Broadcast Automation Software
Contents. History Originally, in the USA, many (if not most) authorities required a licensed to run every station at all times, meaning that every had to pass an exam to obtain a license to be on-air, if their duties also required them to ensure proper operation of the transmitter.
This was often the case on overnight and weekend when there was no present, and all of the time for small stations with only a contract engineer on call. In the U.S., it was also necessary to have an operator on duty at all times in case the (EBS) was used, as this had to be triggered manually. While there has not been a requirement to relay any other, any mandatory messages from the U.S. President would have had to first be with a sealed in a pink envelope sent annually to stations by the (FCC).
Gradually, the quality and reliability of electronic equipment improved, regulations were relaxed, and no operator had to be present (or even available) while a station was operating. In the U.S., this came about when the replaced the EBS, starting the movement toward automation to assist, and sometimes take the place of, the live (DJs) and. Early analog systems.
Harris automation system used at the former WWJQ (now ) in 1993. Early automation systems were systems which used. Later systems were 'computerized' only to the point of maintaining a schedule, and were limited to radio rather than TV.
Music would be stored on audio tape. On the tape marked the end of each song. The computer would simply rotate among the tape players until the computer's internal clock matched that of a scheduled event. When a scheduled event would be encountered, the computer would finish the currently-playing song and then execute the scheduled block of events. These events were usually, but could also include the station's top-of-hour, news, or a promoting the station or its other shows. At the end of the block, the rotation among tapes resumed. Advertisements, and the top-of-hour station identification required by law were often on 'carts'.
Short for cartridges, these were endless tapes similar to, were mechanically identical as well, and were called. The primary difference between carts and 4 track is two fold. The Cart had only two tracks and the 4-track (obviously) had four.
The Cart ran at 7 and 1/2 whereas the 4-Track ran at 3 and 3/4 IPS. Carts had a slot for a pinch roller on a spindle which was activated by solenoid upon pressing the start button on the cart machine.
The was spinning at full speed and this allowed for nearly instantaneous playback start without artifacts. Mechanical would rotate the carts in and out of multiple as dictated by the computer. Time announcements were provided by a pair of dedicated cart players, with the even minutes stored on one and the odd minutes on the other. This meant an announcement would always be ready to play, even if the minute was changing when the announcement was triggered. The system did require attention throughout the day to change reels as they ran out and reload carts.
It became obsolete when a method was developed to automatically rewind and re-cue the reel tapes when they ran out, extending 'walk-away' time indefinitely. Radio station may have been one of the world's first completely automated radio stations, built and designed by Brian Jeffrey Brown in 1963 when Brown was only 10 years old. The station broadcast in a classical format, called 'More Good Music (MGM)' and featured five-minute bottom-of-the-hour news feeds from the. The heart of the automation was an 8 x 24 telephone which controlled two reel-to-reel tape decks, one twelve inch machine providing the main program audio and a second seven inch machine providing 'fill' music. The tapes played by these machines were originally produced in the (MWF) Madison, Wisconsin production facility by WSJM Chief Engineer Richard E. McLemore (and later in-house at WSJM) with sub-audible tones used to signal the end of a song. The stepping relay was programmed by slide switches in the front of the two relay racks which housed the equipment.
The news feeds were triggered by a which was attached to a clock and tripped by the minute hand of the clock. And then reset the stepping relay. Originally, 30-minute station identification was accomplished by a switch in the control booth for sister station, whereupon the disc jockey in the booth would announce 'This is WSJM-AM and. (then pressing the momentary contact button).WSJM-FM, St. Joseph, Michigan.' This only lasted about six months, however, and a standard tape cartridge player was wired in to announce the station identification and triggered by the Western Union clock. Solidyne GMS200 tape recorder with computer self-adjustment.
Argentina 1980-1990 A different technology appeared in 1980 with the analog recorders made by Solidyne, which used a computer-controlled tape positioning system. Four GMS 204 units were controlled from a 6809, with the program stored in a plug-in. This system has a limited programming time of about eight hours. Satellite programming often used audible (DTMF) signals to trigger events at stations.
This allowed the automatic local insertion of ads and station IDs. Because there are 12 (or 16) tone pairs, and typically four tones were sent in rapid succession (less than one second), more events could be triggered than by sub-audible tones (usually 25 Hz and 35 Hz).
Modern digital systems Modern systems run on, where all of the music, jingles, advertisements, and other announcements are stored. These audio files may be either or uncompressed, or often with only minimal compression as a compromise between file size and quality. For, these disks are usually in computers, sometimes running their own custom, but more often running as an on a stable OS like /, or others. Simian by Broadcast Software International, TuneTracker, ENCO, and Radio DJ are examples of Modern multifunction Broadcast Automation Software systems. There are many other software packages available. Was an important advance of these systems, allowing for exact timing.
Some systems use satellite to obtain exact, for perfect with satellite-delivered. Reasonably-accurate timekeeping can also be obtained with the use of (IP) like (NTP). Automation systems are also more interactive than ever before with (DAW) with and can even record from a to play back an edited conversation with a telephone caller. This is part of a system's live-assist mode. The use of automation software and to replace live DJs is a current trend in radio broadcasting, done by many and stations. Stations can even be voice-tracked from another city far away, now often delivering sound files over the Internet.
In the U.S., this is a common practice under controversy for making radio more generic and artificial. Having local content is also touted as a way for traditional stations to compete with, where there may be no on the air at all. Solidyne 922: The first bit compression card for PC, 1990 A commercially available, for-sale product named was introduced by Oscar Bonello in 1989. It is based on, the same principle being used in most modern lossy audio encoders such as and (AAC), and it allowed both broadcast automation and recording to. Television In television, is also becoming more practical as the storage space of increases. And, as well as (DOG or BUG), can all be stored on remotely controlled by computers utilizing the and the (VDCP).

These systems can be very extensive, tied-in with parts that allow the 'ingest' (as it is called in the industry) of video from satellite networks and (ENG) operations and management of the video library, including archival of for later use. In, (PMCP) is then used to pass information about the video through the airchain to (PSIP), which transmits the current (EPG) information over digital television to the viewer.
