Abstract
The invention relates to a transcoding technology, in particular to a distributed media format transcoding method. Aiming at the defects of the prior art, the invention proposes the distributed media format transcoding method which can carry out the real-time transcoding of media content. The key points of the technical proposal can be summarized as follows: a. a media source device carries out the sub-chip processing on a media source; b. the media source device carries out selective distribution on sub-chips; c. a media source transcoding device carries out the transcoding operation on the sub-chips according to a target format which is designated by the media source device; d. the media source transcoding device returns the sub-chips after the completion of the transcoding to the media source device after the completion of the sub-chip transcoding and simultaneously returns the serial numbers of the sub-chips; and e. the media source device carries out the sequencing and the merging of the sub-chips after receiving the sub-chips after the transcoding according to the serial numbers of the sub-chips so that a complete media source after the transcoding is formed by connection. The distributed media format transcoding method has the advantages that the distributed media format transcoding method can realize the real-time transcoding function and save the transcoding time.
Description
Technical field
The present invention relates to transcoding technology, relate in particular to a kind of distributed media format code transferring method.
Background technology
Along with computer technology and development of internet technology, content of multimedia on the network also becomes increasingly abundant, simultaneously emerged in large numbers the encapsulation format of multiple media coding form and multiple medium in this in order to adapt to different demands, the media coding form is such as Mpeg1, Mpeg2, Mpeg4, H264, AVS or the like, the medium encapsulation format is such as asf, wmv, avi, mkv or the like, so many media coding form and medium encapsulation format will realize that for media decoder whole compatibilities are the headachy things of part, especially those multimedia terminal equipments of decoding by hardware, the media formats that they are supported is extremely limited, therefore in order to solve this format compatible contradiction, people generally adopt the media format code transferring technology.The media format code transferring technology is exactly that coded format with medium is transformed into another coded format by a kind of coded format, perhaps is transformed into another medium encapsulation format by a kind of medium encapsulation format, and perhaps the two all transforms.Because the media transcoding technology relates to the decoding of media formats and the recompile of media formats, thereby amount of calculation is very huge, need take a large amount of system resource, therefore on unit, be difficult to realize real-time transcoding function, need take a large amount of time.Prior art does not also have a kind of distributed media format code transferring method.
Summary of the invention
Technical problem to be solved by this invention is: at the deficiencies in the prior art, propose a kind of DMF code-transferring method that can carry out real-time transcoding to media content.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of DMF code-transferring method may further comprise the steps:
A. the coded format in medium source equipment analyzing medium source and encapsulation format carry out burst to source of media and handle, and each burst is assigned with a sequence number, is used for identifying the position of this burst in source of media;
B. medium source equipment carries out selectivity distribution burst according to the transcoding ability of each source of media transcoding equipment, informs the object format of the source of media transcoding equipment transcoding that obtains burst simultaneously;
C. source of media transcoding equipment carries out the transcoding operation according to the object format of medium source equipment appointment to burst;
D. after source of media transcoding equipment was finished the burst transcoding, the burst that transcoding is finished returned to medium source equipment, passes the burst sequence number simultaneously back;
E. behind the burst of medium source equipment after receiving transcoding, it is sorted and merge, connect into the complete source of media behind the transcoding according to its sequence number.
The invention has the beneficial effects as follows: can realize the real-time transcoding function, save the transcoding time with respect to prior art.
Description of drawings
Fig. 1 is a method flow diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
At the deficiencies in the prior art, the present invention proposes a kind of DMF code-transferring method that can carry out real-time transcoding to media content, by source of media is carried out the burst transcoding, improves the transcoding speed of whole source of media.
As shown in Figure 1, distributed media format code transferring method among the present invention is realized by following steps: (1) source of media burst, this stage is finished by medium source equipment, in this stage, medium source equipment carries out burst to source of media, by this Fragmentation by the coded format and the encapsulation format in analyzing medium source, original source of media is divided into a plurality of little bursts, and this kind burst is preserved the encapsulation format and the coded format of original source of media content.After source of media is carried out burst, make a source of media to be carried out the transcoding operation by a plurality of source of media transcoding equipment simultaneously.Source of media each burst behind burst will be assigned to a sequence number, and this sequence number is used for identifying the position of this burst in source of media.
(2) burst distribution, after medium source equipment carries out Fragmentation to source of media, medium source equipment will be selected according to the ability of source of media transcoding equipment, and selection can be finished the source of media transcoding equipment of this transcoding task, and burst will be distributed on the source of media transcoding equipment of selection.In the distribution burst, the object format of medium source equipment notice source of media transcoding equipment transcoding.
(3) burst transcoding, source of media transcoding equipment carry out the transcoding operation according to the object format of medium source equipment appointment to burst after receiving corresponding burst.
(4) burst passback, after source of media transcoding equipment is finished the operation of the transcoding of burst, source of media transcoding equipment need return to medium source equipment by the burst that transcoding is intact, in passback, the burst sequence number of former burst will together be returned to medium source equipment, for medium source equipment reduction media content.
(5) burst connects, and behind the burst of medium source equipment after receiving transcoding, it is sorted and merges according to the sequence number of burst, connects into the complete source of media behind the transcoding.
Claims (1)
- [claim 1] a kind of DMF code-transferring method is characterized in that: may further comprise the steps:A. the coded format in medium source equipment analyzing medium source and encapsulation format carry out burst to source of media and handle, and each burst is assigned with a sequence number, is used for identifying the position of this burst in source of media;B. medium source equipment carries out selectivity distribution burst according to the transcoding ability of each source of media transcoding equipment, informs the object format of the source of media transcoding equipment transcoding that obtains burst simultaneously;C. source of media transcoding equipment carries out the transcoding operation according to the object format of medium source equipment appointment to burst;D. after source of media transcoding equipment was finished the burst transcoding, the burst that transcoding is finished returned to medium source equipment, passes the burst sequence number simultaneously back;E. behind the burst of medium source equipment after receiving transcoding, it is sorted and merge, connect into the complete source of media behind the transcoding according to its sequence number.
