<p>A system and method are disclosed for preloading interactive content before it is to be displayed, thereby avoiding any unwanted delays due to download times. According to the invention, ITV data is embedded (40) into the signal at some predetermined time before the corresponding segment will be broadcast. The ITV data is received by the ITV receiver (42), which then access an interactive site (web site or other server) and makes a request for the interactive content (48).
