  • 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.

  • Publication number: 20040222188
    Abstract: A method of cleaning a deposition chamber includes applying an RF power to a first region of a deposition chamber where a metal oxide layer is attached. The metal oxide layer in the first region is thicker than the metal oxide layer existing at a second region of the deposition chamber. The RF power increases a plasma sheath potential in the first region to a value that is greater than that of a plasma sheath potential in the second region. An etching gas is introduced into the deposition chamber to remove the metal oxide layer. The metal oxide layer attached to the deposition chamber may be rapidly removed by the in-situ process without opening of the deposition chamber.
