Blog | The History of Video Compression Standards, From 1929 Until Now
Video compression reduces the total number of bits you need to represent an image or video. Over the years people have come up with many different algorithms for compressing video. While video compression seems very modern, it has a long history that begins with analog video. In our review of the history of video compression, we’ll stop at some major milestones that brought us to where we are today. You’ll notice that in the beginning, new developments are concepts, then eventually these become various video compression standards. Many of these standards are used today, and people continue to develop new and improved ones all the time.
1929: The First Appearance of Interframe Compression
Surprisingly, the first discussion of interframe compression happened way back in 1929. Interframe compression is the idea of saving a key image, and then only saving changes to that image as they occur from frame to frame. The initial frame used to compare the others to is called the keyframe. R.D. Kell proposed this concept for use with analog video, but this concept persists and is used today with digital video!
