Abstract
An electronic monitoring system for video cassette and games hire has a cabinet in which the video cassettes/games J are stored such that their unique electrically conductive labels E interface correctly with PCB mounted electronic monitoring equipment L. The cassettes/games are positioned in slots, moulded into cassette trays which ensure that the spring loaded contact pins D always touch the labels. Removal or insertion of the cassettes/games is monitored by a microprocessor which detects the absence time of the cassette/game and compares the time against a preset standard and records hire periods accordingly. Hire information is accessed via a RS232 serial interface either locally, or remotely using a PCB mounted modem facility. <IMAGE>
Description
ELECTRONIC MONITORING SYSTEM FOR VIDEO CASSETTE HIRE
This invention relates to an electronic monitoring system for video film cassette and computer game hire.
The hiring of video films for home entertainment is now a well established industry. The films are sold to video hire shops by a distribution network of independent suppliers at costs of up to 85 per film (1991 economics). When purchased the films are hired to the general public at an agreed rate for a set period of time. The control exercised over the hiring of films is largely dependent upon the honesty of the video shop employee and is based on either manual input to a computer or a hand written recording system.
Moreover, the cost of the film to the video hire shops can inhibit the sale of some films as the video shop owner is expected to assess the hire potential of a film, which has already been made, prior to having any reliable market feed back. Both of the above situations would be improved if the film owner or the distributor was able to distribute the films free of charge and subsequently share in the hire charges made for the film with the assurance that the cassette hire could be reliably monitored.
According to the present invention there is provided a uniquely coded electrically conductive label which is fixed to the outside of the video cassette by means of an adhesive, a set of spring loaded terminal pins which connect the conductive label to the electronic circuitry which in turn monitors the presence of the video cassette in a specially designed cassette storage cabinet. Figure (1) shows the block circuit diagram of the invention. The circuit consists of a microprocessor, item A, which controls the system. Under software control, the microprocessor accesses each cassette, item J, sequentially to determine if the cassette is present within the cabinet.
Access to each cassette is made via a multiplexer, item B, and a shift register, item C which reads the switch state of each individual terminal pin, item D. The terminal pins are mounted in a contact block, item K, which in turn is secured to a PCB, item L. When the cassette is present within the storage cabinet, the terminal pins, item
D, interface with the electrically conductive label, item E, and electrical contact is made. The transistor, item F, which is also controlled by the microprocessor is powered up and accordingly each
ELECTRONIC MONITORING SYSTEM FOR VIDEO CASSETTE HIRE terminal pin assumes a switch state of either high or low dependant upon the formation of the coded electrically conductive cassette label. The shift register, item C reads each terminal pin independently and a unique binary code is transmitted back to the microprocessor, item A, for analysis.The binary code is transmitted serially using a clock generated by the microprocessor, item G and the multiplexer, item B. When the information has been analysed by the microprocessor, data is stored in the RAM chip, item H, for retrieval at a later date via a RS232 serial interface, item M.
When the cassette is not present within the storage cabinet, the terminal pins, item D, cannot interface with the electrically conductive label, item E, and electrical contact cannot be made. The transistor, item F, which is also controlled by the microprocessor is powered up and as electrical contact has not been made with the electrically conductive cassette label each terminal pin assumes a switch state of high. The shift register, item C, reads each terminal pin independently and a binary code is transmitted back to the microprocessor, item A, for analysis. As this binary code is allocated for all cassette stations which do not have cassettes present, then the microprocessor is able to determine that a cassette is missing. The binary code is transmitted serially using a clock signal generated by the microprocessor, item G and the multiplexer, item B.When the information has been analysed by the microprocessor, data is stored in the RAM chip, item H, for retrieval at a later date via a RS232 serial interface, item M. In order for the system to be able to differentiate between cassettes, each cassette is individually coded by forming the electrically conductive label into unique electrical switch states. As stated previously, the microcontroller electronically accesses each cassette label sequentially. The label is read digitally and the code is sent back to the microprocessor by means of serial communication. When the tape is removed from the cabinet the electronically conductive tape will not be present to allow the correct digital code to be sent back to the processor. As such the cassette will be logged as potentially "on hire".The microprocessor is programmed to access each individual cassette at set intervals of time and this technique allows the duration of the hire to be monitored. For example, if the cassette
ELECTRONIC MONITORING SYSTEM FOR VIDEO CASSETTE HIRE is logged as on hire over the specified duration, then the hire is recorded in the processor RAM memory chip. To be more specific, if a cassette is said to be on hire when detected as absent from the storage cabinet for periods in excess of say 12 hours and the cassettes are monitored at intervals of say 10 minutes, the processor will be able to detect the availability of the cassette, add up the periods of potential hire and record actual hires accordingly.
