The invention discloses a method for providing value-added services in an IPTV system, wherein a value added service or a value added service directory is associated with the content provided by IPTV, and a user terminal initiates a request for the value-added service according to the association information. Based on the number of associated value-added services, a value-added service may correspond to a selection ID of the user terminal, may exist in a value-added service root directory associated with the corresponding content, or may exist in a category set in the form of a multi-level directory and the user terminal requests to obtain the link information of the actual value-added service by selecting the directory level by level. The invention also provides an IPTV system, and an IPTV application system and an IPTV user terminal applicable to the IPTV system. The invention allows end users to obtain value-added service information associated with IPTV audio/video programs in real time when using these programs, and thus realizes good interactions between users and played contents.
