Abstract
Ancillary information associated with one or more images embedded in a digital broadcast data stream may be accessed by a digital broadcast receiving device. The device may include a receiver unit, a processor, and a memory. The processor may execute program instructions to access the ancillary information. Control data may be associated with one or more visual components of one or more video images. The control data and images may be combined into a digital broadcast data stream. The device may receive the images and control data. The images may be presented on a display device. The receiving device may use the control data to present or store a perceptible indication that ancillary information is associated with the visual components in conjunction with presenting the images. The device may use the control data to present or store the ancillary information in response to an input signal.
