Mpeg

MPEG-4 was an ambitious umbrella standard, but Part 2 (Visual) was the star. It introduced object-based coding—the ability to treat different elements of a scene (foreground person, background) separately. However, its main impact was enabling high-quality video at file sizes smaller than MPEG-2. Codecs like DivX and Xvid (open-source) allowed pirates and early video enthusiasts to rip DVDs to 700 MB files that fit on a CD. This paved the way for the internet video era, though it was quickly surpassed.

The Goal: Universal, high-efficiency video for everything from low-res phones to 4K Blu-ray. Key Products: Blu-ray Disc, YouTube, Netflix, Zoom, FaceTime, Adobe Flash. MPEG-4 was an ambitious umbrella standard, but Part

The impact of MPEG on digital media has been profound. The development of compression standards has enabled the efficient transmission and storage of audio and video content, driving the growth of digital media industries such as: Codecs like DivX and Xvid (open-source) allowed pirates

MPEG-4 introduced a number of innovative features, including object-based compression, which allowed for the compression of individual objects within a scene, rather than the entire scene itself. This standard also introduced a new level of interactivity, enabling users to manipulate and interact with compressed audio and video content. Key Products: Blu-ray Disc
