About

It is widely used for audio and video encoding and decoding in multimedia applications. The format was designed to provide high-quality audio and video while maintaining low bandwidth requirements for efficient transmission over networks and storage on devices. MPEG-4 supports various features, including video and audio streaming, object-oriented composition, and interactive multimedia. It allows for the integration of different media types, such as text, graphics, and 2D/3D animations, into a single compressed file. This flexibility makes it suitable for a wide range of applications, including internet streaming, video conferencing, virtual reality, and broadcasting. The MPEG-4 standard encompasses multiple parts, each defining different aspects of the format. Part 2, known as Advanced Simple Profile (ASP), is widely used for video compression and is the basis for popular formats like DivX and Xvid. Part 10, also known as Advanced Video Coding (AVC) or H. 264, is a more recent addition that offers further improvements in compression efficiency and video quality. In addition to video compression, MPEG-4 also includes audio compression methods, such as Advanced Audio Coding (AAC) and its variants, which provide high-quality audio at low bitrates. These audio codecs are widely used in various applications, including streaming services, digital radio, and mobile devices. MPEG-4 has had a significant impact on multimedia technology and has become a standard for video compression in various industries. It has enabled the widespread distribution of video content over the internet, providing users with access to high-quality videos on various devices. The format continues to evolve, with advancements like High Efficiency Video Coding (HEVC or H. 265) being developed to further improve compression efficiency and support higher resolutions and frame rates.
