摘要:
A system and method which mixes images, such as an advertisement, with a video stream of action occurring within a relatively unchanging space, such as a playing field, is disclosed. The system utilizes a model of the background space to change the video stream so as to include the image at some location within the background space. It includes a video frame grabber (10) and an image implantation system (14). The frame grabber (10) grabs a single frame of the video signal at one time. The image implantation system (14) typically implants the grabbed image into the frame onto a predefined portion of a preselected one of the surfaces of the background space if the portion is shown in the frame.

A method and system for orienting a frame viewing an arena in which action occurs is provided. The orientation system includes a background topology graph, a graph creator and a graph correlator. The background topology graph graphs the relationships of the background objects of the arena with each other, wherein the relationships are those which change minimally from view to view of the arena. The graph creator creates a frame topology graph of relationships of segments of the frame. The graph correlator correlates the frame topology graph with the background topology graph to determine which objects of the arena, if any, are represented by segments of the frame.

A method and system for personalizing images inserted into a video stream, provided by a video service (11) to each of its clients (12) according to a priori individual knowledge of its clients. The present invention generates a user profile (10) from video sequences selected by the user from a video server (11) having a plurality of video sequences stored therein. The selected video sequence is personalized according to the user profile, for transmission to the user (12).
