Scoreboard - Wikipedia, the free encyclopedia. A scoreboard is a large board for publicly displaying the score in a game.[citation needed] Most levels of sport from high school and above use at least one scoreboard for keeping score, measuring time, and displaying statistics.
Scoreboards in the past used a mechanical clock and numeral cards to display the score. When a point was made, a person would put the appropriate digits on a hook.
Most modern scoreboards use electromechanical or electronic means of displaying the score. In these, digits are often composed of large dot- matrix or seven- segment displays made of incandescent bulbs, light- emitting diodes, or electromechanical flip segments. An official or neutral person will operate the scoreboard, using a control panel. Technology[edit]Wrigley Field uses a hand operated scoreboard, but added a video board at the bottom of it in 2. Prior to the 1. 98. They contained relays or stepping switches controlling digits consisting of incandescent light bulbs.
Beginning in the 1. High power semiconductors such as thyristors and transistors replaced mechanical relays, light- emitting diodes first replaced light bulbs for indoor scoreboards and then, as their brightness increased, outdoor scoreboards. Light- emitting diodes last many times as long as light bulbs, are not subject to breakage, and are much more efficient at converting electrical energy to light. The newest light emitting diodes can last up to 1.
Advances in large- scale integrated circuits permitted the introduction of computer control. This also made it cost effective to send the signals that control the operation of the scoreboard either through the existing ACwires providing power to the scoreboard or through the air. Powerlinemodems permit the digital control signals to be sent over the ACpower lines. The most common method of sending digital data over power lines at rates less than 2. FSK). Two radio frequencies represent binary 0 and 1.
Radio transmission such as FSK sends data digitally. Until recently radio transmission was subject to short range and interference by other radio sources.
A fairly recent technology called spread spectrum permits much more robust radio control of scoreboards. Spread spectrum, like the name implies, distributes the signal over a wide portion of the radio spectrum. This helps the signal resist interference which is usually confined to a narrow frequency band.
Scoreboards in various sports[edit]In both the United States and Canadian football codes, the minimum details displayed are the time and score of both teams. A typical high school scoreboard will additionally display the down, the yardage of the line of scrimmage, the yards to go until a first down, the team with the possession (usually signified with the outline of a football in lights next to the possessing team's score) and the quarter. Higher levels will also include play clocks and the number of time outs left for each team. American football scoreboards may include a horn to signal the end of a quarter, but they are not used in larger venues. In those cases, the referee or public address announcer denotes the termination of a quarter vocally via the PA system; formerly quarter ends were denoted with the firing of a starting pistol in the era before digital timing.
Basketball[edit]A basketball scoreboard will at the minimum display the time left in the period and both team's scores. The last minute of each quarter is usually displayed with tenths of a second, which is required in FIBA, NBA (since 1. NCAA (since 2. 00. Most high school scoreboards also include a display of the number of team fouls, the number of the last player to commit a personal foul (with the total number of personal fouls for that player), the period, and indicators of which team is in the team foul penalty situation, and possession (with a separate possession arrow display at half- court; not used in the NBA). College basketball scoreboards include shot clocks and the number of time outs left for each team. Larger scoreboards include statistics on the players in the game. Basketball scoreboards must include a horn or buzzer to signal the end of a period, fouls, and substitutions; the shot clocks have their own buzzer system to avert any confusion with the game clock system.
In some multipurpose venues where ice hockey and basketball are played, the scoreboard unit which shows penalties will be used to display the player on the court, number of fouls, and points scored in the game. The team fouls are usually placed in the same position as shots on goal in hockey games. In some university arenas, the scorer's table, which has traditionally been used for displaying physically scrolling advertising boards along its face, may also feature either a traditional mechanical scoreboard, or a scoreboard display within a LED display on the front of the table which also functions with virtual scrolling advertisements. Since 1. 99. 1, the NBA has mandated that each shot clock carry a duplicate readout of the time left in the period in addition to the shot time. Since 2. 01. 1, the shot clock also shows tenths of a second past five seconds left on the shot clock. Many college and even some high- school shot clocks (in states where a shot- clock rule is in effect for high- school basketball) now also include a game timer.
