Definitions

  • This invention relates to a Fully Automated Radio and TV Programme Selection System. (Fully Automated Radio Disc Jockey System).
  • a radio disc jockey selects and lines up a record then prepares for his next speech input .
  • the music comes to the fade out he switches the microphone on and makes his announcement .
  • the music comes from one source, eg. record, tape, compact disc , in a running sequence of several songs.
  • the other programme inputs such as disc jockey announcements, commercial intervals, news
  • the entertainment programme input (music) is seperated from the information input (speech) .
  • a speech tape switches on , meaning another programme source (speech / information) follows or is mixed over the outro of the music (eg. an announcer speaks over the outro of a song).
  • the music/ entertainment source switches on .meaning it follows or is mixed under the outro (fade out) of the speech / information (eg. the annoucer finishes his last sentence over the intro of the next song) .
  • the Fully Automated Radio and TV Programming System consists of five main parts which are interconnected:
  • the Audio Matrix audio mixer with preamplifier
  • EMS Emergency Music Start Function
  • the Music Control Board (abbreviated MCB)
  • the Speech Control Board (abbreviated SCB)
  • the Music Play Back Counter (abbreviated MPC)
  • the MPC is an optional feature of the Fully Automated Radio and TV Programming
  • the Audio Matrix is an automatic audio mixer with preamplifiers .
  • the music/ entertainment signal coming from its source will be fed through a control at the Music Control Board and then diverted to the stereo music / entertainment input at the Audio Matrix
  • the Audio Matrix has two seperate inputs for track one and track two (right channel and left channel) for each tape machine connected to the speech / information input .
  • the right speech channel carries five kilo hertz pilot tones to indicate several functions to the Speech Control Board . These will be described at a later stage .
  • the output of the right speech matrix will be supplied to the pilot tone decoder at the Speech Control Board.
  • the left speech channel which carries the actual information input as a mono signal will be split and distributed to two matricies (stereo).
  • One of the outputs of these matricies is sent to the left channel mixer the other to the right channel mixer (both in the same diagram) .
  • the purpose of these mixers is to mix the music / entertainment inputs with the speech / information inputs .
  • the mixer has a third input,named Volume Control This input is controlled by the Speech Control Board . If the Volume Control input is low the speech / information input will be closed, and the music / entertainment input will be fully opened . If the Volume Control input is high, the speech / information input will be fully opened and the music / entertainment input will be reduced in volume .
  • the level of reduction is variable and can be preset with a potentiometer .
  • the Emergency Music Start Function is shown in the Music Control Board diagram.
  • the Emergency Music Start Function is a pure back up control to reset the whole Fully Automated Radio and TV Programming System,should a fault occur. Monitoring the left TX output , the Emergency Music Start Function will trigger off if it notices dead (meaning no signal at all) for more than 17 seconds.
  • Dead air might appear e.g. if a tape drive was not loaded,pilot tones were forgotten to be recorded, tapes develop a mechanical fault or through a fault in the Fully Automated Radio and TV Programming System itself, to mention just a few.
  • the main purpose of the Emergency Music Start Function is to restart the music / entertainment source; therefore the Emergency Music Start Function will give a start signal to the Music Start input of the Music Control Board .
  • the Emergency Music Start Function can be switched off with switch S15 (e.g. for test purposes) .
  • the Emergency Music Start Function works basically on the same principles as the Volume Level Indicators which will be discribed later.
  • the incomming signal is regulated by a potentiometer (pre set),then put through a rectifying amplifier , a conventional OP (e.g. LM 741) with the non inverting input connected to ground (minus pole).
  • This signal will be sent to the prime input of a 1:2 transformer .
  • the transformer output will be rectified with a diode .
  • This signal will be directly distributed to the non inverting input of another OP , the other transformer output is connected with the inverting OP input .
  • Parallel to the OP inputs is a capacitor and the signal can be regulated by a variable resistor parallel to the capacitor .
  • the non inverting input of the OP is also connected with a resistor to KP (plus pole) and a capacitor to ground, (minus pole) .
  • the offset / control voltage input of this OP (Pin 1) will also be connected to ground.
