A system, method and apparatus for displaying real time auxiliary information from a secondary source or input signal in combination with a program from a separate primary source. The auxiliary information (e.g. textual, graphical or video images) is selectable and is received through a second, integral or stand-alone tuner. The selected information can be displayed (1) continuously, (2) at predefined regular intervals, or (3) as the (defined) event(s) occur either in real time or in memory to provide a short delay time. The auxiliary information may be part of a currently transmitted data stream or as a separate data stream. |
