A system includes additional information together with a video stream, where the additional information is related to at least one of the frames. Preferably the additional information is related to an object within the frame. A receiver receives the video and additional information and decodes the video in the same manner independently of whether the additional information is provided. The additional information is selectively presented to a viewer at approximately the time of receiving the frames. The system may also present information to a viewer from a unitary file containing an image and additional information associated with the image. A selection mechanism permits the selection of objects in the image for which the additional information is related thereto. A presentation mechanism provides the additional information to a viewer in response to selecting the object.
