Using the above-mentioned network architecture, the embodiment of the present invention provides a kind of playback method of media file, as shown in Fig. 2, packet
It includes：
201, playback equipment receives media file, and media file includes first kind field and Second Type field, and root
Corresponding player is called according to first kind field.
After control point can be used UPnP protocol and be connect with playback equipment by DLNA server, control point can will need
Shared media file is sent to DLNA server, so that playback equipment obtains the media file from DLNA server.Wherein should
Media file includes the attribute information of media file, such as the file of the title of media file, size, URL and media file
The information such as type.The attribute information includes first kind field, for calling corresponding player plays media file.Its
In, which is the file namely DLNA files applied to DLNA technologies.
Either software bug may result in certain field errors in attribute information or lose for careless omission when software development
It loses, when playback equipment is when receiving the media file, can confirm the first kind field that media file carries：upnp:clas
It is whether legal, if legal, call corresponding player；If illegal, player is called to fail.Here legal refers to matchmaker
Body file carries the value of first kind field, and the normal value that the value of the first kind field is professional standard.
If first kind field is legal, playback equipment calls player plays media text corresponding with first kind field
Part.That is, if playback equipment, which determines, carries first kind field upnp in media file:The value of clas, just to the first kind
Type-word section is parsed, such as upnp:The value of clas fields is：Object.item.videoItem indicates control point push
It is video file, playback equipment is then called plays the video file for playing the video player of video；Or upnp:Clas words
Section value be：Object.item.imageItem, indicate control point push is picture file, and playback equipment is then used for
The picture players of playing pictures play the picture file；Or upnp:The value of clas fields is：
Object.item.audioItem, indicate controller push is audio file, and playback equipment is then called for playing audio
The audio player plays audio file.
202, when player malloc failure malloc, the keyword in Second Type field is obtained, and according to keyword and preset
Keyword database updates first kind field, wherein keyword is the field for the file format for characterizing media file.
May not have in media file caused by due to software developer's horizontal problem or software bug or other
Carry upnp:The value or upnp of clas fields:The value of clas fields is lack of standardization so that when player malloc failure malloc, playback equipment
The keyword in Second Type field can be obtained, and more according to field corresponding with the keyword in preset keyword database
New first kind field namely the keyword database include keyword and first kind field in Second Type field
Correspondence.Wherein, the keyword in Second Type field is the field for the file format for characterizing media file.Such as here
Second Type field is Digital Life Network Alliance DLNA parameters：Protocol Info, protocol Info fields include matchmaker
The detailed DLNA parameters of body file；Or uniform resource locator (the Uniform that Second Type field is media file
Resource Locator, URL).
Specifically, Second Type field be protocol Info when comprising DLNA parameters can be such as the following table 1 institute
Show.
Table 1
| http-get/rtsp-get | * | MIME-TYPE | DLNA.ORG_PN |
Wherein, http-get/rtsp-get indicates the transmission mode of media file between playback equipment and DLNA server,
Http-get is the transmission mode of professional standard, and rtsp-get is optional transmission mode；MIME-TYPE indicates media file
Media formats, such as can be video/mp4, image/jpeg etc.；DLNA.ORG_PN indicates that media file is corresponding specific
DLNA parameters, such as DLNA.ORG_PN can be MPEG4_P2_MP4_SP_AAC, or JPEG_SM etc..It is therein
MIME-TYPE fields and DLNA.ORG_PN fields can characterize the file format of media file.
Alternatively, Second Type field is URL, such as can be：
http://192.168.2.101:58421/cd/getcontent/0/7/9_1.jpg。
During specific implementation, the keyword in above-mentioned acquisition Second Type field, and according to keyword and default key
Numerical data base updates the first kind field：Determine whether Second Type field includes keyword, if including,
Determine the keyword that whether there is Second Type field in preset keyword database, and if it exists, then according to preset keyword number
According to field corresponding with the keyword in Second Type field in library, the first kind field is updated.