The microprocessor software therefore not only controls the monitoring of each cassette, but also controls the period classed as an actual hire. Under these circumstances it is possible to adjust the actual hire periods to suit each application. For example, if cassettes were to be played in the shop rather than at home then the actual hire duration would need to be near to the play time of the tape. Thus by minor adjustment of the software, sufficient control can be maintained. Additionally, the software can also be adjusted to accommodate weekend hire periods using the real time clock.
A specific explanation of the invention follows.
Figure 2 shows a front elevation of a typical cassette storage cabinet.
A photograph has also been included for clarity. The storage cabinet, item N, not only provides efficient storage of the cassettes, item J, in a relatively dust free environment, but also carries the PCB assembly which monitors the presence of the video cassettes. In this example, the cassettes are stored vertically and are guided into position by means of two plastic moulded trays, item P, situated at the top and bottom of the cassettes. The guide trays are an essential part of the design as they guide each video cassette into contact with the spring loaded terminal pins which link the conductive label to the electronic monitoring circuit. Positional accuracy is important as the terminal pins must locate correctly on the conductive label so that the switch code can be read correctly. There is no limit to the number of cassettes that can be stored in this way. Additionally, there is no technical reason why the cassettes could not be stored horizontally if required. Figure 2 and the photograph relate to films that will be used in the travel industry, but it should be noted that this invention is not limited to any one area of use.
ELECTRONIC MONITORING SYSTEM FOR VIDEO CASSETTE HIRE figure 3 shows enlarged views of the storage cabinet. Figure 3a is an enlarged view of a cassette stored vertically, showing the top and bottom guide trays, whilst figures 3b & 3c are sections through the cabinet (looking downwards) which show in detail the method of guiding and latching of the cassette to the terminal pins. It can be seen that the cassette is guided into position by guide rails that have been moulded into the guide trays and latching of the cassette is achieved by means of a clip feature also moulded into the guide rails.
The spring loaded terminals provide the force required to latch the cassette to the clip feature in addition to also providing sufficient force to maintain good electrical contact with the conductive label.
Figure 3b shows a cassette in the non-latched position, whilst figure 3c shows a cassette in the latched position with the terminal pins compressed.
Figure 4 is a section through the cabinet showing the cassette bar code label in contact with the terminal pins. The block circuit diagram for the electronic monitoring system can be seen in figure 2.
It can be seen that the cassette can be loaded in either vertical direction as electronically conductive labels have been provided at the top and bottom of the cassette to ensure that electrical contact can be made in either position. When the label is in contact with the terminal pins, the cassette unique code can be read by the electronic monitoring circuit. Each label is unique and is based on simple electrical switch signals. Each label is arranged to give a unique switching arrangement by either making or breaking contact. By this means a digital signal can be achieved as each of the switch positions will be read as either high or low. This code is then transmitted to the microcontroller for analysis. Obviously, if the cassette is not in position, electrical contact cannot be made and the cassette will be recorded as potentially on hire.As the electronic circuit continues to monitor each position within the cabinet, each potential hire period will be added together until the pre-set limit has been exceeded and the cassette will be logged as on hire.