Three- sided game shot clocks became a trend in the 1. NBA Playoffs, the NBA instituted a new game shot clock rule in 2. FIBA installed a similar three- sided rule in 2.

The rule was further changed in 2. Daktronics see- through model (one on top of the basket, one on the end of the basket unit) that has gained popularity as many OES and Daktronics venues have adopted the system. Daktronics recently introduced a technology called Color. Smart, which denotes the trailing team's score numbers with red lighting, while the leading team is in green. However this technology has yet to be utilized in a game settings as the bylaws of the major basketball sanctioning bodies and many of the high school athletic bodies decree that both scores must display in the same color; the rule came into effect in 1. Spectrum Scoreboards introduced an earlier version of the concept. This is used almost exclusively in recreation leagues.
Baseball[edit]For baseball the scoreboard will at the minimum show both team scores, as well as the current inning. In addition the number of balls, strikes and outs is represented by digits or individual lights. Larger scoreboards offer an inning- by- inning breakdown of the scores, hits, errors, pitch count and the time of day.

There may also be another display either separate or combined with the scoreboard listing the radar gun reading of the last pitch thrown in miles per hour. Almost all Major League facilities have a video board as a scoreboard or a matrix display. Usually these scoreboards are controlled via programs that keep statistics and not just the score. Usually the official scorer will operate this program. Then all the information the official scorer will enter will automatically be outputted to the scoreboard. Currently, the largest scoreboards are located at Progressive Field in Cleveland, Ohio, and Kansas City, Missouri's Kauffman Stadium.
There is also a very large scoreboard at Citizens Bank Park home of the Philadelphia Phillies. Manually operated scoreboards are still found frequently in baseball, particularly at older venues. Well- known examples of manual scoreboards, using numbers painted on metal sheets hung by people working inside the scoreboard, include Fenway Park in Boston and Wrigley Field in Chicago. In some stadiums since 2. LED boards which are the full height of the outfield wall have been installed to either replace a manual scoreboard or enhance an existing wall, are considered in play, and are durably constructed to withstand the impacts of fielders colliding with the wall, along with the impact of a baseball against the panel.
Examples of this type of scoreboard display are seen in Milwaukee's Miller Park, Rogers Centre in Toronto, New Yankee Stadium in The Bronx, and Kauffman Stadium in Kansas City. In all three cases, the walls display the current game state of out- of- town games (often down to pitch count for the current at- bat and runners on base), statistics for the current batter or pitcher, and promotional messages. Cricket[edit]For cricket a scoreboard will as a minimum display the batting team's score, wickets fallen, the opposition's totals. Most county- standard scoreboards will also display each batsman's score, overs remaining, extras, the bowlers currently on and details of the last wicket to fall.
Australian state scoreboards will usually contain more detailed information. Ice hockey scoreboard in Helsinki Ice Hall. Ice hockey[edit]An ice hockey scoreboard will at the minimum display the time left (in North America) or played (in Europe), the number of goals scored by each team as well as any penalties currently being served.
Additional information such as shots on goal may be shown on smaller scoreboards located in the arena. Tenths of a second are usually displayed within the last minute of each period.
In multipurpose arenas, the penalties being served will appear in the multi- purpose panels, used for player statistics in basketball, with shots on goal in the same position as team fouls for basketball. In some arenas the sideboards of the hockey rink feature three or four LED displays the size of one advertising hoarding which will show scoring information and promotional messages, though their limited visibility makes them rarely used.
Motor sports[edit]In auto racing, the scoreboard typically displays the running order of the race, and number of laps completed. Some more complex boards scroll statistics such as average speed, laps behind, and timing reports. All codes of rugby football have a game clock, the number of tries, penalties, field goals and conversions listed.