  • the OP output will be delivered to two transistors which convert this positive signal to a negative potential at the RC-combination of the following timer, providing the Emergency Music Start Function input has a sufficiently loud signal . Should the signal strength fall below the preset level, the RC-combination at the timer will start to load up. If the signal strength fails to improve within the RC-combination's charge up time, which is less than one second, the timer output will fall from a positive to a negative potential .
  • the outputs are feeding conventional inverters which distribute the relevant signals .
  • the two timers are set / started by the Music Start impulse coming from the Speech Control Board .
  • the timer is a Integrated Circuit which is self resetting .
  • a further timer follows because the time between the impulse and the reset is too short to trigger a relay .
  • the second timer's only purpose is to give a sufficiently long trigger impuise.inverted to the first timer's output.
  • the output of the second timer goes to switch S15 and from there to the Music Play Back Counter , to the Speech Control Board , through a diode to the Music Start input of the Music Control Board and to relay E23; this is for external connection .
  • Relay E23 might load compact disc players or tape machines which need a preprogrammed running order (like the Sony MTL 10 Cassette Player) .
  • a Five Cassette Loader which triggers five or two (depending on its switch setting) different switches at the relevant machine , one after another with a pause in between, if it receives one Emergency Music Start trigger.
  • Relay E23 might also trigger alarm systemms to alert radio station staff of the occurance of faults during the programme.
  • the main purpose of the Music Control Board is to monitor the music / entertainment source. There are three diffre ⁇ t possibilities (modes) to monitor the song .
  • an external controller eg. a computer with a programmed database of the song order and duration in connection with a timer
  • pilot tone operation mode one would require a three track source for stereo operation because one track is needed for the pilot tones.
  • the monitor will signal twice
  • the timing for the actual command to indicate the 50 % Volume Stage is variable and might be during or after the outro of a song . It relates to the sensitivity setting of the 50 % Volume Level Indicator , the pilot tones or the external commands.
  • the 50 % Volume Stage gives a Start Speech Signal to the Speech Control Boardjneaning it starts a speech / information tape, as well as giving a set / count signal to the Music Play Back Counter .
  • switch S8 is set accordingly and switches S9 and S10 are in pilot tone operation mode (two track recorded source)
  • the source may not be stopped if its start / stop function is controlled by relay E22.
  • the PHot Tone Controlled Cassette Change Function with I 16 might override the switch off command .
  • This Function is designed for sources with long switch over times , eg from cassette one to cassette two or side A to side B (a typical machine of this kind would be the Sony 10 Cassette Changer MTL 10 ) .
  • the pilot tone decoder If it receives a 5 khz pilot tone before the timer facility with 1 14 stops the source this function will override the timer .
  • Relay E22 will then stop the source as soon as the Pilot Tone Controlled Cassette Change Function receives a second 5 khz tone from the right channel of the source unless a Start Music signal was received before from the Speech Control Board .
  • the Pilot Tone Controlled Cassette Change Function with 1 16 does not work in the pilot tone operation mode, set by switch S9 and S10.
  • the pilot tones on tapes for sources with long switch over times can be recorded accordingly by ommitting the pilot tone for the 100 % Volume stage at the end of the last song on the relevant side / tape . Instead it will be recorded at the beginning of the next side / tape exactly four seconds before the first song starts : (For sources with fast switch over times, such as the operation with the Music Play Back Counter, this pilot tone will be recorded at the end of the last song.)
  • the pilot tone decoder is protected by a delay which prevents it from receiving more than one impulse within approx. three seconds.
  • a further input of the Music Control Board is the Music Start connection which receives its signal from the Speech Control Board .
  • This 80 seconds timer primarily protects the 50 % Volume Level Indicator from giving false signals during a song's intro . It can be switched off for test purposes or during pilot tone controlled mode with switch S13.)
  • this timer will reset the counters 1 14 / 1 16 / 1 18 and keep them in that position for 80 seconds.
  • the Music Start signal will also trigger relay E22 provided the Security Music Start function with LDR 1 indicates that the music / entertainment source is in stop position .
