Abstract

A method and apparatus for enabling subsequent verification of the broadcasting of one or more commercials by a radio station during a commercial break comprises recording the commercials broadcast during the commercial break on a recording means such as a cassette tape recorder 10. The signal which is recorded by the tape recorder 10 is derived from that being broadcast by a transmitter 3 of the radio station. A control circuit 12 is responsive to the beginning of each commercial break, such as by a cart rack 8 commencing to play the first commercial such that the tape recorder 10 is activated and is maintained activated until a predetermined time has elapsed after the last of the commercials of a commercial break has been broadcast. As described a dialler 16 dials a speaking clock of a telephone network 15 for recording the time simultaneously with the commercial.

Description

"A method and apparatus for verifying the broadcasting of a commercial" The present invention relates to a method and apparatus for enabling subsequent verification of the broadcasting of one or more commercials on a radio station.
Commercials which are broadcast during commercial breaks on radio stations, and in particular, on commercial radio stations are a particularly important source of income for the radio station. In many instances, those who contract with a radio station to broadcast a commercial seek verification that the commercial has been broadcast and the time at which the commercial was broadcast. It is therefore essential that a radio station can verify that each commercial was broadcast, and furthermore, was broadcast at the agreed time.
It is known, and indeed, it is a requirement in most countries that each radio station records its entire output each day. This is achieved, generally, by using one or more recording devices which are generally referred to as slow speed loggers. The slow speed logger or loggers receive the signal of the radio broadcast from the transmitter. A radio receiver receives the signal from the transmitter, and relays the signal to the slow speed logger or loggers.
However, the verification of the broadcasting of a commercial and the time at which the commercial was broadcast using a slow speed logger suffers from three serious disadvantages. Firstly, it is necessary to play through a significant proportion of the recorded material on the slow speed logger, and since each logger records onto an eight hour tape, in certain cases, one would have to listen through virtually the entire eight hours of playing in order to verify the broadcasting of a commercial. Secondly, it is impossible to determine from the play back from a tape recorded from a slow speed logger the time at which the commercial was broadcast with any degree of accuracy.
Thirdly, the quality of the recording made by a slow speed logger is relatively poor, and could tend to give the impression that the sound quality of the commercial was poor.
Additionally, as well as the above disadvantages, in order to play back a tape recorded on a slow speed logger, a further slow speed logger is required which involves considerable expenditure and training of at least one person to operate the logger in playback mode.
There is therefore a need for a method and apparatus for enabling subsequent verification of the broadcasting of one or more commercials on a radio station which overcomes these problems.
The present invention is directed towards providing such a method and apparatus.
According to the invention there is provided a method for enabling subsequent verification of the broadcasting of one or more commercials by a radio station during a commercial break, the method comprising the steps of activating a recording means at the beginning of each commercial break for recording the commercials, delivering the signal which is being broadcast by a transmitter of the radio station to the recording means for recording thereof at least during most of the time during which the recording means is active, maintaining the recording means active for recording until a predetermined time has elapsed after the last of the commercials of a commercial break has been broadcast, and deactivating the recording means after the predetermined time has elapsed.
In one aspect of the invention the recording means is activated in response to activation of a cart rack for playing the first of the commercials during a commercial break.
In another aspect of the invention a radio receiver receives the signal from the transmitter, and the received signal is relayed from the radio receiver to the recording means.
Preferably, the method further comprises the step of simultaneously recording the current time by the recording means as the commercial is being recorded.
Advantageously, the current time is recorded by feeding a signal from a speaking clock of a telecommunications network to the recording means. Ideally, the method further comprises the step of dialling the speaking clock of the telecommunications network as the recording means is being activated.
Preferably, the commercial breaks of a radio station are recorded sequentially.
In one aspect of the invention the broadcasting of one or more commercials is verified by replaying the signals of the commercials recorded on the recording means.
Preferably, the commercials are recorded by a recording means provided by a cassette tape recorder.
Advantageously, the commercials are recorded on a magnetic tape.
Ideally, the predetermined time is sufficient for recording the beginning of the programme which follows after each commercial break. Preferably, the predetermined period of time is at least three seconds.
Advantageously, the predetermined period of time is at least five seconds. In general, the predetermined period of time is approximately ten seconds.
Additionally, the invention provides apparatus for enabling subsequent verification of the broadcasting of one or more commercials by a radio station during a commercial break, the apparatus comprising a recording means for recording the commercials being broadcast, a delivering means for delivering the signal being broadcast by a transmitter of the radio station to the recording means, a timing means for timing a predetermined time period after the last of the commercials of the commercial break has been broadcast, and a control means for controlling the operation of the recording means, the control means being responsive to activation of the cart rack for activating the recording means on commencement of the commercial break for recording the signal being delivered to the recording means, and being responsive to the timing means having timed the predetermined time period for deactivating the recording means.
