Description
Technical field
The invention belongs to network information processing technical field more particularly to a kind of digital video compression processing method and
System.
Background technique
Currently, the prior art commonly used in the trade is such that
Video code conversion market has begun the concern for having attracted many digital equipment manufacturers and semiconductor company.The former for
Market actual demand is considered, and generally all self-developing to ASIC transcoding chip H.264 and is integrated in product from MPEG-2 out
In.Such as the HDD video recorder DIGA series of Panasonic use oneself exploitation UniPhier chip, can record program when
The H.264 format that 17Mbps is converted into 5.7Mbps based on the digital television signal of MPEG-2 is waited, so that video greatly improved
Recording time.The companies such as the Sony and Hitachi of Japan were also proposed the production with transcoding function using own chip in 2007
Product.
As semiconductor company promotes the interest of transcoding technology, support MPEG-2, H.264, the multiple formats such as VC-1 turn
The new product changed also appeared on the market in last year successively.But strategy is also not exactly the same, the realization rate of transcoding technology has deviation soft at present
Part and two kinds of hardware, the former generally use high-speed computer perhaps high performance DSP the latter generally use dedicated ASIC or
FPGA.The difference of these types of scheme is spoken of, TI general dsp is thought: " the application middle and high end DSP of digital video decoding and transcoding
It is main force's platform always in real-time processing.In basic media-processing platform, ASIC class chip is completed to deliver once designing
Flow, then various functions cannot change again；Though FPGA category has hardware programmable device, but if hardware design is completed and making sheet
Later, it is difficult to the change for having big again；DSP is concerned place as embedded software programmable platform and is to support comprehensively
Various video standard algorithms, product is even completed can still be upgraded by the method for software upgrading."
TI supports that the high-definition multimedia processor DM6467 of multi-format is the SoC comprising multiple processors and core,
It is not enumerating for multiple parallel processing elements.Primary video processing core is high speed high definition coprocessor (HD- in DM6467
VICP), three portions of high-speed dsp and video data transform engine.Wherein HD-VICP passes through the coding and decoding dedicated accelerator of two panels
The DSP processing capacity for being equivalent to 3GHz or more is realized, supports HD 1080i H.264 high class transcoding；High-speed dsp uses dominant frequency
For the C64+ core of 600MHz, when auxiliary supports H.264 high definition encoding and decoding and transcoding, spent clock is lower than 300MHz, and DSP is answered
With very flexibly, early stage algorithm had both been supported, also support new algorithm and proprietary algorithm.Video data transform engine has under video
Vertical adjusting device can reduce DSP load, and chroma samples are completed within hardware, and have menu covering function.DM6467 is also integrated with
The ARM9 core of 300MHz, can support a variety of embedded real-time operating systems, and realize various master controls and management work.
The market demand
The development of Video Transcoding Technology and ever-increasing demand and broadcasting digitalization process are closely related, turn at present
The main application fields of code technology are digital television broadcasting and Digital Media front-end processing." in fact, the application of more decoding chips
It is to be applied on ' seeing ' program, it allows equipment that can support a plurality of types of signal sources." Fujitsu's market manager's Huang relies on oneself finger
Out: " but some occasions only need a kind of signal source, such as the front end of cable television sometimes, broadcast and save preferably with same format
Mesh, at this time with regard to needing to convert the format of a part of program."
Current a large amount of digital video programs are MPEG-2 format, and many new playback equipments are to improve transimission and storage effect
Rate and use the MPEG-4 H.264 advanced digitals code/decode format such as Real VC-1 AVS, therefore turn derived from MPEG-2
Code technology largely uses, and the requirement to fine definition transcoding related to this is also higher and higher, especially real-time transcoding skill
The raising of art and its realization rate.
In addition, in MPEG-2 format, occupancy hard drive space is too many, and a high-definition movie will account in hard disk video recorder
The hard drive space of 8G or so, this just needs to change into the H.264 format of more high compression ratio, to expand capacity, saves the throwing of hard disk
Enter cost, while the weight and volume of complete machine can also be reduced.As the MB86H52 of Fujitsu can guarantee program quality not
In the case where change, up to 5 times of capacity extension.
