Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
Embodiment one
Fig. 2 is the flow chart for the audio-frequency information display methods that the embodiment of the present invention one provides, and the present embodiment is applicable to sound
The case where there are analog audio signal inputs in display system, this method can be executed by the playback equipment in audio system, tool
Body includes the following steps:
Whether step 101, playback equipment real-time detection have the analog audio signal of input.
Wherein, analog audio signal is one kind of audio signal, including the analog audio signal linearly inputted.Audio signal
It is the regular information of acoustic wave carrier with voice, music and audio.According to the feature of sound wave, audio can be divided into regular sound
Frequency and irregular audio.Wherein, regular audio is a kind of continuously varying analog signal, can be with a continuous curve come table
Show, i.e. analog audio signal.Illustratively, playback equipment can pass through included port (such as 2.5 millimeters or 3.5 millis in this programme
Rice earphone jack) receive analog audio signal input.Wherein, the device for issuing analog audio signal can be radio, hand
Machine or tablet computer etc..Playback equipment open after, to whether have analog audio signal input be measured in real time.
If step 102, the playback equipment detect the presence of the analog audio signal of input, intercept by the analog audio
The digital audio-frequency data of frequency signal conversion, and the digital audio-frequency data of the interception is sent to server to identify the number
The audio-frequency information of audio data.
Wherein, playback equipment passes through the Analog-digital Converter module being internally integrated and turns the analog audio signal of input in real time
Be changed to digital audio-frequency data, after playback equipment detects the presence of the analog audio signal of input, i.e., to pass through the simulation numeral
The digital audio-frequency data that conversion module is converted to is intercepted.Illustratively, time point is carried out first during interception
Selection preferably can choose initial point of the current time as interception.Illustratively, the time of interception segment setting can be
3 seconds, i.e. playback equipment intercepts the digital audio-frequency data that the duration is 3 seconds, after interception, by this 3 seconds continuous digital sounds
Frequency evidence is sent to server to identify the corresponding audio-frequency information of the digital audio-frequency data.Preferably, which includes sound
Frequency title, singer, duration and place grouping (album) etc..
Playback equipment and server carry out data interaction by network connection in this programme, can be mobile network's connection or
The WLAN connection realized by router.
Step 103, the playback equipment receive the recognition result that the server is sent, if to the digital audio-frequency data
It identifies successfully, then the playback equipment saves the recognition result to be shown.
Wherein, recognition result includes identify successfully and recognition failures, includes to service in recognition result if identifying successfully
The corresponding audio-frequency information of digital audio-frequency data of device feedback, playback equipment save the audio-frequency information.
The technical solution of the present embodiment, solves in audio system, and playback equipment can not show present day analog audio input
Audio-frequency information, be not easy to select by the audio of analog audio input the problem of playing on one or more playback equipment, it is real
The audio-frequency information that present day analog audio input is shown in audio system is showed.

Preset audio database carries out the identification of analog audio signal, and recognition result is saved.
Based on the above technical solution, it includes: institute that the playback equipment, which saves the recognition result to carry out display,
It states playback equipment and saves the recognition result into memory, and send the recognition result to controlling terminal to be shown.It is excellent
Choosing, which, which can also be, shows recognition result by the display screen of itself, or the mode of voice broadcast is taken to broadcast
Put the recognition result.
Based on the above technical solution, it intercepts by the digital audio-frequency data that the analog audio signal is converted and includes:
Periodically intercept the digital audio-frequency data converted by the analog audio signal.
Based on the above technical solution, further includes: if to the digital audio-frequency data recognition failures, the broadcasting
Equipment intercepts the digital audio-frequency data converted by the analog audio signal again, and the digital audio-frequency data of the interception is sent out
It send to server and identifies the audio-frequency information of the digital audio-frequency data.Wherein, playback equipment, which is worked as, detects analog audio signal
After input, that is, start digital audio-frequency data that the interception of automated periodic is converted by the analog audio signal for being sent to clothes
Business device is identified, until identifying successfully.Preferably, after can also be the identification instruction for receiving controlling terminal, start the period
The interception digital audio-frequency data of property is to be identified until identifying successfully.It identifies successfully and after certain preset time value,
If playback equipment continues to test the input of analog audio signal, again automatically interception digital audio-frequency data to be identified,
If recognition result is identical with the audio-frequency information of precedence record, stop interception movement；If recognition result is different, this is recorded most
The audio-frequency information newly recognized.