Figure 2 shows the block circuit diagram for the system. The electronic circuit has been designed to detect the presence of individual video cassettes in a specially designed storage cabinet.
ELECTRONIC MONITORING SYSTEM FOR VIDEO CASSETTE HIRE
As previously stated, this is possible as each cassette is individually coded by forming electrically conductive tape into unique switch coded labels and attaching them to the casing of the video cassettes.
The system basically consists of a microcontroller which accesses each cassette station sequentially via a number of multiplexers and parallel to serial shift registers. On power up the microcontroller software controls routine access to each cassette station sequentially.
The access routine is repeated systematically whilst the power supply is maintained. In situations where the power supply is interrupted, the microcontroller records the date, time and duration of the interruption. The information to and from the microcontroller is transmitted serially as each cassette station is accessed via a multiplexer. The multiplexers interface with parallel to serial shift registers at each cassette station and the shift register, via transistors, allows each terminal pin to be interrogated independently. As each cassette carries a unique code label, made of electrically conductive tape, and the terminal pins act as switches, a unique code can be identified for each tape. The code is then transmitted back to the microprocessor and compared against the previous memory settings and base information.As previously stated, hires are then recorded in the processor memory and this information is accessed periodically via a RS232 serial interface to a portable computer. When the hire information is down loaded into the computer, a more detailed assessment of hires can be made and the necessary invoices prepared. A facility for modem interrogation has been included for use at a later date. Power supply to the system is via a mains input which incorporates a voltage transformer capable of maintaining a constant voltage.
Figure 6 shows the electrically conductive label, the way that the label interfaces with the terminal pins and the method of retrieving the code from the label. Two different labels are shown in order to explain the method by which the labels are uniquely coded. 7 terminal pins are shown but it should be noted that there is no limit to the number of pins that can be used as the number of pins directly affects the number of codes that can be generated. The coding is based on binary coding and as such 7 pins would give a total of 64 combinations, assuming that one of the 7 pins is held as a permanent
ELECTRONIC MONITORING SYSTEM FOR VIDEO CASSETTE HIRE ground plane. Two figures are therefore shown, figure 6a shows a label with 3 contacts connected to ground whilst figure 6b shows 6 contacts connected to ground.Unique codes are generated as follows :
In figure 6a the microprocessor has accessed a single cassette station via a multiplexer and the cassette station shift register and transistor have been switched on. When the terminal pins are not in contact with the the label, the voltage of all of the terminal pins is held at 5 volts. When the terminal pins come into contact with the label, pins 1, 2 and 3 are switched to ground, whilst pins 4, 5 and 6 remain at 5 volts as they do not come into contact with the conductive label.
Note that pin 7 is reserved as a permanent ground plane. The shift register therefore reads the following code:
Pin No 1 2 3 4 5 6
Code 0 0 0 1 1 1
Using the clock signal, the shift register sends this code back to the microprocessor for analysis prior to recording the hire in the memory device.
In figure 6b the microprocessor has again accessed a single cassette station via a multiplexer and the cassette station shift register and transistor have been switched on. When the terminal pins are not in contact with the label, the voltage of all of the terminal pins is held at 5 volts. When the terminal pins come into contact with the label, pins 1, 2, 3, 4, 5 and 6 are switched to ground. Note that pin 7 is again reserved as a permanent ground plane. The shift register therefore reads the following code:
Pin No 1 2 3 4 5 6
Code 0 0 0 0 0 0
Using the clock signal, the shift register sends this code back to the microprocessor for analysis prior to recording the hire in the memory device.
ELECTRONIC MONITORING SYSTEM FOR VIDEO CASSETTE HIRE
Using the above examples it can be seen that with 6 pins, 64 different combinations can be accessed and obviously as the number of pins increase, the number of unique codes available increases also.
