SYSTEM AND METHOD FOR CHANGING CHANNEL IN INTERNET PROTOCOL TELEVISION

摘要

PURPOSE: A channel converting method in an IPTV using preference channel information and a system performing the same are provided to minimize channel zapping time by using the preference channel information of the user. CONSTITUTION: An HG(home gateway)(300) transmits broadcasting data transmitted from a main channel, which a user terminal(100) selects, to the user terminal. The HG joins a candidate channel by using a candidate channel table. If the user terminal connects a main channel during channel maintaining time, the HG releases the candidate channel. The HG confirms the time when the transmission of broadcasting data is completed and rejoins the released candidate channel.