If Second Type field is protocol Info, in the first mode in the cards, can be closed by default
First kind field and the correspondence of Second Type field in key numerical data base (libraries key) determine first kind field,
And the first kind field in step 201 is updated, or before updating first kind field, first determine protocol Info
Whether field includes keyword, if including, it is determined that with the presence or absence of protocol Info fields in preset keyword database
Keyword, and if it exists, field corresponding with the keyword of protocol Info fields is then determined as first kind field, this
Be since although media file includes the value of protocol Info fields, may software bug or it is other due to
Lead to the value of protocol Info fields and lack of standardization, if the value specification of protocol Info fields, it is determined that default to close
There is field corresponding with the keyword of protocol Info fields in key numerical data base.
If Second Type field is protocol Info, in second of mode in the cards, in protocol
In the case that Info fields include keyword, the key of protocol Info fields in preset keyword database can be passed through
The correspondence of word and file type determines the key that whether there is protocol Info fields in preset keyword database
Word, and if it exists, file type corresponding with the keyword of protocolInfo fields is then determined as to the files classes of media file
Type, and there is also the correspondences of file type and first kind field in preset keyword database, then can determine indirectly
Go out first kind field corresponding with the keyword of protocol Info fields.
Specifically, with reference to table 1, since protocolInfo fields include MIME-TYPE fields and DLNA.ORG_PN words
Section, MIME-TYPE fields can indicate the file format of media file, and it is specific that DLNA.ORG_PN fields carry media file
DLNA parameters, the file format of media file can also be included, therefore, MIME-TYPE fields or DLNA.ORG_ can be passed through
PN fields infer the first kind field in media file properties information.Therefore, according to the first above-mentioned mode in the cards,
If above-mentioned Second Type field is protocolInfo, it whether there is Second Type word in the determining preset keyword database
Section keyword may include：It determines in preset keyword database and whether there is and the MIME-TYPE fields in DLNA parameters
Or the identical field of DLNA.ORG_PN fields；In the database according to preset keyword with the matchmaker is characterized in DLNA parameters
The corresponding field of field of the file format of body file updates the first kind field and may include：According to the default key
Field corresponding with the MIME-TYPE fields or the DLNA.ORG_PN fields, updates the first kind in numerical data base
Field.
It illustratively, can be according to first kind field and MIME- such as when MIME-TYPE fields are video/mp4
The correspondence of TYPE field determines that field corresponding with video/mp4 fields is：Object.item.videoItem, i.e., with
The corresponding first kind field of keyword of Second Type field is：object.item.videoItem；Alternatively, working as
It, can be true according to first kind field and the correspondence of DLNA.ORG_PN fields when DLNA.ORG_PN fields are JPEG_SM
Determining field corresponding with JPEG_SM fields is：Object.item.imageItem, the i.e. keyword pair with Second Type field
The first kind field answered is：object.item.imageItem.
According to above-mentioned second mode in the cards, playback equipment determines that preset keyword database includes above-mentioned energy
When enough characterizing the field, the i.e. keyword of Second Type field of file format of media file, then according to preset keyword data
The correspondence of the keyword of Second Type field and file type in library, determine in preset keyword database with the presence or absence of with
MIME-TYPE fields in Second Type field or the identical field of DLNA.ORG_PN fields, and if it exists, then determine default close
There is file type corresponding with MIME-TYPE fields or DLNA.ORG_PN fields in key numerical data base, Second Type field
The corresponding file type of keyword is corresponding with MIME-TYPE fields or DLNA.ORG_PN fields in preset keyword database
File type can then be determined indirectly and MIME-TYPE further according to the correspondence of file type and first kind field
Field or the corresponding first kind field of DLNA.ORG_PN fields.
