BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to an arrangement for selecting titles from storage media respectively containing a number of recording titles in a magazine, particularly of CD's in CD boxes containing a plurality of CD's, the storage media bearing a list of the recording titles they contain, and a playback device being provided.
Coin-operated jukeboxes that have a CD magazine as well as a list of titles and a selection keyboard are found in a number of restaurants. After the deposit of coins and operation of the selection keyboard, the corresponding CD's are removed from the magazine, and the selected titles are played. Diverse devices for playing back selected titles are known (see, for example, DE-OS 3,922,721).
In a similar manner, in the interim there are also CD's, i.e. optical disks, that are housed in so-called CD boxes. If certain titles of these CD's are to be played, they must be, as before, selected or entered in a relatively involved manner. According to a first alternative, in a known way a selection keyboard having visual title information is operated.
The second alternative provides for the entry of a code. In this instance, the user must first determine a code associated with the desired recording title. Subsequently the code corresponding to the relevant CD must be entered, then usually a further two- or three-character code and, finally, usually a two-character title code. This means that, in total, at least a five-character code must be used. Should a plurality of recording titles be entered at one time in order to establish a playback sequence at the outset, this procedure proves involved and prone to errors, since the effort involved in entry is considerable.
The use of visual or bar codes is known to anyone in the area of retail, and particularly department stores, for entering the type of good and the sale price.
A CD handling system has also already been developed that permits the management and registration of CD's and their location by utilizing bar codes (see "Discover" brochure of the firm of Playsafe Monitoring Limited, Bath, Great Britain).
SUMMARY OF THE INVENTION
The object of the invention is to permit recording titles to be selected from a number of storage media in a magazine, particularly CD's, in a simple manner.
This object is accomplished according to the invention by the
arrangement according to the invention which permits the selection of titles from storage media in a magazine respectively containing a plurality of recording titles, particularly CD's in CD boxes containing a plurality of CD's. The storage media bear a list of the recording titles they contain, and a playback device is provided. The arrangement encompasses titles selected from the respective storage media, selected recording titles, playback device, the read codes being supplied to the decoding device, and visual codes that are respectively associated with the individual recording titles of the storage media and can be read by the light pen.
Through the provision of the visual bar code and the decoding device in the playback device, according to the invention, the selection of the desired recording titles is very simple. For the selection procedure, the light pen need merely be taken and drawn across the desired titles, i.e. their visual code, i.e. the selection is completely integrated into the visual title search. The read visual codes are then transmitted by way of a line or by means of remote transmission to the decoding device, from which the selected recording tiles are transmitted to the playback device for playback operation. In this way the operating expenditure for an operator is reduced to a minimum, namely to the actual selection and only the input of a playback command (scan of the title code). Playback, particularly of pieces of music, is in this way not associated with work, and rather means pure enjoyment.
Of course, the playback media need not be only CD's. These can also be, for example, records, cassettes, diskettes, etc. The recording titles can also includ