  • the Security Music Start function is a safe guard to prevent relay E22 making a Start ingger while the connected drive is in operation,because such an additional Start signal would in fact be regarded as a Stop signal by the relevant play back source .
  • the Security Music Start function requires an opto isolator with its LED connected to the motor (or any other play back on indicator) at the source, which is controlled by relay E22
  • Switch S11 cuts the pilot tone decoder off and connects it with a test input .
  • a high signal during Volume Level Indicator Control mode through Switch S12 overrides the 50 % level indicator and prevents it from giving the start speed signal This function is useful when the music / entertainment source carries a prepackaged programme which does not require further speech / information inputs.
  • switch S12 requires an opto isolator with its LED connected to a play back on indicator at the source, which plays the prepackaged programme, it should be connected in a way that the LED switches and stays off as soon as the prepackaged programme ends . This will let the Fully Automated Radio and TV Programming System resume automated programming .
  • the music / entertainment input can be played from various sources, provided these sources have electro-mechanicaly switched drives.
  • the music / entertainment input is not limited to tape machines but can be connected to any signal source such as Compact Disc Players, Record Players, Radio Receivers to mention just a few.
  • Music / entertainment sources can either be controlled by relay E22 on the Music Control Board , or by the Start / Stop Control as shown in the Other Start / Step Functions Diagram, or by the Music Play Back Counter .
  • Relay E22 gives both, the start and the stop commands. This can be used for one button only controlled Play Back sources . This option requires the use of the Security /Music Start function to prevent Start commands to stop the drive.
  • the Qther Start / Stop Functions set up will be connected to the Music Control Board outputs which were designed to feed the Music Play Back Counter .
  • the Other Start /Stop Functions sel up has two relays to send a seperate Start and Stop impulse to the music / entertainment source.
  • the Music Play Back Counter was invented to increase the reliability of the Fully Automated Radio and TV Programming System,to simplify the music / entertainment recording process and to increase the capacity of the whole Fully Automated Radio and TV Programming System .
  • the Music Play Back Counter can be used with any amount o f single or reverse direction drives, as long as their quantity is higher than two.
  • the music / entertainment tape machines used in conjunction with the Music Play Back Counter can be either Reel To Reel or Cassette drives. In either case the should be equipped with electro-mechanicaty operated Start , Stop and Rewind functions (so called soft touch button operation). The function switches of thos e drives have to be replaced by the contacts of the relevant relay in the Music Play Back Counter.Reverse machines should have seperate Start buttons for each direction.
  • the Idea of the Music Play Back Counter is to play a certain amount of songs on each side of a tape .
  • the counter as shown in the diagram is set to play eight song s (on industrial recorded tapes), 15 songs (on C90 cassettes) or 19 songs (on C120 cassettes).
  • the setting can be programmed for three different steps (with switches S16 and S17 ) between two and 99 songs ; or even from 2 - ⁇ songs if the th e capacity or the combination of counter IC 1 and counter IC2 will be expanded.
  • the following discription will always relate to a setting of 19 songs, which is nevertheles s the most economical and realistic setting for cassette drives .
  • the programme sequence resembles the following example: Song 1 - speech / information , song 2 - speech / information, song 3 - speech / information ......... song 19 - speech / information ; song 1 side two (flip side)- speech / information , song 2 side two - speech / information song 19 side two speech / information ; song 1 cassette two side 1 - speech / information . «and so on .
  • While recording music tapes there are two items to watch: to count the exact amount of songs and to watch that the songs on the flip side are marginally shorter than on the first side (tape length Side 2 ⁇ Side 1 ).
  • the set /song-count impulse is given by the 50 % Volume Stage as indicated by the Music Control Board . This makes sure that the Music Play Back Counter counts even if the tape drive does not stop .e.g. if the announcement is shorter than the fade out plus the four seconds stop break.
  • the Music Play Back Counter actually counts the music / entertainment inputs rather than the songs as such. This means if two songs are faded into another, there is no speech / information input between the two songs, the counter will assume that only one song was played.
  • the Music Control Board is in Volume Level fixticator Mode it is possible to play almost all commercially recorded tapes on the music / entertainment cassette recorders which are controlled by the Music Play Back Counter .
