Description
Technical field
The present invention relates to field of broadcast televisions, synthesis is rendered more specifically to video and audio file and subtitle file
Method and system.
Background technology
With developing rapidly for information technology, broadcasting media channel and audient are also more and more extensively and diversified, used as matchmaker
The core force that body is propagated, TV station will also consider channel and the audient to be propagated in program production process.Such as, equally
News program when TV station different channel is broadcasted or when being broadcasted towards different audients, it is necessary to show different captions or
Different languages of identical caption content etc., such as captions are identical but be different local languages.Production before program broadcast
Make with during storage management, such as storage of program material, lookup is remake, send and broadcast production link with preview, program
In, often it is accomplished by carrying out respective handling to different captions different languages.Therefore, TV station is same in the making of program regards
Frequency picture often just has multiple difference captions, or needs to change different captions in video replay.Consequently, it is possible to such as
What efficiently manages these video files and subtitle file, is exactly that TV station needs to face while being also in multimedia asset management
Need the problem for solving.
At present in the TV station of radio, TV and film industries, all by media asset management system to files such as media audio/video programs
It is managed.But all it is often unification management, such as video and audio file and word when management multi-version captions and video
Curtain file binding, directly will carry out packing transcoding, after so synthesizing when program making in subtitle superposition to video pictures
File when be saved in media asset management system with regard to only one of which program file, subtitle file be not it is independent, this
It is unfavorable for subsequently editing again.Simultaneously as media resource system subsequently needs the retrieval for providing video and audio for user to browse etc. function,
In view of reducing volume of transmitted data and reducing bandwidth, the video and audio of high standard definition code check file high is being saved in the same of media resource system
When need to carry out the conversion of low bit- rate, and the low bit- rate after thus changing is also video pictures be directly synthesized with captions together with
File.
Fig. 3 is the caption managed process schematic of video/audio of prior art.As shown in figure 3, working as to enter in media resource system
When row lookup is browsed, the low bit-rate video file of overlapping text can only be browsed.Also, because subtitle file has been synthesized to
On video, can only by CPU calculate carry out video decoding and picture render, it is impossible to make full use of the computing resources such as GPU.When this
When program there are multiple subtitle files, the selection of subtitle file cannot be also carried out, subtitle file can only be changed from Program Making System
Synthesis is remake, then by the conversion of low bit- rate again, media resource system is saved in.
But one of function of media resource system is exactly in order to business department carries out lookup recycling to the video and audio material for preserving.
When media resource system wishes that reusing the program is remake or broadcasted again, then video pictures have been folded in itself
Captions are added, producer cannot obtain the pure original video pictures without captions.This namely we often in TV
On see some programs lower section the fuzzy regions such as mosaic occur, then in this fuzzy region again covered it again
The reason for his captions.
Certainly, TV station's service management department also uses the mode that video material with captions separate, i.e. program making and closes
Into when a synthetic video and audio file, and subtitle file is not also changed when changing low bit- rate, so, be saved in matchmaker's money
Just there are high standard definition video and audio file, subtitle file and low bit- rate file when system respectively.But work as is carried out in media resource system
The lookup of program and when browse, it is impossible to browsed simultaneously to subtitle file, subtitle file can only be used as independent annex
Storage, it is impossible to provide effective reference information to user, and video pictures when browsing equally be by CPU carry out decoding and
Render, cannot equally make full use of GPU computing resources.
The above, is prior art problem encountered.If carrying out a program to each subtitle file
Making synthesis and low bit- rate conversion, then be undoubtedly reduction to production efficiency and the efficiency of management, while improving production process
In recruitment cost.In addition, cannot also retain original video pictures, to later video and audio material, Commercial cultivation leaves again
It is sorry.If being saved in media resource system by the way of material picture is separated with captions, again cannot to user provide in real time,
Intuitively captions reference information, user can only check caption content by way of third party software opens subtitle file, but
So again it cannot be guaranteed that the demand of caption information and video and audio picture synchronization, also brings to user and use inconvenience and puzzlement.
The content of the invention
The present invention is regarding to the issue above, it is proposed that one kind renders synthetic method and system, the present invention make full use of CPU with
