Description

Realize the method for music DIY on TV

Technical field

The present invention relates to a kind of TV tech, especially a kind ofly can be implemented in the method for carrying out music editor on the television set, specifically a kind of method that realizes music DIY on TV.

Background technology

At present, the hommization of household electrical appliance, intelligent degree are more and more higher.Various advanced technologies have been penetrated into household appliance technical field, and the function of various automations is provided, for daily life has been brought convenience.The introducing of various automation equipments, the control of the aspects such as various amounts, degree and time in the also accurate life has improved people's quality of life.The image acquisition visual information that people show by television screen, but for common TV, shortage is to the function of the DIY (self-defined Do In Yourself) of TV, such as the self-defined of music and broadcast, as if too far away with common consumer's distance, this mostly is to carry out at personal computer.According to the knowledge of the applicant, still there is not the function that a kind of television set has music DIY at present.

Summary of the invention

The objective of the invention is at existing TV music function singleness or do not have the problem of music editting function, invent a kind of method that realizes music DIY on TV.

Technical scheme of the present invention is:

A kind of method that realizes music DIY on TV is characterized in that:

At first, utilize the buzzing function that carries the audio process chip on the TV SKD to realize the broadcast of music DIY;

Secondly, utilize the abundant screen display function of television set to provide the interface of user's music DIY to realize;

The 3rd, in the TV set software bottom, set up the correspondence table of frequency and scale and musical alphabet and frequency;

The 4th, set up in the above-mentioned correspondence table corresponding relation of button on the scale and musical alphabet and TV operation button or straighforward operation plate;

The 5th, the music that the user edited is stored in the memory device with the particular data form;

At last, from memory device, take out corresponding data and play in the time-delay mode by the audio process chip during broadcast according to corresponding relation.

Describedly be stored in music in the memory device for can revise music.

Described being stored in prestores the module music of practising revising usefulness for the user in the memory device.Beneficial effect of the present invention:

The present invention utilizes the built-in audio processing capacity of TV, allows prevailing user can realize experience to the DIY of song on the TV platform, further to reach the better mutual of man-machine interface, promotes the image and the class of product.

Description of drawings

Fig. 1 is a workflow diagram of the present invention.

Fig. 2 is the flow chart that makes up playback engine for music of the present invention.

Embodiment

The present invention is further illustrated below in conjunction with drawings and Examples.

As shown in Figure 1, 2.

A kind of method that realizes music DIY on TV is characterized in that:

At first, utilize the buzzing function that carries the audio process chip on the TV SKD to realize the broadcast of music DIY;

Secondly, utilize the abundant screen display function of television set to provide the interface of user's music DIY to realize;

The 3rd, in the TV set software bottom, set up the correspondence table of frequency and scale and musical alphabet and frequency;

The 4th, set up in the above-mentioned correspondence table corresponding relation of button on the scale and musical alphabet and TV operation button or straighforward operation plate;

The 5th, the music that the user edited is stored in the memory device with the particular data form;

At last, from memory device, take out corresponding data and play in the time-delay mode by the audio process chip during broadcast according to corresponding relation.

That is to say:

At first, accomplish that the self-defined of music must meet some requirements:

1, television set must carry the audio process chip, and this almost can satisfy in the television set on present market at present;

2, this audio process chip provides BEEP buzzing function, also provides this measuring technology based on most chip;

3, the OSD of television set (On Screen Display) has the interface interaction than horn of plenty, and for user interactions, dynamic editing is play;

4, provide bigger dictionary memory space, can provide by user's demand;

5, can provide dynamic editing download/upload, broadcast (realizing) by personal computer for Higher-end machines;

Five above conditions all can provide in the platform of present main flow TV business men easily, mainly are the treatment of details part that realizes.

With following be concrete steps and the principle that realizes.

1, television field frame processing section:

The basis that hardware platform provides software to realize, audio process chip be not always in the sound accompaniment of broadcast program.In specific implementation, can make the audio process chip be in programmable state, the input of front end invalid (promptly not playing the sound accompaniment of TV).Write specific frequency (being played the scale of music) to specific register then, suitably delay time (being played the beat of music), produce beautiful music.

2, the principle part of sound:

Common scale is made up of 7 basic sounds:

1， 2， 3， 4， 5， 6， 7

Represent promptly with roll call:

do， re， mi， fa， so， la， si

With 7 sounds and to make various combinations than the sound of the sound of their high one or several octaves, low one or several octave be exactly " tune ", the normal frequency range of using approximately is 16～4000 hertz in the music, and the most expressive frequency range approximately is 60～1000 hertz in voice and the instrumental music.

	The music frequency correspondence table
								C(1)	D(2)	E(3)	F(4)	G(5)	A(6)	B(7)
	Bass	131	147	165	175	196	220								247
Middle pitch								262	296	330	349	392	440	494
	High pitch	523	587	659	698	784	880								988
The Senior Two degree								1047	1175	1319	1397	1568	1760	1976

For convenience, the frequency of middle pitch c sound be can be regarded as a unit, the frequency of the c sound of ottava alta is exactly two units, and the frequency of re sound is 9/8 unit, and the ratio of the frequency of a pair of octave equals 2: 1, and musical alphabet is become following table with separately column of frequencies:

Musical alphabet	C	D	E	F	G	A	B	C
									Frequency	1	9/8	81/64	4/3	3/2	27/16	243/128	2

If simulate in computer, its function processing procedure that realizes a first song is as follows,

// broadcast the function code that happy birthday

int func_playsound(void)

{

unsigned FREQUENCY[]＝{

392，392，440，392，523，494，

392，392，440，392，587，523，

392，392，784，659，523，494，440，

698，698，659，523，587，523

}；

unsigned DELAY[]＝{

375，125，500，500，500，1000，

375，125，500，500，500，1000，

375，125，500，500，500，500，1000，

375，125，500，500，500，1000，

}；

int CIRCLE；

for(CIRCLE＝0；CIRCLE＜25；CIRCLE++)

{

Beep(FREQUENCY[CIRCLE]，DELAY[CIRCLE])；

}

return 0；

}

Suitable coefficient of every increase that also need be in DELAY time-delay in TV is because be difference to some extent for the benchmark of time-delay on different implementation platforms.

In addition,, can also carry out the edge creation of a large amount of other based on the fact that in TV, can realize self-defined playing back music, as: simple digital editor's (being scale) of song in TV, provided, delay time then playback, modification, storage; Realize playlist in TV, the user can freely select built-in song; In the TV start, realize the self-defined music of start; When being arranged, message or timed power on/off provide music tip to remind; Provide personal computer relevant tool software, can change specific download of songs, also can provide upload function or the like, fully the writing space that realization can free music DIY on TV the song that edits to TV.
