A system includes additional information (18) together with a video stream, where the additional information (18) is related to at least one of the frames (16). Preferably the additional information (18) is related to an object (17a, 17b) within the frame (16). A receiver (82) receives the video and additional information (18) and decodes the video in the same manner independently of whether the additional information (18) is provided. The additional information (18) is selectively presented to a viewer (238) at approximately the time of receiving the frames (16). The system may also present information to a viewer (238) from a unitary file (232,332) containing an image and additional information (18) associated with the image. A selection mechanism permits the selection of objects (17a, 17b) in the image for which the additional information (18) is related thereto. A presentation mechanism provides the additional information (18) to a viewer (238) in response to selecting the object (17a, 17b).