In one aspect of the invention a connecting means connects the control means to an output of the cart rack so that the control means activates the recording means in response to activation of the cart rack.
Preferably, a communicating means is provided for communicating the recording means with a clock means for recording current time on the recording means simultaneously with recording of the commercials, the communication means being controlled by the control means. Advantageously, the communicating means comprises a telephone link, and an initiating means for dialling a speaking clock of a telephone network.
Ideally, the predetermined time period is sufficient for recording the beginning of the programme which follows after each commercial break. Preferably, the predetermined time period is at least three seconds.
Advantageously, the predetermined time period is at least five seconds, and preferably, the predetermined time period is approximately ten seconds.
It is preferable that the recording means is a tape recorder, and ideally, a cassette tape recorder.
Further the invention provides use of the method according to the invention and the apparatus according to the invention in the broadcasting of commercials from a radio station for facilitating subsequent verification of the broadcasting thereof.
The invention will be more clearly understood from the following description of a preferred embodiment thereof which is given by way of example only, with reference to the accompanying drawings, in which: Fig. 1 is a block representation of conventional broadcasting apparatus of a radio station, Fig. 2 is a block representation of apparatus according to the invention connected into the broadcasting apparatus of the radio station of Fig. 1, and Fig. 3 is a block representation of part of the apparatus of Fig. 2.
Referring to the drawings, and initially to Fig. 1 there is illustrated in block representation broadcasting apparatus which is indicated generally by the reference numeral 1 of the type which is normally used by a radio station for broadcasting. The apparatus 1 comprises an on-air mixer 2 into which all signals to be broadcast are feed on a number of different lines (not shown). The signals to be broadcast are mixed in the on-air mixer, and are relayed to a transmitter 3 from which they are broadcast. A radio receiver, namely, a tuner 4 receives the transmitted signal from the transmitter 3, and the received signal is relayed to three slow speed loggers 5 which automatically record the entire broadcast output of the radio station. A cart rack 8 houses a stack of cart machines from which commercials are stored and played.The output from the cart rack 8 is delivered to the on-air mixer 2. The cart rack 8 is activated to play each stored commercial individually by operation of a remote button switch (not shown) which delivers a signal to the cart rack 8 to play the respective commercials. The respective commercials are broadcast in the stored sequence each time the button switch is activated. Typically, the button switch is activated by the disc jockey or programme presenter when the commercials are to be broadcast. The operation of such apparatus 1 including the on-air mixer 2, transmitter 3, tuner 4, slow speed logger 5 and cart rack 8 will be well known to those skilled in the art, and it is not intended to describe it in further detail.
Referring now to Figs. 2 and 3 apparatus according to the invention indicated generally by the reference numeral 9 for enabling subsequent verification of the broadcasting of one or more commercials during a commercial break by the radio station on the apparatus 1 will now be described. The apparatus 9 comprises a recording means, namely, a standard cassette tape recorder 10 for recording the commercials. A delivering means which is provided by the tuner 4 which receives the signal from the transmitter 3 for relaying to the slow speed logger 5, also relays the signal from the transmitter 3 to a first input of the tape recorder 10. The tape recorder 10 is operated under the control of a control circuit 12, illustrated in Fig. 3 for recording the commercials as they are being broadcast during a commercial break.A second input of the tape recorder 10 is connected by a communicating means, namely a dedicated telephone line 14 to a public telephone network 15. An automatic dialler 16 is provided in the telephone line 14 for dialling a speaking clock in the telephone network 15. The control circuit 12 as will be described below activates the dialler 16 at the beginning of a commercial break to dial the speaking clock so that the time can be simultaneously recorded from the speaking clock onto the tape of the tape recorder 10 as the commercials are being recorded. In this way, not only can verification that the commercial or commercials were broadcast be obtained, but the precise time at which the commercials were broadcast can also be verified.
Referring to Fig. 3 the control circuit 12 comprises a four input first OR gate 19, each of the input pins, namely, pins 1 to 4 are connected to output pins 1 to 4 of the respective cart machines in the cart rack 8 through respective identical circuits comprising a resistor Rl and a diode D1 for stepping down the output voltage from the cart machines of the cart rack 8 from approximately 14 volts to 5 volts. Only one of the circuits comprising the resistor R1 and the diode D1 is illustrated. The output pins 1 to 4 of the cart rack 8 deliver approximately 14 volts as each cart machine in the cart rack 8 is playing a commercial.On any one of the input pins 1 to 4 of the OR gate 19 going high, a high is applied to the output of the OR gate 19 which is applied to two of the input pins 1 and 2 of a second OR gate 20. A high on any of the input pins 1 to 4 of the second OR gate 20 causes the output of the second OR gate 20 to go high, the high on the output of the second OR gate 20 is applied through a resistor R6 to the base of a power transistor TR1 which switches on the transistor TR1. The transistor TR1 in turn activates a relay RLl which closes the contact of the relay RL1 for activating the tape recorder 10 and maintaining the tape recorder 10 in the recording mode.
