Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.It is understood that specific embodiment described herein is used only for explaining the present invention, but not limitation of the invention.It also should be noted that, for the ease of describing, accompanying drawing illustrate only part related to the present invention but not entire infrastructure.
Embodiment one
The flow chart of the audio-frequency information display packing that Fig. 2 provides for the embodiment of the present invention one, the present embodiment is applicable in audio system and there is the situation that simulated audio signal inputs, the method can be performed by the playback equipment in audio system, specifically includes following steps:
Step 101, playback equipment detect whether the simulated audio signal of input in real time.
Wherein, simulated audio signal is the one of audio signal, including the simulated audio signal of linear input.Audio signal is the regular information of acoustic wave carrier with voice, music and audio.Feature according to sound wave, can be divided into audio frequency rule audio frequency and irregular audio frequency.Wherein, rule audio frequency is a kind of continuously varying analog signal, can represent with a continuous print curve, i.e. simulated audio signal.Exemplary, the port (such as 2.5 millimeters or 3.5 millimeters of earphone jacks) that in this programme, playback equipment can pass through to carry receives the input of simulated audio signal.Wherein, the device sending simulated audio signal can be radio, mobile phone or panel computer etc..After playback equipment is opened, to whether having simulated audio signal input to detect in real time.
If the described playback equipment of step 102 detects the presence of the simulated audio signal of input, then intercept the digital audio-frequency data changed by described simulated audio signal, and the digital audio-frequency data of described intercepting is sent to server to identify the audio-frequency information of described digital audio-frequency data.
Wherein, the simulated audio signal of input is converted to digital audio-frequency data by the Analog-digital Converter module being internally integrated by playback equipment in real time, after playback equipment detects the presence of the simulated audio signal of input, namely the digital audio-frequency data being converted to by this Analog-digital Converter module is intercepted.Exemplary, first time point is selected in intercepting process, it is preferred that current time can be selected as the initial point intercepted.Exemplary, the time intercepting fragment setting can be 3 seconds, namely playback equipment intercepts the digital audio-frequency data that the persistent period is 3 seconds, after intercepting, by audio-frequency information corresponding to identify this digital audio-frequency data for this continuous print digital audio-frequency data transmission in 3 seconds to server.Preferably, this audio-frequency information includes audio frequency title, singer, duration and place packet (special edition) etc..
In this programme, playback equipment and server are connected by network and carry out data interaction, it is possible to be mobile network's WLAN connection of connecting or being realized by router.
Step 103, described playback equipment receive the recognition result that described server sends, if to described digital audio-frequency data identification success, then described playback equipment preserves described recognition result to display.
Wherein, recognition result includes identifying success and recognition failures, if identifying successfully, then including the audio-frequency information that the digital audio-frequency data of server feedback is corresponding in recognition result, this audio-frequency information is preserved by playback equipment.
The technical scheme of the present embodiment, solve in audio system, playback equipment cannot show the audio-frequency information that present day analog audio frequency inputs, the problem being not easy to select to play the audio frequency that analogue audio frequency inputs on one or more playback equipment, it is achieved that show the audio-frequency information that present day analog audio frequency inputs in audio system.
On the basis of technique scheme, playback equipment can pass through self to carry out the identification of digital audio-frequency data, and non-sent is identified to server.Wherein, when the higher calculation processing power of the configuration of playback equipment is stronger, self preset audio database can be passed through and be simulated the identification of audio signal, recognition result is preserved.
On the basis of technique scheme, described playback equipment preserves described recognition result and includes to display: described playback equipment preserves described recognition result to internal memory, and sends described recognition result to controlling terminal to display.Preferably, this playback equipment can also be by the display screen display recognition result of self, or takes the mode of voice broadcast to play this recognition result.
On the basis of technique scheme, intercept the digital audio-frequency data changed by described simulated audio signal and include: periodically intercept the digital audio-frequency data changed by described simulated audio signal.
On the basis of technique scheme, also include: if to described digital audio-frequency data recognition failures, then described playback equipment intercepts the digital audio-frequency data changed by described simulated audio signal again, and sends to server the digital audio-frequency data of described intercepting to identify the audio-frequency information of described digital audio-frequency data.Wherein, playback equipment, after simulated audio signal input being detected, namely starts automatically periodically to intercept the digital audio-frequency data changed by described simulated audio signal and is identified for being sent to server, until identifying successfully.Preferably, it is also possible to be after the recognition instruction receiving and controlling terminal, start periodically to intercept digital audio-frequency data to be identified until identifying successfully.Identify successfully and after certain preset time value, if playback equipment continues to detect the input of simulated audio signal, then again automatically intercept digital audio-frequency data to be identified, if recognition result is identical with the audio-frequency information of precedence record, then stop intercepting action；If recognition result is different, then record this up-to-date audio-frequency information recognized.
