Abstract: In current systems, augmented reality graphics is generated at a central broadcast facility or studio where it is combined with the video that is transmitted to subscribers. By contrast, in the described system, the studio does not generate the graphics, but transmits video together with real-time metadata to the end-user set-top device. The end-user device generates the augmented reality graphics, using the metadata to determine positional and other parameters for displaying the graphics. Shifting the generation of augmented reality graphics to the consumer level facilitates end-user customization and individualized targeting of information by a broadcaster or advertiser.

Abstract: A method and system are presented for use in real-time insertion of visual effects in a video stream. At least one reference image is used that contains a region of interest, which is to be involved in the video stream. the reference image is processed by defining a set of at least a few reference features therein, and inserting the visual effects into the reference image with a desired orientation of the visual effects with respect to the region of interest in the reference image. Successive video frames are grabbed in a sequence of a few video frames, and at least one of video frames is used as at least one snapshot image. The snapshot image(s) is/are process by selecting therein at least two from the reference features and determining a reference transformation between the snapshot image and the reference image. Independently of this processing of the snapshot image, the snapshot image and other video frames are processed to determine a sequence of transformations between them.
