Abstract:
An EPG retrieval system includes a data server, a client, and a dictionary database. The data server stores program information of an EPG. The client includes an access unit for accessing the data server, and an input unit for inputting a retrieval keyword for performing retrieval on the program information. The dictionary database stores retrieval keywords and keywords relevant to the retrieval keywords. The client inputs an arbitrary keyword, and extracts keywords relevant to the input keyword. The extracted keywords and the input keyword are used to perform retrieval on the program information.
