video decoding

A video codec refers to a program or device that can compress or decompress digital video. Usually this type of compression is lossy data compression. Historically, video signals were stored in analog form on magnetic tape. With the emergence of Compact Disc and its entry into the market, audio signals were stored digitally, video signals also began to use digital formats, and some related technologies began to develop accordingly. Both audio and video require customizable compression methods. Engineers and mathematicians have tried many different ways to try to solve this problem.
