Abstract

This invention relates to a server and a set-top box for an interactive TV system, an interactive TV system including the same, a method of changing channels thereof, and a method of transmitting multimedia thereof. More particularly, this invention relates to a server and a set-top box for an interactive TV system, an interactive TV system including the same, a method of changing channels thereof, and a method of transmitting multimedia thereof that include plural channels in addition to a channel currently viewed and that request a selected channel from a server while searching and displaying a correspondent channel if a TV viewer requests a channel change. Therefore, standby time can be removed when a channel is changed in an interactive TV. For this purpose, this invention provides an interactive TV system which is characterized by including: a server that transmits multimedia data; and a set-top box that receives the multimedia data from the server. Here, the server adds to the multimedia data not only a channel currently viewed but also a channel for channel information that includes plural channels near the channel currently viewed. In addition, the server transmits the multimedia data to the set-top box.
