Benefits of technology

[0013] The present invention provides a method and apparatus for controlling the operation of a video recording and playback device so as to automatically eliminate commercial messages during playback of a recorded television signal.

Problems solved by technology

Such systems are claimed to be relatively effective for eliminating commercial messages, but suffer certain drawbacks.
In this regard, program material immediately following a commercial break is irretrievably lost since the VCR is held in the “pause” mode for a predetermined period of time (30 to 60 seconds or more) following each break in the television signal.
Furthermore, additional program material may be irretrievably lost if the timing circuit is falsely triggered, such as by a fade between scenes in the program.
This approach solves the problem of losing a fixed amount of program material if a VCR pause if falsely triggered, but it is still susceptible to misclassification.
These systems permit an editing decision to be made after an entire commercial has been aired; however, as with the other systems previously described, program material is still irretrievably lost if there is a false detection of a commercial.
Furthermore, the frequent rewinding of the tape during long commercial breaks accelerates the wear of the VCR tape transport mechanism as well as the tape itself.
Prior art automatic systems do not examine detected events in the full context of surrounding events.
When done during the recording process, such misclassification will cause portions of program material to be irretrievably lost.

Embodiment Construction

[0032] In the following description, for purposes of explanation and not limitation, specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known methods, devices and circuits are omitted so as to not obscure the description of the present invention with unnecessary detail.

[0033] U.S. Pat. No. 5,333,091 discloses a control unit that is coupled between a conventional VCR and a conventional television receiver / monitor. This “stand alone” control unit processes the video signal prior to being recorded to detect events within the signal and to modulate the recorded signal with a time code. The spacing and duration of the detected events is analyzed to classify the video signal between events as either program material or commercial ...

Abstract

A video recording and playback device (10) incorporates a processor (114) for processing the video signal to detect the presence of commercial messages. Video and audio event detectors (102, 104) detect the presence of events in the signal as it is recorded. The timing relationship of the detected events is analyzed to classify the video segments between events as program material or as commercial messages. After a program is recorded, control marks are generated (132) to indicate the beginning and end of commercial groups so that they will be skipped during subsequent replay of the recorded program.
