Description
Technical field
The present invention relates to communication terminal browser field, particularly a kind of MP4 stream media play system and application process thereof that is used for communication terminal.
Background technology
Along with the continuous development of the Internet, online Media is used the emphasis that becomes the broadband application development gradually, wherein becomes producer and personal user's focus especially with the stream media technology of MP4 compression standard.
The MP4 form can also be based on H.264 encoding except can encoding based on MPEG-2 AAC.
Adopting the size of the file of MPEG-2 AAC encoding process only is about 3/4ths of * .mp3, but tonequality is better.Built-in waveform/frequency division dynamic audio frequency shows and music manager can be supported multiple coloured image; And H.264 coding more provides higher compression ratio: under equal picture quality condition, data compression specific energy H.264 is higher 2 ~ 3 times than the MPEG-2 that uses in the current dvd system, and is higher 1.5 ~ 2 times than MP4.
The MP4 form is a outstanding stream media format, is widely used in various online Media field at present.
One of MP4 file All Files existence is called in the container of movie, and two header file fritter contents simply are housed in the movie container:
1) header file of MP4 file (index);
2) data file of MP4 file (data).
Data file data is pure media article data, but these data can not directly be played software identification and play, header file index does not contain media data, but it has indicated each frame, the size of each aggregate of data, in the position of data and use what mode to decode.
The special format of MP4 has caused following defective:
Traditional broadcast mode is the header file that playout software has been resolved earlier the MP4 correspondence, just begins to play after the overall architecture of acquisition media file.
If the file volume is bigger, the corresponding file header will be very big also so, insert under the environment (such as playing on mobile communication terminal) at low network speed, and the MP4 file that online broadcast is such needs very long wait (file header loads and the waits for) time.
For time span is 1 hour MP4 file, and its header file is just near 1MB, for the hardware handles ability of mobile communication terminal, once finishes and resolves this header file and need the long time.If carry out online broadcast,, the download load time that needs are very long,, be enough to allow the user abandon watching adding that header file resolves the needed time with present arrowband wireless access (20K/s).
Summary of the invention
The invention provides a kind of stream media play system that is used for mobile communication terminal, solving in the prior art since etc. the file header of large volume files in stream media to be loaded, cause long technical problem of load time.
Another object of the present invention is to provide the application process of this stream media play system.
In order to realize first purpose of the present invention, adopt following technical scheme:
The invention provides a kind of MP4 stream media play system that is used for mobile communication terminal, comprise being arranged on the header file acquisition module that mobile communication terminal is used for obtaining from the Internet MP4 Streaming Media header file, obtain the data acquisition module of MP4 stream medium data file and the playing module of playing corresponding data file according to the information of header file from the Internet.
System also comprises: MP4 Streaming Media header file is resolved into the decomposing module of a plurality of header file fritters, and decomposing module is connected with the header file acquisition module.
Decomposing module is divided into several header file fritters according to mobile communication terminal performance and the Internet capability with file header.As long as has resolved the little build of header file just can directly download the correspondence data file portion play corresponding media file.
As a kind of preferred version, decomposing module is arranged on mobile communication terminal, is the submodule of header file acquisition module.Decomposing module resolves into a plurality of header file fritter subfiles with the Streaming Media header file on the Internet and downloads to mobile communication terminal as the submodule of header file acquisition module.
As another preferred version, decomposing module is arranged on transfer server, with the header file acquisition module by Internet connection.Decomposing module is arranged on transfer server then can obtain header file earlier at server, resolve into a plurality of header file fritters by decomposing module then after, send to the header file acquisition module of mobile communication terminal respectively.
As preferred version further, decomposing module resolves into header file the header file fritter of fixed size.
As further preferred version again, decomposing module resolves into the header file fritter that fixed size is 100K to header file.
Another preferred version of the present invention, system also comprises the adjusting module that is used to detect and adjust the header file position that is arranged on transfer server, adjusting module and header file acquisition module are by Internet connection.
The header file of general MP4 formatted file is before data file, but header file is also arranged data file after, for a kind of state in back, adopts the general processing mode (resolving from top to bottom in order) can the more time of consumption.The processing mode of adjusting module is: the header file that will be positioned at the bottom is mentioned the front, or begins to resolve from the bottom.
The preservation form of header file and data file is different, borrows this point, and the position that just can judge the medium header file is front or back.
In order to realize second purpose of the present invention, adopt following technical scheme:
The invention provides a kind of application process that is used for the MP4 stream media play system of mobile communication terminal, comprise the steps:
(71) obtain the header file obtaining step of MP4 Streaming Media header file from the Internet by the header file acquisition module;
(72) obtain the data acquisition step of MP4 stream medium data file from the Internet by data acquisition module;
(73) play the broadcast step of corresponding data file according to the information of header file;
Above-mentioned header file obtaining step resolves into a plurality of header file fritter subfiles by decomposing module with the MP4 Streaming Media header file on the Internet and downloads to mobile communication terminal.
As a kind of preferred version, concrete operations are as follows:
(81) by decomposing module header file is resolved into a plurality of header file fritters;
(82) pass through the header file fritter that the header file acquisition module is downloaded header file;
(83) after a header file fritter is finished in download, obtain MP4 stream medium data file and the counterpart header file fritter from the Internet and play by data acquisition module;
(84) repeated execution of steps (82)-(83) finish or the user stops to play up to files in stream media.
As another preferred version, application process also comprises the set-up procedure that detects and adjust the header file position by adjusting module on transfer server.
As preferred version further, the concrete operations of set-up procedure are as follows:
(101) position of detection head file and data file relation;
(102) if header file after data file, is then downloaded header file earlier, otherwise direct execution in step (103);
(103) the delivery header file is to mobile communication terminal.
The present invention is by downloading the segmentation of MP4 Streaming Media header file, reduces the user and waits for downloads time of whole header file, allows the user browse the MP4 Streaming Media as early as possible.
Invention has overcome the defective of files in stream media itself, has reduced the media play stand-by period, makes it to be fit to more online propagation, particularly under the arrowband internet environment.
