A device contains a plurality of prestored program clips corresponding to portions of program information for presentation to a user. A comparator (40) compares the program clips with program information and causes selection of an alternate program in response to a match. In one embodiment, the program information corresponds to a television program and program clip corresponds to a video frame at the beginning of an undesirable commercial, resulting in a television that automatically selects an alternate program, in response to an original program having an undesirable commercial. After a predetermined time associated with the video clip the television automatically returns to the original program. The invention also enables creation of new program clips based upon received program information. |
