METHODS AND APPARATUS FOR TRANSMITTING AND RECEIVING INTERACTIVE SERVICE USING UBIQUITOUS SERVER AND UBIQUITOUS TERMINAL ON DIGITAL CABLE BROADCASTING SYSTEM

摘要

PURPOSE: A method and device for transmitting and receiving an interactive service using a ubiquitous server in a digital cable broadcasting and a ubiquitous terminal on digital cable broadcasting system are provided to reduce the need of a TS(Transport Stream) packetizing process for transmitting a channel in a bandwidth. CONSTITUTION: A receiving unit displays an event trigger if an interactive service content related to a receiving channel exists(S10020,S10030). According to the request of a viewer, the receiving unit transmits the normal service enable confirmation request of corresponding content(S10040,S10050). If the content is serviced normally, the receiving unit received content data. The receiving unit performs the received content data(S10060).
