Definitions

  • This invention relates to a recorded message audio delivery system for use by an individual listener.
  • Such devices have improved the form of presentation somewhat in that visitors may proceed through the exhibition of their own speed and, to an extent, may choose their route. However, it is still not possible for them to choose to hear specific information about a particular exhibit, nor is it possible to program different language versions of a tour alternately on the same device. Thus, in at least some of these systems, the user is not able to choose the desired message, and the number of messages per area is typically limited to one which covers the entire area including multiple exhibits. Such message may be too long for the convenience of the user or may lack detail. Although it has not been possible for a listener to choose to hear any one message in the language of his pre-selected choice, at least one attempt has been made directed towards solving this problem.
  • the inventor moreover, appreciated that the increased cost in production of a large number of discrete messages and provision of receivers having tuners for listener selecting a message by entering a number might be offset by the provision of receivers which might each be programmed to receive messages in only one language chosen by the listener and reprogrammable to another language as required. If each receiver is capable of such versatility the actual cost of equipment may be reduced to a minimum. Still further the inventor appreciated that the cost of the equipment might be reduced still further by storing the messages for transmission in a storage medium which does not need moving into different positions to play the messages. Thus messages may retrieved with negligible wear and tear and negligible risk of malfunction. Thus the inventor envisaged storing the messages in digitized form on a computer chip.
  • a system for delivery of prerecorded messages in response to selection by a listener comprising; recorded messages stored in computer memory, different messages in one language being associated with a message identification datum and translations of any one message being associated with the message identification datum for said any one message; and each translation of any one message being associated with the message identification datum for said any one message; a transmitter settable to transmit each message in one language on separate non-interfering frequencies in a locality cell and to transmit translations of each message on separate non-interfering frequencies; at least one receiver programmable to receive transmitted messages in one language, and reprogrammable to receive transmitted translated messages in another language, by allocation of a set of reception frequencies for the receiver corresponding to the transmission frequencies for the messages or for translated messages in said other language; and manually operable selection means to select a receiver setting whereby a reception frequency is manually selectable by the listener in accordance with message identification indicia.
  • the power of the transmitter for practical purposes be sufficiently low as to avoid interference by transmissions produced using the system
  • the system maps that number to the transmitter frequency which contains the desired message in the desired message in the desired language. Two users, desiring the same message but in different languages, would enter the same message number but would receive the respective messages on two different frequencies.
  • the system may transmit on a power low enough to allow, when a large number of messages are involved, frequency to be reused within the confines of the environment.
  • a German speaking visitor, a French speaking visitor and an English speaking visitor will be referred by way of example but it will be appreciated that many other languages may be involved and the number of such languages is mainly dictated by demand and expense.
  • an art gallery is exemplified the system is utilizable for many other environments some of which will be discussed briefly below.
  • the FM band is presently attractive for use in the invention for regulatory and economic reasons. It includes many other bands than the FM commercial broadcast band (88.1 - 107.9 MHz). In the near future, it is envisaged that it may be attractive to produce systems above 1 GHz - eliminating many system issues (interference, frequency reuse, number of channels, etc.). If the FM band is to be used, conflict with other channels may be avoided by being able to use locally unassigned channels, i.e. the system will not be overpowered by local channels but may operate on an out of town channel because it will be weak relative to the immediate vicinity of the transmitter. Lower power operation may limit the reception range of the particular message aiming to keep it within the confines for the museum.
  • the visitors to the art gallery may be each provided with an FM radio receiver, hereinafter referred to as a "wand".
  • a wand In most environments, such as the exemplified art gallery tour the wand would be battery powered so that there are no trailing wires.
  • the wands are adapted to receive transmissions from an FM transmitter operating at sufficiently low power so as not to interfere with any commercial broadcasting station and, in some countries, at sufficiently low power so as not to contravene any regulations concerning interference with commercial broadcasting.
  • Discrete prerecorded messages in each language may be stored in digitized form on a computer chip.
  • This form of storage may have at least two distinct advantages over tape, or other recordings.
  • the transmitter retrieves messages from the chip and transmits retrieved messages on carefully selected pre-chosen non-interfering frequencies as will be further discussed.
  • Each exhibit in the gallery or other museum or environment may be provided with a separate message in each of the languages to be used and each exhibit may be identified to the visitor by an identification mark which is conveniently a number. This identification mark may also be used to identify messages relating to that exhibit and translations of that message language of the message.
  • Each wand is programmable to any of the available languages.
  • the programming of each wand is changeable and may be carried out on site.
  • a unit is provided to carry out the functions of battery charging and programming, so that a visitor may be provided with a charged wand custom programmed to receive the language of his choice.
  • programming and charging are functionally separate tasks and their provision within one unit is for convenience only.
  • the visitors may wander at will among the exhibits, listening to information only when they wish it and relating to the specific exhibit or a small group of exhibits in which they are interested. Moreover, the information will be provided in a language which they may understand.
  • each one of them may activate a selector marked for #6 on his wand.
  • Each wand will receive a similar message but in a different language and a message on separate non-interfering frequencies.
  • the choice of the non-interfering frequencies is deliberately chosen as the transmitting frequencies for similar messages in different languages at the same location.
  • the transmitting frequencies for different messages in the same language should also be non-interfering . From exhibit #6 it is not necessary to visit exhibit #7. The visitor may go forward sequentially or non-sequentially or retrace his tracks to an earlier exhibit which interested him.
  • the reverse problem i.e. potential interference of the system transmissions by commercial radio
  • the inventor has envisaged solving this problem by means of blocking reception on the frequency when interference occurs.
  • a system transmission may be accompanied by an identification signal for the transmission. If a non-identified transmission is detected reception may be blocked. This will have the effect of also blocking the system transmission but it is believed this is less objectionable than garbled transmission.
  • the problem may substantially be avoided by suitable choice of frequencies.
  • FM frequencies are that reception may be less impeded by obstructions between the transmitter and receiver than is the case when using AM frequencies or infrared beams. In any case infrared beams are obstructed by sunlight if used out of doors.
  • FM frequencies may make it convenient to operate the system on a cellular basis somewhat similar to the basis on which cellular telephones operate. As visitors move from one cell to another frequencies may be reused for different messages. Since visitors may actuate selectors which do not correspond to exhibit indicia, it is wise to block reception on any frequencies associated with these selectors.
  • the wand is programmed to receive messages on frequencies 40, 45, 509, 55 and 60 but only four recorded messages corresponding to exhibits 1, 2, 3 and 4 are available on frequencies 40, 45, 50 and 55, reception may be blocked on frequency 60.
  • programming means may be provided to program frequencies of zero or the like to correspond to all selector positions to which a message frequency is not assigned.
  • the selectors of each wand are preferably stationary pressure sensitive selectors to minimize wear due to moving parts.
  • the wand is conveniently designed to include a contact portion having access means for battery charging and for programming. The plug portion may be plugged into a socket of charging/programming bank for storage and for distribution.
  • the charging/programming bank may be located at any convenient location, but is conveniently near to a visitor entry zone. It may be designed as a self-serve distribution point for wands from which visitors select a wand when they enter and deposit it when they leave. Supervision will be necessary to supervise the appropriate programming of wands. However, if no wand is located in a socket marked for a desired language, it should cause very little delay to take a wand from another socket and reprogram it as desired.
