  • Patent number: 7872691
    Abstract: A method and system are provided for allowing channel surfing during the presentation of a commercial broadcast by returning the viewer to the desired program channel after the commercial broadcast has concluded. When a commercial broadcast is received that interrupts the presentation of a viewer's desired programming, channel surfing is facilitated based on increased audio volume levels broadcast with the commercial broadcast. During channel surfing, the present audio level of the primary channel presenting the undesired commercial broadcast is monitored. If the audio volume level drops below the level of the commercial broadcast or returns to the level set by the viewer for the desired program prior to receipt of the commercial broadcast, the desired program channel may be reselected to return the viewer to her desired program channel. The viewer may be notified that the commercial broadcast has ended prior to reselection of the desired program channel.

  • Patent number: 6100941
    Abstract: A commercial detection apparatus includes a frame grab thread which acquires frames from an input data stream to be analyzed by a cut detector thread and a filter thread. A commercial detection thread determines whether a commercial has occurred from data created by the cut detector thread and the filter thread stored in a memory. A factor used by the commercial detection thread is whether a black frame has occurred. The input data stream is divided into a plurality of regions and then a maximum and minimum value for a section of these regions is determined and compared to one another. If the maximum and minimum values are close enough, and the maximum value is below a threshold, then the frame is deemed to be black.

  • Patent number: 5999689
    Abstract: The method and apparatus operates in a VCR to identify selected broadcast segments, such as commercial advertisements, of a television signal in real-time for the purpose of suspending recording of the television signal during each unwanted segment. A signature pattern associated with each segment of the television signal is detected and compared to stored signature patterns representative of selected segments such as commercial advertisement segments. If the signature pattern matches one of the stored signature patterns, the segment is thereby immediately identified as being one of the selected segments and is processed in real-time to suspend recording during the segment. If the signature pattern of the segment does not match any of the stored signature patterns, the segment is analyzed to determine whether the segment is nevertheless a selected segment and, if so, its signature pattern is stored along with the stored signature patterns.

  • Patent number: 5999688
    Abstract: A video playback device includes video and audio event detectors which detect the presence of events in the video signal as it is played. When the viewer commands the device to skip past a portion of a recorded program, a processor monitors the detected events to locate an event corresponding to the beginning of a next program segment. The device then returns to that location and begins normal play. Alternatively, the viewer may manually terminate the skipping process, at which time the device automatically returns to the location of the most recently detected event.
