       BACKGROUND OF THE INVENTION 
       [0005]    1. Field of the Invention 
         [0006]    Many children, high school and University students play sports in the United States and around the world. There are also many city, metro and community leagues of youth and adult games and players. Most sports use some form of scoreboard to keep track of the current status of the game being played. To run a scoreboard, there has to be some form of hardware that serves as the scoreboard controller, which allows a person to input the data. The scoreboard controller could also be considered a source computer system. The present invention discloses a method to accurately convey running clock information from the source computer system to a receiving computer system while using minimal bandwidth.

       BRIEF SUMMARY OF THE INVENTION 
       [0009]    The present invention relates to a method for transferring the status of a source clock from a source computer system to a receiving computer system with a minimal use of bandwidth. A source computer system first sends the status of a clock on the source computer system. The source computer system communicates the clock information using a pair of variables and an optional Boolean variable. The receiving computer system will process the data from the source computer system and display the clock status to a user.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0015]    The invention is carried out as illustrated in  FIGS. 1-4 . The invention is used to communicate the status of a clock that is counting down on a source computer system  100  to a receiving computer system  101  while consuming a relatively low amount of bandwidth. The source computer system  100  sends data to the receiving computer system  101  through a communication protocol. The communication protocol conveys a set of data that includes the amount of time remaining on the clock, whether the clock is running or stopped, and whether any time passed since the data was set. 
         [0016]    The communication protocol can convey this set of data using two primary methods. The first primary method is by using two numeric variables and a Boolean variable. The first numeric variable conveys how much time is remaining on the clock. This first numeric variable can be calculated by converting the time remaining on the source computer system to an integer format. For example, if there were three minutes twenty seconds left on the clock, the first numeric variable would be passed as two hundred seconds. The first numeric variable can be expressed in any format that represents time, though the two most common formats will be seconds and milliseconds. 
         [0017]    Using the first primary method, the second numeric variable conveys an amount of time elapsed since the first numeric variable was a true representation of how much time was remaining on the clock. For example, the source computer system  100  passes a first numeric variable of four hundred seconds but it is three seconds later that the values are transmitted to the receiving computer system  101 . The second numeric variable would then be either three seconds or three thousand milliseconds. Other time units can also be used for the second numeric variable, but again, the most common units will be seconds and milliseconds. This second numeric variable can be used by the receiving computer system  101  to account for this “offset” between when the first numeric variable is set and when it is transmitted and received. The Boolean variable conveys whether the clock is currently running or stopped. Whether the clock is running is critical to the importance of the second numeric variable. That is, if the clock is stopped, it really does not matter how much time has passed since the first numeric variable was an accurate representation, except that the second numeric variable may represent the time passed since the clock was stopped, thereby conveying an accurate history of clock operations. 
         [0018]    The receiving computer system  101  processes the communication protocol by correlating the first numeric variable with an internal clock on the receiving computer system  101 . For example, the receiving computer system  101  may receive a first numeric variable of five hundred seconds and correlate this to 8:15:23 on its internal clock. When the internal clock reads 8:16:23, the receiving computer system  101  will know that one minute, or sixty seconds, has passed, which would mean that this sixty seconds would be subtracted from the five hundred seconds of the first numeric variable to obtain a current value of four hundred forty seconds remaining. These four hundred forty seconds will be converted into a time format that can be displayed to an end user or remote viewer  102 . The most common format would be the minute, second, millisecond (00:00.000) format. 
         [0019]    The receiving computer system  101  would also take into account the second numeric variable if it is not zero when making this calculation to determine how much of an adjustment should be made to the final display. 
         [0020]    For example, if the receiving computer system  101  receives a first variable of five hundred seconds and correlates this to 1:00:15 on an internal clock, and receives a second variable of zero seconds, the receiving computer system  101  will take this into account. When the receiving computer system&#39;s internal clock reaches 1:01:15, with a second numeric variable of zero, the receiving computer system  101  would calculate that sixty seconds has passed and display four hundred forty seconds to the user or remote viewer  102  as 7:20.000. Using these same numbers, but with a second numeric variable of three seconds, the receiving computer system  101  would subtract this three seconds from it&#39;s internal clock to establish a “baseline time” of 1:00:12. The receiving computer system then continuously compares its current internal clock value with the established baseline value of 1:00:12 to determine the amount of time passed since the value was established. When the receiving computer system&#39;s internal clock reaches 1:01:15, this is compared to the baseline value of 1:00:12 to determine that 63 seconds has passed since the value was set. The receiving computer then subtracts 63 seconds from the original 500 value to determine that 437 seconds remain. The receiving computer system then translates this to display 7:17.000. 
         [0021]    The second primary method for the communication protocol to send this data from the source computer system  100  to the receiving computer system  101  is to pass a signed first numeric variable and a second numeric variable and no Boolean variable. 
         [0022]    In the second primary method, the receiving computer system  101  converts the first numeric variable to a time remaining exactly the same way as the first primary method. The receiving computer system  101  also uses the second numeric variable in the exact same way as the first primary method. The only difference in the second primary method is that the sign on the first numeric variable is how the receiving computer system will determine whether the clock is currently running. This can be done with no sign, or a positive sign, indicating that the clock is running, and a negative sign indicating that the clock is stopped. The reverse could also be used, where no sign, or a positive sign indicates the clock is stopped and a negative sign indicating the clock is running. 
         [0023]    There is an additional variation to how data can be passed from the source computer system  100 . Rather than passing the data directly from the source computer system  100  to the receiving computer system  101 , the data could first be sent to through an intermediate relay system  103  before being sent to the final receiving computer system  101 . This intermediate relay system  103  is comprised of a chain of servers. The chain of servers could either be a single server or however many servers are required. When the intermediate relay system  103  is being used, each server along the chain will receive the data from the previous server or source computer system, and process the data. After the server receives the data, it will act as a de facto source computer system and repeat the communication process to the next server in the chain. Each server will perform this task the same way, until the data reaches a final server that will relay the data to the final receiving computer system  101 . After the data reaches the receiving computer system  101 , the same conversion to a readable clock will be performed to display the data to an end user  102 .
