Abstract
Upon receiving a continuous presence video image, an endpoint of a videoconference may identify its self image and replace the self image with other video data, including an alternate video image from another endpoint or a background color. Embedded markers may be placed in a continuous presence video image corresponding to the endpoint. The embedded markers identify the location of the self image of the endpoint in the continuous presence video image. The embedded markers may be inserted by the endpoint or a multipoint control unit serving the endpoint.
Claims20
A method that identifies a self image embedded in a continuous presence video image frame, comprising:
- identifying an embedded marker in the continuous presence video image frame;
- and
- calculating a location of the self image in the continuous presence video image frame responsive to the embedded marker.
A method that removes a self image from a continuous presence video image, comprising:
- calculating a location of the self image in the continuous presence video image, comprising:
- identifying an embedded marker in the continuous presence video image;
- and
- calculating the location of the self image in the continuous presence video image responsive to the embedded marker;
- and
- replacing the self image in the continuous presence video image with other video data.
An apparatus that identifies a self image of an endpoint that participates in a continuous presence video conference, comprising:
- an embedded marker embedder, that embeds an embedded marker in a video image associated with the endpoint, and sends the video image with the embedded marker toward a multipoint control unit that controls the continuous presence video conference;
- and
- an embedded marker identifier, that identifies the embedded marker in a continuous presence video image and calculates a location of the self image in the continuous presence video image.
