Description
Technical field
The present invention relates to Internet technical field, particularly to a kind of audio/video document play-back method and system.
Background technology
Along with the arrival of information age, audio-video document becomes important information carrier, current common audio frequency and video
Form includes:
MPEG series, MPEG is (Moving Pictures Experts Group) motion picture expert group,
Belong to ISO (International Organization for Standardization) International Standards Organization, they
Developing a series of video/audio coding, that the most familiar is exactly MP3, MPEG-1/2/4.
MPEG-1 is Video coding earlier, is mainly used in CD-ROM and stores video.MPEG-2 be
A kind of Video coding of exploitation on the basis of MPEG-1, its quality is far better than MPEG-1, so quilt
Being used in above DVD-Video, MPEG-2 is the Video coding that DVD-Video uniquely specifies.
MPEG-2 not only applies to DVD-Video, and major part HDTV (HDTV) is also adopted by
MPEG-2 encodes, and resolution has reached 1920x1080.Due to popularizing of MPEG-2, originally it was
The MPEG-3 that HDTV prepares finally declares to abandon.MPEG-4 is to tackle the environment such as network transmission,
Traditional MPEG-1/2 does not adapts to, so having promoted the birth of MPEG-4.MPEG-4 adopts
By series of new techniques, meet the demand transmitting higher video quality under low bandwidth.DivX, XviD,
MS MPEG4 is the MPEG-4 Video coding used, except the application on DVDRip,
3GPP has the most also received MPEG-4 as Video Coding Scheme.MPEG-4AVC is and MPEG-4
Being two kinds of different codings, AVC is more suitable for low-bandwidth transmission.On high code check, the performance of AVC is also
MPEG-4 to be better than, so the trend of present big substituted MPEG-4.HD DVD of future generation and
Blue Ray Disc the most formally receives AVC to be one of Video Coding Scheme.MPEG Audio Layer
1/2 namely MP1, MP2, earlier audio coding, is the predecessor of MP3, is mainly used in VCD,
The audio coding of DVD, SVCD.The i.e. MP3 of MPEG Audio Layer 3, has become as network audio
Main flow form, can be at the code check of 128kbps close to CD Quality.MPEG-2AAC is at MPEG-2
A kind of new audio coding of upper exploitation, and traditional MPEG Audio is incompatible, its mass theory
Upper higher than MP3, and support multichannel.In the range of code rates of 96kbps just can close to CD Quality,
Transmit than MP3 more properly code check.MPEG-4AAC AAC is as MPEG-4 standard
Audio coding, certain MPEG-4Audio also has other multiple audio codings.MPEG-4aacPlus
Have employed the AAC of SBR spectral band replication technology, SBR technology can allow audio coding reduce the code of half
Rate and tonequality does not have the biggest change, have become as a part for MPEG-4 standard.
DVD series, this refers to DVD-Video and DVD-Audio, also can relate to some HD DVD.
The coding of DVD broadly falls into application layer.Dolby Digital AC3 is the actual audio coding of DVD
Standard, now all of DVD uses it to compress audio frequency, it is provided that the output of maximum 5.1 sound channels is propped up
Hold, high-quality audio frequency can be stored in limited space.Dolby Digital Plus next generation HD DVD's
Audio coding, is the upgraded version of AC3, supports 7.1 even more sound channels, and range of code rates also has greatly
Width promotes.Lossless audio coding on MLP Lossless HD DVD, is similarly Dolby company and opens
Sending out, the highest sampling can reach 192KHz, is also the audio coding standard of DVD-Audio.DTS DTS
It is initially the audio system for cinema's exploitation, is the most just applied in DVD.DTS-HD is of future generation
The audio coding of HD DVD.LPCM is the pcm encoder not compressed, and can only store two sound channels,
But sample rate can be up to 96KHz, being the one that in DVD-Video, tonequality is best, certain volume is also
It is maximum.MPEG Audio is mainly MP2, is applied to the DVD of pal mode, and compression ratio is high,
Support multichannel (MPEG-2 specification all supports multichannel).DSD (Direct Stream Digital) is direct
Bit stream numeral, is released by Sony, it is possible to avoids the drawback of tradition pcm encoder, reaches the highest
Quality.The highest sampling is the same with DVD-Audio, 192KHz.
