A scoreboard is a large board for publicly displaying the score in a game or match. 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. A dot matrix is an array of dots used to generate characters, symbols and images. ...

Technology Prior to the 1980s most electronic scoreboards were electro-mechanical. They contained relays or stepping switches controlling digits consisting of incandescent light bulbs. Beginning in the 1980s, advances in solid state electronics permitted major improvements in scoreboard technology. 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 100,000 hours before having to be replaced. 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 AC wires providing power to the scoreboard or through the air. Powerline modems permit the digital control signals to be sent over the AC power line. The most common method of sending digital data over power lines at rates less than 2400 bits per second is called frequency shift keying (FSK). Two radio frequencies represent binary 0 and 1. Radio transmission usually also 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 North American football 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. Football scoreboards may include a horn to signal the end of a quarter, but they are not used in larger venues.

Basketball 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 1989), and NCAA (since 2001). 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 (not used in FIBA play), and possession (with a separate possession arrow display at half-court). 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. Image File history File links 2241-PPF5-PNP15. ...

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. Now in high school basketball it is mandatory for high schools to have a clock that counts down in tenths.
Since 1991, 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. However, an exemption to the rule was permitted in 1992 when the Anaheim Convention Center was permitted to host a playoff game because the Los Angeles Sports Arena, the home of the Clippers, was unable to be used because of the Rodney King riots in Los Angeles. The Convention Center did not have a clock in tenths or a game clock duplicate readout 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. The 1992 Los Angeles riots, also known as the Rodney King uprising or the Rodney King riots, were sparked on April 29, 1992 when a predominately white jury acquitted four police officers accused in the videotaped beating of black motorist Rodney King, after he fled from police. ...
After various arenas, from fan requests, installed three-sided game shot clocks, the NBA instituted a new game shot clock rule in 2002, requiring specific visibility of the game and shot clock time for replay purposes. FIBA installed a similar three-sided rule in 2004. The rule was further changed in 2005 by a new Daktronics see-through model (one on top of the basket, one on the end of the basket unit); that model is now used in FedExForum (where the unit was tested in 2004-05), Wachovia Center and the newly built Charlotte Bobcats Arena (both installed in 2005), and the TD Banknorth Garden and Philips Arena (both installed for the 2006-07 season). [[ Daktronics]] recently introduced a technology called ColorSmart. This technology changes the LED color based on the game information. For example when a team is winning the score is in green and when the team is losing the score is in red. Unfortunately though this feature isn't permitted in FIBA, NBA, NCAA, or High School basketball because the clock must be kept the same color without change. This rule was introduced in 1994 when Spectrum Scoreboards created a similar concept. FedExForum is one of the most unique arenas in the NBA. It officially opened in September of 2004, after much debate and also a alberta clipper wind storm in Jully 2003 that nearly brought the crains building the arena down on famed Beal street. ...

Baseball
A large scoreboard used for Major League Baseball at Jacobs Field. This scoreboard is in full color and has a large video screen integrated.
 Hockey scoreboard in Helsinki Ice Hall. 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 and the time of day, and 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 too 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. (Examples of the program are DakStats and The Automated Scorebook) ImageMetadata File history File links Download high resolution version (1024x768, 751 KB) File links The following pages link to this file: Cleveland, Ohio ...
