The document discusses the H.264 video compression standard. It provides an overview of the standard, including its objectives to improve compression performance over previous standards. Key features that allow for superior compression compared to other standards are described, such as enhanced motion estimation and an improved deblocking filter. Performance comparisons show H.264 can provide bit rate savings of up to 50% compared to other standards like MPEG-2 and H.263.
The latest video compression standard, H.264 (also known as MPEG-4 Part 10/AVC for Advanced Video
Coding), is expected to become the video standard of choice in the coming years.
H.264 is an open, licensed standard that supports the most efficient video compression techniques available
today. Without compromising image quality, an H.264 encoder can reduce the size of a digital video file by
more than 80% compared with the Motion JPEG format and as much as 50% more than with the MPEG-4
Part 2 standard. This means that much less network bandwidth and storage space are required for a video
file. Or seen another way, much higher video quality can be achieved for a given bit rate.
Video coding is an essential component of video streaming, digital TV, video chat and many other technologies. This presentation, an invited lecture to the US Patent and Trade Mark Office, describes some of the key developments in the history of video coding.
Many of the components of present-day video codecs were originally developed before 1990. From 1990 onwards, developments in video coding were closely associated with industry standards such as MPEG-2, H.264 and H.265/HEVC.
The presentation covers:
- Basic concepts of video coding
- Fundamental inventions prior to 1990
- Industry standards from 1990 to 2014
- Video coding patents and patent pools.
In October 2017, ISO/IEC JCT1 SC29/WG11 MPEG and ITU-T SG16/Q6 VCEG have jointly published a Call for Proposals on Video Compression with Capability beyond HEVC and its current extensions. It is targeting at a new generation of video compression technology that has substantially higher compression capability than the existing HEVC standard. The responses to the call are evaluated in April 2018, forming the kick-off for a new standardization activity in the Joint Video Experts Team (JVET) of VCEG and MPEG, with a target of finalization by the end of the year 2020. Three categories of video are addressed: Standard dynamic range video (SDR), high dynamic range video (HDR), and 360° video. While SDR and HDR cover variants of conventional video to be displayed e.g. on a suitable TV screen at very high resolution (UHD), the 360° category targets at videos capturing a full-degree surround view of the scene. This enables an immersive video experience with the possibility to look around in the rendered scene, e.g. when viewed using a head-mounted display. This application triggers various technical challenges which need to be addressed in terms of compression, encoding, transport, and rendering. The talk summarizes the current state of the complete standardization project. Focussing on the SDR and 360° video categories, it highlights the development of selected coding tools compared to the state of the art. Representative examples of the new technological challenges as well as corresponding proposed solutions are presented.

Audio Compression Techniques
a type of lossy or lossless compression in which the amount of data in a recorded waveform is reduced to differing extents for transmission respectively with or without some loss of quality, used in CD and MP3 encoding, Internet radio.
Dynamic range compression, also called audio level compression, in which the dynamic range, the difference between loud and quiet, of an audio waveform is reduced
This paper deals with the overview of latest video coding standard High-Efficiency Video
Coding (HEVC). Also this work presents a performance comparison of the two latest video coding

In familiar applications such as digital versatile disc (DVD), digital video can be found in digital TV, Internet video streaming, digital high-definition television is defined formula. Digital video sharing digital format all functions, including lossless transmission, lossless storage, easy to edit.Currently in many applications, including video conferencing, video games entertainment, DVD discs, digital video broadcasting. As digital video compression format storage requirements prohibitive, lossy digital video compression technology commonly used as the data transmission rate and a compromise between quality. In this paper, we compare and analyze the MPEG-2 , H.261 and H.264 video compression standards.After the Compression , We get the result that the compression of H.264 is better than other two but it take much time as compare to H.261 on higher cost.
PERFORMANCE EVALUATION OF H.265/MPEG-HEVC, VP9 AND H.264/MPEGAVC VIDEO CODINGijma
This study evaluates the performance of the three latest video codecs H.265/MPEG-HEVC, H.264/MPEGAVC
and VP9. The evaluation is based on both subjective and objective quality metrics. The assessment
metric Double Stimulus Impairment Scale (DSIS) is used to evaluate the subjective quality of the
compressed video sequences. The Peak Signal-to-Noise Ratio (PSNR) metricis used for the objective
evaluation. Moreover, this work studies the effect of frame rate and resolution on the encoders’
performance. The extensive number of experiments are conducted with similar encoding configurations for
the three studied encoders. The evaluation results show that H.265/MPEG-HEVC provides superior bitrate
saving capabilities compared to H.264 and VP9. However, VP9 shows lower encoding time than
H.265/MPEG-HEVC but higher encoding time compared to H.264.
A REAL-TIME H.264/AVC ENCODER&DECODER WITH VERTICAL MODE FOR INTRA FRAME AND ...csandit
The video coding standards are being developed to satisfy the requirements of applications for
various purposes, better picture quality, higher coding efficiency, and more error robustness.
The new international video coding standard H.264 /AVC aims at having significant
improvements in coding efficiency, and error robustness in comparison with the previous
standards such as MPEG-2, H261, H263,and H264. Video stream needs to be processed from
several steps in order to encode and decode the video such that it is compressed efficiently with
available limited resources of hardware and software. All advantages and disadvantages of
available algorithms should be known to implement a codec to accomplish final requirement.
The purpose of this project is to implement all basic building blocks of H.264 video encoder and
decoder. The significance of the project is the inclusion of all components required to encode
and decode a video in MatLab .

• A profile defines a set of coding tools or algorithms
that can be used in generating a compliant bit-stream.
• All decoders conforming to a specific profile have to
support all features in that profile.
• Encoders are not required to make use of any
particular set of features supported in a profile but
have to provide conforming bit-streams.