  • Commercially recorded tapes do not restart side 2 exactly after the end of the last song on side 1 Therefore they can only be played on one side.
  • the switches S20 - S23 will enable the four drives individualy to be switched into Single Sidernode. As soon as the last song on side 1 in this drive finishes the Single Side mote will rewind the tape to the beginning of side one and another drive will be started with the next Start Music Play Back Counter signal.
  • the Count Number cannot be set individually for each drive. Therefore the lowest song count of all two or four tapes should be selected. The counter will skip songs which follow after the highest setting . Accordingly it will restart the reverse side after the set song.
  • the counter setting is 15 but there are 19 songs on the tape the Music Play Back Counter will skip the songs 16 - 19 . So side 2 of that tape will be started after song 15 on the first side. If this tape was recorded for a counter 19 setting side 2 will now probably start in the middle of its third or fourth song. It is then also advisable to switch off this drive's reverse function .
  • the Music Play Back Counter receives an Emergency Music Start signal it will firstly check if a music / entertainment drive is in operation . If not ,the reason for a blank TX signal must be suspected to come from a speech / information drive . This will then be rewound , as discribed before, and the Music Play Back Counter will start the next lined up song without taking further action .
  • the Music Play Back Counter receives an Emergency Music Start signal and a music / entertainment drive is in operation it will start the next music / entertainment machine and rewind side 1 of the tape which caused the fault .
  • the speech / information tape machines used in conjunction with the Speech Control Board can be either Reel To Reel or Cassette drives . In either case the should be equipped with electro-mechanicaty operated Start , Stop and Rewind functions (so called soft touch button operation ). The function switches of those drives have to be replaced by the contacts of the relevant relay in the Fully Automated Radio and TV Programming System.
  • the running order of the speech / information tape machines is set by Counter IC4 .
  • the counter outputs Q o - Q 9 are connected to a 15 Pin distributor socket . Further connections are the socket outputs 1 & 2 & 3 & 4 for the tape drives and the Reset (RST) Pin which is wired up to the reset input of counter IC4.
  • the plu g inserted into this socket will operate as a programme disc . Every counter output will be assigned to a tape drive to programme the running order .
  • the operational stages of the Speech Control Board are basically indicated by gcounter
  • the delay inputs are a pilot tone indicator (different to the one on the Music Control Board ), which monitors the right channel of all speech / information tapes, and the Start Speech input which receives its signal from the Music Control Board. This signal is transformed to a single, short needle impulse so that it does not overshadow the information comming from the pilot tone indicator .
  • Counter 1 10 sets four steps:
  • the speech / information sources are off , the TX signal is broadcast entirely from the music / entertainment source, the Volume Control input at the Audio Matrix is low , the pilot tone indicator's input is closed , the 17 seconds timer with 1 12 is held in reset position and Flip /Flop I 14a is enabled to trigger Flip /Flop I 14b , if required,to put Drive 4 prior to the other speech / information drives.
  • the Volume Control input at the Audio Matrix becomes high , a speech / information drive will be started , the pilot tone indicator's input is now open , the 17 seconds counter is still held in reset position.
  • the next impulse to set 1 10 will be a pilot tone on the currently playing speech / information tape . This tone indicates that the speech/ information input will end soon. This impulse sets the counter 1 10 to :
  • the Volume Control input at the Audio Matrix stays high but the music / entertainment source is restarted (with a signal sent to the Music Control Board ), the speech / information drive continues to play , the 17 seconds counter is now started.
  • 10 can be a pilot tone on the currently playing speech / information tape . This tone indicates that the speech / information input will now end .
  • the Plug / Programme Disc outputs 1 & 2 & 3 ( Drive 1 - Drive 3 ) and the output of switch S2a ( Drive 4 ) determine the tape drive which will be put on the air.
  • 10 output Q1 or Q2 ( Point Z ) put the currently chosen speech / information drive in play back mode .
  • a further signal (Point A) comes from I 1 0 output Q3 .
  • a high signal at point Z will put the chosen drive in play track mode . If Point Z turns low and Point A stays low the drive will rewind the tape . If a high Point Z becomes low but Point A switches to high the drive will be stopped .
