MPEG-4 
Advanced compression scheme finalized October 1998, designed to enable transmission and reception of high-quality audio and video over the Internet and next-generation mobile telephones; potentially enables mobile video phones, video e-mail, and cordless video cameras. Two major versions are MPEG-4 Simple Profile for low-resolution digital video content, usually for distribution over the Internet, and MPEG-4 AVC (Advanced Video Coding), which offers faster and higher-quality compression than MPEG-2 for HDTV content.
