A method and system to automatically detect and isolate segments of interest from sports programs is provided. Accordingly, the method includes the steps of: segmenting incoming video programs into a plurality of segments; detecting a slow moving object between the frames; computing the corresponding gravity level of the detected segments representing the slow moving object; and, comparing the computed gravity level to a predetermined threshold. The system includes a segmentation circuit for segmenting each frame of incoming video programs into a plurality of segments, and a motion detection circuit for detecting the slow moving object between successive frames and for determining the gravity level corresponding to the slow moving object.

2. Description of the Related Art
FIG. 1 illustrates an exemplary video detection/recording device and a television set according to an embodiment of the present invention;
FIG. 2 illustrates a simplified block diagram of the detection device according to an embodiment of the present invention;
FIG. 3 is a flow diagram illustrating the operation of the detection device according to an embodiment of the present invention;
In the following description, for purposes of explanation rather than limitation, specific details are set forth such as the particular architecture, interfaces, techniques, etc., in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments which depart from these specific details. Moreover, for the purpose of clarity, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
FIG. 1 illustrates an exemplary video detection/recording device 10 and a television set 2 according to the embodiment of the present invention. The video detection/recording device 10 is adapted to receive a stream of video signals from a variety of sources, including cable service provider, digital high definition television (HDTV) and/or digital standard definition television (SDTV) signals, a satellite dish, a conventional RF broadcast, an Internet connection, or another storage devices, such as a VHS player or DVD player. According to the embodiment of the present invention, the video detection/recording device 10 detects the incoming video signals (i.e., sports programs) for any slow-motion frames and stores a summary of slow-motion segments in a storage medium within or connected to the video detection/recording device 10. During a play mode, the video detection/recording device 10 retrieves the stored summary of the sports highlights from the storage medium and replays it at normal speed via the television set 2.
FIG. 2 illustrates an exemplary video detection/recording device 10 in greater detail according to the embodiment of the present invention. The detection device 10 includes an input interface (i.e., IR sensor) 12, MPEG-2 encoder 14, hard disk drive 16, MPEG-2 decoder, controller 20, slow motion detector 22, video processor 24, and memory 26, and playback section 28. It should be noted that MPEG encoder/decoder may comply with other MPEG standards, i.e., MPEG-1, MPEG-2, MPEG-4, and MPEG-7. The controller 20 overseas the overall operation of the detection device 10, including a detection mode, record mode, play mode, and other modes that are common in a video recorder/player.