  • the following controls (shown to the left in the block diagram) will give commands to the tape machines .
  • the relevant trigger will be Start or Stop or Stop and Rewind
  • Those controls consist of four Flip / Flops, four Inverters, eight And- Gates, two Delays and two Needle Impulse Senders. This description relates directly to the Speech Control Board operation with soft touch button controlled tape drives and the controls shown in the main Speech Control Board Diagram .
  • the controls for the Speciai Cassette Drives are similar.
  • the diagram for the Speech Control Board shows the controls to run four different speech / information tape machines . This should be sufficient capacity to run even radio stations with a high speech / information output. Nevertheless further tape drives may be connected by expanding counter IC4 and additional control set ups following points A and Z marked in the diagrams.
  • the diagram Special cassette Drive Connection shows a tape set up with three drives which was specially designed for this Fully Automated Radio and TV Programming System . It can be used instead of soft touch operated,commercially available machines. This is a low cost alternative, with the additional advantage that the mechanical response delay is shorter than with usual soft touch operated tape decks .
  • the mechanical drives have an electro magnet . If this magnet is in operation the drive will be in Play Back mode.otherwise it will be in Rewind mode . The Stop mode is the rewind mode with the motor switched off.
  • Tape Deck One has a further play back amplifier for a third track to play stereo speech / information inputs, if required. Stereo inputs have to be recorded on three track machines. Otherwise Tape Deck One needs to be switched to Mono play back mode .
  • the Speech Control Board Special Cassette Drive Connection Block Diagram shows the cassette end indicators (filp / flops) , auto mute facilities (to switch play back amplfiers off when not in use) and it also shows the relevant controls following the points A and Z in the main Speech Control Board Diagram. Therefore the additional controls shown in the main diagram will not be used .
  • a special Plug / Programme Disc is shown in the Remote Fecoroing Control Disc Diagram . This is a special connector to enable remotely controlled recordings with the same tape machine which is connected to the Fully Automated Radio and TV Programming System . Obviously , this is only possible with tape machines which are fitted with a recording facility .
  • the Remote Recording Control Disc will indicate when the machine is available for recording and if the recording is in progress it will divert eventual playback commands to other drives .
  • Switch S6 can delay the high command to the Audio Matrix.Such a delay would take into consideration that there is a short time difference between the Start Speech signal and the actual start of the tape due to mechanical inertia .
  • Tapes can be changed while transmission is in progress. This should be done while the relevant speech / information drive is in stop position . New tapes should be rewound to the beginning of a speech/ information input .
  • the speech / information Drive 4 has some special functions .
  • Switch S2 determines if Drive 4 will be played in a programmed order designated by the Programme Disc/ Plug and Counter IC4 or if it may override the counter ( order or timer mode ).
  • switch S2 is set to Toner Play / Override, a high impulse at the input of Flip / Flop
  • This impulse can be a remotely sent signal (for example from an outside broadcast van) or a timer . This choice will be selected with switch S7 .
  • the timer if selected.sets the Flip / Flop shortly before the full hour to broadcast e.g. the news or any other required speech / information item almost precisely on the hour, namely when the current music / entertainment input ends.
  • a time signal (e.g. the Greenwich Bleeps or a station call sign) can be triggered off at the precise time when Flip / Flop
  • Switch S4 sets the timer .
  • switch S1 is set in Special position Drive 4 will rewind automatically after its programme input irrespectively of stop signals given by pilot tones. (This might shorten the 17 seconds talk over which is usually required for rewind commands).
  • the Drive 4 function as the source input for a live-studio .
  • the Drive 4 Start Relay will trigger an On Air Light to notify the live Disc Jockey.
  • the Base Time Diagram shows a 1 Hz supply for all digital timers in the Fully Automated Radio and TV Programming System and a 100 Hz supply to test the 3600 seconds timer, which is connected to Flip / Rop I 14a on the Speech Control Board. To test this timer, switch S3 has to be set in test position . The timebase will be taken from the alternation of the AC-mains supply . For operation with no AC supply (e.g. of batteries in remote areas) the Basis Time has to be created by a oscillator, preferably a quartz oscillator.
