MPEG-1: Here is the first audio and video compression technique that was started in 1993, also known as the lossy file format and was designed to encode the audio and video file in Compact Disk (CD) bitrate. And move. Its most use is of low-quality DVD and Video CD.

MPEG-2: This is the second version of MPEG in which both video compression and transmission technique has improved and low-quality audio and video files have reached broadcast-quality television. It came on the market in 1995 and since then Dish Network, Blue-ray video, and digital satellite TV services started.