H.26X series is the international videotex of ITU (International Telecommunication Union)
The coding series that alliance is leading, is mainly used in live video communication field, such as video conferencing etc..Due to existing
Also begin to march to this field in MPEG series, so the two tissue has also begun to close cooperation,
Such as the most popular AVC/H.264, it is simply that by " VCEG (the Video Coding Experts under ITU
Group) Video Coding Experts group " and " ISO (International Organization for Standardization)
International Standards Organization " under " MPEG (Moving Pictures Experts Group) motion video is special
Family's group " produce jointly issue.H.261 be ITU-T be carry out on ISDN (ISDN) double
Formulating to acoustic image business (videophone, video conference), it is Moving picture compression standard the earliest,
It has formulated the various piece of Video coding in detail, including the inter prediction of motion compensation, dct transform, amount
The parts such as change, entropy code, and the rate controlled suitable with the channel of fixed rate.H.263 it is ITU-T
The video encoding standard formulated for the narrowband communication channel less than 64kb/s, it is to develop on the basis of H.261
Get up.H.263+ it is second version H.263, adds many new techniques and extend H.263
Range of application.H.263++ it is to add several option on H.263+, strengthens code stream on noisy channels
Error-resilient performance, simultaneously improve strengthen code efficiency.The most above-mentioned
MPEG-4AVC.H.264 it is new that the joint video team (JVT) being made up of ISO/IEC with ITU-T is formulated
Generation video compression coding standard.The named AVC of this standard (Advanced Video in ISO/IEC
Coding), as the 10th option of MPEG-4 standard；ITU-T is officially named and H.264 marks
Accurate.
3GPP video have employed MPEG-4 and H.263 two kinds of codings, may also will add H.264,
Audio frequency aspect music compression use AAC, voice then use advanced person AMR, another aacPlus along with
The release of V2 version, the effect under low bit-rate is more prominent.
Windows Media series is the audio frequency and video coding series that Microsoft Corporation is leading, going out of it
Existing primarily to carry out Network Video Transmission, the most march to HDTV aspect, develop WMV
HD applies.Microsoft MPEG-4v1/v2/v3 is the Video coding that ASF the earliest uses, based on
MPEG-4 technological development, DivX3.11 is namely based on what Microsoft MPEG-4v3 cracked out,
The most just rewritten.Windows Media Video 7 is first that Microsoft formally develops
Windows Media Video, starts departing from MPEG-4, and MPEG-4 is incompatible, and it is in compression
In speed very soon, present network has a lot of WMV using this format compression.Windows Media
The version that Video 8 improves on the basis of WMV7, does not enters many above quality.Windows Media
The opera involving much singing and action of Video 9 Microsoft, the most just this coding, a V9 series platform especially, allow Microsoft
There are the standardization bodies such as enough ability challenge MPEG, ITU.The application of particularly WMV HD, allows
Microsoft also ranks among video standard field.Windows Media Video 9Professional WMV HD should
Coding, and WMV9 is compatible, is optimized on high bit rate, and picture is the most outstanding.
Windows Media Video 9Screen static screen lossless compression-encoding, quality is the best, compression ratio
Height, just for environment as the least in changes such as screens.
RealMedia series is the serial coding techniques that RealNetworks is developed, and is also primarily used for net
Network transmits, and does well under ins and outs rate.RealVideo G2 is RealVideo coding in early days.
The video format that RealVideo 8 releases along with RealPlayer 8, is the Internet video coding of present main flow
One of.RealVideo 9 is a new generation's coding of RealNetworks exploitation, and quality progress is a lot, special
It not under low bit-rate, and coding rate is quickly, accomplished the fine unification of speed and matter.RealVideo 10
On the basis of RealVideo 9, add some parameters, such as EHQ etc., more accurately control code check, and
RealVideo 9 is compatible.
