The Moving Picture Experts Group, more commonly known as MPEG, has been a driving force behind the digital media revolution. Since its inception in the late 1980s, MPEG has been instrumental in developing compression standards that have enabled the efficient transmission and storage of audio and video content. In this article, we will explore the history of MPEG, its impact on digital media, and the evolution of its compression standards. | Standard | Year | Formal Name |
The newest major standard, VVC, is incredibly computationally demanding. It can compress a 4K movie that HEVC made into 10 GB down to 5 GB with no visible loss. It introduces features like "intra-prediction" with 67 directional modes (vs. 33 on HEVC) and "adaptive motion vector resolution." VVC is designed for the next decade of immersive video, but widespread adoption (via hardware decoders in phones and TVs) will take time. 33 on HEVC) and "adaptive motion vector resolution
It achieves this through . The encoder divides the frame into macroblocks, finds where those blocks moved from the previous frame, and simply encodes a short motion vector: “Block A moved 5 pixels right and 2 pixels up.” This can compress a video by 90-99% with often imperceptible quality loss. how it works
Without MPEG, the video streaming revolution would not exist. There would be no YouTube, no TikTok, no Zoom. This article dives deep into the world of MPEG—its history, how it works, its major standards, and its future in an era of AI and immersive reality.
