Method for providing electronic program guide information and system thereof

An EPG information providing system comprising:

• a tuner control unit outputting a channel selection signal;
• a tuner sequentially selecting a reception channel from a plurality of channels in response to the channel selection signal and receiving a transport stream which is input via each sequentially-changed channel and includes EPG information;
• an EPG information extraction module connected to the tuner, extracting the EPG information from the transport stream input via the each sequentially- changed channel;
• and a storage device receiving and storing the EPG information extracted by the EPG information extraction module.

An EPG information providing method comprising:

• receiving EPG information extracted from a transport stream and storing the
• EPG information in database, using a first server;
• generating a keyword on the basis of the received EPG information and storing the keyword in the database, using the first server;
• transmitting the keyword to a predetermined search server, using the first server;
• and receiving a result of a search performed by the search server and extracting additional information from the search result, using the first server.

An EPG information providing system comprising:

• a database;
• a keyword management module receiving EPG information extracted from a transport stream, storing the EPG information in the database, extracting a keyword on the basis of the EPG information, and storing the extracted keyword in the database;
• an additional information generation module transmitting the extracted keyword to a predetermined search server, receiving a result of search performed by the search server, and extracting additional information from the search result;
• and a network module transmitting at least one of the EPG information stored in the database and the additional information to a user set top box.
