![]() H.264 uses an efficient codec that provides high-quality images and uses minimal bandwidth. Lower bandwidth usage and higher resolution monitoring – It provides high-quality transmission of full-motion video with lower bandwidth requirements and lower latency than traditional video standards like MPEG-2.The H.264 video coding and decoding process is shown below. Further, this information will be used to reverse the coding process and recreate a sequence of video images. 264 bitstream, decodes each syntax element, and extracts the information like quantized transform coefficients, prediction information, etc. Now, the H.264 video decoder performs complementary processes like decoding, inverse transform, and reconstruction to produce a decoded video sequence. The output will be macroblocks that consist of block sizes as large as 16×16 pixels. It utilizes a block-oriented standard with motion competition to process frames of video content. The H.264 video encoder performs prediction, transformation, and encoding processes to produce a compressed H.264 bitstream. Sometimes, an H.264 video is encoded with audio compressed with the Advanced Audio Coding (AAC) codec, an ISO/IEC standard (MPEG4 Part 3). MP4 extension, as well as QuickTime (.MOV), Flash (.F4V), 3GP for mobile phones (.3GP), and the MPEG transport stream (.ts). Hence, it is widely used in cable TV broadcasting and Blu-ray disks.Īs a video codec, H.264 is frequently produced in the MPEG-4 container format, which uses the. ![]() It delivers good video quality at lower bitrates compared to previous standards. This codec is an industry standard for video compression that helps creators record, compress, and distribute their online videos. Nowadays, H.264 codec is most commonly used in video streaming. It is a video compression technology jointly developed by the International Telecommunications Union (as H.264) and the International Organization for Standardization/International Electrotechnical Commission Moving Picture Experts Group (as MPEG-4 Part 10, Advanced Video Coding, or AVC). H.264 is also called Advanced Video Coding (AVC) or MPEG-4 Part 10. Since the scope of this article is limited to H.264, let us now look at it in detail in the next section. There are hundreds of different codecs such as:Īmong these codecs, H.264/AVC and H.265/HEVC codecs are commonly used in embedded cameras.
