Using a remote, a user can send information to the set-top box and based on the connectivity you have set up, this information will be processed locally or remotely and something will happen. Some people have another name that interactive television may go by. This is enhanced television. We think that this is more of an umbrella term applying to every application that goes beyond the common every day television we have had for the last 50 years. In this case, almost every television application is enhanced since almost every television application has closed captioning.
Some people call enhanced television one that has an enhanced online program guide.
This would certainly be nice, but only indirectly relates to multimedia education. We suppose if you could interactively search this guide for educational programs then this might apply. With these devices, you can surf a limited amount of specially prepared Web pages and can access some special image and graphical overlays on some limited number of TV shows which allow you to do things like vote, play games and get additional information about a topic on the TV show. These devices and these possibilities do indicate some possibilities for multimedia education. Clearly getting additional information interactively on a news show or Discover program can be educational.
