual advertisements or other virtual contents into a sequence of frames of a video presentation by performing real-time content-based video frame processing to identify suitable locations in the video for implantation. Such locations correspond to both the temporal segments within the video presentation and the regions within an image frame that are commonly considered to be of lesser relevance to the viewers of the video presentation. This invention presents a method and apparatus that allows a non-intrusive means to incorporate additional virtual content into a video presentation, facilitating an additional channel of communications to enhance greater video interactivity.
