The ground of seat.
So-called Video coding mode just refers to through specific compress technique, and the file of some video format is converted into separately
A kind of mode of video format file.In video flowing transmission mostly important 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, International Organization for standardization
Column standard, be furthermore widely used on the internet there are also the WMV of the RealVideo of Real-Networks, Microsoft with
And QuickTime of Apple company etc..
It include at present as follows than major coded format.
H.26X series (leading by ITU [international videotex alliance]) include H.261, H.262, H.263, H.264,
H.265:
(1) H.261: mainly being used in old video conference and videophone products
(2) H.263: being used primarily in video conference, visual telephone and network video
(3) H.264:H.264/MPEG-4 Part X or AVC (Advanced Video Coding, advanced video
Coding), it is a kind of video compression standard, a kind of recording for the high-precision video being widely used, compression and publication format.
(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 promoting picture quality, while can also reach
H.264/MPEG-4 twice of AVC of compression ratio (being equal to bit rate under same image quality reduces 50%) can support 4K points
Resolution even arrives super hd-tv, and highest resolution can reach 8192 × 4320 (8K resolution ratio), this is becoming of developing at present
Gesture.Until 2013, Potplayer is added to the decoding for H.265 video, and there has been no the appearance of popular encoding software.
MPEG series (is developed) video by the MPEG [motion picture expert group] of ISO [mechanism, International Standards Organization] subordinate and compiled
Code aspect mainly has:
(1) (MPEG-1 second part is mainly used on VCD MPEG-1 second part, some Online Videos also use this
Kind format.The quality of the codec is generally suitable with original vhs video band.)
(2) (H.262 MPEG-2 second part is equal to MPEG-2 second part, using in DVD, SVCD and most of numbers
In word video broadcast system and cable distribution systems (cable distribution systems).)

VP8, VP9, WMV etc..Although these coded formats are of little use, but there are also equipment to use, and are no longer discussed in detail here.
Current encoder format is various, occupation rate of market it is relatively high be h264 coding, be in dominance, emerging volume
Code format has h265 and vp9, both coded formats are not mature enough, and most of security device still supports h264 format.
H.264 it is to be set up on the basis of MPEG-4 technology, encoding and decoding process mainly includes 5 parts:
Interframe and intra prediction (Estimation), transformation (Transform) and inverse transformation, quantization (Quantization) and inverse
Change, loop filtering (Loop Filter), entropy coding (Entropy Coding).
H.264 the main target of standard is: compared with other existing video encoding standards, providing under identical bandwidth
More outstanding image quality.By the standard, the compression efficiency under same image quality is mentioned than pervious standard (MPEG2)
It is 2 times or so high.
H.264 the sub-protocol format (algorithm) of 11 grades, 7 classifications can be provided, wherein tier definition is to outside
Environment is defined, such as bandwidth demand, memory requirements, network performance etc..Higher grade, and bandwidth requirement is higher, video
Quality is also higher.Class declaration is then to define characteristic subset used in encoder, and specification different application for specific application
Encoder complexity in environment.
H.264 maximum advantage is that have very high data compression ratio, under conditions of same picture quality, H.264
Compression ratio be MPEG-2 2 times or more, be 1.5~2 times of MPEG-4.For example, the size of original document if it is
88GB, using becoming 3.5GB after the compression of MPEG-2 compression standard, compression ratio 25: 1, and after using H.264 compression standard compression
Become 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 to be compared with MPEG-2 with compress techniques such as MPEG-4ASP, is H.264 compressed
Technology will greatly save download time and the data flow charging of user.Especially it is noted that H.264 with high compression
