View source for MPEG-4 Part 2

== Overview ==
[[MPEG-4 Part 2|Moving Picture Experts Group-4 Part 2]] (MPEG-4 Part 2), also known as MPEG-4 Visual, is a video compression format introduced by the [[Moving Picture Experts Group|MPEG]] in 1999. It is a member of the MPEG-4 standard and has been widely used in various applications, including broadcasting, internet streaming, and video conferencing. 

== History ==
The development of MPEG-4 Part 2 began in the late 1990s as part of the broader [[MPEG-4|MPEG-4 standard]]. The goal was to create a versatile video compression format that could cater to a wide range of applications, from low bitrate mobile streaming to high-quality broadcast. MPEG-4 Part 2 was eventually published in 1999 and has since been adopted in numerous applications worldwide.

== Technical Details ==
MPEG-4 Part 2 uses a variety of techniques to achieve high-quality video compression. These include [[Discrete cosine transform|Discrete Cosine Transform]] (DCT), [[Motion compensation|motion compensation]], and [[Quantization (signal processing)|quantization]]. It also supports a range of features such as interlaced video, scalability, and error resilience, making it suitable for a wide range of applications.

== Applications ==
MPEG-4 Part 2 has been widely used in a variety of applications. These include digital television broadcasting, internet video streaming, video conferencing, and mobile video. It is also used in various video storage formats, including DVD and Blu-ray.

== Advantages and Limitations ==
One of the main advantages of MPEG-4 Part 2 is its versatility. It supports a wide range of video resolutions, bitrates, and frame rates, making it suitable for a variety of applications. It also provides good video quality at low bitrates, which is particularly useful for mobile video streaming and video conferencing.

However, MPEG-4 Part 2 also has some limitations. For instance, it is less efficient than newer video compression standards such as [[H.264|MPEG-4 Part 10 (H.264)]] and [[High Efficiency Video Coding|HEVC (H.265)]]. This means that it requires higher bitrates to achieve the same video quality.
