Fig. 2 is the flow chart of the television set karaoke Marking method that provides of the embodiment of the invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1 shows the structure of the television set karaoke marking system that the embodiment of the invention provides.
Karaoke resource acquisition unit 11 from USB storage that described television set is connected obtain the Karaoke resource, described Karaoke resource comprises former tone signal and the file of marking.
Wherein, when described Karaoke resource acquisition unit 11 obtains the Karaoke resource of described USB storage, be decrypted processing by corresponding with described USB storage encoding and decoding.
The television set karaoke marking system of the embodiment of the invention connects the USB storage of storage Karaoke resource by television set.
Wherein, USB storage is deposited the associated documents such as system file, AVI background paper, JPG background picture file, scoring background images file, scoring music file, scoring amusement sound of music program file, the television set KARAOKE digit score of the used encoding process of Karaoke.
In specific implementation process, when resource is played Karaoka in described USB storage storage, encrypt storage by respective coding, described television set reads the Karaoke resource of described USB storage according to respective coding.
When the user passed through the singing voice signal of MIC interface input, audio amplification unit 12 is imported the user by the MIC interface singing voice signal carried out audio frequency and amplifies.
Singing voice signal acquiring unit 13 is obtained the singing voice signal after audio amplification unit 12 amplifies.
AD conversion unit 14 is a digital signal with the analog signal conversion of the singing voice signal that described singing voice signal acquiring unit 13 is obtained.
Former tone signal that processor 15 obtains described Karaoke resource acquisition unit 11 according to described scoring file and the singing voice signal after 14 conversions of described AD conversion unit are analyzed, and generate corresponding comparative analysis result.
For example, suppose that the DATA0 signal is the standard song data that television set reads from USB storage, the DATA1 signal is the singer's that obtains of television set song data. by being calculated, the isoparametric comparative analysis of signal frequency, phase place and amplitude in DATA0 and two data of DATA1 can draw the pitch correction data; By being calculated, signal time comparative analysis in DATA0 and two data of DATA1 can draw the melody correction data; Pitch correction data and melody correction data are shown on screen of TV set, make the singer can find out the gap of actual and standard room.
And, when being analyzed, the processing of also above-mentioned correction data being marked of the television set of the embodiment of the invention.
Comparing result Tip element 16 is given the user with the comparative analysis results suggest of described processor 15.
