Patent ID: 7917925

Claim:
A method for automatically extracting data identifying a broadcast A/V program from received broadcast data, the method comprising: measuring for each of a plurality of channels a transmission signal quality caused by signal disturbances; storing for each of the plurality of channels an indication of the measured transmission signal quality; receiving user input defining a first program; analyzing an electronic program schedule according to the first program; determining that the first program is scheduled for future broadcast; determining at least program name and broadcast channel of the first program, and the stored transmission signal quality of the broadcast channel of the first program; determining broadcast start time and end time, or determining broadcast duration of the first program; automatically detecting that a second program is scheduled for future broadcast, wherein the second program corresponds to the first program and has the same content as the first program, but has a different broadcast start time, end time or duration, and a different broadcast channel, wherein the stored transmission signal quality of the broadcast channel of the second program is higher than the stored transmission signal quality of the broadcast channel of the first program; displaying at least the program name, broadcast channel, start time, end time or duration of the first program, and an indication indicating that the second program was detected; automatically detecting which of the program instances displayed in the menu has an advantage or disadvantage regarding the determined broadcast channel or duration according to predefined criteria, wherein the predefined criteria include higher transmission signal quality and/or shorter duration; and indicating in the display the detected program instance that has an advantage as preferable, or indicating in the display the detected program instance that has a disadvantage as not preferable, wherein a criterion for a preferable program is better reception quality of the channel according to said stored transmission quality indication.
