Master Control...
This is where all the programs you see are controlled. It is the final control point before our transmitter. The operator has control over the many machines for playing back programs during the day. He or she is also responsible for recording programs which are transmitted via satellite, and for properly aiming and tuning the satellite equipment for news feeds. The operator on duty has a log (produced by the "traffic" department) which tells them which commercials to play at what times. WFMZ-TV was one of the first stations in the country to play back commercial material from optical laser disks.  This technology has been replaced by disk-array storage.  All of our commercials are stored on a large computer hard disk array.  That means that any commercial, promo, ID, or other material is instantly available to the operator.   The master control operator has monitors for the National Weather Service (in case of weather alerts) and for the Emergency Alert System.
