Technical field
The present invention relates to digital medium information treatment technology, especially relate to a kind of Video coding treatment technology.
Background technology
More and more perfect with safety-protection system, photographic head can get more and more, the definition meeting more and more higher of video, and video is compiled
Code technology decides quality and the size of video, and current video coding technique is various, and old coding techniques is not dead, and new technique is
Stable development, progressively knows future, and new used equipment operates in respective safety-security area, and each coding techniques has oneself one
The ground of seat.
So-called Video coding mode just refers to, by specific compress technique, the file of certain video format is converted into separately
A kind of mode of video format file.In video streaming of paramount importance encoding and decoding standard have International Telecommunication Association H.261,
H.263, H.264, the MPEG system of the M-JPEG of motor rest motion picture expert group version and Motion Picture Experts Group of International Organization for Standardization
Row standard, be widely used on the internet in addition also have the RealVideo of Real-Networks, Microsoft WMV with
And the QuickTime of Apple company etc..
As follows than major coded format includes at present.
H.26X series (by ITU [international videotex alliance] dominate) include H.261, H.262, H.263, H.264,
H.265：
(1)H.261：Main use in old video conference and videophone products
(2)H.263：It is used primarily in video conference, visual telephone and Internet video
(3)H.264：H.264/MPEG-4 Part X, or claim AVC (Advanced Video Coding, advanced video
Coding), it is a kind of video compression standard, a kind of recording of high accuracy video being widely used, compression and issue form.
(4)H.265：High efficiency Video coding (High Efficiency Video Coding, abbreviation HEVC) is a kind of
Video compression standard, the H.264/MPEG-4 successor of AVC.HEVC is considered not only to be lifted picture quality, also can reach simultaneously
H.264/MPEG-4 the compression ratio (be equal to bit rate under same image quality and decrease 50%) of AVC twice, can support that 4K divides
Resolution even arrives super hd-tv, and highest resolution can reach 8192 × 4320 (8K resolution), and this is becoming of current development
Gesture.Until 2013, Potplayer with the addition of the decoding for H.265 video, not yet has popular encoding software to occur.
MPEG series (by MPEG [motion picture expert group] exploitation of ISO [mechanism of International Standards Organization] subordinate) video is compiled
Code aspect mainly has：
(1) (MPEG-1 Part II is mainly used on VCD MPEG-1 Part II, and some Online Videos are also using this
Plant form.The quality of this codec is generally suitable with original vhs video band.)
(2) (H.262 MPEG-2 Part II is equal to MPEG-2 Part II, using in DVD, SVCD and most of number
In word video broadcast system and cable distribution systems (cable distribution systems).)
(3) (MPEG-4 Part II standard can use in network transmission, broadcast and media storage MPEG-4 Part II
On.Compared with MPEG-2 and the first edition H.263, its compression performance increases.)
(4) (MPEG-4 Part X is technically and H.264 ITU-T is identical standard, sometimes for MPEG-4 Part X
Time is also designated as " AVC ") finally this two coding Cooperation, be born H.264/AVC standard.ITU-T orders to this standard
Entitled H.264, and ISO/IEC it be called MPEG-4 advanced video coding (Advanced Video Coding, AVC)
Other series：AMV、AVS、Bink、CineForm、Cinepak、Dirac、DV、Indeo、Video、Pixlet、
RealVideo、RTVideo、SheerVideo、Smacker、Sorenson Video、Theora、VC-1、VP3、VP6、VP7、
VP8, VP9, WMV etc..Although these coded formats are of little use, also there are some equipment using, be no longer discussed in detail here.
Current encoder form is various, and what market share was higher is h264 coding, is in dominance, emerging volume
Code form has h265 and vp9, and both coded formats are ripe not enough, and most of security device still supports h264 form.
H.264 it is to set up on the basis of MPEG-4 technology, its encoding and decoding flow process mainly includes 5 parts：
Interframe and infra-frame prediction (Estimation), conversion (Transform) and inverse transformation, quantization (Quantization) and inverse
Change, loop filtering (Loop Filter), entropy code (Entropy Coding).
H.264 the main target of standard is：Compared with other existing video encoding standards, provide under identical bandwidth
More outstanding image quality.By this standard, the compression efficiency under equal image quality carried than former standard (MPEG2)
High 2 times about.
H.264 the sub-protocol form (algorithm) of 11 grades, 7 classifications can be provided, wherein tier definition is to outside
Environment is defined, for example bandwidth demand, memory requirements, network performance etc..Higher grade, and bandwidth requirement is higher, video
Quality is also higher.Class declaration is then for application-specific, defines the characteristic subset that encoder is used, and specification different application
Encoder complexity in environment.
H.264 maximum advantage is that have very high data compression ratio, under conditions of equal picture quality, H.264
Compression ratio be more than 2 times of MPEG-2, be 1.5～2 times of MPEG-4.Give an example, the size of original document if
88GB, becomes 3.5GB using after the compression of MPEG-2 compression standard, compression ratio is 25: 1, and after being compressed using H.264 compression standard
It is changed into 879MB, from 88GB to 879MB, compression ratio H.264 reaches surprising 102: 1.Low bit- rate (Low Bit Rate) is right
H.264 high compression ratio plays an important role, and compares with compress techniques such as MPEG-2 with MPEG-4ASP, H.264 compresses
Technology will greatly save the download time data flow charging of user.Especially it is noted that H.264 there is high compression
Than while also have the smooth image of high-quality, Just because of this, through the video data H.264 compressing, in network transmission
During required bandwidth less, also more economically.
