In the present embodiment,
Be provided with input/output port 108 on processor 101, described input/output port 108, for connecting the interface of external unit, is realized and the data transmission of external unit and the transmission of control command.Described digital Audio Broadcasting System also comprises video drive 107 and video output 105.
Described instrument information data file can provide together along with the distribution of music album, or leaves special supporting website in and mate and downloaded for off-line or use online by the user.
Below in conjunction with the drawings and specific embodiments the present invention will be further explained explanation.
Fig. 1 is the digital Audio Broadcasting System circuit block diagram of embodiments of the invention, as shown in Figure 1, in the present embodiment, digital Audio Broadcasting System of the present invention comprises the parts such as processor 101, data-carrier store 110, button or touch screen 109, input/output port 108, video drive 107 and video output 105, display driver 106 and liquid crystal display 104, audio decoder 102 and audio frequency output 103.
The function of each several part or effect are as follows:
Data-carrier store 110 can be various ways, as SD card, USB flash disk, portable hard drive, FLASH etc., be mainly used in storing digital audio file and be song and with the instrument information data file of song coupling.
Button or touch screen 109 are input equipments, by button and touch screen, can complete various menu operations, input information and function and select.
Input/output port 108 is the interfaces that connect external unit, realizes and the data transmission of external unit and the transmission of control command.
Principle of work and the process of the described digital Audio Broadcasting System with musical instrument position display function are as follows:
At first, need to be according to concrete orchestration and the performance situation of each song, correspondingly write the instrument information data file, comprise musical instrument title for showing or picture pattern, musical instrument illustrated position, playing technique, and the data file of the information such as time parameter that musical instrument strikes up, stops to play, playing technique changes.For the musical instrument title that shows or picture pattern, musical instrument illustrated position, playing technique, and musical instrument strikes up, stops the time parameter of performance, playing technique change etc., these information are referred to as instrument information in the present invention, the data file formed by instrument information, be referred to as the instrument information data file in the present invention.Described instrument information data file can provide together along with the distribution of special edition, can be in advance with the song coupling after be stored in the data-carrier store of described digital Audio Broadcasting System extraction when playing music, perhaps leave special supporting website in and connect described websites by the user by input/output port 108 and mate and downloads and be stored in data-carrier store 110 for off-line, or in this locality, do not store use online.The process of coupling is as follows: after connecting internet when described digital Audio Broadcasting System by input/output port and entering supporting website, system is extracted comparing in the feature of the song in data-carrier store and website instrument information database automatically, such as can and mating corresponding instrument information according to information searches such as the title of song, affiliated special edition, performing artist, playing duration, mate the instrument information data file that suitable rear download chooses and be stored in data-carrier store.The user also can use the PC online, by supporting application program, is mated.Like this, by the musical instrument of set to participate in playing starts or stop to play and playing technique changes time parameter, musical instrument location parameter etc. in advance, along with the broadcasting of music synchronously starts to show or stop showing musical instrument title or picture pattern, musical instrument illustrated position, playing technique etc. in good time, thereby realized purpose of the present invention.
After song has mated the instrument information data file, described digital Audio Broadcasting System is when starting to play this song, processor 101 recalls the instrument information data file be complementary with this song simultaneously, the layouts that make the dim demonstration of liquid crystal display 104 all participate in the musical instrument of performance by display driver 106 are the musical instrument illustrated position, also can make video output 105 be connected to dimness on remote data indicator by video drive 107 and show the musical instrument illustrated position.
In whole music process, processor 101 obtains data by recalling described instrument information data file, constantly compare the time parameter that musical instrument starts and stop performance, playing technique change, when reproduction time arrives those musical instruments and strikes up, just according to location parameter, in the position of liquid crystal display 104 correspondences, light title or the picture pattern of musical instrument, and display text explanation playing technique, the change of playing technique also will be made corresponding change according to time parameter; And, when reproduction time arrival musical instrument stops playing, it is dimmed that the musical instrument that stops playing just extinguishes, cancel the explanatory note of playing technique.
Also can enable at any time or stop musical instrument position display function by operation push-button or touch screen 109 when playing music.
Musical instrument position display function does not affect audio frequency and plays, processor 101 reads the song of choosing and is play later, realize digital audio decoding by audio decoder 102, DAB is converted into to simulated audio signal, then export 103 by audio frequency and realize audio output function, directly drive earphone or input as the source of sound of audio frequency power amplifier.
So until before playing end, processor 101 is constantly according to the temporal information of instrument information data file, light or extinguish title or the picture pattern of musical instrument, show or cancellation playing technique explanatory note, make user's listoning music on one side, on one side under the prompting of native system, be very easy to find out is that what musical instrument is being played, where tell the musical instrument of playing is in, see and adopt what skill and technique playing, allow the user experience at any time the characteristic of various musical instruments and the effect that multiple musical instrument is instrumental ensembled, the profound understanding magic of music, this all plays good effect for the interest and the level that improve music appreciating.
