Haivision Glossary: H.264 Video Compression

Motion JPEG (M-JPEG or MJPEG) is a video compression format in which each video frame or interlaced field of a digital video sequence is compressed separately as a JPEG image..

As the world of video compression evolved, not all the advancements came from the traditional powerhouses like MPEG or ITU-T. The rise of the internet brought about new

The desired compression algorithm may greatly influence the SOC selection for your embedded product. For example, if H.264 compression is selected, but the desired SOC

Each mode is a di“erent prediction algorithm, so we have to store which algorithm we chose in the video stream in order to decode it.

In this post we’re using H.264 as the archetypal compression standard. While it’s no longer the newest video compression format, it still provides a sufficiently detailed example for explaining

HEIF, AVC, H.264, H.265, HEIC and HEVC codecs explained

Video codecs use complex algorithms to “squeeze” common and redundant visual data from the video frames: Spatial Redundancy – Nearby pixels within a frame tend to be

You’re comparing two different things: A 48bit/px(16x3colors) stream and a YUV 420 8bit stream. H.264 (mostly) compress and decode 8bit YUV420. The H.264 encoder may pull down

The H.264 codec meaning refers to its role as an efficient video compression format that optimizes file size while maintaining visual quality. As a video standard, there are multiple implementations of the H.264 codec,

In this post we’re using H.264 as the archetypal compression standard. While it’s no longer the newest video compression format, it still provides a sufficiently detailed example for explaining

H.264 can compress video data using advanced techniques such as inter-frame compression and predictive coding. The compression process removes redundant information from consecutive video frames and represents

Lossless compression is a class of algorithms that will allow for the exact original data to be reconstructed from the compressed data. That means that a limited amount of techniques are

Beginner’s Guide to Encoding H.264

Explore the MPEG-4/H.264 video compression standard—its benefits, applications, and why it remains a top choice in digital media. MPEG-4, also known as H.264 or Advanced

which needs to be done at each stage in the compression algorithm. For example, a picture from a video stream at standard definition resolution (720×480) is divided into 1,350 (45×30)

The arithmetic coding scheme selected for H.264, Context-based Adaptive Binary Arithmetic Coding or CABAC, achieves good compression performance through (a) selecting probability

This beginner’s guide to encoding H.264 will describe what H.264 is, detail the critical compatibility-related parameters, and show how to encode to H.264 for adaptive bitrate streaming, live streaming, and creating mezzanine

At a high level, JPEG is a lossy image compression technique. What you may not realize is that achieving this required a fascinating blend of human perception,

A high level walkthrough of the basics of video compression techniques used in MPEG, AVC/H.264, codecs.

Each one of these steps will be explained in more detail and examples will be provided later in the text. Here’s a high-level block diagram for a video compression encoder in

Introduction to H.264 Advanced Video Coding

A video coding format [a] (or sometimes video compression format) is a content representation format of digital video content, such as in a data file or bitstream.It typically uses a

Video is composed of a stream of individual pictures that can be broken down into individual blocks of 16 pixels by 16 lines called “macroblocks”. This practice simplifies the processing

In this article, we explain the operation and characteristics of video codecs and the demands codecs make on processors. We also explain how codecs differ from one another

It begins with an introduction to pulse code modulation (PCM) and then describes μ-law and A-law compression standards which compress audio using companding algorithms. It also covers

When the video is generated by a CCTV camera, is necessary to compress it to save bandwidth and storage space. The compression is performed by a CCTV codec algorithm such as the

Commonly used for the recording, compression, and distribution of video content, the H.264 format is a network-friendly video transmission method that delivers high-quality images

compress a frame MB by MB. To compress an MB, we use a hybrid of three techniques: prediction, transformation & quantization, and entropy coding. The procedure works on a frame