It illustratively, can be according to MIME-TYPE fields and file such as when MIME-TYPE fields are video/mp4
The correspondence of type determines that file type corresponding with video/mp4 fields is video file namely Second Type field
The corresponding file type of keyword is video file, since first kind field and file type are there is also correspondence,
It can determine that first kind field is according to the correspondence of this file type of video file and first kind field：
object.item.videoItem；Alternatively, when DLNA.ORG_PN fields are JPEG_SM, it can be according to JPEG fields and text
The correspondence of part type determines that file type corresponding with JPEG fields is the key of picture file namely Second Type field
The corresponding file type of word is picture file, therefore can be according to pair of picture file this file type and first kind field
It should be related to that determining first kind field is object.item.imageItem；Again for example when DLNA.ORG_PN fields are MPEG4_
When P2_MP4_SP_AAC, files classes corresponding with MP4 fields can be determined according to the correspondence of MP4 fields and file type
Type be video file namely Second Type field the corresponding file type of keyword be video file, therefore can according to regarding
The correspondence of this file type of frequency file and first kind field determines that first kind field is：
object.item.videoItem。
It, can be according to the keyword in URL i.e. for characterizing media if Second Type field is the URL of media file
The field of the file format of file updates first kind field with the correspondence of first kind field.Alternatively, first determining in URL
With the presence or absence of the field of the file format for characterizing media file, and if it exists, determine again in preset keyword database whether
There are in URL for characterize media file file format field, and if it exists, then according in preset keyword database with
The corresponding field update first kind field of field of file format in URL for characterizing media file.
Illustratively, if the URL of media file is：
http://192.168.2.101:For characterizing matchmaker in 58421/cd/getcontent/0/7/9_1.jpg, URL
The field of the file format of body file is jpg, also includes jpg fields in database, and jpg fields with
Object.item.imageItem is corresponded to, then first kind field is updated to object.item.imageItem.
203, playback equipment calls corresponding player according to updated first kind field, and plays media file.
It is illegal in first kind field in this way so that player malloc failure malloc, to need to push away according to Second Type field
, can be after according to Second Type field and the preset keyword database update first kind field when disconnected first kind field, root
Corresponding player plays media file is called according to the first kind field in media file after update.Such as media text after update
First kind field in part is object.item.videoItem, then video player is called to play media file.
The embodiment of the present invention provides a kind of playback method of media file, receives media file, and media file includes first
Type field and Second Type field, and corresponding player is called according to first kind field, when player malloc failure malloc,
The keyword in Second Type field is obtained, and according to keyword and preset keyword database update first kind field,
In, keyword is the field for the file format for characterizing media file, is broadcast accordingly according to updated first kind field calling
Device is put, and plays media file, in this way, when player malloc failure malloc, it can be according to media file in preset keyword database
The field of the file format that can characterize media file of middle carrying with the correspondence of first kind field is counter releases the first kind
Type-word section, and then corresponding player plays media file is called according to first kind field, compared with the prior art in media
File refusal if calling player failure according to first kind field plays media file, and the application can solve media text
Part is likely to occur playback equipment in push can be compatible with the media file, but refuse to play due to that cannot call player
The problem of.
Since the format of URL is complex, the format of the URL of generation is varied, lacks fixed URL specifications or other
Reason, it is understood that there may be the first kind field for calling player cannot be inferred according to URL, such as not including in URL can
Characterize the field of the file format of media file so that there is no identical with the field in URL in preset keyword database
The probability of field is relatively large, and therefore, the accuracy for the first kind field determined according to DLNA parameters is more true than according to URL
The accuracy for the first kind field made is high.It is preferred, therefore, that whether above-mentioned determining Second Type field can including keyword
Think：It first determines in DLNA parameters and preset keyword database with the presence or absence of the word of the file format for characterizing media file
Section, this is because the reasons such as software developer's horizontal problem or software bug are also possible to cause in DLNA parameters for characterizing
If the field of the file format of media file loses either DLNA parameters so lack of standardization
In lack of standardization lead to that second class is not present in preset keyword database for the field of the file format that characterizes media file
The keyword of type-word section then determines whether to include keyword further according to URL, therefore, as shown in figure 3, further embodiment of this invention
A kind of playback method of media file is provided, including：
301, playback equipment receives media file, and determines whether the first kind field of media file is legal, the first kind
Type-word section is for calling corresponding player plays media file to play media file if legal；If illegal, execute
Step 302.