A jack plug 22 fed through the contacts of the relay RL1 is connected to the remote on/off switch of the tape recorder 10 for controlling the tape recorder 10 in response to the relay RL1. The output of the second OR gate 20 is also connected to the dialler 16, and on the output of the second OR gate 20 going high the dialler 16 is activated for dialling the speaking clock.
A third OR gate 23 in combination with a timing means, namely, an RC timing circuit comprising a resistor R5 and a capacitor C1 times a delay period and holds the pins 3 and 4 which are joined together of the second OR gate 20 high for a predetermined time period after the last of the commercials has been broadcast. The predetermined time period is determined by the time constant of the RC circuit, which in this case is approximately 10 seconds. Accordingly, the tape recorder 10 is maintained active for recording the beginning of the programme after a commercial break so that the end of each commercial break can readily be determined on listening to the tape recorded by the tape recorder 10. The third OR gate 23 comprises four input pins, namely, pins 1 to 4 which are joined together and are fed from the output of the first OR gate 19. A high on any of the pins 1 to 4 on the third OR gate 23 causes the output of the third OR gate 23 to go high, and the high signal on the output of the third OR gate 23 is maintained after the output of the first OR gate 19 has gone low by the RC timing circuit for the predetermined time period of ten seconds.
In use, the tape recorder 10 is maintained at all times in the recording mode. On the remote button switch (not shown) being activated at the beginning of a commercial break, the first commercial in the cart machines of the cart rack 8 is broadcast. On operation of the remote button switch, the output on pin 1 of the first cart machine applies a high to the first input pin 1 of the first OR gate 19, thereby putting the output of the second OR gate 20 high, and switching on the transistor T1, and in turn the relay RL1 for activating the tape recorder 10 which immediately commences recording the first commercial of the commercial break. Also on the output of the second OR gate 20 going high, the dialler 16 is activated to dial the speaking clock of the public telephone network 15.
For so long as the first cart machine is playing the commercial, the output on the first OR gate 19 remains high thereby maintaining the transistor TR1 in the on state, and accordingly, the tape recorder 10 continues to record. On the next cart machine being activated, the output pin 2 of the second cart machine applies a high to the second pin, namely, pin 2 of the first OR gate 19 thereby a high continues to be maintained on the output of the first OR gate 19 which in turn maintains the transistor TR1 switched on, and in turn the tape recorder 10 continues to record.
As the cart machines of the cart rack 8 sequentially are activated for playing the commercials, the transistor TR1 is maintained in the on state. On the last of the cart machines of the cart rack 8 having broadcast its commercial the outputs from the pins 1 to 4 of the cart rack 8 return low. Thus, the input pins 1 to 4 of the first OR gate 19 go low, and accordingly, the output of the first OR gate 19 likewise goes low.
However, the RC timing circuit holds the input pins 3 and 4 of the second OR gate 20 high for the time constant, namely, ten seconds, thereby, the transistor TR1 is retained in the on state, and the tape recorder 10 continues to record, thus, recording the beginning of the programme immediately after the commercial break. In this way the end of the commercial break and the beginning of the next commercial break can readily easily be identified. On the output of the second OR gate 20 going low, the transistor TR1 is switched off thereby switching off the tape recorder 15. A low on the second OR gate 20 also interrupts the telephone line 18, thereby terminating the call to the speaking clock.
In order to verify that a commercial or commercials have been broadcast and the time at which the commercials have been broadcast, one can replay the tape to the appropriate time at which the commercials should have been broadcast and by listening to the tape with the commercials recorded thereon, verify that the commercial was broadcast, and also the time at which the commercial was broadcast can be verified.
The advantages of the invention are many. Firstly, verification of the broadcasting of a commercial at a particular time can be readily easily undertaken, and the length of time required to verify that a commercial was played is relatively low. One can fast forward through the tape to the approximate position where the commercial should have been broadcast, and then listen to the tape around the appropriate time. Additionally, the precise time at which the commercial was broadcast can be verified. Furthermore, the cost of the apparatus according to the invention is relatively low.
All that is required is a relatively low cost cassette tape recorder and the relatively low cost control circuit. Additionally, no training is required for an operator to use a standard cassette tape recorder and play back unit.
In practise, it is envisaged that since each commercial break on average would last approximately three minutes, and, in general, there are approximately three commercial breaks per hour, a ninety minute tape would last for approximately ten hours.
The invention is not limited to the embodiment hereinbefore described which may be varied in construction and detail.
