3GPP
3GP is an audio and video container format that is generally used in 3G cell phones. But it can also work in 2G and 4G cell phones. This MP4 based container broadcasts multimedia files between cell phones over internet.
MKV
MKV (Matroska video File) is a video container format that supports more than one audio and subtitle tracks at the same file. It is based on Extensible Binary Meta Language. It supports several video and audio compression formats. The difference between MKV file types with most other video extensions is that it is a container, not a codec.
