Multimedia technologies

Video compression encodes video to reduce its size. Compressed video takes up less storage space and consumes less bandwidth when transmitted. Without video compression, a 3-hour 4K movie could take 15 days to download over a typical home broadband connection.

H.264, H.265 and H.266 are succeeding generations of video compression technologies. Each generation roughly doubled the efficiency of its predecessor, allowing the same video quality to be transmitted or stored using half the bandwidth or space.

• H.264 or Advanced Video Coding (AVC) was standardized in 2003 and is now the most widely used video format in the world. It drove standard and HD video streaming for a decade.
• H.265 or High-Efficiency Video Coding (HEVC) was introduced in 2013 to support the increasing demand for 4K video streaming and storage. It is now widely support on smartphones, web browsers, TVs and streaming platforms.
• H.266 or Versatile Video Coding (VVC) is the next-generation video standard. It supports not only the needs of 8K streaming but also immersive reality and 360° video.

MPEG-I is an immersive audio standard, the first to provide 6-degrees-of-freedom (6DoF) audio listening experiences. It lets you move naturally and interact with virtual or augmented worlds while fully immersed in ambient sound.

Immersive Voice and Audio Services (IVAS) is an audio codec that enables live spatial audio transmission across devices such as smartphones over 5G networks.
