Abstract
A method for enabling a household player to gain the function of playing a 3GP media file comprises the following steps: a file is loaded into a file buffer; a 3GP file parsing module removes the file from the file buffer, and detects whether the data format of the file is 3GP format; if the file format is not 3GP format, the file is directly sent to a corresponding decoder; if the file format is 3GP format, the 3GP file is parsed, and coding format information is removed from the file, stored in the buffer, and then transmitted to the decoder; the decoder selects a corresponding decoding unit for decoding according to the data coding format; and audio and video data streams generated after decoding are output for playing. The invention adopts a concise and efficient design scheme for enabling the household player to gain the function of playing the 3GP media file, thereby enabling more people to experience the joy brought to our lives by cell phone media files by various means.
Description
Technical field
The present invention relates to the Play Technique for Multimedia field, relate in particular to the method that a kind of household player is supported the 3GP media file playing function.
Background technology
3GP is the multimedia file format on the 3G mobile that is mainly used in of 3rd Generation Partnership Project (3GPP) tissue proposition, now has been widely used in multimedia file transmission and broadcast on the mobile phone.The multi-medium data of 3GP form adopts and has been widely adopted H.263, the generation of encoding of multimedia coding techniques such as MPEG4.Along with popularizing that 3G mobile is used, the multimedia file of 3GP form will be by wide-scale distribution, and existing household player such as DVD, VCD, Blu-ray DVD, HDDVD, CH-DVD, TV set-top box etc. are not supported the broadcast of the multimedia file of 3GP form.If make the high existing household player of these occupation rates can support the multimedia file of the 3GP form of current trend, it must have good market prospects.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of household player to support the method for 3GP media file playing function, it makes existing normal domestic use player can play the multimedia file of 3GP form, allows more people enjoy the enjoyment that the mobile media file brings to people's life by different approach.
For achieving the above object, the invention provides the method that a kind of household player is supported the 3GP media file playing function, comprise the steps:
(1) file is written into filebuf;
(2) from filebuf, read file by a 3GP document analysis module, judge whether its data format is the 3GP form;
(3), then directly file is delivered to corresponding decoder if file format is not the 3GP form;
(4) if file format is the 3GP form, then resolve the 3GP file, read wherein encoding format information, and data are deposited buffering area, pass to decoder;
(5) decoder selects the corresponding decoding unit to decode according to data encoding format;
(6) the decoding back generates Voice ﹠ Video data flow output broadcast.
Wherein, described household player includes but are not limited to DVD, VCD, Blu-ray DVD, HDDVD, CH-DVD, TV set-top box, can expand to the multiple household player that can not play the 3GP file as 3G mobile and computer.
Wherein, described 3GP document analysis module can resolve H.263 at least, 3GP document No. mode such as MPEG4.
Wherein, described household player is a DVD player.
Wherein, described decoder is supported form multi-medium datas such as MPEG1, MPEG2 are decoded at least.
The present invention increases 3GP document analysis module in the decoding chip of existing household player, after multimedia file deposits the filebuf of household player in by optical data disk or transmission network, this module judges whether data are the 3GP form in the filebuf, if not then directly delivering to corresponding decoding unit, otherwise, resolve the 3GP file, read the various information of wherein encoding, and data are deposited in the buffering area, in coded format according to data, select corresponding decoding unit, the broadcast of decoding.
The present invention is on the basis that keeps original household player system configuration, realized of the support of normal domestic use player with succinct effectively design, thereby can allow more people enjoy the enjoyment that the mobile media file brings to people's life by different approach to the 3GP media file.
Description of drawings
Below in conjunction with accompanying drawing,, will make technical scheme of the present invention and other beneficial effects apparent by the specific embodiment of the present invention is described in detail.
In the accompanying drawing,
Fig. 1 supports the structure and the data flow diagram of the method for 3GP media file playing function for household player of the present invention;
Fig. 2 is the workflow diagram of a preferred embodiment of the method for household player support 3GP media file playing function of the present invention.
Embodiment
Fig. 1 supports the structure and the data flow diagram of the method for 3GP media file playing function for household player of the present invention.As shown in the figure, after the household player system start-up, at first carry out step 1 and carry out file buffering; The present invention increases 3GP document analysis module and carries out step 2 pair 3GP document analysis on the basis of existing household player Play System, this module reads file from filebuf, the coded system of multi-medium data in the identification file, select according to decoder 3 in the coded system control original system then, data are passed to decoder 3; At last, carry out the decoded data that step 4 audio frequency and video broadcast decoder device generates.
Fig. 2 has disclosed the workflow diagram that is applied on the existing DVD player for the workflow diagram of a preferred embodiment of the method for household player support 3GP media file playing function of the present invention, and it is realized on existing DVD decoding chip basis fully.Empty frame has shown the course of work of 3GP document analysis module among the present invention among the figure.As shown in the figure, after DVD player started, step 11 was loaded DVD; Step 12 is carried out file buffering, and the file in the optical data disk is written into filebuf; Next step 13 carries out the 3GP document analysis, from filebuf, read file, utilize 3GP document analysis module to read file format, step 14 judge file format whether for H.263,3GP document No. mode such as MPEG4, if not then directly delivering to corresponding decoding unit; If the 3GP file is then resolved the 3GP file, step 15 reads the various information of wherein encoding, and step 16 is deposited data in the buffering area; At last multi-medium data coding is passed to decoder, step 17 is according to the coded format of data, and step 18 is selected corresponding decoding unit, step 19 broadcast of decoding.The present invention implants 3GP document analysis module in the decoding chip of existing household player, makes it support the 3GP media file playing function.
Equally, the present invention program can according to the similar form of present embodiment, on such as VCD, TV set-top box, DVD, Blu-ray DVD, multiple existing multimedia players such as HD DVD, CH-DVD, implement.