  • the Fully Automated Radio and TV Programming System can also be used to run a Fully Automated Television Station .
  • a Fully Automated Television Station works similarly to a Fully Automated Radio Disc Jockey System and mixes different programme inputs which were originally separated on different video tapes in different video recorders .
  • the Fully Automated Television Station will mix the programme inputs according to the outlined example :
  • a link tape eg.commerciais,weatherforcast or a music video
  • another programme source speech / information
  • the entertainment source switches on, meaning it follows or is mixed under the outro of the information.
  • the Fully Automated Television Station's Music Control Board must not be set to Volume Level indicator Mode.
  • Other inputs than music e.g. Films TV, Shows,News
  • the Fully Automated Television Station should only be run on pilot tone (or external) commands . Following this recommendation there is one of the audio tracks to be used as the pilot tone channel, the other tracks are then free to carry the audio signals .
  • the audio outputs of the video recorders will be connected to the Fully Automated Radio and TV Programming System, in the same way as signal sources / tape drives are connected for Fully Automated Radio Stations.
  • the Video Outputs will be mixed in a separate video mixer, which might be controlled by connection to the Music Volume Contol output at the Speech Control Board or by any other possible means. This might also include additional contacts at the relays on the Speec Control Board which give Start and Stop signals to the drives .
  • a selection of suitable Video Mixers is already commercially available .
  • the Studio Controls are a little set up to support the recording of programme inputs which will be played on the Fully Automated Radio and TV Programming System .
  • the Studio Controls consist of Volume monitors and pilot tone generators .
  • This Recording Monitor has two Volume Level Indicators like the ones on the Music Control Board . One 50% Volume Level Indicator and one for the 100% level. They will be connected to the headphone output of the music recording machine in the studio . At their output are two lamps and a buzzer which can be switched off .
  • the Volume Level Indicators At the start of the recording of a song the Volume Level Indicators will be set.
  • the 50 % lamp should switch off (and the buzzer should start during the outro) indicating the moment when the speech / information input would start if played by the Fully Automated Radio and TV Programming System .
  • the 100% lamp switches off at the actual end of the song . If the lamps switch off at the required moment the recording will be suitable to be played on the Fully Automated Radio and TV Programming System switched to Volume Level Indicator mode .
  • the Recording Monitor has to be set manually .
  • Start , Stop and Record functions optional automatic facilites have been invented .
  • An additional Setl Start swtich will start the recorder and the Recording Monitor simultaneously and also take the 80 seconds timer at the Music Control Board into consideration .
  • Three seconds after the end of the song the Recording Monitor will stop the recorder automatically, provided the song is suitable . It is recommended that the music recorder should be preceided by an electronic limiter / compressor to increase the Volume Level Indicator's reliability .
  • the Studio Controls also have a 5 khz oscillator to record pilot tones.
  • the pilot tone time will always be of the same duration, suitable for the decoders irrespective the length of time the signal switch was pressed .
  • the pilot tone timer for the automatic facility needs different RC (resistor / capacitor) combinations for manual operated recording drives than for soft touch operated ones . This is due to longer mechanical inertia of electro-mechanically operated drives .
  • Opto isolators can be connected to the set switches (the set/ start swit ch and the switch for the start music command ) to attach a stop clock.

Lorsque la source de plage musicale commence à s'estomper, une bande d'informations se met en route et est fondue à la plage musicale. A la fin réelle de la plage musicale, sa source sera stoppée. Lorsque la plage d'informations est sur le point de se terminer, la source de plage musicale se met en route et est fondue aux informations. A la fin réelle de la plage d'informations, l'entraînement de la bande sera stoppé. Lorsque la plage musicale s'arrête à nouveau, le processus décrit ci-dessus se répète. Les instructions de plages d'informations diverses peuvent être programmées. La source de plage musicale peut être n'importe quelle source de signaux. Des modules spéciaux (tels qu'un compteur de reproduction musicale) peuvent être appliqués. La source de plage musicale peut être contrôlée par des indicateurs de niveau de volume, des tonalités pilotes ou des commandes externes. Tout le système est protégé contre des erreurs de manipulation.
