Broadcast program information search system and method

摘要

A content program information search system and method is described. The system comprises a digital signal receiver for detecting and displaying a content signal and/or detailed content information for one or more search terms from a digital signal transmitted from a transmitter; and a server having a database for storing search terms inputted from external devices, the inputted search terms being stored by order of priority based for example on search frequency, such that the server extracts and transmits to the transmitter search terms from the first database, and the digital signal receiver displays according to the order of priority at least one search term transmitted from the transmitter. The viewer thus has search terms of high search frequency to enable the viewer to rapidly and easily search for information on a desired content program.
