METHOD AND SYSTEM FOR ADVERTIZING ON DIGITAL BROADCASTING

摘要

A method and a system for performing AD(ADvertisement) on digital broadcasting are provided to maximize AD effect without giving unpleasant or refusal feeling to a user by playing an AD image or a moving picture in a screen for a channel switching time when the user requests channel switching. A receiving terminal(40) receives/displays digital broadcasting data by IP(Internet Protocol) broadcasting and AD data played for a channel switching time. An application server receives a session setting request for the digital broadcasting from the receiving terminal and transfers the request to an STB(Set-Top Box)(50). An AD server(20) transmits the AD data to the receiving terminal through a separate IP session when the digital broadcasting data transmitted to the receiving terminal from the STB is buffered in the receiving terminal. The receiving terminal includes an AD data query part(46) checking whether the AD or updated data to be received from the AD server is found, an AD data receiver(41), a database(48), a data searching/selecting part(47) searching/selecting the AD data to be displayed for the channel switching time from the database, an AD display information provider, and a packet analyzer(44).
