A transmitter (1112) transmits video and enhanced content to a receiver (1114) for showing on a display (1116), while synchronism can be provided between the content and video (1118) and video may be stored (1120). The enhanced content may be replaced if it was previously activated during the original play or the original video information may be played, while the user can select viewing of the enhanced content during the replay. Independent claims are included for a medium storing program instructions and for a system. |
