Abstract
The invention discloses a kind of system and method filtering the media file that display device can not be play, described method includes: 1) preserve the example media file that portion can play；2) resolve media file to be played, obtain media file and resolve information；3) example media file and media file being resolved information to contrast, recording media file virtual value when full terms is all to correspondence is true；4) being that genuine media file I frame data are decoded to virtual value, if successfully decoded, record media file virtual value is true；5) it is in the playlist that genuine media file adds player to by virtual value.The present invention uses filtering module to filter media file, the media file that can play is identified, the media file that can play is added in the playlist of player by user, so that the media file in playlist all can be play, enables users to use swimmingly display device.
Description
Technical field
The present invention relates to filter system and the filter method of the media file that display device can not be play.
Background technology
At present, when people play media file with display device, only after point opens media file, just know that can media file be play.Because playlist if what user's point opened is just the file that can not play, then may waste the time of user containing the file that can not play.Player is only by detection media file suffix name at present, carry out filtering the file that can not play, and some media file is caused by factors such as file coding format in the inner, resolution, durations when can not play, these media files can not be filtered out by existing filter method, still can affect the use of user.
Summary of the invention
It is an object of the invention to provide and a kind of the media file that can not play can be filtered completely, and the easy to operate system filtering the media file that display device can not be play and filter method.
For achieving the above object, the present invention uses following technical scheme: a kind of system filtering the media file that display device can not be play, it includes that display device and mobile memory, mobile memory internal memory contain media file to be played；Document scanner, microprocessor, filtering module, enquiry module, display module and player it is provided with in display device；Wherein,
Document scanner: the media file all to be played in mobile memory is scanned and gathers media file essential information；
Microprocessor: be stored with playable example media file；Being additionally provided with data base in microprocessor, databases contains the media file essential information to be played that document scanner gathers；
Filtering module: it includes document parser and pre-player, document parser contrasts for resolving media file to be played in mobile memory and playable example media file and media file to be played being resolved information；Pre-player is for being decoded media file I frame data to be played；
Enquiry module: for inquiring about the data base in microprocessor, be in the playlist that genuine media file adds player to by virtual value；
Display module: for the media file storage of correspondence document base information in data base in player plays list is shown on the screen of a display device.
Described display device includes liquid crystal display, liquid crystal TV set or mobile phone.
The filter method of the above system filtering the media file that display device can not be play of application, described method includes:
1) being stored in playable example media file in microprocessor, the information that this example media file includes has: file coding format, Document encapsulation type, supported decoder type, optimum resolution scope；
2) media file to be played in mobile memory is resolved by the document parser in filtering module, obtaining media file to be played and resolve information, this media file to be played resolves information and includes: file coding format, Document encapsulation type, supported decoder type, resolution, duration；
3) example media file of storage during filtering module transfers microprocessor, the file coding format in media file parsing information to be played is judged respectively by the document parser in filtering module, Document encapsulation type, supported decoder type whether with the file coding format in example media file, Document encapsulation type, supported decoder type one_to_one corresponding, judge whether the resolution in media file parsing information to be played falls in the range of the optimum resolution of example media file simultaneously, as long as there being a condition the most corresponding, the virtual value then recording media file to be played is false；The virtual value recording media file to be played when full terms is all to correspondence is true；
4) it is that genuine media file to be played is further filtered to virtual value in step 3), whether it is the integer more than zero by the duration during document parser judges the parsing information of above media file excessively, if being greater than the integer of zero, the virtual value then recording media file to be played is true, otherwise, the virtual value recording media file to be played is false；
5) the pre-player read step 4 in filtering module) in virtual value be media file the most to be played, being decoded described media file I frame data, if successfully decoded, it is true for recording media file virtual value to be played, otherwise, record media file virtual value is false；
6) it is true time when the virtual value of step 5), the media file that this is to be played is added in the playlist of player.
Use above filtering media files method, use filtering module that media file to be played is filtered, the virtual value of playable media file is recorded as very, directly being play these virtual values by player is genuine media file, saving user time, user can use display device more smoothly.
In the present invention, using the document parser in filtering module, the information that resolved by media file contrasts with the example media file that can play in microprocessor, thus filters the media file that can not play.
The present invention also uses the pre-player in filtering module to read media file I frame data to be played and is decoded, and filters the media file that can not decode, and then filters the media file that a part can not be play.
Described carry out step 1) operation before, first by document scanner, the media file all to be played in mobile memory is scanned, gather media file essential information to be played, and the media file essential information of collection is stored in the data base of microprocessor.
The virtual value of media file to be played in described step 6) is true time, by the constituent instruments information of the media file that virtual value is true write correspondence in the data base of microprocessor.
Data base in described enquiry module inquiry microprocessor, adds to the media file that virtual value is the most to be played in the playlist of player.
Use above mode, the media file to be played in mobile memory can be filtered and labelling, it is simple to when playing, be directly in the playlist that genuine playable media file adds player to by virtual value.
The media file storage of correspondence document base information in data base in playlist is shown on the screen of a display device by described display module.
I frame (Iframe) is also called Intra pictures (intrapicture), and I frame is typically a kind of video compression technology that each GOP(MPEG is used) first frame, through moderately compressing, as the reference point of random access, image can be treated as.
In the present invention, using filtering module to filter media file to be played, be identified playable media file, playable media file is added in the playlist of player by user again by enquiry module.So, the media file in the playlist of player all can be play, and enables users to use swimmingly display device.The method of the filtering media files of the present invention, according to the filter result of filtering module, prompting user's media files is the most effective so that player more hommization, intellectuality.