Also under some occasions, for example program being transmitted using network, MPEG-2 just needs to occupy biggish bandwidth, if
Bandwidth is limited, so that it may the signal of MPEG-2 be changed into signal H.264, transmitted with lesser bandwidth, and may be used also
Further to utilize video code conversion processor to reduce the code rate of H.264 signal, enable the transmission for adapting to network.
Transcoding technology will be used to meet the digital video multi-standard conversion requirements of wide range of areas, be not only applicable to include view
In the commercial products such as frequency broadcast transcoding, media network management, more conference devices, medical imaging and video monitoring, and it will be used to wrap
Include DMA, HD video conference terminal, advanced digital set-top box, IP visual telephone and high-definition network camera etc.
Consumer product.It is very necessary in commercial product transit code technical support more high density, and in consumer product transit code technology
Monolithic high performance-price ratio it is then required.
Huang, which is relied on oneself, to be also indicated that: " application market of transcoding device is still very big, and new application will be also increasingly developed out
Come."
With content is king, the video content that can convert arbitrary format in real time is future market hair in current video entertainment market
One core trend of exhibition.Even if not understood by everybody, but Video Transcoding Technology will be widely used.Video turns
Code, which refers to the process of, is converted to another video format for a certain video format, is usually all first temporarily to decode video, then weighs
Newly encoded format and data coding rate at needs.
IDC analysis indicates three kinds of main transcoding demands: the conversion between different video format, for example, from MPEG-2 or
H.264 MPEG-4 is gone to；Content transmission changes bit rate and meets the needs of heterogeneous networks bandwidth or device plays speed；Clearly
HD video is switched to the even lower clarity of SD, the latter's reverse process by clear degree.Typical example is, in order to be compiled
Volume and the application by uploaded information to website (such as YouTube) and by video from camera transmissions to PC.Video data transmission
When, code conversion is also carrying out；Such as from video camera (AVI format) to the PC (MPEG-2 for editor；For storage
MPEG-4 website (H.263/H.264/Flash/ etc.)) is arrived again.If to watch the file on website on PC, need to hold again
Line code conversion can play on RealPlayer or Windows Media Player.
Compression of digital video has become a kind of almost all very important technology in various types of Video Applications.With
The trend of Media Convergence continues to develop, and compression and Interoperability will become more and more important.DVD, HDTV, visual telephone/electricity
Letter meeting and the video monitoring system occurred recently are foremost several digital video applications.
But, the historical background that the system-level technology of these products is had nothing in common with each other, therefore, it is necessary to using different compression calculations
Method.Preferred number in digital video market increases substantially, and especially introduces H.264 (MPEG-4 Part 10) in the market
After the novel codecs such as AVC (advanced video coding) and WMV9.Meanwhile the engineers for being responsible for video system design still have to
With only support several old plants (as H.261, H.263, MPEG-2 or MPEG-4 part 2) traditional equipment come into contacts with.
But in some applications, which must have and be integrated with the energy that the novel device of latest algorithm interoperates
Power.The exploitation of algorithm is also the problem for being imbued with challenge.When new algorithm with better function is developed and by standard
After change, it is necessary to guarantee that they are compatible with original algorithm, this is being bound to arouse fear for a task, it is, therefore, necessary to develop one
A little powerful general transcoding (transcoding) schemes.
The problem of in terms of intellectual property, is even more complicated.Although many video coding algorithms (such as MPEG-2, MPEG-4,
It H.263 and H.264) is disclosed standard, but some other algorithm (such as On2 and Real Video) is proprietary.Proprietary calculation
Method can also become canonical algorithm sometimes.For example, originally finally becoming due to being adopted by SMPTE association for the WMV9 of proprietary algorithm
Public VC1 standard.
In conclusion problem of the existing technology is:
(1) it can not accomplish visual parameter setting, because the parameter setting of ffmpeg video processing at present is all direct
It is arranged in code；
(2) it can not dynamically be arranged or modify parameter, complete execute of current parameter setting is gone in a manner of order line
