Detailed Description Of The Invention
Below with reference to accompanying drawings embodiments of the invention are elaborated.
Before embodiment was elaborated, at first the header file to JPEG briefly introduced.
Fig. 1 shows the header file table in the jpeg file.
As described in Figure 1, in the header file table, only show the basic token (marker) of baseline jpeg, institute is underlined all to start with FF (hexadecimal).Wherein, mark 0xFFFE is used for mark COM territory, is used to write comment field, and its length is with two byte representations, and therefore, the variable-length in COM territory should be no more than 64K.
When the recorded voice file, use the 8K sample rate, it was two seconds that single channel, each sampled point adopt 16bit coding and recording time, under this condition recording substance was saved as the wav file, its file size is 32K.Therefore, when being embedded in such audio files in the COM territory, the length that can satisfy the COM territory fully is no more than the condition of 64k.In addition, if this recording substance of 2 seconds is stored as the audio files of other form of handling through overcompression, such as ogg, during the vorbit file, its size is 10K, much smaller than 64K.That is to say that when adopting the audio files of other compressed format, size is that the audio files of 64K can be corresponding to the recording substance of time span far more than 2 seconds.
In addition, generally speaking, the phrase that is used to explain the spot for photography comprises 2 words usually, such as " Beijing ", is approximately 1 second and say the needed time of this phrase " Beijing " with normal word speed, and promptly the time span of its recording substance is 1 second.As can be seen from the above, can will be embedded in the COM territory of header file fully, and satisfy the regulation of the length in COM territory less than 64K such as " Beijing " or the audio files (its size is less than 64K) that comprises more words.Here, the COM territory only is to be used for illustration, can also use other idle domain in the jpeg file, such as the reservation territory 0xFF02 among Fig. 1,0xFFBF.In the present invention, utilize above-mentioned characteristic to realize audio files is added in the idle domain of jpeg file just.
Following specifying with reference to Fig. 2 and 3 added audio files in the jpeg file process.This process is to implement in the equipment with Voice ﹠ Video disposal ability (hereinafter, being called the audio/video treatment facility).
Fig. 2 shows according to embodiments of the invention, audio files is added to the flow chart of the method in the jpeg file.In this embodiment, be example with audio files " Beijing.amr ", and specify as idle domain with the COM territory in the header file of jpeg file and how to utilize audio/video treatment facility 200 in jpeg file, to add audio files.Simple in order to illustrate, in the following embodiments, all describe as idle domain with the COM territory in the header file of jpeg file.Be noted that in an embodiment of the present invention, can also use other idle domain in the jpeg file, such as the reservation territory 0xFF02 among Fig. 1,0xFFBF.
As shown in Figure 2, in step S210, at first, obtain audio files " Beijing.amr " by audio/video treatment facility 200.In this step, audio files " Beijing.amr " can be the audio files that has write down that reads from audio/video treatment facility 200, also can be the audio files that the user obtains by recording.In addition, be noted that except the amr form that this audio files can also be the file that adopts other form, such as wav file, rm file, mp3 file, MP4 file or other audio file.
At step S220, obtain jpeg file by audio/video treatment facility 200.Equally, in this step, the jpeg file that is obtained can be the jpeg file that has write down that reads from audio/video treatment facility 200, also can be the jpeg file that audio/video treatment facility 200 is just being taken.
In step S230, audio/video treatment facility 200 adds audio files " Beijing.amr " in the COM territory in the header file of jpeg file.Below step S230 is described in more detail.Here, step S230 further comprises substep S231～S237.
At step S231, open jpeg file in read-write mode.Then, search mark 0xFFDA in the header file of JPEG, this mark is used to indicate scan line to begin.
After searching mark 0xFFDA, at step S232, the data that mark 0xFFDA is later comprise 0xFFDA, read in buffer storage to carry out buffer memory.
After the data later to mark 0xFFDA are carried out buffer memory, at step S233, file pointer is moved to the 0xFF of 0xFFDA, in jpeg file, write mark 0xFFFE, it is used for mark COM territory.The length of this mark is 2 bytes.Then, file pointer is moved two bytes, write mark " Place Voice " in jpeg file, its expression has audio files.The length of mark " Place Voice " is fixed as 11 bytes.In addition, also write mark extension length in jpeg file, it is used to indicate extension name length.The length of mark extension length is 1 byte.In addition, also write mark extension in jpeg file, it is used to write down extension name.In this example, because expansion .amr by name, and the length of .amr is 4, so the content that is write down among the mark Extension is .amr, its length is 4.Should be appreciated that, because different extension name has different length, so according to different extension name, the length of mark Extension is variable.
Need to prove that two bytes between mark " Place Voice " and the mark 0xFFFE are marked as Length, it is used for writing down the total length in COM territory.
Then, in step S234, open audio files beijing.amr, and calculate the size of this audio files in the readable mode of binary system.
After calculating the size of this audio files, at step S235, judge whether the size of this audio files surpasses preset value T=64k-(length of mark 0xFFFE)-(length of mark length)-(length of mark Place Voice)-(length of mark Extension length)-(length of mark Extension).Wherein, the length of mark 0xFFFE, length, " Place Voice ", extension length is constant.Particularly, the length of mark 0xFFFE is 2 bytes, and the length of Length is 2 bytes, and the length of " Place Voice " is 11 bytes, and the length of Extension Length is 1 byte.In addition, according to different extension name, the length of mark Extension is variable, and it generally is no more than 10.Therefore, this preset value is set to T=64k-26 usually.When the size of this audio files does not surpass this preset value, proceed to step S236.Otherwise this process finishes.
At step S236, beijing.amr reads in internal memory with audio files, writes jpeg file then.After writing audio files beijing.amr, more former 0xFFDA and later data are write jpeg file.
Subsequently, at step S237, calculate mark 0xFFFE, length, " Place Voice ", extension length, extension and audio files length and.Then, with the back of jpeg file pointer movement, above-mentioned length and (with two byte representations) are written among the length to 0xFFFE.
