Digital Video Compression Systems and Standards

Digital video compression systems and standards are used to compress video data to reduce the size of video files and enable efficient storage and transmission of video content over networks. There are several video compression systems and standards in use today, including:

H.264/AVC (Advanced Video Coding): This is a widely used video compression standard that delivers high-quality video at lower bit rates. It is used for various applications, including Blu-ray discs, satellite and cable TV, and streaming video over the internet.

HEVC/H.265 (High-Efficiency Video Coding): This is the successor to H.264/AVC and provides even better compression while maintaining high-quality video. It is used for 4K and 8K video streaming and distribution, as well as for video surveillance and video conferencing.

MPEG-2 (Moving Picture Experts Group): This is a widely used video compression standard that is used for DVD and satellite and cable TV broadcasting.

MPEG-4: This is a flexible video compression standard that supports various multimedia applications, including video streaming, video conferencing, and digital television.

VP9: This is a video compression standard developed by Google that is used for online video streaming, including on YouTube.

AV1: This is an open-source video compression standard developed by the Alliance for Open Media, which includes companies like Google, Amazon, and Netflix. It is designed to provide high-quality video compression while remaining royalty-free.

These are just a few of the many video compression systems and standards available today. The choice of which standard to use depends on factors such as the application, the desired video quality, and the available network bandwidth.
