A LED matrix display having a variety of enhanced functionalities including: a scheduler which schedules tasks based upon commands correlated with real time; a tracking and accounting procedure which provides a database file which accounts for tasks as a function of the time a task is performed; sports display presentations of various sports information associated with different sports based upon corresponding sports IDs; the use of virtual display images or windows which may vary over time and which overlay template or faceplate images; and an improved error reporting capability in which detected errors are displayed using clear descriptive text information.

[ What is claimed is:] [1.] An electronic matrix display adapted to sequentially execute multiple display tasks, each display task for displaying corresponding image sequences (text and/or animation) for a predetermined duration at predetermined times, the matrix display comprising:means for determining real time;a schedule file containing a number of time commands each of which has a task initiation time entry and a task entry that relates to initiation of a display task dependent on time;means for automatically reading said schedule file;means responsive to each said time command of the schedule file and to the means for determining real time for executing each said display task sequentially so as to effect the display of the corresponding image sequences in a display task for said predetermined duration at said predetermined time, wherein said means for executing each said display tasks delays execution of the task entry of the given time command until the real time is greater than or equal to the task initiation time entry of the given time command or the prior display task has completed execution, whichever is later;said schedule file further comprises one or more synchronization commands;responsive to each given synchronization command, said means for executing display tasks resets to the first command and sequentially searches the commands in said file until a time command is found having a task initiation time that is equal to or greater than the real time, said means for executing display tasks delaying execution of the time command found until the real time equals the task initiation time of the time command found;means for detecting a change of the schedule file;means for generating an automatic synchronization command responsive to said means for detecting a change;responsive to said means for generating an automatic synchronization command, said means for executing display tasks resets to the first command and sequentially searches the commands in said file until a time command is found having a task initiation time that is equal to greater than the real time, said means for executing display tasks delaying execution of the time command found until the real time equals the task initiation time of the time command found;said means for detecting a change in the schedule file further comprises: means for checking for the existence of said schedule file, means for checking the static attributes of said schedule file, and means for checking the archive attributes of the schedule file.
