Abstract

Disclosed are a client-server system and its software for Olympic Results System. Each part in the system has redundancy, i.e., it consists of duplicated clients or database servers, and the databases are updated at the same time by the the software. This mechanism provides real-time and non-stop results services to users (scoreboards, TV graphic systems, TV Commentator Information Systems (CIS), etc., even if a part of the system stops by a trouble.

Redundant Results System for Nagano Olympic

      Disclosed are a client-server system and its software for
Olympic Results System.  Each part in the system has redundancy,
i.e., it consists of duplicated clients or database servers, and the
databases are updated at the same time by the the software.  This
mechanism provides real-time and non-stop results services to users
(scoreboards, TV graphic systems, TV Commentator Information Systems
(CIS), etc., even if a part of the system stops by a trouble.

      Timing Interface (TI) receives timer messages from a Timer
System.  It checks the message format validity and converts the
format of the messages to LAN format.  Event Controller (EC) is a
calculation engine of the Results System.  It calculates, for
example, time difference and ranking of each competitor using the raw
data from the Timer.  Then, EC stores the results to Database Server
(DB) and also sends a notification message, which informs the
database update to the requesters, i.e., TV Interface (TV),
Scoreboard Interface (SB) and  CIS Server (CI).  Event Management
(EM) updates the database by an operator's operation.  For example,
to input competitor's information,  start order of the competitors
and official's judge to the competition,  EM is used.  EM also sends
a notification message to requesters so that the requesters can know
the database is updated.  DB holds the information from EC and EM and
provides them to requesters by request messages (SQL request) from
the requesters.  TV provides an interface function to TV graphic
system.  By receiving the notification message from EC or EM, TV
sends a signal to the TV graphic system and lets it know the data is
available to read.  SB provides an interface function to  the
scoreboards in the venue.  Its function is almost same as TV.  CI is
a server of CIS.  When it receives a notification message, i t
requests information to DB according to the notification type.  Then
CI stores the information from DB in its storage and provides the
information to  CIS clients.

      Each part in the Results System is duplicated.  For example,
there are two  ECs in the system.  Timer messages are separated by a
separation box and go into the two TIs.  Each message has a unique
sequential number in it.  Each TI converts the messages to Results
LAN format and broadcast them to the LAN.  A TI message from TI-A is
identical to one from TI-B.  EC-A receives the TI messages from both
TI-A and TI-B.  The message from TI-A may arrive at EC-A earlier than
one...
