MPEG-2 is a video coding format, first standardized in 1995 and revised in 2013. Due to relatively low computational complexity this standard gained popularity and massive native implementations in video hardware. Hence MPEG-2 has actually become a standard in satellite and cable broadcasting. MPEG-2 is also used for creating DVDs for the same reasons (native hardware support by DVD players).

MJPEG is a format of multimedia data, which uses a frame-by-frame video track compression technology JPEG. This codec does not encode the difference (movement) between frames, whereby the image in some places does not turn out smooth enough. The main advantage of this format is the low requirements to hardware computational power, which, in turn, leads to a low level of compression and a larger resulting file size. It is actively used in web and IP-cameras.
