Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to the technical field of audio equipment, and more particularly to a reproduction program for an audio system suitable for a multimedia system capable of reproducing a plurality of types of audio sources in the field of car audio and home audio.
[0002]
[Prior art]
Conventional audio systems have mainly been configured to control amplifiers, FM / AM radio tuners, compact discs (CDs), mini discs (MDs), and the like collectively with a single control microcomputer built in the main unit. The system tends to be unitized in order to cope with the complexity of the function and the multi-media reproduction of many types of audio sources.
[0003]
That is, the microcomputer is divided into a microcomputer built in the audio equipment of the main master unit and a plurality of slave units that reproduce various subordinate audio sources controlled by the master unit, and the microcomputer of the master unit is connected via a bus line. The product form of a so-called master / slave unit system in which a microcomputer of a slave unit is controlled and an audio source of each unit is selectively reproduced is increasing.
[0004]
For example, as shown in a simplified configuration diagram of a master slave unit system which is an example of the conventional audio system in FIG. 2, the microcomputer 1 of the master unit MU which is an amplifier unit has its input pin / output pin I ./O via the bus interface BUSI / F, the microcomputers MC1, MC2,... Such as radio tuners, CD players, cassette tape players, MD players, and CD changer players, which are slave units SU1, SU2. Is controlled by transmission and reception of control signals and the like by packet communication through the bus line BUS.
[0005]
[Problems to be solved by the invention]
With the diversification of audio sources such as AM / FM radio broadcasts, CDs, MDs, DVDs, cassette tapes, television broadcasts, and videos (audio means media sources in general including visual sources as well), what are the users? You may get lost in choosing whether to listen to In some cases, it may be desired to sequentially listen to various audio sources (including radio broadcasts and television broadcasts) loaded in a plurality of units.
[0006]
In particular, in the case of a car audio system, it is not preferable from the viewpoint of traffic safety to successively and finely operate the buttons of the audio system during driving when the user is lost in the above selection.
[0007]
SUMMARY OF THE INVENTION The present invention provides a reproduction program for an audio system in which an audio system compatible with a multimedia source for reproducing a plurality of types of audio sources including a television broadcast and a radio broadcast can be easily selected by a user using software. Is what you do.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a playback program for an audio system in which a microcomputer controls playback of a plurality of types of audio sources, wherein the microcomputer is currently selected from a plurality of types of audio sources. Mode selection means for selecting one of a single play mode for reproducing the audio source being selected or a newly selected audio source and a multi play mode for sequentially reproducing a plurality of types of audio sources, and automatically selecting the multi play mode. Multi-play means for controlling reproduction of the plurality of types of audio sources so as to reproduce the audio sources in a predetermined order or a random order for a predetermined time; and, during or after the end of the multi-play mode, an arbitrary audio source by operating a predetermined button. Single play mode To provide an audio system playback program to function as a playback audio source determination means for setting the.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of a reproduction program for an audio system according to the present invention will be described in detail with reference to a flow chart of the program in FIG. 1 taking the above-mentioned master / slave unit system as shown in FIG. 2 as an example.
[0010]
First, it is premised that the reproduction program of the present invention stores a program such as C language in a memory such as a ROM built in the microcomputer 1 of the main control of the master unit MU in an audio system such as the master slave unit system as shown in FIG. It is assumed that it is recorded as program data in a description language. That is, it is added in by the software of the microcomputer.
[0011]
A reproduction program for an audio system according to the present invention includes a plurality of types of audio sources by various reproduction devices such as a radio tuner, a CD player, an MD player, a CD changer, and a DVD player in which the microcomputer 1 is the slave units SU1, SU2,. (Radio broadcast, CD, CD changer, MD, DVD, etc.) This is a program for controlling the selective reproduction. When the power of the system is turned on, a scan play (single play or multi play) selection wait state is first set. The microcomputer 1 is provided with a single play mode for reproducing the currently selected audio source or a newly selected audio source from the plurality of types of audio sources, and a multiple play mode for sequentially reproducing the plurality of types of audio sources. Mode selection means H1 for selecting one of the modes, and playback control for automatically playing back the plurality of types of audio sources in a predetermined order or a random order for a predetermined time when the multi-play mode is selected. It functions as a multi-play means H2 and a reproduction audio source determining means (for example, pressing a scan button) H3 for setting a single play mode of an arbitrary audio source by a predetermined button operation during or after the end of the multi-play mode.
[0012]
That is, when the single play mode is selected by the mode selection means H1, the microcomputer 1 of the master unit MU activates the slave unit SU1 of the audio source selected immediately before or the audio source newly selected, and the microcomputer 1 operates. The microcomputer MC1 of the slave unit SU1 is controlled so that the audio source 15 is reproduced.
[0013]
On the other hand, when the multi-play mode is selected by the scan button by the mode selecting means H1, the microcomputer 1 of the master unit MU sequentially operates the slave units SU1, SU2,. As described above, the radio source play, the CD mode play, the CD changer play, the MD mode play, the DVD mode play, the other mode play, and the like are activated for a predetermined time, for example, 5 seconds to 10 seconds, and the audio sources 15, 16,. Of the slave units SU1, SU2,... Are controlled so as to reproduce the first part (for example, the touching part of the first music in the case of MD).
[0014]
After all the audio sources of the audio system have been reproduced for a predetermined time, the process returns to the scan play selection waiting state (RT).
[0015]
In general, the user determines a favorite audio source (for example, MD) during or after the end of the multi-play mode by the reproduction audio source determining means H3, and presses a predetermined button operation (for example, a scan button pressing operation). The setting moves to the single play mode.
[0016]
The automatic playback scan order of the slave units SU1, SU2,... Of the audio sources 15, 16,... Is not limited to a predetermined order, but may be a random order. A known random play program can be applied to the random scan play means.
[0017]
【The invention's effect】
Since the playback program of the audio system according to the present invention is configured as described above, the user determines, while confirming which audio source to listen to, by sequentially playing back a large number of audio source playback units in a short time. Therefore, it is not necessary to select and operate the player unit of each audio source one after another, so that it is possible to save labor for operation. In addition, especially in the case of car audio, the operability required for audio source selection is simplified, resulting in increased safety during driving.
[0018]
In addition, it can be added in by software of a microcomputer in an existing audio system for reproducing a plurality of types of audio sources, and can be realized at low cost.
