    摘要: A system and method of occlusionless virtual insertion is disclosed that uses an animation of the image. The animation has a full image frame, a null frame, and a number of intervening video frames. When the animation is run, the image appears to be physically moved behind an edge of the animation video frames. An event video-stream is duplicated, and the duplicate delayed to provide a delayed event video-stream. The animation, stopped at the full image frame, is mixed into the delayed event video-stream steam at a selected location using video match moving algorithms. The resultant video-stream is broadcast. The un-delayed, event video-stream is monitored in the region corresponding to where the virtual insertion is occurring in the delayed event video-stream. When this corresponding region begins to become occluded by a foreground object, the animation is triggered. As the time delay of the delayed event video-stream equals the time it takes the animation to run from the full image frame to the null frame, when the foreground object moves into the insertion region in the delayed event video-stream there is no inserted image to occlude it. To the viewer, it appears as if the image is on a movable sign, and just happened to be translated out of view before the object of interest moved into the region.

    摘要: A computer implemented method enables smooth transition of video playback with page flip action within a digital magazine. The method comprises steps of monitoring a user's interactions with a video content item displayed on a current page of the digital magazine. Upon detecting a user flipping the current page to a next page, the video content item is paused, a graphics resource used for rending the video content item is disabled and a current video frame of the video content item is captured. In response to the user flipping the current page to the next page, the graphics resource is enabled for rending the page flip action, a modified current page with portions of the next page are gradually displayed to the user, while the captured video frame is continuously displayed on the current page until the page flip action is finished.
