Description

TV BROADCAST VAN AND PORTABLE REPLAY DEVICE

BACKGROUND OF THE INVENTION This invention relates to reviewing electronic images and other signals.

More particularly, this invention relates to selecting and reviewing signal segments, including for example instant replay images and signals at sports, entertainment, news and other events, and in security systems.

DESCRIPTION OF THE RELEVANT ART The invention of instant replay in 1963 revolutionized the way in which televised events are viewed. At the time, the notion of reviewing a portion of an event, only moments after it occurred, was entirely novel. Instant replay also had dramatic effects on how football games and other sports events are officiated.

The job of football officials, for example, includes making split-second decisions while simultaneously observing players, yard markers, boundaries and the ball.

Occasionally, officials are confronted with difficult calls which would be easier to resolve with benefit of hindsight. Recognizing this, in 1986, major league football organizers adopted the use of instant replay during games as a tool to allow officials to review and correct "hard" or "close" calls. As initially implemented, instant replay did not provide on-field officials with access to instant replay images. Rather, when a call was challenged, an off-field official reviewed available instant replay images of the relevant play, and described the review to on-field officials. The off-field official had access to instant replay images from each of several video cameras covering various angles and aspects of the play, but the on-field officials did not.

Instead of ensuring accuracy and quality of officiating, instant replay did not always resolve disputed calls. Instant replay sometimes also had negative effects on football games. Frequent challenges were made to calls by on-field officials. Lengthy delays, some lasting longer than five minutes, resulted while off-field officials reviewed plays, thereby expanding the duration of games, interrupting team momentum and disrupting mass media coverage. On-field officials were embarrassed when their calls were overturned. Accordingly, in 1991, the pragmatic problems faced by teams, referees, mass media producers and fans led major league football to terminate the use of instant replay during games.

Periodically, however, fans, players, officials, teams and mass media interests urge that instant replay be re-instituted. Today, television producers have integrated instant replay fully into their broadcasts and commentary on football and other sporting events. After a play, remote television viewers are often provided with instant replays from numerous camera angles. In a very real sense, television viewers now have some of the best seats for evaluating whether correct calls have been made. Even fans attending the games can see instant replay on large screen televisions situated around the playing field or on portable receivers they bring to the event. Meanwhile, officials are left to wait until post-game review to determine the accuracy of a call.

Accordingly, there is a need for a system that would provide sports event officials with portable on-field devices having substantial signal storage capacity, quality picture resolution, and zoom and slow-motion playback capabilities that would enable them in nearly real time to review, evaluate and, if necessary, change their judgments and calls. Such devices could also be used to review and evaluate other events, including entertainment and news events, and monitor real-life events and information reports.

Such devices and systems also could be used as security systems at stores, commercial premises and other locations. SUMMARY OF THE INVENTION
