Abstract
Broadcast receiving devices usually have access to an electronic program schedule or EPG. Since often the same audio/video program is broadcasted more than once within a short time range on the same channel, or simultaneously on another channel, a method is provided for notifying this fact to the user. According to the invention, a method for automatically extracting data identifying a broadcast A/V program from received broadcast data includes the steps of receiving user input defining a first program, analyzing an EPG, determining broadcast data of the first program, automatically detecting that an identical second program is scheduled for broadcast, and displaying an indication to the user indicating that the second program was detected. If e.g. the same program is broadcasted at different times or channels with different amount of commercial interruptions, the user may select the instance with less commercials for viewing or recording.
