DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a music-playing system for a motor vehicle provided with an antenna and a receiver, the device encompassing an input unit for operating the receiver, a display connected to the receiver and at least one loudspeaker.
As mobility increases, more and more hours are spent in motor vehicles. Accordingly, requirements placed on the equipment of the vehicle are becoming higher: on the one hand, the time spent in it is to be as pleasant as possible and, on the other hand, time is to be utilized as well as possible. Another objective is to keep costs as low as possible.
Diverse music-playing devices exist for listening to music. As always, car radios offer the widest range of possibilities for receiving and playing pieces of music conventionally transmitted by transmitters. So that passengers can listen independently of broadcast programs, or hear specific pieces if desired, many motor vehicles are alternatively or additionally equipped with cassette players or, in recent times, with CD players. The operation of these devices, however, involves the changing of cassettes or CDs, which can mean undesired disturbances, effort and distraction during driving.
In GB-A-2 185 361 a terminal is described which is designed for professional in-home use, and is connected by an interface to a transmission line via cable or satellite. The information specified for the terminal includes music, but also digital, telefax, telex and videotex information. The terminal has a memory for the received information, a central unit and an output and display unit. The connections to stationary devices are provided in the form of cables or lines, while the connections to mobile devices such as hand displays are realized via radio, e.g. infrared remote transmission. The known terminal is intended to permit the transmission of data at low rates, thus saving transmission costs.
From WO-A-92/01342, a coin-operated jukebox is known which has a coin unit, a display, an input keyboard and at least one loudspeaker. The jukebox is connected via a remote data transmission line to a central music store; the remote data transmission line is suitable for transmitting audio information, and is preferably an ISDN line. Thus, the known jukebox itself does not contain a playback unit with the further corresponding, associated device units, but instead is connected to a central music store and can retrieve the desired information, that is, the selected pieces of music, from this store. Consequently, the equipment costs of the individual jukeboxes is reduced, and the scope of operational and maintenance work is smaller. A supply and an exchange of compact discs in individual jukeboxes are eliminated. This is only a requirement for the central music store, which can contain a considerably larger selection of music pieces than an individual jukebox. Correspondingly, the capacity of the central music store, which is advisably configured as a database, can be utilized better than that of an individual jukebox.
Further proposed in WO-A-92/01342 is the integration of this type of terminal unit into a conventional compact disc playback device, cassette player, television, etc., which can also be set up in private households.
SUMMARY OF THE INVENTION
The object of the invention is to create a music-playing system for motor vehicles which can be operated simply and, at the same time, permits playback of music pieces stored at a fixed location.
A music-playing system of the invention for a motor vehicle provided with an antenna encompasses a receiver, an input unit for operating the receiver, a display connected to the receiver and at least one loudspeaker. Furthermore, the motor vehicle is provided with a central unit and an output unit for transmitting commands and control signals. A music storage unit is provided which is advisably connected by a modem to one or a plurality of transmitters by way of a remote data transmission line suited for transmitting audio information. The receiver of the motor vehicle serve