302, playback equipment determines in DLNA parameters whether include the field for the file format for characterizing media file, if wrapping
It includes, thens follow the steps 303；If not including, 305 are thened follow the steps.
303, playback equipment determines in preset keyword database with the presence or absence of the text for characterizing media file in DLNA parameters
The field of part format, and if it exists, then follow the steps 304, if being not present, then follow the steps 305.
304, playback equipment is according to the file format with characterization media file in DLNA parameters in preset keyword database
The corresponding field of field update first kind field, then execute step 308.
305, playback equipment determine in the URL of media file whether include characterization media file file format field,
If including thening follow the steps 306, if not including, thening follow the steps 309.
Since media file can also carry the uniform resource locator of the media file in push in its media file
The field for the file format for indicating media file may be carried in URL, the URL, therefore, when DLNA parameters do not include characterization
The field of the file format of media file, or the field contents of the file format due to characterizing media file in DLNA parameters are not advised
Model is (illegal) so that there is no when the field of the file format of characterization media file, can also lead in DLNA parameters in database
The URL for crossing media file is inferred to the content of first kind field.In this way, can look for whether exist from preset database
Identical with the field in the URL of media file field determines first kind field.
306, playback equipment determines in preset keyword database with the presence or absence of the file format for characterizing media file in URL
Field, and if it exists, then follow the steps 307, if being not present, then follow the steps 309.
Here the field that the file format for characterizing media file in URL is not present in database can be due to generating
URL format it is varied, it is understood that there may be do not conform to the field of specification so that in database there is no in URL for characterizing matchmaker
The field of the file format of body file.
307, playback equipment is according to the field with the file format for characterizing media file in URL in preset keyword database
Corresponding field updates first kind field.
For example, the URL of media file is：
http://192.168.2.101:58421/cd/getcontent/0/7/9_1.jpg, according to it is above-mentioned the first can
The mode that can be realized, preserves pair of jpg fields and object.item.imageItem fields in preset keyword database
It should be related to, accordingly, it can be determined that there is field jpg identical with the field in the URL of media file in preset keyword database,
The corresponding fields of the jpg are object.item.imageItem, it is determined that field corresponding with jpg
Object.item.imageItem is first kind field, in order to which playback equipment can be according in updated media file
First kind field call the picture player plays picture files.
According to above-mentioned second mode in the cards, jpg fields and file are preserved in preset keyword database
Type be picture file correspondence, accordingly, it can be determined that in preset keyword database exist in the URL of media file
The identical field jpg of field, the corresponding file type of jpg fields be picture file, this file type of picture file again with
First kind field is that there are correspondences by object.item.imageItem, therefore, according to the corresponding files classes of jpg fields
Type can determine that first kind field is object.item.imageItem, in order to which playback equipment is according to updated media
First kind field in file calls the picture player plays picture file.
308, playback equipment calls corresponding player according to updated first kind field, and plays media file.
309, playback equipment refusal plays media file, and display reminding information is to remind user.
If there is no there is no literary with media in the field of the file format for characterizing media file or database by URL
The identical field of field in the URL of part, playback equipment can not be inferred to first kind field, also can not just call and broadcast accordingly
It puts device and plays media file, playback equipment is just refused to play the media file, can be shown in the display of playback equipment side
Prompting message is to remind user that the media file can not play, naturally it is also possible to notify the control point media by DLNA server
File can not play.
Therefore, the embodiment of the present invention can also be attempted when the first kind field of media file calls player failure
Infer first kind field by the field of the file format for characterizing media file in the DLNA parameters in media file
Content simultaneously updates first kind field, if the field of the file format in DLNA parameters for characterizing media file is also illegal
When, the content that first kind field is inferred by the field of the file format for characterizing media file in URL can also be attempted
And first kind field is updated, to call corresponding player plays according to the first kind field in media file after update
Media file, if media file does not carry first kind field or the parsing of first kind field in compared with the prior art
Just refusal plays media file for failure, and the application can solve media file and be likely to occur playback equipment in push and can be compatible with
The media file, but the problem of refuse to play due to the failure of first kind field illegal calling player.
