According to the invention, channel surfers are aided by summary frames appearing on the screen along with the regular program. These summary frames are embedded in the broadcast and appear in a small window on the screen at some point in the future as the video is broadcast. The summary frames depict key scenes from the past which aid the viewer in quickly ascertaining the current plot or theme of the video program. In an interactive television environment, a short video segment may be associated with each shot such that when the shot is selected, the past video segment is played in a larger window on the screen complete with sound. Once the segment is viewed, the video program is rejoined in progress with the viewer having a better sense of what is going on in the video. Hence, a when a channel surfer arrives at a new channel, rather than only having what is currently playing to catch the eye, summary frames are also available to catch the surfer's attention and aid in understanding the programming. |

DETAILED DESCRIPTION It is therefore an object of the present invention to provide summary frame windows on the screen of a playing video.
It is yet another object of the present invention to allow a viewer to select one of the summary frames to have a short video clip played on the screen, including the accompanying audio, to get the viewer quickly "up to speed"on programs already in progress.
It is yet another object of the present invention to allow a viewer to quickly jump back to a past segment of a video program to aid in understanding what is presently happening.
According to the invention, various shots or summary frames are selected from a video prior to broadcast.
These summary frames are embedded in the broadcast and appear in a small window on the screen at some point in the future as the video is broadcast.
The summary frames depict key scenes from the past which aid the viewer in quickly ascertaining the current plot or theme of the video program.
In an interactive television environment, a short video segment may be associated with each shot such that when the shot is selected, the past video segment is played in a larger window on the screen complete with sound.
Once the segment is viewed, the video program is rejoined in progress with the viewer having a better sense of what is going on in the video.
Hence, when a channel surfer arrives at a new channel, rather than only having what is currently playing to catch the eye, summary frames are also available to catch the surfer's attention and aid in understanding the programming.
In a television broadcast environment, this invention is particularly helpful in the event a preempting commercial is airing when a particular channel is surfed.
Since the summary frames remain on the screen, the viewer now has a way to quickly determine what program is playing and if it is worth viewing.
Similarly, in the event a program is preempted, for example, for an emergency broadcast or an overtime sports event, summary frames are provided to keep the viewer in touch with the regularly scheduled programming
