Abstract
A video presentation system which easily and economically realizes subject-service linkage in a video image displayed on its screen. The system includes a video display for displaying video data containing a subject with an identifier on a display unit, an identifier recognition unit for recognizing the identifier displayed on the display unit, and a data storing unit for storing the video data and various data associated with the identifier. The system further includes a data management means for obtaining data associated with the recognized identifier from the data storing unit and sending the data to the video display. When the user selects the identifier, the identifier recognition unit recognizes the identifier and the data management unit obtains data associated with the identifier from the data storing unit and outputs to the display.
